    摘要: A direct-injection internal combustion engine and a combustion method therefore in which fuel injection timing of a fuel injection valve is so configured that (a) the fuel inverted from a cavity in a crown portion of a piston reaches proximity to the discharge electrode portion of a spark plug later than the time of ignition or (b) fuel injection by the fuel injection valve is completed at approximately the same time of ignition. There is no risk of rich combustion at the discharge electrode portion due to the mixed fuel-air mass having a high fuel density, and consequently problems such as wear on the spark plug or smoke generation can be avoided.

    摘要: A start-up control device of a direct injection engine has a fuel injector (76) for injecting fuel into the engine; and a controller. The controller is programmed to determine the presence of a learned value for calculating on the basis thereof a fuel injection amount during start-up of the engine (10) by means of a stratified charge combustion operation; calculate the fuel injection amount on the basis of the learned value when the learned value is present, and control the fuel injector (76) to inject fuel in the compression stroke to start up the engine (10) by means of a stratified charge combustion operation; and control the fuel injector (76) to inject fuel in the intake stroke of the engine to start up the engine by means of a homogeneous combustion operation when the learned value is absent, and obtain and store the learned value during the homogeneous combustion operation of the engine.

    摘要: An in-cylinder direct fuel injection engine is disclosed. The engine comprises a fuel injection valve engaged in a fuel injection hole, a cylinder head, and an ignition plug engaged in an ignition hole, The fuel injection valve is attached to the fuel rail and the fuel injection nozzle injects fuel from the fuel rail. The fuel injection hole and the ignition hole are positioned in a central portion of the a roof of the cylinder head so as to be located between an intake and exhaust air ports and are generally aligned along an axis of a crank shaft.

    摘要: An exhaust gas recirculation system is configured to recirculate a large amount of exhaust gas to an engine intake passage while reducing contamination inside the intake passage caused by the recirculated exhaust gas and prevent damage to the intake passage caused by the heat of the recirculated exhaust gas. A first recirculation path recirculates exhaust gas from an upstream section of the exhaust passage located upstream of a catalytic converter unit. A second recirculation path recirculates exhaust gas from a downstream section of the exhaust passage located downstream of the catalytic converter unit. A control unit is provided that controls the switching of a selector valve between the first and the second recirculation paths based on the temperature of the recirculated exhaust gas.
