摘要： When the geometric compression ratio of an engine body (2) is set to 13 or more and the engine body operates in a preset high load region, the effective compression ratio of the engine body is set to 12 or more with a difference from the geometric compression ratio being within 2, a gas to be introduced into a combustion chamber (17) is supercharged by a supercharging system (49), fuel is injected at least in a compression stroke by an injector (6), and after the fuel injection is finished, an air-fuel mixture in the combustion chamber is ignited by an ignition plug (25) before the compression top dead center and is thus burned by flame propagation in the engine body, and then the unburned air-fuel mixture is burned by compression ignition.

摘要： A GDCI engine (12) has a piston (16) arranged within a cylinder (14) to provide a combustion chamber (18). According to one embodiment, the GDCI engine (12) operates using a method that includes the steps of supplying a hydrocarbon fuel to the combustion chamber (18) with a research octane number in the range of about 30-65. The hydrocarbon fuel is injected in completely stratified, multiple fuel injections before a start of combustion and supplying a naturally aspirated air charge to the combustion chamber (18).

摘要： An internal combustion engine system includes a spark-ignited internal combustion engine powered by a gaseous fuel. The engine system also includes an air intake in air providing communication with the internal combustion engine. Further, the engine system includes an exhaust system in exhaust gas receiving communication with the internal combustion engine. The exhaust system includes a methane oxidation catalyst through which at least a portion of the exhaust gas flows and an exhaust gas recirculation line in exhaust gas providing communication with the air intake.
