Title:
FUEL INJECTION CONTROL DEVICE AND FUEL INJECTION CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2016/027354
Kind Code:
A1
Abstract:
An internal combustion engine is provided with a port injection injector that injects fuel into an intake port and a direct injection injector that directly injects fuel into a combustion chamber. When the internal combustion engine is in a low load state and requires fuel supply, a controller stops fuel injection by the port injection injector and causes the direct injection injector to inject all of a required fuel injection amount. By this process, a fuel pressure of the direct injection injector in the low load state is lowered quickly.
