    摘要： A direct-fuel-injection-type spark-ignition internal combustion engine has an ignition plug, a cavity formed in an upper wall of a cylinder, a fuel injection valve that injects fuel so that most of the fuel strikes a side wall of the cavity at an acute angle with respect to a tangent to the side wall at the point where the fuel strikes it, and a fuel guide portion that is provided in the side wall of the cavity and that guides most of the fuel to the vicinity of the ignition plug. The direct-fuel-injection-type spark-ignition internal combustion engine is able to realize a good stratified charge combustion by reliably positioning a major portion of combustible mixture in the vicinity of the ignition plug at the time of ignition.

    摘要： A direct fuel injection, spark-ignition internal combustion engine wherein fuel mainly proceeds toward a spark plug side wall of a cavity along a bottom wall, is deflected by the spark plug side wall and is led to the vicinity of a spark plug. In the engine, the spark plug side wall of the cavity is provided with a deflecting portion inclined toward the inside of the cavity. A first part of the deflecting portion provided on both sides of the spark plug side wall functions to lead the fuel to the vicinity of the spark plug. A second part of the deflecting portion on the central portion of the spark plug side wall functions to lead the fuel to a region neighboring the side of the fuel injection valve from the vicinity of the spark plug.

    摘要： A direct fuel injection-type spark ignition internal combustion engine is disclosed. The engine comprises a spark plug arranged in the upper wall of the cylinder, a fuel injector for directly injecting fuel into the cylinder, and a cavity formed in the top surface of the piston. The cavity has a bottom wall and a spark plug side wall. Fuel injected into the cavity from the fuel injector in the latter half of the compression stroke proceeds on the bottom wall of the cavity so as to be deflected by the spark plug side wall and led to the vicinity of the spark plug. In the engine, the fuel injector injects fuel in the shape of a fan having a relatively small thickness. The cavity has guide walls for preventing fuel from excessively spreading in the direction of width of the fan shape as it proceeds on the bottom wall.

    摘要： A direct cylinder injection-type spark ignition internal combustion engine is disclosed. The internal combustion engine comprises a spark plug 6, a cavity 8 formed in the top surface of the piston, and a fuel injection valve 7 for injecting fuel into said cavity in nearly the shape of a fan having a relative small thickness. A side wall 8b of the cavity opposed to the fuel injection valve for leading the fuel to the vicinity of the spark plug, has a horizontal arcuate shape which is nearly symmetrical to a first vertical plane (N1). The first vertical plane is separated away from a vertical center plane (Nc) at the center of the fuel and is nearly parallel with the vertical center plane.

    摘要： In an internal combustion engine, fuel enrichment is carried out when an acceleration state occurs after a transition from a fuel cut-off state to a fuel cut-off recovery state, the fuel enrichment is determined by taking into consideration the amount of fuel supplied to the engine between the above-mentioned transition and the occurrence of the acceleration state.
