Description

A kind of combustion chamber system of IC engine

The present invention relates to a kind of chamber system of internal-combustion engine, but especially relate to a kind of combustion chamber system of IC engine of combustion chamber volume controlled change.

The volume and the compression ratio of the firing chamber of the internal-combustion engine that generally uses all are immutable at present, this compression-ignited gasoline engine and compression-ignited diesel engine in fixing air inflow is reasonably, but makes the internal-combustion engine of mixture combustion just unreasonable with the spark ignition systems igniting.Because light a fire with spark ignition systems owing to this, it all is immutable making the compression ratio of internal-combustion engine of mixture combustion and the volume of firing chamber, and air inflow and fuel delivery need wide variation, but no matter how air inflow and fuel delivery change, and at the end the waste gas residual quantity is constant substantially in exhaust stroke.The mixed gas that is at the end sucked when suction stroke under low-power running (be throttle opening hour) situation is thinner, ratio when the ratio of waste gas and mixed gas is big far above throttle opening, and because throttle opening is less, at the end the gas in the effective cylinder volume is thin in suction stroke, and compression stroke at the end the pressure and temperature of gas also far below normal value, also promptly this moment to effective pressed density of mixed gas far below normal value, so it is incomplete fuel combustion to occur under this working state, the thermal efficiency reduces, oil consumption increases, the blowdown aggravation, even cutoff, low temperature starts difficulty down, each work cycle many bad phenomenon such as instability extremely when using weak mixture.Therefore, just can make the thermal efficiency of fuel reach the highest under a series of perfect conditions such as all immutable internal-combustion engine of this combustion chamber volume and compression ratio only is suitable for when maximum valve opening, normal barometric pressure, normal temperature, rated speed, blowdown is minimum.Obviously, Vehicular internal combustion engine does not have so desirable Environmental Conditions at all.On the other hand, also can make the employed fuel type of internal-combustion engine be subjected to great restriction with the igniting of spark ignition system, for example: compression ratio can only use the gasoline of label more than 90# at the petrol engine more than 9, and can not use such as kerosene, alcohol, diesel oil and be lower than the gasoline of 90#.

The characteristic fuel used according to internal-combustion engine contracts than limiting within the specific limits the maximal pressure of the internal-combustion engine of mixture combustion with the spark ignition systems igniting.When this limited value only is suitable for maximum output (throttle opening maximum and when rated speed), throttle opening does not just meet above condition less than maximum value or when running up.Often be between the 40%-70% when motor petrol internal-combustion engine generally speaking, the throttle opening underloading of lorry internal-combustion engine, sedan car is between 30%-60%, and throttle opening was then littler when smooth and pavement behavior was bad when urban transportation.In this case and do not require the peak output of internal-combustion engine, more pay attention to the high efficiency and low pollution of internal-combustion engine.This shows fuel saving in a large number if gasoline engine can reduce oil consumption under the little aperture situation of closure.Under this operating mode, use conventional methods at present and can't improve the thermal efficiency, can only adopt other method to reduce exhaust pollution, but these methods all can not tackle the problem at its root.Suitably improving compression ratio under the little aperture situation of closure can fundamentally address the above problem.When strengthening, correspondingly reduces throttle opening compression ratio again, so that can proper functioning when the high-power output of needs thereupon.In addition, the working environment of internal-combustion engine is changeable, Vehicular internal combustion engine is all the more so, the height of temperature, the height of internal combustion engine body temperature, the variation of height above sea level, the rotating speed of internal-combustion engine, use different fuel all to require the compression ratio of internal-combustion engine that corresponding the variation taken place, so just can make internal-combustion engine fuel efficiency under multiple environment, multiple condition reach peak, reduce noxious gas emission.

Generally speaking, make internal-combustion engine efficiency operation under various changeable situations of combustion mixture, its compression specific energy is changed with changeable factor, no matter there is above-mentioned various factors, as long as its compression ratio of control, the mixed gas that makes its employed fuel contracts more too high and spontaneous combustion prematurely can achieve the above object than not occurring Yin Wendu down at the maximal pressure that allows.

1, the internal combustion engine start course of work

The opening power primary path makes computer system processor program mainboard add the work power supply, and computer system is carried out program initialization, Hydraulic control system performance element and air throttle performance element are carried out self check, stepper motor is turned to, when detecting to closing direction During the air throttle initial position, make again stepper motor to evolution to turning to, treat that air throttle reaches the position slightly bigger than idling operation and (works as heat Should suitably reduce throttle opening when car starts) time stops, and enters then working procedure, waits for effector's input control signal. At first the effector imports enabling signal, and computer system is sent enabled instruction, and the internal combustion engine start performance element sends enabling signal and makes Starter circuit working, internal combustion engine begin to rotate under the dragging of starter motor, simultaneously by computer system control to the electric heating point Fire sheet energising heating. At this moment, divide manifold solenoid valve to open, pressure release electromagnetic valve, auxiliary pressure release electromagnetic valve and the unidirectional electromagnetism of maintenance pressure Valve cuts out, and the combustion chamber is in the only amount of volume and constant, and electric heat ignition sheet temperature should be heated to the temperature near the fuel burning-point Degree, this temperature is by electric heat ignition sheet mean temperature sensor and computer system co-controlling. Computer system is fetched a little The combustion difference, internal combustion engine operation is several should normally to be started after turning to. Fail behind some the turning to start if turn round, the computer system processor unit will Start the air throttle stepper motor, make it to being rotated to an angle to general orientation by little, throttle opening suitably increases advances gaseous mixture Tolerance also suitably strengthens, thereby has suitably improved compression travel temperature at the end, further improves simultaneously electric heat ignition sheet temperature, Make internal combustion engine start. At this moment, computer system is fetched and is lighted difference, and this value should be in OK range, and this value is too little, then explanation In advance combustion phenomena be about to appear in gaseous mixture, should start the air throttle stepper motor by computer system control, makes it to by greatly to little Direction rotation certain angle, throttle opening suitably reduce to make the gaseous mixture air inflow also suitably to reduce; This value is too big, and then explanation still The leeway of improving compression ratio is arranged, should by the computer system control hydraulic control system, its hydraulic pressure chamber suitably be increased again, and burn The chamber suitably reduces, and lights difference and is controlled in the OK range. After the internal combustion engine normal operation, opened by the computer system control cut-out Moving signal is tested the each several part temperature when reaching normal value when computer system, and the computer system processor unit controls reduces automatically Throttle opening is adjusted combustion chamber volume and electric heat ignition sheet temperature according to lighting difference again to idle position, and it is rested on Suitable compression ratio position. Fail after turning to start as internal combustion engine operation is some, then by the automatically controlled spray of computer system processor unit controls Oil system suitably strengthens mixture strength, continues to start. Still fail after turning to start as internal combustion engine operation is some, then by department of computer science The system processing unit is sent alarm signal, prompting internal combustion engine fault. Overall process starts the time spent not all by computer system control at every turn Surpassed for 15 seconds. The foot throttle pedal is inoperative in the internal combustion engine start process. 2, idling for internal combustion engine operating mode

After the internal combustion engine start preheating, when idling operation, because rotating speed is low, each stroke time spent is longer, again because of the design's internal combustion The compression ratio of machine in trifle valve opening situation is very high, and namely the shared volume in combustion chamber is very little, and at the end waste gas is residual in instroke Allowance is far fewer than the waste gas residual quantity of large-scale combustion chamber, even appearance is poured in down a chimney phenomenon because of the too high waste gas that takes place of vacuum in the admission passage, Still many than the waste gas less residue of large-scale combustion chamber can use lean mixture in this case. In addition, owing to each The stroke time spent is longer, and therefore flame propagation velocity, can suitably be adjusted also much larger than piston movement speed when using lean mixture Compression ratio and suitable adjustment electric heat ignition sheet temperature make lights the difference prolongation, and this can make fuel efficiency greatly improve (with respect to big combustion Burn the chamber, the rich mixture situation). Owing to used lean mixture, carbon monoxide content also can reduce greatly in the waste gas after the burning. Therefore, the electronic control injection system can change out lean mixture (the Computer Processing original program is changed) into, and other parts are adjusted accordingly. 3, internal combustion engine accelerates the course of work

Internal combustion engine start rear treadle throttle plate begins to work under the computer system processor unit controls, when the user depresses foot-operated Behind the throttle plate, through the analog-to-digital conversion unit that the foot throttle sensor passes to computer system to the degree that changes and rate of change, warp Deliver to the computer system processor unit after the analog-to-digital conversion, after being about to depress the degree of depth of foot throttle plate and rate of change and being quantized into data Deliver to the computer system processor unit, depress the desired output power of internal combustion engine value of depth representing user of foot throttle plate, and The rate of change that depresses the foot throttle plate then represents the speed value that the desired internal combustion engine output speed of user changes, and represents internal combustion with M The machine output power value, M value and throttle opening are linear, represent to depress the rate of change of foot throttle plate, computer with S System processing unit is compared with the M value that the last time obtains after receiving these two values that changed, and the value that obtains is that canonical shows Improve output power of internal combustion engine. At first will send instruction to the electronic control injection system, changing lean mixture is economic mixture gas area, right After rushing down pressure electromagnetic valve, divide manifold solenoid valve and keeping pressure Unidirectional solenoid valve output action to refer to the hydraulic control system performance element again Order makes and rushes down pressure electromagnetic valve and divide manifold solenoid valve to open, and keep the pressure Unidirectional solenoid valve to close, at compression travel and working stroke Pressure under make steel the shape of combustion chamber lid to the hydraulic pressure chamber Direction distortion, force hydraulic oil to be back to fuel tank through the draining pipeline, Combustion chamber volume increases gradually, and the hydraulic pressure chamber pressure sensor constantly passes pressure changing and the physical quantity of lighting the difference moment Give analog-to-digital conversion unit and the switching value input block of computer system, again by control joint after the computer system processor cell processing Valve and hydraulic control system coordination are sent action command to the air throttle performance element again, and the air throttle stepper motor is driven Throttle opening is opened to big direction by little, until the aperture of air throttle is just stopped when adapting with the degree of depth that depresses the foot throttle plate End. In this process if there is lighting that difference moves closer to or during less than predetermined value, illustrate to be about to take place in advance combustion phenomena, The computer system processor unit sends to the air throttle performance element immediately and stops action command, makes the air throttle stepper motor stop to move Do, until light difference when getting back in the preset range, begin again action. When the aperture of air throttle with depress the dark of foot throttle plate Degree is when adapting, and the computer system processor unit sends instruction to the executing agency of rushing down pressure electromagnetic valve, make to rush down pressure electromagnetic valve and close, Combustion chamber volume stops to increase, and also makes simultaneously to be subjected to the programme controlled stepper motor of computer system to stop action, and this after-burner holds Long-pending and throttle opening remains unchanged. The computer system processor unit judges whether to open the auxiliary piezoelectricity magnetic that rushes down according to the size of S value Valve and keep the pressure Unidirectional solenoid valve is more then opened such as the S value, hydraulic oil under the pressure of compression travel and working stroke, warp Rush down pressure electromagnetic valve, assist and rush down pressure electromagnetic valve, keep the pressure Unidirectional solenoid valve and divide manifold solenoid valve to be back to hydraulic oil tank, hydraulic pressure Indoor hydraulic oil can be discharged more rapidly, thereby makes the hydraulic pressure chamber volume reduce rapidly combustion chamber volume is increased rapidly, simultaneously also Make and opened fast to big direction by little by the programme controlled stepper motor drive of computer system air throttle. So just, in having finished The quick acceleration course of work of combustion machine. 4, the internal combustion engine deceleration course of work

When the user unclamps or reduces the foot throttle plate and depress the degree of depth, through the foot throttle sensor the degree and the rate of change that change Pass to the analog-to-digital conversion unit of computer system and after analog-to-digital conversion, deliver to the computer system processor unit, be about to depress foot-operated The altered depth dose of throttle plate is delivered to the computer system processor unit after changing into data, still represents output power of internal combustion engine with M Value represents to depress the rate of change of foot throttle plate with S, after these two values that changed are received in the computer system processor unit, with The M value that last time obtains is compared, and the value that obtains will reduce output power of internal combustion engine for negative then showing, is at first processed single by the calculation machine Unit sends action command to the air throttle performance element, makes moved by programme controlled stepper motor, drive throttle opening by greatly to Little direction is closed, and then to the rushing down pressure electromagnetic valve and divide the instruction of manifold solenoid valve output action of hydraulic control system performance element, makes and rush down Pressure electromagnetic valve and shunting closed electromagnetic valve force hydraulic oil by keeping the pressure Unidirectional solenoid valve under the pressure that oil pump produces, and advance Oil-piping flows into hydraulic pressure chamber, makes the shape of combustion chamber lid of steel to the combustion chamber Direction distortion, make combustion chamber volume begin to reduce from And improving gradually compression ratio, the hydraulic pressure chamber pressure sensor is constantly passed to calculating with pressure changing and the physical quantity of lighting difference The analog-to-digital conversion unit of machine system and switching value input block are again by the machine of calculation processing unit control air throttle and hydraulic control system Coordination makes and lights the difference maintenance in the reasonable scope, until the aperture of air throttle is mutually suitable with the degree of depth that depresses the foot throttle plate At once just stop. By calculate machine processing unit branch manifold solenoid valve opened, make to keep the pressure Unidirectional solenoid valve to close, from oil pump thereafter The hydraulic oil that pumps flows back to hydraulic oil tank through flow divider, and combustion chamber volume begins to remain unchanged. In this process if there is Light that difference moves closer to or during less than predetermined value, the computer system processor unit sends to the hydraulic control system performance element and stops Action command is opened the branch manifold solenoid valve, makes to keep the pressure Unidirectional solenoid valve to close, and the hydraulic oil that pumps from oil pump is through flow divider Flow back to fuel reserve tank, combustion chamber volume stops to reduce action, until when lighting difference greater than predetermined value, begin action again. Work as solar term When the aperture of door adapted with the degree of depth that depresses the foot throttle plate, the computer system processor unit was to the executing agency of rushing down pressure electromagnetic valve Send instruction, make and rush down pressure electromagnetic valve and close, also make simultaneously to be subjected to the programme controlled stepper motor of computer system to stop action, after this Combustion chamber volume and throttle opening remain unchanged. So just, finished the deceleration course of work of internal combustion engine. The change of combustion chamber volume Change the variation that slightly lags behind air throttle, this process is to reduce earlier throttle opening to reduce combustion chamber volume again, improves gradually compression Ratio. 5, engine load increases the weight of the work for the treatment of process

When output power of internal combustion engine is lower than a certain ratio (such as 80%) of peak power usually, should make in order to keep its economic performance Use lean mixture, when load increases the weight of (for example heavy haul and rapid upward slope), computer system is according to two sensors that are installed with on the flywheel---maximum is lighted and is indicated that in advance constantly calculating transient speed with the maximum difference that lags behind the moment reduces gradually, when being lower than certain value The time, the computer system processor unit is carried out load to this working condition and is increased the weight of to process. At first by the confession that is subjected to computer system control Oil system strengthens mixture strength gradually, simultaneously since rotating speed reduce, air inflow during than high rotating speed more greatly, the hydraulic pressure chamber pressure sensing The analog-to-digital conversion unit of computer system constantly passed to pressure changing by device, is subjected to the impact of above-mentioned two factors, and it is poor to light Value moves closer to and less than predetermined value, at this moment the processing unit control hydraulic control system by the machine of calculation system adds combustion chamber volume Greatly, suitably reduce compression ratio, strengthen gradually the mixture strength coordination with oil supply system, make and light difference and remain on reasonable model In enclosing. When lighting difference greater than predetermined value, the computer system processor unit sends to oil supply system in this process Instruction stops to strengthen gradually the mixture strength action, waits for that combustion chamber volume strengthens, and the reduction of compression ratio is until light difference During greater than predetermined value, continue again to strengthen the mixture strength action. When excessive air coefficient is progressively brought up to from α=1.15-1.1 During α=0.7 left and right sides, the computer system processor unit sends instruction to oil supply system, stops to strengthen gradually the mixture strength action, The simultaneous computer system processing unit also sends instruction to the executing agency of hydraulic control system, makes to rush down pressure electromagnetic valve and keep pressure Unidirectional solenoid valve is closed, and the branch manifold solenoid valve is opened, and hydraulic control system enters hold mode. Because strengthened mixture strength, Output power of internal combustion engine increases. This process is linear with the degree of depth that depresses the foot throttle plate, and its implementation method is to make With computer system correction non-linear partial, eliminate the sensation that the driver " steps on sky ". When measuring, internal-combustion engine rotational speed mensuration system turns to When speed still further reduced, the driver will continue to strengthen the degree of depth that depresses the foot throttle plate, when the degree of depth that depresses the foot throttle plate reaches To 100%, when internal-combustion engine rotational speed is lower than again certain value, output control signal in computer system processor unit is carried out and is started supercharger Working procedure. At first send instruction by the computer system processor unit to the executing agency of hydraulic control system, carry out and reduce compression Than course of action, make it to drop to minimum of a value, suitably increase simultaneously fuel feed, the electromagnetic clutch of pressure charging system is closed On, pressure charging system work begins to the supercharging of air inlet part, strengthens air inflow, and computer system is transferred according to the size of lighting difference The size of joint joint valve opening keeps in the reasonable scope this difference, thereby makes internal combustion engine in optimum state, output Power reaches maximum. At this moment fuel combustion conversion efficiency but decreases. The front topic that makes the pressure charging system action is to use higher octane Value or high self-ignition point fuel. 6, engine load alleviates the work for the treatment of process

To increase the weight of the work for the treatment of process opposite with engine load, when load reduction (for example the gradient is by turning to greatly little or transferring descending to), Internal-combustion engine rotational speed mensuration system measures rotating speed and raises gradually, and the foot throttle pedal returns from depth location, at this moment computer system Processing unit is carried out the load processing of postemphasising to this situation. At first will reduce mixture strength, excess air coefficient is from α=0.7 About progressively be reduced to α=1.15-1.1, make internal combustion engine return to the economic performance duty, the simultaneous computer system processes single Unit also adjusting joint valve opening stops action, therewith together from greatly to little direction action when adapting with foot throttle pedal aperture The computer-chronograph system processing unit sends instruction to the executing agency of hydraulic control system, makes to rush down pressure electromagnetic valve and divide manifold solenoid valve to close Close, force hydraulic oil by keeping the pressure Unidirectional solenoid valve under the pressure that oil pump produces, inflow pipeline flows into hydraulic pressure chamber, compression Ratio regulating system makes compression ratio begin to increase, until computer system is according to lighting difference and hydraulic pressure chamber internal pressure maximum when occurring The size of the difference of carving is in the suitable scope, and hydraulic control system stops to increase compression ratio, begins to enter the maintenance stage. When The driver will be slowed down, and when being reduced to normal power output from peak power output (when referring to supercharging is arranged), foot throttle is stepped on Plate reduces from depth location, and when its degree of depth is reduced to less than 95% the time, computer system processor output control signal makes supercharging The electromagnetic clutch of system is opened, and pressure charging system stops suitably to reduce then fuel feed to the supercharging of air inlet part, makes mixing Gas concentration reduces, and adjusts simultaneously throttle opening, makes it to be suitable for the foot throttle pedal degree of depth, and it is moving to carry out at last the increase compression ratio Make process, make internal combustion engine return to normal economic performance duty. Above-mentioned action also will be by the processing unit control of the machine of calculation system Hydraulic control system suitably increases or the reduction compression ratio, reduces gradually the mixture strength coordination with oil supply system, makes and lights Difference keeps in the reasonable scope. 7, internal combustion engine hydraulic pressure chamber temperature controlled processes

Internal combustion engine is constantly worked, and the heat in the hydraulic pressure chamber constantly accumulation can make the hydraulic oil temperature raise the hydraulic pressure chamber TEMP Device is constantly passed to the computer system processor unit with this physical quantity, treats that this value reaches certain when a bit, and computer system processor is single Unit sends enabling signal to the motor of heat dissipation pump, makes its work. At this moment, high temperature oil is ordered about lower at the pressure of heat dissipation pump, from hydraulic pressure chamber Outlet is flowed back to hydraulic pressure chamber through the catheter pressure of heat abstractor is housed by heat dissipation pump and catheter pressure, realizes that the heat radiation of high temperature oil in the hydraulic pressure chamber follows Ring. When the hydraulic pressure indoor temperature reduces, until be lower than certain value when following, the computer system processor unit sends to the motor of heat dissipation pump and stops Stop signal, heat dissipation pump stop action, and cooling circulates that is stops. So, the temperature of hydraulic oil is controlled within the specific limits. 8, the relation of internal-combustion engine rotational speed and compression ratio

The rotating speed of internal combustion engine, load have very big excursion, and Vehicular internal combustion engine especially is on automobile zero load, full load When slope, descending, during acceleration, the load of starting can be up to minimum, or even changes between " just carrying ", internal combustion engine Rotating speed also can change between the most at a high speed in idling. We know that internal combustion engine could be failed under specified torque and maximum load rotating speed Go out peak power, this moment, its air throttle was on the maximum opening certainly, although air throttle aperture maximum internal combustion engine defeated sometimes It is then not necessarily maximum to go out power, because its rotating speed might not be very high, therefore, is that air throttle is in maximum opening equally, But because the rotating speed difference, the compression ratio of internal combustion engine also has different requirements. When internal combustion engine ran up, the used time of suction stroke very Short, because gas handling system exists vapour lock, when the short time suction stroke finished, the density that participates in the material of burning in the cylinder was wanted Less than the same density of throttle opening when the slow-speed of revolution is spent, like this, in the situation of identical throttle opening, different rotating speeds With it corresponding compression ratio should be arranged, and obviously, the more high raising that should compression ratio is suitable of rotating speed is in the hope of obtaining the height under the high rotating speed Efficient. Because flame transmission speed is only relevant with degree and the mixture strength of the kind of fuel, atomizing behind the mixture combustion, Little with the other factors relation, but the maximum pressure that internal combustion engine requires mixture combustion to produce appears at the top dead centre of compression travel Neighbouring (ordinary circumstance slightly lags behind), so, the maximum pressure in order to guarantee that mixture combustion produces when internal combustion engine runs up Power appears near the top dead centre of compression travel, and (being called the increasing igniting in electric ignition system carries must to make in advance mixture combustion Anterior angle). Therefore, computer system will be revised piston arrives according to the kind of rotating speed, mixture strength and the fuel of internal combustion engine Top dead centre constantly goes out the difference of now with hydraulic pressure chamber internal pressure maximum, namely revises and lights difference. The rotating speed of internal combustion engine more high this Individual difference is also more little, and more low this difference of the rotating speed of internal combustion engine is also more big. Processing unit control hydraulic regulation by computer system System regulates compression ratio under the different rotating speeds according to this time difference. 9, the engine shutdown course of work

Similar to the internal combustion engine deceleration course of work, just the foot throttle plate has been got back to initial position and power-off operation has been arranged. Work as pin Internal combustion engine was decelerated to idling (seeing the deceleration course of work) after the step on the gas plate was got back to initial position, shutdown this moment, computer system Processing unit slightly big position in the time of will making combustion chamber volume remain on than idling operation, then shutdown. Be conducive to like this start next time. Rush down pressure electromagnetic valve, assist and rush down pressure electromagnetic valve and keep the outage of pressure Unidirectional solenoid valve normally closed, divide the manifold solenoid valve outage often to open. If Under the internal combustion engine normal operation, carry out the power-off operation process, then send deceleration work by the machine of calculation processing unit to each relevant portion Process instruction is carried out shutdown again after internal combustion engine is decelerated to idling, the main power source that breaks, computer system is not cut off the power supply, be into Enter low-power consumption " dormancy " or wait state, for starting ready next time. 10, the processing procedure that air throttle is changed among a small circle

When the user drives with regular speed, because the impact of many factors can make the foot throttle plate depress the degree of depth more or less Small variation takes place. For avoiding causing therefrom the magnetic valve frequent movement of hydraulic control system, when its amplitude of variation and variation When speed is worth less than certain, forbid the action of hydraulic pressure chamber and combustion chamber, this need to use the electric heat ignition sheet to assist control. Work as joint Valve opening depresses depth minus hour with the foot throttle plate, and air inflow reduced after suction stroke finished, again because hydraulic pressure chamber and burning Be failure to actuate in the chamber, mixture combustion is postponed constantly, lights difference and reduce, and the pressure sensor in the hydraulic pressure chamber passes this information Give computer system, strengthen electric heat ignition sheet input power by computer system control again, the mean temperature of electric heat ignition sheet is raise, Thereby mixture combustion is shifted to an earlier date constantly, maintain in the zone of reasonableness value until light difference. On the contrary, when throttle opening with When the foot throttle plate depressed degree of depth increasing, air inflow increased after suction stroke finished, and mixture combustion is shifted to an earlier date constantly, and this needs Reduce the mean temperature of electric heat ignition sheet, keep in the reasonable scope until light difference. 11, the not normal processing procedure of hydraulic part work

When the minimum pressure of hydraulic pressure chamber exceeded the scope that computer system controls, the hydraulic pressure chamber pressure sensor was this physical quantity Pass to mould one number conversion part, adjusted by each relevant performance element repetitive control of control after the computer system processor, through adjusting for several times After still do not reach when requiring, partly send alarm signal by the alarm of computer system again, prompting operation person's hydraulic system occur so Barrier is opened simultaneously and is rushed down pressure electromagnetic valve, makes compression ratio get back to minimum of a value, after this no longer controls liquid without the start-up course computer system Press regulating system, still control temperature and the oil supply system work of hydraulic oil, electric heat ignition sheet. This moment still can be by common internal combustion The machine mode works. Also lost efficacy such as temprature control unit and then to be shut down by computer system control. When the minimum pressure of hydraulic pressure chamber not When disconnected rising the and control are inoperative, then shut down by computer system control, send the catastrophe failure alarm signal. 12, security control
