    摘要： A control method of an internal combustion engine with which braking force while reducing the speed of the motor vehicle can be established by generating pumping loss effectively by using a variable valve mechanism enabling to control arbitrarily the open-close timing and the lift amount of air intake and exhaust valves of the engine. When the break step-on force detection means detects a step-on force on a brake and an operation of the anti-lock brake system is selected, at least one of the intake valve or the exhaust valve is made close, another one not closed of the intake valve or the exhaust valve is made open once in a single revolution of the engine while a piston moves from a top dead center to a bottom dead center, and a lift of the valve is controlled to be a designated value.

    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.

    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.
