摘要： In a direct injection internal combustion engine, a stratification combustion condition, a homogeneous combustion condition and an intermediate combustion condition which is intermediate the stratification combustion and the homogeneous combustion conditions are controlled selectively according to an operation condition of at least one selected from a combustion condition, an output condition of the engine and an acceleration condition of a vehicle. Without defeating an intended low fuel consumption operation, the engine operates to obtain a reduction of harmful exhaust gas. As a result, by assuring the low fuel consumption operation, an improvement in combustion stability and smoke reduction can both be realized.

摘要： In an electromagnetic fuel injection valve of the axial flow type, a tubular member with both its ends open is disposed in a penetration path that is formed in a stationary core, and an area is sealed between the outer periphery of the tubular member on the side of nozzle and the inner periphery of the penetration path. Further, the path formed between the tubular member and the penetration path is communicated with fuel space formed around the outer periphery of the stationary core. Therefore, the fuel circulates when it is allowed to flow out or flow in via the inner path of the tubular member.

摘要： An engine rotation speed control system which comprises an actuator for prescribing the recovery position of a throttle valve, a recovery position sensor for detecting that the throttle valve is returned to the recovery position, an idle speed control unit for controlling the engine to a predetermined idling speed, and a negative pressure restricting unit for controlling the throttle actuator such that reduction in intake negative pressure to below a predetermined negative pressure is prevented. When the throttle valve returns to the recovery position with the engine speed in excess of an upper limit of the idling speed, the actuator is controlled by the negative pressure restricting unit. When the engine speed falls below the upper limit, the idle speed control unit is actuated. Upon engine starting the actuator is set such that the opening degree of the throttle valve suitable for the engine starting is obtained before the starter starts operating.
