Title:
FUEL INJECTION CONTROL DEVICE AND FUEL INJECTION CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2015/173937
Kind Code:
A1
Abstract:
A fuel injection control device includes a head-side cooling channel that cools a cylinder head and a block-side cooling channel that cools a cylinder block, and controls fuel injection of a spark-ignited internal combustion engine for direct injection into a cylinder, which is provided with a cooling device capable of independently controlling the circulation of a coolant in the head-side cooling channel and the circulation of a coolant in the block-side cooling channel. The fuel injection control device is provided with a fuel injection timing setting means for setting a fuel injection timing for cooling the inside of the cylinder, as an intake air valve closing timing, during an occurrence of a reduction in gas temperature inside the cylinder due to evaporative latent heat of the injected fuel, while circulating the coolant into the head-side cooling channel with the circulation of the coolant in the block-side cooling channel stopped, and the fuel injection control device injects the fuel on the basis of the fuel injection timing for cooling the inside of the cylinder.
