ABSTRACT:
A fuel injection control device in a cylinder direct injection engine which switches between premixed combustion by intake stroke injection and stratified combustion by compression stroke injection in accordance with a change of an engine speed or a required load, where an unpleasant torque shock occurring when the injection mode is changed and the combustion state is changed despite the vehicle operating in the driving pattern such as driving on an upward slope or downward slope is prevented by maintaining the same injection mode while the vehicle continues to operate in the same driving state and where stratified combustion by the compression stroke injection is carried out when the vehicle is in driving on a downward slope, but is augmented by intake stroke injection when the vehicle sharply accelerates and the torque becomes insufficient.
