FUEL INJECTION QUANTITY CONTROL DEVICE FOR ENGINE

摘要

PROBLEM TO BE SOLVED: To accurately determine evaporation from each part in the case spray from an injection valve sticks to at least two parts in an intake port and evaporation characteristics of the fuel sticking to two parts are greatly different from each other. SOLUTION: This fuel injection quantity control device for an engine is provided with an intake valve 15 for opening/closing an intake port 4 of an inlet of a combustion chamber 5; a fuel injection valve 21 for injecting fuel into the intake port 4; and a fuel injection quantity computing means 31 for computing a fuel injection quantity from the fuel injection valve 21 using a model in which the fuel injected from the fuel injection valve 21 diverges in at least two parts to stick to the intake valve 15 and the wall of the intake port 4 and a part of each sticking fuel is evaporated with different characteristics.
