PROBLEM TO BE SOLVED: To provide an injection control device for an engine capable of optimally controlling air-fuel ratio while performing fuel injection control using different logics for calculating injection quantity of fuel. SOLUTION: A sub ECU 31 converts an oxygen sensor signal XO so as to give a delay time at timing of switching between lean/rich and outputs to a main ECU 30 when injecting LPG. The main ECU 30 performs an air-fuel ratio feedback correction on the basis of the converted oxygen sensor signal XO, calculates a gasoline injection quantity TR[gas] and outputs a control signal for a gasoline injector. The sub ECU 31 converts the control signal for the gasoline injector into the one for an LPG injector and outputs it to the LPG injector 19. |
