摘要： A high thermal efficiency lean-burn spark-ignition two or four stroke engine operable unthrottled suitable for vehicles using gasoline. It uses an indirect combustion chamber and a transfer orifice with shaping of the combustion chamber to produce a jet of air moving in helical swirl motion around the chamber during the compression stroke. Fuel is injected into the chamber aimed into the air jet to assist rapid vaporisation. The position and orientation of the fuel injector ensures that fuel arrives near the spark plug even under idling conditions and the helical swirl flow ensures the stratification of the ignitable mixture formed near the plug. The compression ratio of the engine can also be variable and a second fuel injector can be provided.

摘要： The invention discloses a method of operating an internal combustion engine, of the Merritt type. The Merritt type engine has a combustion chamber (5, figure 1) separate from the cylinder, in which the chamber receives gas during the compression stroke through a transfer orifice. The transfer orifice provides tangential velocity component to the gas, there is also a means to impart axial velocity component to the gas, which produce a swirling air flow within the chamber. The combustion chamber includes an injection and ignition means. The method comprises delivery of fuel from the injector into a bump clearance volume above the piston, after ignition and/or after the piston commences its expansion stroke, such as a post injection while the piston is at or after top dead centre. The method may also throttle the air inlet means by partially restricting the air inlet means. The injector may be controlled to have multiple injection profiles. The methods allow exhaust emission to be controlled, by reducing the amount of nitrogen oxides (NOx) in the exhaust, and increase the temperature of the exhaust to assist a catalytic convert. It also allows for control over peak pressures and increased power density within the engine.

摘要： An internal combustion engine includes: a main combustion chamber (10); an intake port (30) connected to the main combustion chamber; an exhaust port (40) connected to the main combustion chamber; a sub-chamber (50); and a spark plug (60) in the sub-chamber. The sub-chamber is provided between the intake opening portion and the exhaust opening portion and connected to the main combustion chamber through a plurality of communication holes. The communication holes include a first communication hole (51i) provided on the intake opening portion side, and a second communication hole (51e) provided on the exhaust opening portion side. The first communication hole (51i) is closer to the piston than the second communication hole (51e) is. The first communication hole (51i) is inclined to be closer to the piston as the first communication hole (51i) is positioned toward the inside from the outside of the sub-chamber (50).

摘要： In certain embodiments with large size prechambers and/or with prechambers that have large spark-gap electrode assemblies, a poor scavenge of the crevice volume may cause deterioration of the preignition margin, which then may limit the power rating of the engine, may cause the flow velocity field of the fuel-air mixture to be excessively uneven and may result in the deterioration of the misfire limit. One or more auxiliary scavenging ports may allow admission of fuel rich mixture to the crevice volume, thereby cooling the residual gases and preventing occurrence of preignition. More organized and powerful flow velocity fields may be obtained in the spark-gap electrode assembly region. This condition may result in a significant extension of the flammability limit and may significantly improve the combustion efficiency of the prechamber. Passive prechambers using the active scavenge concept may increase the engine power output and reduce the emission of pollutants from engine combustion.

摘要： In an internal combustion engine of the auxiliary vortex combustion chamber type, the volume of the auxiliary combustion chamber and a connection hole is about 65% to 95% of the total combustion chamber volume when the piston is at top dead center. The auxiliary combustion chamber extends over a major part of the cross-section of the cylinder. Thus, it is possible to obtain a higher output without increasing the size of the engine.
