Abstract:
1. A combustion control apparatus for a diesel engine comprising: an injector disposed so as to extend into a combustion chamber of a cylinder of the engine, and an injection control means for controlling the injector to inject fuel at least during one of the intake stroke and compression stroke, so as to attain a first combustion state where the ratio of a premixed combustion is larger than that of a diffusion combustion, while the engine is in a predetermined operational condition, wherein, said injection control means adjusts at least one of a period during which the injector opens its valve and the injection pressure of the fuel injected by the injector, at least based on a fuel injection timing, while the engine is in the predetermined operational condition, and said injection control means performs at least one of the controls of shortening the valve opening duration of the injector as the fuel injection timing is advanced, and lowering the injection pressure as the fuel injection timing is advanced.
