摘要: The engine is provided with an auxiliary chamber having an auxiliary chamber port with an opening communicated with the combustion chamber. The auxiliary chamber port is arranged to be opened or closed with an auxiliary chamber valve. The timing of closing the auxiliary chamber valve is in between a final stage of compression stroke in which the temperature within the cylinder becomes higher and an initial stage of explosion stroke. On the other hand, the timing of opening the auxiliary chamber valve is in a middle stage of the compression stroke, thereby allowing the mixed fuel cooled in the auxiliary chamber to be replaced with a portion of the mixed fuel in the combustion chamber, thereby lowering the temperature within the cylinder.

摘要: The supercharged internal combustion engine is so adapted as to set the air-fuel ratio to become a lean air-fuel ratio which is leaner than stoichiometric and lean enough to maximize improvements in a rate of consumption of fuel, for example, to the A/F ratio of 16, when the supercharger exists in such a supercharging region as demonstrating its sufficient degree of supercharging capability. When the air-fuel ratio is made lean in the supercharging region, exhaust gases are recirculated into the intake system of the engine, in addition to a mixed fuel. Preferably, the exhaust gases having lower temperatures are recirculated at the time of a high load of the engine in the supercharging region, while the exhaust gases having higher temperatures are recirculated at the time of a low load of the engine therein.

摘要: An internal combustion engine of a spark ignition type is so arranged as to set an air-fuel ratio of a mixed fuel to become substantially stoichiometric in the range of from A/F=13 to A/F=16 at the time of running in a high load region and to recirculate exhaust gases into the intake system. For the internal combustion engine of a natural intake type, the compression ratio is preferably set to 11 or larger; for the internal combustion engine of a supercharging type, the compression ratio is preferably set to 9 or larger. The rate at which the exhaust gases are recirculated is preferably set to be constant or to become larger as the load of the engine becomes larger.

摘要: Disclosed is an exhaust gas recirculation system for an engine having a high compression ratio or with a supercharger. An outside EGR duct connecting the exhaust system to the intake system is provided with a first control valve, which has a second outside EGR duct bypassing the first control valve. The second EGR duct has a second EGR control valve and a cooler. When the engine exists in an extremely low load state, the first and second control valves are closed to inhibit the outside EGR. In the light load state, the first control valve is opened while the second control valve is closed, thereby allowing recirculation of the EGR gases having high temperature and reducing the pumping loss. In the high load state, the first control valve is being closed while opening the second control valve, thereby increasing a recirculation ratio of EGR gases cooled by the cooler and performing both an improvement of anti-knocking performance and a decrease in pumping loss, as well as reducing the heat load of the exhaust system and within the engine.

摘要: An engine-control system is structured in such a way that a timing for closing the intake valve is retarded and the air-fuel ratio is so set as to become a rich air-fuel ratio richer than, for example, the stoichiometric air-fuel ratio, in a region where the load is low. On the other hand, in a region where the load is high, the timing for closing the intake valve is set earlier and the air-fuel ratio is so set as to become a lean air-fuel ratio leaner than, for example, the stoichiometric air-fuel ratio.
