摘要： A direct fuel injection engine basically comprises a combustion chamber, a piston with a cavity, a fuel injection valve, a spark plug and a control unit. The fuel injection valve is configured and arranged to directly inject a fuel stream into the combustion chamber in a substantially constant hollow circular cone shape in a stratified combustion region. The control unit is configured to ignite a first air-fuel mixture formed directly after the fuel stream is injected and prior to a majority of the fuel stream striking the cavity when the direct fuel injection engine is operating in a low-load stratified combustion region, and to ignite a second air-fuel mixture formed after a majority of the fuel stream is guided by the cavity toward an upper portion of the combustion chamber above the cavity when the direct fuel injection engine is operating in a high-load stratified combustion region.

摘要： An internal combustion engine includes neighboring main and auxiliary combustion chambers that are separated by a partition wall including a communicating passage. Ignition of an air/fuel mixture in the auxiliary combustion chamber produces a fuel torch that is jetted into an air/fuel mixture in the main combustion chamber. Under a predetermined operation condition, timing for opening an intake valve is retarded relative to both the timing for closing an exhaust valve and the timing for top dead center of a piston on an exhaust stroke. By retarding the timing for opening the intake valve, residual gas in the auxiliary combustion that is left over from a previous cycle can be reduced.

摘要： A reforming catalyst (6) induces an isomerization reforming reaction and a decomposition reforming reaction of a gasoline fuel. Injectors (27, 33, 35, 36) supply an isomerized fuel generated by the isomerization reforming reaction and a decomposed fuel generated by the decomposition reforming reaction respectively to the internal combustion engine (1). The ratio of the isomerization reforming reaction and the decomposition reforming reaction depends on a catalyst temperature, and can be altered arbitrarily by controlling an air supply amount to the catalyst (6) via an air amount regulating valve (14) and a fuel supply amount to the catalyst (6) via a fuel injector (8) and thereby controlling the catalyst temperature.
