Title:
FUEL INJECTION CONTROL APPARATUS AND CONTROL METHOD OF INTERNAL-COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2016/203634
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 injects the fuel into a combustion chamber. A controller causes the port injection injector and the direct-injection injector to inject fuel on the basis of operating conditions of the internal-combustion engine. In addition, the injection amount of the direct-injection injector during deceleration of the internal-combustion engine is made to be greater than the normal injection amount of the direct-injection injector, thereby rapidly reducing the fuel pressure of the direct-injection injector.
