摘要： PURPOSE:To promote combustion by extracting compressed air in a combustion chamber from an extraction valve in the compression stroke of an engine, compressing the extracted air with a high pressure gas generator and returning it to the combustion chamber after adjusting it to a proper temperature with a heat exchanger. CONSTITUTION:A compressed air indenting port 13 and extraction port 14 separately from intake and exhaust ports are respectively opened to a combustion chamber 9 of an engine 1 and provided with a high pressure gas valve 4 and extraction valve 5 respectively. The extraction port 14 is connected to a pump chamber 10 of a high pressure gas generator 2 which in turn is connected to a pressurized air indenting port 13 through a heat exchanger 3 or the like. Compressed air extracted from the extraction valve 5 in the compression stroke of engine 1 is further compressed in said generator 2, adjusted to a proper temperature by the heat exchanger 3 and then returned from said high pressure gas valve 4 to the combustion chamber 9. Thus, turbulence is generated in the combustion chamber 9 while oxygen is replenished to promote combustion.

摘要： PURPOSE:To decrease nitrogen oxide, by injecting preset quantity of fuel during preset stroke of an internal combustion engine, and after that, injecting preset quantity of fuel moreover, for reducing nitrogen oxide generated by combustion, through thermal decomposition of fuel. CONSTITUTION:An internal combustion engine, such as a Diesel engine E1 is formed with a recession 4 on a piston 3, and this recession 4, a cylinder head 1 and a cylinder block 7 from a main combustion chamber 5. This main combustion chamber 5 is connected to a whirl chamber 2, through a connecting hole 6. In this case, the Diesel engine E1 is formed with a pump 10 for re-injection besides a pump 9 for main injection, to perform re-injection of very small quantity of fuel, after main injection by an injection nozzle 8 is finished, and these pumps 9, 10 are connected to a pump drive shaft 12. With this device, nitrogen oxide generated by combustion, is reduced by thermal decomposition of fuel, and consequently, nitrogen oxide is decreased.

摘要： PURPOSE:To improve a combustion property, by constructing a combustion chamber of a main chamber and a small chamber with a small volume communicating with the main chamber through an orifice and ejecting combustion gas produced in the small chamber into the main chamber through the orifice. CONSTITUTION:A combustion chamber formed between the lower surface 16 of the cylinder head 15 and the top portion 17 of the piston 14 of a 2-cycle crankcase compression type diesel engine 11 serves as a main chamber 18. The cylinder head 15 provided with a recessed portion 19 formed to a shape of a substantially toroidal curve is communicated with the main chamber 18 through a substantially taper-shaped opening 21. Further, a spherical small chamber 31 is formed in the cylinder head 15 and the small chamber 31 is communicated with the recessed portion 19 through an orifice 32 disposed eccentrically from the center of the recessed portion 19. Combustion is effected in the main chamber 18 for increasing the pressure in the small chamber 31 to make combustion in the chamber 31, whereby a high speed flow is produced in the main chamber 18.

摘要： PURPOSE:To ensure the combustion of volatile fuel oil with low cetane numbers without degrading fuel consumption and output by multiplexing an ignition means igniting depending on the opening of a throttle valve adapted to be closed in adjustment when misfire is detected by an ignition sensor. CONSTITUTION:In a controller 22, the operating condition of an internal combustion engine for the time when misfire is detected by an ignition sensor 30, is detected by both engine speed and the opening of an accelerator transmitted from an engine speed sensor 27 and an accelerator sensor 28. And a target opening for throttling a suction throttle valve 11 and a duty ratio are computed to meet the operating condition. Based on these computed values, a pulse control is provided in energizing a VSV 19 for opening a negative pressure passage 21 between a vacuum pump 20 and a negative pressure chamber 17 so as to close the opening of the suction throttle valve 11 in adjustment. And the number of igniting by an ignition means 7 is computed simultaneously depending on the operating condition of the internal combustion engine 31 for outputting the number of igniting to an igniting number controller 26 so as to make the ignition means 7 multiplex the ignition.
