Title:
FUEL INJECTION CONTROL DEVICE FOR DIRECT INJECTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2016/152102
Kind Code:
A1
Abstract:
This fuel injection control device for a direct injection engine is provided with an engine body (engine 1) and a fuel injection control unit (engine controller 100). At the point in time when an air-fuel mixture ignites while the engine body is warming up, the fuel injection control unit injects fuel into a combustion chamber (17) in a prescribed injection mode so that an air-fuel mixture layer and a heat-insulating gas layer in the periphery thereof are formed in the combustion chamber. When the engine body is cooling down, the mode of injecting fuel into the combustion chamber is altered so that the thickness of the heat-insulating gas layer decreases commensurately with reductions in the temperature of the engine body
