Due to the improvement of structure, the most several methods contributing to combustion in IC engine: admission line and aerofluxus The wall smoothness (especially cylinder head portion) of pipeline, the smoothness of admission line has influence on air inlet temperature Degree and charging efficiency, the smoothness of discharge duct, affect cooling system；Scheme for exhaust gas circulation system (EGR) In waste gas take force cooling be conducive to aeration quantity and exhaust emissions；Diesel oil is mixed appropriate gasoline, can Can promote oil atomizing, speed burning velocity, reduce the growing amount of soot；Gasoline is mixed appropriate bavin Oil, may reduce compression ratio required during gasoline compression ignition.

The design of combination relief piston can not improve the thermal efficiency, can only regulate combustor in limited range The temperature and pressure of interior combustion gas, after being additionally arranged pressure regulation system, range of accommodation and performance obtain significantly Improvement, the burning that approximation is isobaric can be realized in most cases.Along with the development of electronic control injection technology, Analyzing gasoline engine theoretically and can realize compression ignition, be first compression ratio problem, improving compression ratio can To reach the compression ignition condition of gasoline, it is also possible to by preheated air, supercharging, mix the method realizations such as diesel oil Low compression ratio compression ignition gasoline；Next to that the control of combustion process, light type gasoline engine and be usually with spark plug Arcing point be beginning burning-point, by flame propagation in the way of burn, compression ignition type gasoline engine with oil spout starting point is Beginning burning-point, with injection process as combustion process, the beginning burning-point of compression ignition type gasoline engine and combustion process may be with Some difference of diesel engine: stagnant combustion shortening, combustion process are shorter.Currently used cylinder inner high voltage injection system, Being usually and control oil spout with injection pressure and fuel injection pulsewidth, compression ignition type gasoline engine can increase distributive value The function of hole regulation, more adapts to the demand of gasoline engine compression ignition.

The method solving the problem of gasoline compression ignition:

1. control combustion process well, make the maximum temperature and the pressure that produce during burning remain at internal combustion In working range needed for machine；Next to that use the preferable fuel of anti-knock properties, it is also possible to take to mix different substances together diesel oil Method, extend combustion process；

2. use " the combination relief piston " combining pressure regulation system, utilize pressure regulation system Pressure change controls the moving situation of outer piston, it is achieved the regulation control to combustor maximum pressure and temperature System, outer piston quality is the least, and regulation performance is the best, if it is possible to realizes acyclic sealing, can reduce outer work The quality of plug, it would however also be possible to employ the EGR retarded combustion speed of big flow and reduction combustion pressure.

The compression ignition technology of diesel oil is the most highly developed, due to the improvement of structure, removable in diesel oil converts appropriate vapour Oil improves atomization, shortens firing duration, reduces heat transfer loss, improves the thermal efficiency, reduces carbon The discharge of cigarette and the generation of oxynitride.

Following several combustion mode is mainly for the burning of gasoline:

Add " the combination relief piston " of pressure regulation system, in order to reduce heat loss, need to shorten Combustion process, but unsuitable too short, and the range of speeds is similar with gasoline engine；It is applicable to light and compression ignition, with Variable compressive specific binding energy forms variable compressive and lights and variable compressive compression ignition.

Add " the combination relief piston based on elastic noise reduction impact resistance head gasket " of pressure regulation system, Moment of torsion is big, the shortest combustion process, owing to reasons in structure is not suitable for running up, if using The mode of electromagnetic combination, rotating speed can appropriateness improve.Can be used for lighting and compression ignition, tie with pressure-variable compression ratio Conjunction can form variable compressive and light and fractional combustion.

Wherein light, compression ignition, variable compression ratio light and add pressure regulation system combination pressure regulation live Filling in similar, except for the difference that, the burning outbreak period is postponed till outer piston and starts descending crank angle；Secondly, This structure is more suitable for deflagrate, only represents and shortens combustion process, does not represent and run up.

Light, refer to that traditional spark is lighted, compression ratio, late ignition can be improved in right amount, speed burning Speed, shortens combustion process.

Compression ignition, refers to control combustion process and output, class by control injection process and distributive value It is similar to common rail diesel engine.

Variable compressive is lighted, and is according to different operating modes, regulates compression ratio so that in compression stroke top dead center Time, the temperature of gaseous mixture is near but below autoignition temperature, utilizes spark plug to light the mixing close to spontaneous combustion Gas, it is achieved deflagrate；Deflagrate can shorten the process of heat propagation, also can properly increase compression ratio, Be conducive to the raising of the thermal efficiency, but too fast burning influences whether the tune of " combination relief piston " outer piston Joint performance.

Variable compressive compression ignition, is according to different operating modes, regulates compression ratio, make compression travel when top dead centre, The temperature of gaseous mixture is just met for the autoignition conditions of fuel；It is suitable for fuel volatilization vapour in air inlet and compression stroke In the change stage, injecting required fuel and mix with air, the supply of fuel can take multiple spot EFI and in-cylinder direct-jet, Atomizer can be arranged on the plunger of variable compression ratio governor motion by in-cylinder direct-jet；This combustion system class Like homogeneous-charge compression-ignition, being a difference in that, Combustion System and working condition do not have homogeneous-charge compression-ignition so Harshness, next to that omnidistance compression ignition may be realized, without spark-ignition system.

Fractional combustion, refers to add the " based on elastic noise reduction impact resistance head gasket of pressure regulation system Combination relief piston ", in conjunction with variable compression ratio, use two set fuel feed systems, diesel simultaneously High-pressure common rail, a set of gasoline (natural gas) multiple spot EFI or in-cylinder direct-jet；At startup warming-up, suitably During diesel combustion operating mode, the state of compression ratio adjustment to applicable diesel combustion, burning diesel oil；After warming-up, When middle high rotating speed or suitable gasoline combustion work, in induction stroke or compression stroke, it is suitable for gasoline evaporation Evaporation stage, injects required gasoline, utilizes the gaseous mixture that variable compression ratio ends compression, and regulation is to low In but close to the autoignition temperature of gasoline, at appropriate crank angle, a small amount of diesel oil of spray in combustor, Utilize the diesel oil self-ignition point feature less than gasoline to light the gaseous mixture of gasoline and air.

Variable compression ratio, lighting and homogeneous-charge compression-ignition mainly for gasoline engine, and fractional combustion, There is good control action.

The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all in the present invention Spirit and principle within, any modification, equivalent substitution and improvement etc. made, should be included in this Within bright protection domain.
