    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： An internal combustion engine, including a premixed mixture formation device that forms a premixed mixture of fuel and air in a combustion chamber, a fuel gas supply device that injects fuel gas directly into the combustion chamber, and an ignition device that ignites the fuel gas. The fuel gas supply device is configured to inject the fuel gas into the premixed mixture near a top dead center of a compression stroke such that a spray of the fuel gas passes through a firing position of the ignition device, to produce the spray of the fuel gas in a predetermined area substantially extending from one end of a cylinder bore to the other end as viewed in a cylinder-bore direction defined by a centerline of the cylinder bore. The ignition device is configured to directly ignite the spray of the fuel gas and to ignite and burn the premixed mixture by way of flame propagation along the spray of the fuel gas.

    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.
