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： The piston 4 is one whose top part has a flat shape. Fuel is injected directly inside the cylinder 1 from the fuel injection valve 2. The tumble air flow control valve 7 adjusts the strength of the tumble air flow. The injected fuel pressure control section 110 of the control unit 100 varies the injected fuel pressure in accordance with the rotational speed of the engine while maintaining constant the opening angle of the tumble air flow adjustment valve 7. The TCV opening angle control section 120 varies the opening angle of the tumble air flow adjustment valve 7 in accordance with the rotational speed of the engine while maintaining constant the injected fuel pressure. The control is made by switching between the injected fuel pressure control section 110 and the TCV opening angle control section 120 depending on the rotational speed of the engine.

摘要： A fuel injector employed in a direct injection engine comprising a spark plug arranged on the top of a combustion chamber, a fuel injector located on said combustion chamber and an intake air control means installed on an intake manifold. A forward tumble air flow is formed in the combustion chamber by the intake air control means, and the fuel injector is available in two types; an annular (conical) spray type characterized by uniform density and a spray type characterized by high/low density. In the case of latter type, arrangement is made to ensure that the denser portion is placed face-to-face with the spark plug. Spray fuel rises along the wall surface of the combustion chamber on the intake side, and is carried to the spark plug by forward tumble air flow (called “tumble guide”) moving from the fuel injector to the spark plug. This allows stratified charge combustion to be performed in the operation range from low to high speed ranges, with the result that discharge of gas containing hazardous gas component such as THC is reduced and fuel economy is improved.

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.
