In order to make the PTC systems attempt reach optimum Working, working method, thermal design are very important, effectively avoid making the PTC element to produce electrical breakdown or thermal breakdown.So the fundamental characteristics that at first will understand element especially electric strength, maximum bears voltage, with determine rated operational voltage and with used supply voltage coupling.Clamp and the electrode of element drawn also very important.Except preventing poor electric contact, short circuit and Electric Field Distribution inequality, avoid outside the electrical breakdown, also must prevent to cause the problem that local superheating punctures owing to Mechanical Contact is bad.Reasonably heat dissipation design is an effective way of giving full play to the element heating ability.The structure of PTC heater element, type, power, performance, shape and size and Curie temperature preferably with the specification of heat vapourizer, size, pattern, shape, temperature required, construct or it combines and is complementary.Can coordinate the relation between heat vapourizer and surface temperature and the heating power during design on demand.Can take a plurality of elements to electrically connect or with other element mixing connecting mode.The most handy parallel connection need not be connected between the PTC ceramic plate.The PTC element belongs to non-fine finishing series products, and conformity is poor, the element of different batches even same batch process, and its every performance also is difficult to accomplish unanimity.When series connection is used, the temperature rise speed difference of each element, resistance is also different, and the pressure drop distribution that drops on each element changes rapidly, and produces vicious circle.Pressure drop is big more, and temperature is high more, and this element may puncture more, in case chain the going on of puncture meeting taken place.So series connection is used must be very prudent, strictness to select element, otherwise, wish to use the purpose that reaches ideal effect by series connection, be difficult to realize.The in parallel use is though there is the shortcoming situation far better.With the use in parallel of a plurality of PTC elements, in certain limit, can increase the working power of system, but the heating power of a plurality of element parallel connections is not to be the summation of discrete component heating power, in fact often much smaller.Total inrush current neither the discrete component inrush current superposition, generally also smaller, when using less element, the inrush current of monolithic is desirable big, inrush current is big, temperature rise is rapid.But when using than multicomponent, the inrush current of discrete component can not select too greatly.

Scribble adhesive type far infrared coating at all hot evaporating faces that comprise heat-removal bar, mixed gas passage face and heat vapourizer body bottom surface on positive and its face of heat vapourizer upper and lower cover inner face, heat vapourizer body.In heat vapourizer, also have and the Carburetor air air inflow of institute's adapted, the motor car engine discharge capacity of institute's adapted, best hot evaporating face and the hot vaporizing chamber that is complementary with oil or other available combustion liquid measure, power character etc.Outer side surface at this heat vapourizer; also be provided with the power-line terminal and the thermal transmitter outer terminal of PTC ceramic heating plate, join in order to the instrument that can monitor with the generator power supply of adapted and storage battery, at operator cabin, tutorial light, buzzer, electric switch, overheated, overcurrent, decompression, under-voltage and short current protection system etc.Heat vapourizer loam cake inlet hole be connected screw and throttle body air outlet hole and be connected the screw coupling, connect, connect admittedly mutually with bolt and throttle body, use thermal baffle and heat insulation sealing gasket to seal with air tight degree of being therebetween.The mixed gas air outlet hole of heat vapourizer lower cover and the inlet hole that is connected screw and engine air inlet tube be connected the screw coupling, connect, be encased inside the heat conduction sealing gasket therebetween, with the east wind EQ140 of bolt tightening in institute's adapted---on the 1 type automobile engine intake tube, make it air tight.Heat vapourizer loam cake, body, lower cover tighten up with 4 long screws connections, and each junction plane is locating pin formula location, plane combination, have the sealing of heat conduction sealing gasket air tight therebetween.Heat vapourizer thermal source inlet, outlet inipple pipe is connected with repacking engine exhaust pipe well.The thermal source air inlet valve of being furnished with manual ladder operating stem control, air inlet constant temperature system device, air-strainer stops up alarm system, the two air-strainer air inlet strengthening system devices of air conducting type, the fuel evaporation control system device, the pinking limiter, backfireproof automatic safety system and device, three-way catalytic converter, the exhaust gas recycling system device, the secondary air supply device, the PCV system device, generator power supply and the storage battery etc. of heating and heat-insulating device is arranged.Simultaneously, motor is all done corresponding improvement and is connected with the car all involved.The prompting of the instrument that when engine operation, can monitor at operator cabin, tutorial light, buzzer by driver's foundation, handle manual ladder operating stem thermal source control valve, regulation and control import in the heat vapourizer thermal source runner and are used through the engine exhaust hot gas flow of cooling, step-down and the processing of flow velocity homogenization and the temperature automatically controlled electric heating PTC ceramic plate of electric switch control, hot vapourizing temperature are controlled at about 170 ℃ (reach this desirable matter by the practicability debugging).So far, accused and finished according to the wherein a kind of fuel-oil heat vaporization oil feeding method of the present invention's proposition and improvement, making, the installation of equipment high efficiency oil saving and pollution reducing vaporizer.

When piloting engine work, open heat vapourizer electric heating part power supply earlier, connect heating circuit, electric current promptly enters the PTC ceramic plate through lead, gets back to storage battery again behind the heat vapourizer bonding.Electric current transfers electric energy to heat energy heat hot vaporizer by the PTC ceramic plate.After treating that temperature indicating device and buzzer and tutorial light indicate hot evaporating face temperature to be raised to 170 ℃ of predetermined temperatures, can open starter switch pilot engine (or be designed to reach temperature, automatically starting also can).When starter motor drives engine rotation, because the getter action of aspirating stroke, just form certain low pressure (vacuum) at the carburetor throat place, under the effect of this low pressure, air (normally in service is about 40 ℃ of constant temperature) just flows into Carburetor through air-strainer.Because of channel cross-section diminishes, air velocity increases when air flows through trunnion, and pressure just further reduces (fallen and strengthened the pressure that causes by flow velocity and fall the superposition of the two by the air-breathing pressure that causes), forms certain pressure difference with atmosphere.The indoor fuel oil of carburettor float this moment is sprayed by spout through metering-orifice under this action of pressure, and is dispersed into many large and small vaporific particles that do not wait, the atomizing of promptly so-called traditional Carburetor intermediate fuel oil under the bump of high-speed air flow.The fuel oil of these atomizings owing to the air stream with high speed contacts, and because the degree of vacuum of trunnion and mixing chamber is impelled the most volatile part of fuel oil, at first from elaioleucite surface start vaporizer, causes the fraction fuel gasification at carburetor throat and mixing chamber place.When these most of atomizings, when the fuel oil of fraction vaporization and AIR MIXTURES are flowed through heat vapourizer with can be with a lot of far infrared radiation line that should vaporific fuel oil transient heat vaporization and the very big hot evaporating face (front of 257 square centimeters in the round flat box of spill at the bottom of the round pan in the middle part of heat vapourizer body, its surface area on its face of gathering is 1587 square centimeters a heat-removal bar, 478 square centimeters mixed gas passage face, 257 square centimeters of positive bottom surfaces, total heat dispersing surface of totally 2579 square centimeters) after the contact, promptly be heated strong vaporization and air mixing and form deflagrating mixture, and enter engine intake manifold and cylinder by mixed gas passage.Because the rising of temperature in the compression stroke, simultaneously again because the eddy current that air inlet mixed flow and eddy current and aspirating stroke and compression stroke cause, further impel air and the fuel oil homogeneous that gasified mixes the homogeneous deflagrating mixture that forms best ingredients in cylinder.Deflagrating mixture is compressed in compression stroke, burns immediately and expands and promote piston and make engine start work through plug ignition closing on the compression stroke end.

When motor starts under cryogenic conditions, because fuel-viscosity variation increases and starting speed is low, what be difficult for being dispelled, fall from Carburetor by aerodynamic force is that supreme one the circulate starting difficulty factors such as cold conditions of residual high-temp waste gas and engine block are also not serious in oil droplet, the cylinder.The fuel oil oil droplet that fallen by Carburetor this moment is dropped on the hot evaporating face of heat vapourizer of heating, promptly diffuses to form thin oil film rapidly.Carry out nucleate boiling after this skim fuel oil is heated immediately, meanwhile produce a large amount of fuel vapors.Fuel vapor just forms deflagrating mixture with the air that enters once mixing.Deflagrating mixture is inhaled into cylinder, because the effect of the eddy current that air inlet mixed flow and eddy current and aspirating stroke and compression stroke are caused in cylinder has formed high-quality homogeneous deflagrating mixture, is compressed in compression stroke, is closing on the compression stroke end once igniting, burning makes engine start immediately.After the engine start, heat vapourizer still works on, and produces a large amount of fuel vapors, to enter steady running with keeping engine reliable.At this moment motor has promptly been finished whole starting process, starts successfully.

During engine cold starting,, often to close the chock plate of Carburetor for supply adds rich mixture.When motor was intact quick-fried, rotating speed increased sharply, because the increase of airspeed and intake depression, the amount of fuel of carburetor jet ejection increases, make the mixed gas overrich, must corresponding immediately supply weak mixture, otherwise can extinguish because of the mixed gas overrich causes motor.The intact quick-fried device of EQH105 type Carburetor, utilized the sucking action of the higher degree of vacuum of quick-fried moment formation to the vacuum diaphragm, in time chock plate is drawn back certain angle, improve air inflow, guarantee that effectively motor does not extinguish and reduced HC, CO effluent concentration.But must correctly adjust, when making diaphragm be in the attracted position, chock plate aperture R ≈ 4mm.The chock plate aperture can not be excessive or too small when intact quick-fried.When too small, the mixed gas after the meeting enriching is intact quick-fried; When excessive, can make mixed gas become rare, easily make engine speed not steady, even extinguish.

Behind the engine cold starting, because the lubricating oil viscosity height, reason such as interior surface friction drag is big, normal idling throttle opening is difficult to supply with keeps the required air-fuel mixture amount of engine idling operation.Running is slick and sly, steadily and shorten warm-up period when guaranteeing cold car idling, utilize the fast-idle speed pull bar of handling interlock with chock plate, by the fast-idle speed rocking arm, make closure along with drawing of chock plate closed, on the basis of normal idling aperture, open big certain angle again, thereby strengthen the air inflow of warming-up, make rotating speed be higher than normal idling.Fast-idle speed not only helps shortening warm-up period, and guarantees that effectively engine idling operation is steady, avoids driver's " Hong throttle " inadequately, and is also beneficial to reducing fuel consume and HC effluent concentration.

After engine start and thermal source air inlet valve normally in service, manual or temperature automatically controlled, just regulation and control import hot gas flow heat hot vaporizer in the heat vapourizer thermal source runner effectively; The heat that the PTC system can be consumed according to the thermal efficiency and the heat vaporization of thermal source flow, automatically increase and decrease power, carry out thermal compensation, when cooperating the work of maintaining heat vaporizer and the thermal equilibrium when zero load, to guarantee the operating temperature of heat vapourizer, constantly produce enough fuel vapors, guarantee the needs of the various working characteristicses of motor the mixed gas quality and quantity.As meet the heat vapourizer temperature by chance above the upper limit or lower limit, just it is temperature transducer can be transferred to signal the emergency alarm starting buzzer and the warning that sends out a warning, normal so that the driver in time regulates and control to recover.

When automobile is in when sliding (deceleration is slided, quickened to slide, downhill running), motor does not need fuel feeding, at this moment carburetor throttle is in idle position, but, motor does passive running up because being driven by automobile, general Carburetor still can be continuously from idler nozzle ejection fuel oil, and this and situation claim forced idling.Fuel consumption and idling operation during forced idling are about the same, according to the statistics made by the departments concerned, account for 8 of whole oil consumption---and 10%.Forced idling mode comprises downhill running; Utilize the braking of motor assisted deceleration when lower long slope or abrupt slope consciously; Automobile is when flat pavement running, high idle speed operating mode when gear shift in blocked operation method of employing acceleration---sliding---acceleration and conventional driving the, deceleration and decelerating mode etc., under these conditions, all exist engine speed to be higher than idling speed and don't need the situation of fuel feeding.According to the situation of Chinese highway, when automobile travelled in the mountain area, forced idling mode accounted for 40%, travelled and account for about 15% in the Plain.If under forced idling, stop fuel feeding, with regard to the energy fuel saving, and help guaranteeing traffic safety, reduce component wear.EQH105 type Carburetor ISC-E cutting device (fuel-saving machine) is exactly when automobile carries out forced idling mode, utilizes electronic control, to stop up the Carburetor idling outlet orifice or to block idle fuel way, to stop the gasoline-saving device of fuel feeding.When the forced idling rotating speed is higher, intake depression is very high, because of influences such as air fuel ratio, ignition timing, (at this moment trunnion degree of vacuum is low for the fuel oil that the Carburetor idling is supplied with, the not oil spout of main jet pipe) is difficult to burning, not only wasted fuel oil, the HC effluent concentration is sharply increased, and unburned oil also can wash away cylinder wall lubrication oil film increase engine scuffing.For preventing automobile when the change working, the phenomenon such as flame-out that causes because of the idling fuel feeding is untimely, the ISC-E cutting device not only blocks the idling fuel feeding automatically when forced idling mode, and can recover the idling fuel feeding automatically.General common rotating speed is fixed on is higher than idling speed 300---and 400 rev/mins.EQH105 type Carburetor idling cutting device is 850 rev/mins.When closure at idle position, engine speed is higher than 850 rev/mins or when closing ignition switch, solenoid valve just can block the idling fuel feeding.In case and rotating speed is lower than 850 rev/mins, will recover the idling fuel feeding automatically.The ISC-E fuel-saving machine by block and recover the fuel delivery of forced idling mode in good time, has reached the purpose that part is energy-conservation, reduce pollution like this.Other auxiliary fuel-economizing simultaneously, Exhaust gas purifying device have also reduced part oil consumption and exhaust pollution (details because of belonging to prior art, is given unnecessary details no longer one by one) effectively.

Because heat vaporization and the optimized crux effect of ingredients, Carburetor atomizing fuel feeding traditional, that fall behind is become advanced heat vaporization fuel feeding, make mixed gas produce the leap of quality and quantity, from quality with quantitatively all reached the optimum state---become the homogeneous deflagrating mixture of best ingredients, in cylinder, reach the perfect boundary of perfect combustion, reduced oil consumption significantly and reduced exhaust pollution.Owing to installed intact quick-fried device, fast-idle speed, ISC-E fuel-saving machine and other fuel-economizing and Exhaust gas purifying device, part fuel consume and exhaust pollution have also been reduced effectively again.Again because be provided with the system and device safe in utilization that the heat vapourizer temperature shows and temperature over-range sound, light warning device and protective gear and AE (acoustic emission) sensor etc. detect automatically and warning system constitutes; so driver or tractor driver are had gained some understanding at any time to heat vapourizer and engine condition, also just improved reliability and Security greatly.Fact proved: fuel-oil heat vaporization oil feeding method and equipment high efficiency oil saving and pollution reducing vaporizer had both kept existing Carburetor, can satisfy the advantage of the various working characteristicses of motor substantially to the requirement of inflammable mixture concentration and quantity, solve again and remedied that its atomizing is not good, oil particles is big and ingredients is coarse, bigger than normal, deflagrating mixture can not burn in cylinder completely, deficiency such as oil consumption height, exhaust pollution are serious accomplishes to maximize favourable factors and minimize unfavourable ones, have complementary advantages.Can be described as from crux aspect and many-sided the improvement and perfect technology and usability, is the best home to return to of traditional Carburetor in fact, the most perfect form.So the oil saving and pollution reducing effect is surprising especially.Show through test of many times: under the prerequisite that satisfies main usability of motor and assurance engine power performance, compare fuel-economizing up to 45.2 with traditional Carburetor---61.1%, reduce exhaust pollution 80---90%; Control the fuel-economizing of fuel injection system device up to 35.2 than traditional computer---51.3%, reduce exhaust pollution 40---50%.Reached under the prerequisite that satisfies main usability of motor and assurance engine power performance, reduced oil consumption significantly, to greatest extent, reduced exhaust pollution, also can guarantee motor starting smoothly under cryogenic conditions, realized the ideal effect of round-the-clock proper functioning.
