摘要： When the geometric compression ratio of an engine body is set to 13:1 or more and the engine body operates in a preset high load region, the effective compression ratio of the engine body is set to 12:1 or more with a difference from the geometric compression ratio being within 2, a gas to be introduced into a combustion chamber is supercharged by a supercharging system, fuel is injected at least in a compression stroke by an injector, and after the fuel injection is finished, an air-fuel mixture in the combustion chamber is ignited by an ignition device 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 gasoline compression ignition engine, a vehicle and a method of operating a gasoline compression ignition engine. An inlet air management system includes a membrane-based separator and an exhaust gas recirculation flowpath that cooperate to deliver a nitrogen enriched air stream to the engine to help reduce exhaust gas emissions. The separator segregates the incoming air into the nitrogen enriched air stream as well as an oxygen enriched air stream such that the latter can be used for various engine load conditions, as well as for supplemental air for a cabin or related passenger compartment within a vehicle that is powered by the engine. Significantly, during an increase in engine load not associated with the cold start and warm-up conditions, the nitrogen enriched air supply that is used for the exhaust gas emissions reduction is provided at least partially by the nitrogen enriched air stream from the separator, as well as increasingly by the nitrogen enriched combustion product stream from the exhaust gas recirculation flowpath.

摘要： An opposed-piston engine system equipped for full hybrid compressed-air/combustion includes capacity for storing air compressed by the engine during a combustion mode of operation. The hybrid opposed-piston engine system includes a control mechanization for operating the opposed-piston engine in a combustion mode by provision of fuel, in a compressed-air mode by provision of stored compressed air, and in a combustion mode supplemented by provision of stored compressed air. A method of operating a hybrid vehicle equipped with an opposed-piston engine includes storing air compressed by the engine during a combustion mode of operation and operating in the vehicle a compressed-air mode by provision of stored compressed air.

摘要： An engine system is provided, which includes a main combustion chamber, a subchamber, an injector that injects fuel into the main combustion chamber, a main spark plug that ignites a mixture gas inside the main combustion chamber, and a subspark plug that ignites the mixture gas inside the subchamber, an throttle valve, and a control device. In a first range, compression self-ignition combustion of the mixture gas inside the main combustion chamber is performed. In a second range, flame propagation combustion is performed while setting an air-fuel ratio of the mixture gas lower than that in the first range. Immediately after the transition from the first range to the second range, only the subignition is performed, or the subignition and the main ignition are performed while setting a timing of the main ignition to a timing same as or retarded from the subignition.
