    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 fuel injection internal combustion engine (1) is started up by means of compression stroke fuel injection from the beginning of cranking of the engine (1) to the end of a stratified combustion start-up period TST. If the engine (1) reaches complete combustion during the period, a warm-up operation is begun immediately. If the engine (1) does not reach complete combustion during the period, start-up of the engine (1) is continued using intake stroke fuel injection. By means of this control, stable start-up is assured while suppressing the discharge of unburned fuel during start-up of the engine (1).
