FUEL INJECTION CONTROL DEVICE

摘要

A fuel-supply system of an engine (10) is provided with: a gas tank (23) in which gas fuel is stored under high pressure; a gas injection valve (14) for injecting the gas fuel supplied from the gas tank (23) via a gas passage (22); and a regulator (30) for adjusting the injection-side supply pressure. A microcomputer (51) calculates, on the basis of the engine operation state, a basic injection amount of gas fuel to be injected from the gas injection valve (14). When a transient change of the fuel injection amount to be injected from the gas injection valve (14) occurs, the microcomputer (51) corrects the basic injection amount on the basis of tank-side pressure.
