Description
(1) technical field
The present invention relates to a kind of internal-combustion engine, especially a kind of external-compression rotary piston engine.
(2) background technique
Internal-combustion engine mainly contains three types at present: 1) reciprocating piston type four stroke engine
Through 100 years of development, the technology of reciprocating piston type four stroke engine is quite ripe, and has set up complete, modern production system.
The working procedure of reciprocating piston type four stroke engine is: by the to-and-fro motion of piston, realize air-breathing, compression, outburst (expand, acting) and these four working strokes of exhaust, thereby the thermal power transfer of finishing fuel becomes mechanical energy.For four stroke engine, bent axle whenever takes two turns and does merit one time, and therefore, its specific power and power per liter are lower than two stroke engine and Wankel RC configuration.In addition, the torque characteristics of reciprocating piston type four stroke engine is unfavorable, does not have the characteristic of low-speed big.Require from the ride characteristic of automobile, wish when engine speed reduces, still can export higher moment of torsion,, overcome running resistance and continue to travel so that make automobile under the situation of not interrupting power.This specific character of motor can directly have influence on the power character and the fuel economy of automobile.Also have, conventional engine is not the desirable mechanics mechanism that forms moment.For conventional engine, the downward thrust of piston is broken down into perpendicular to the cross component force of cylinder wall with along the axial thrust load of connecting rod centerline direction; On rod journal, the latter is broken down into again along the radial component of crank direction with perpendicular to the circumferential component of crank; This circumferential component is the key element that produces engine output torque, and circumferentially the size of component changes with the variation of crank position, thereby has influence on the value and the characteristic of engine output torque.In addition, when the gas pressure in the cylinder is maximum (during outburst), when just being the circumferential component minimum of crank; And the circumferential component of crank is when maximum, just is again the state that pressure in the cylinder is in middle pressure.This formation to moment is unfavorable.This unfavorable mechanics mechanism produces very big negative effect to the mechanical efficiency and the torque characteristics of motor, and finally has influence on the power character and the fuel economy of automobile.2) reciprocating piston type two stroke engine
The reciprocating piston type two stroke engine bent axle of conventional version turns around and does merit one time.Its advantage is: specific power is big, the power per liter height, and simple in structure, component are few, and are in light weight.But compare with four stroke engine, there is significant disadvantages in two stroke engine, as: volumetric efficiency is not high, and mean effective pressure is low, and idling performance is poor; Compression ratio is less, and compression end of a period pressure is not high, and pressure of explosion is low, and total efficiency is low, and fuel economy is poor, and consumption of lubricating oil is many, and the HC harmful gas of discharge is higher, or the like.These shortcomings also are mainly used on the motorcycle of little air displacement the reciprocating piston type two stroke engine of conventional version at present.3) wankel rotary engine
The wankel rotary engine is compared with the reciprocating piston type four stroke engine, has four working strokes equally, and its main shaft whenever turns around, and motor is done merit three times, thereby specific power is big, power per liter is high, and torque characteristics is also better.Compare with the reciprocating piston type two stroke engine, have advantages such as simple in structure, in light weight, that volume is little equally.Its significant drawback is: the linear velocity of triangle piston tip is higher more than 50% than the linear velocity of conventional engine piston, causes the quick wearing and tearing of Stamping Steel Ribbon and cylinder body; Stamping Steel Ribbon is done trochoidal curve running with high speed, and periodically, act on the casing wall repeatedly, makes casing wall very easily form the chatter ripple, directly influences the working life of rotary piston machine.In addition, its fuel economy is also relatively poor.Therefore, have only the only a few vehicle to adorn at present and use Wankel RC configuration.
(3) summary of the invention
The present invention is directed to existing above-mentioned deficiency of available engine and shortcoming, provide that a kind of specific power is big, power per liter is high, torque characteristics is good, output torque is big, simple in structure, cost is low, the life-span is long, serial modification convenient, further optimize the external-compression rotary piston engine of car transmissions structure and parameter.
External-compression rotary piston engine of the present invention mainly is made up of coaxial core type rotary piston machine, air compressor and pressure regulator three parts.
Different with the reciprocating piston type four stroke engine, feature of the present invention be with air inlet, compress, catch fire the outburst and these four working strokes of exhaust in two mechanisms, carry out respectively: carry out the air inlet and the compression of air by independent air compressor, realize four-stroke preceding two strokes; By concentric, the rotary piston machine that do not have a compression function realize catching fire outburst and exhaust, finish four-stroke latter two stroke, that is: concentric, do not have the rotary piston machine of compression function, by means of being arranged on the air that its air outside compressor is compressed, after the fuel mix that enters the high atomisation in the rotary piston machine air flue simultaneously, enter burning in the firing chamber of rotary piston machine, outburst jointly, promote rotor rotation, realize the transformation of energy of fuel.Owing to adopt air compressor pressurized air, make the present invention from realizing the two-stroke process in essence, thereby have high specific power and power per liter, and avoided the shortcoming of traditional two stroke engine.
Air compressor among the present invention adopts reciprocating piston type, rotary type (rolling-piston-type, rotary-piston type, rotary vane type etc.) compressor.Adopt rotary air compressor, in engine operation process, do not have to-and-fro motion, therefore reduce the vibration of motor significantly.
Pressure regulator among the present invention is a tank container that has pressure regulator valve, and it is between air compressor and rotary piston machine.It is the pressure regulator of rotary piston machine required air, also is balace weight, the buffer that is compressed air condition; Pressure regulator can store a considerable amount of high-pressure airs.Under the cruising operating mode, high-pressure air enters rotary piston machine through pressure regulator, uses for fuel combustion; When motor causes that because of the automobile resistance increases rotating speed reduces, " residue " pressurized gas that pressure regulator is stored are subjected to the control of electronic equipment, and the high-pressure air of some is provided to rotary piston machine, and the supply that strengthens fuel at this moment, thereby overcome of short duration motor unstable period.Pressure regulator produces great influence to the low-speed dynamic of rotary piston machine.
Different with Wankel RC configuration, the present invention adopts coaxial core type rotary piston machine.So-called " concentric " is exactly that the gyration center line of rotor and the center line of housing bore coincide, and rotor rotates in the center hole of housing, and therefore, it does not have compression function.
Coaxial core type rotary piston machine among the present invention mainly is made up of housing, rotor and component that some are necessary.2-4 firing chamber is set on rotary piston machine.The firing chamber is formed jointly by the crescent shape groove on the rotor periphery, groove, swing type reaction plate and rotary type valve on the housing.During engine start, drive rotor rotation by starter motor, when the leading peak face of rotor crescent-shaped slot forwarded to the corresponding position of housing groove, reaction plate descended rapidly from initial position, come to the lower back portion of housing groove, and touch with rotor crescent shaped groove bottom connection.At this moment, under the drive of timing gear, the laterostigmatal rectangular hole of rotary type overlaps with rectangular hole on the housing, so, be compressed to by air compressor and enter in the firing chamber after high-pressure air and oil nozzle by computer control in the pressure regulator sprays into the fuel mix of the high atomisation in the air flue.When rotor was rotated further, under timing gear drove, the rotary type valve was crossed the rectangular hole on the housing rapidly, formed the firing chamber of sealing.At this moment, the spark plug that is positioned on the housing begins igniting, so inflammable mixture catches fire, breaks out, pressurized gas affact on the leading peak face of rotor crescent-shaped slot, promote rotor rotation.When pressurized gas expand into to a certain degree, the leading peak face of epitrochanterian crescent-shaped slot reached the position that is located at the relief opening on the housing, under the effect of tail surface behind the rotor crescent-shaped slot, the waste gas of the overwhelming majority was discharged in the atmosphere, so finish a work cycle.In a cyclic process, two firing chambers are broken out four times altogether; Three firing chambers are then broken out 9 times.The firing chamber of rotary piston machine is compact more a lot of than the reciprocating piston type four stroke engine firing chamber of same row tolerance, and fuel combustion gets more abundant, causes the minimizing of harmful components in the raising of fuel economy and the waste gas.
The rotor of coaxial core type rotary piston machine has constant action radius, and therefore, under the effect of pressure of explosion, rotary piston machine can produce very large output torque.Coaxial core type rotary piston machine is the desirable mechanics mechanism that produces moment, and it improves the mechanical efficiency of motor significantly, and changes the torque characteristics of motor.Result of calculation shows that output torque can reach more than 10 times of same row tolerance reciprocating piston four stroke engine, and this can cause the great change of automotive transmission and ransaxle structure and parameter undoubtedly.
The air displacement of air compressor of the present invention only is half of identical output power reciprocating piston type four stroke engine air displacement, promptly four cylinders become two cylinders, six cylinders become three cylinders, these characteristics not only help the general arrangement of automobile, and the serial modification of motor is also with very convenient.
On the housing of rotary piston machine, air throttle is installed,, is regulated the size of air inflow with this by the aperture that the driver controls it.
Oil nozzle by computer control is installed on the housing of rotary piston machine, and it sprays an amount of fuel according to the aperture and the vehicle operational mode of air throttle to air flue.
Necessary sealing, cooling and lubricating fitting are set on rotary piston machine.
The present invention can also make the external-compression rotary piston diesel engine, and its structural system and external-compression rotary piston petrol engine are basic identical.Petrol engine is installed the position of spark plug on the rotary piston machine housing, and the diesel oil oil nozzle is installed.In order to realize the Diesel process, the diesel rotor facility have the structural feature of ordinary diesel oil machine, and can reach the desired compression end of a period of diesel oil spontaneous combustion pressure and compression finishing temperature; All component of diesel rotor machine all reach the requirement of diesel engine condition; Oil supply system is also adjusted its fuel feeding cycle and fuel injection quantity according to the requirement of external-compression rotary piston diesel engine.
