Abstract
Disclosed herein is a fuel injection control device for a direct injection engine including an engine body (engine) and a fuel injection control unit (engine controller). The fuel injection control unit injects a fuel in a predetermined injection mode into a combustion chamber () such that while the engine body is warm, an air-fuel mixture layer and a heat-insulating gas layer, surrounding the air-fuel mixture layer, are formed in the combustion chamber at a point in time when an air-fuel mixture ignites, and changes the injection mode of the fuel into the combustion chamber such that while the engine body is cold, the lower the temperature of the engine body is, the thinner the heat-insulating gas layer becomes.
