    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.

    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, including a main combustion chamber serving as a main combustion chamber, an auxiliary combustion chamber adjacent to the main combustion chamber and smaller in capacity than the main combustion chamber, and a partition wall between the main combustion chamber and the auxiliary combustion chamber, the partition wall including an injection hole by which the main combustion chamber and the auxiliary combustion chamber communicate. A fuel supply device supplies fuel to the main combustion chamber and the auxiliary combustion chamber. A mixture forming device forms a mixture of air and the supplied fuel in the main combustion chamber, away from the partition wall before ignition. An ignition device ignites the fuel in the auxiliary combustion chamber, propelling an ejecting torch flame into the mixture of air and fuel in the main combustion chamber through the injection hole, thereby burning the mixture of air and fuel in the main combustion chamber.
