摘要： This invention proposes a fuel injection control device for a direct injection engine which performs stable stratified charge combustion by increasing the degree of charge stratification in the air-fuel mixture through discrete double fuel injection by a fuel injection valve (12) during the compression stroke. In a predetermined operating region, the fuel injection control device for a direct injection engine divides the fuel injection pulse signal generated during compression stroke into two signals having approximately the same pulse width. The interval between the first and the second fuel injection pulse signals is determined so that a mixture cloud (32) produced by a fuel spray injected on the basis of a second fuel injection pulse signal catches up with and is superimposed on a mixture cloud (31) produced by a fuel spray injected on the basis of a first fuel injection pulse signal. The two mixture clouds are superimposed in the proximity of a spark plug (7) at the ignition timing.
