摘要： Improvement of combustion stability in retard ignition at the time of starting in a cold state, high output in a full throttle condition, reduction of smoke, and prevention of wear of the cylinder liner caused by oil dilution, are to be attained. In connection with the flow of fuel into each hole and a fuel inflow angle which is determined by the axis of each hole formed in a plate, the fuel inflow angle of an hole directed to a spark plug is set large to reduce an effective flow path area, thereby making the amount of fuel in the hole smaller than in other holes. A shallow cavity is formed in a piston crown face and a small prominence confronting fuel sprays is formed within the cavity.

摘要： A combustion chamber is formed using a flat piston having a low cooling loss and therein a forward tumble is generated. A fuel spray is formed by a provision of a splitter which is provided to make off-set from a center of an injection port at a tip end of a tumble atomization system fuel injector. The fuel spray is divided into a fuel spray having a strong penetration force and a fuel spray having a small penetration force. The fuel spray having the strong penetration force is injected in a vicinity of an ignition plug. Accordingly, a fuel adhesion to the piston can be reduced and further a reduction of a discharge HC and a fuel consumption can be improved.

摘要： In a cylinder injection engine and a control device for the engine, for achieving both of the decrease of a particulate matter by suppression of fuel adhesion on the piston during fast idling of cold start and ignition retard fuel by stratification of a mixed gas around an ignition plug, a closing timing of a suction valve is set to a middle stage of a compression stroke in which a piston moving speed becomes maximum, while the furl adhesion to the piston is decreased by injecting the fuel for stratification onto the ignition plug in the vicinity of a piston bottom dead center, and when the piston is raised in the compression stroke, the mixed gas flows from a combustion chamber to a suction pipe to generate a rising flow, and by this rising flow, the mixed gas is stratified around the ignition plug.
