    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： A direct injection engine and a controller for the engine, which can realize super-retard combustion under high backpressure and can minimize an emission amount of HC at the startup. A cavity is formed in a piston such that fuel spray injected from a fuel injection valve is blown into the cavity. An obstacle member, such as a step, is provided in the cavity to decelerate or stop the fuel spray blown into the cavity. A mount position, mount posture, nozzle structure, injection port shape, etc. of the fuel injection valve are set such that the fuel spray injected from the fuel injection valve is made up of a lead fuel spray component directed toward the ignition plug and having a penetration to extend long beyond the ignition plug, and a main fuel spray component directed toward the piston, thereby enabling the super-retard combustion to be performed under high backpressure.
