METHOD FOR GENERATING GAS INJECTOR DRIVING SIGNAL WITH GASOLINE INJECTOR DRIVING SIGNAL

摘要

PURPOSE: A method for generating a gas injector driving signal with a gasoline injector driving signal is provided to remove a separate ECU(Electronic Control Unit) for gas and improve productivity by computing a fuel injection time of the gas at the real time with comparison to a gasoline injection time to a correction coefficient. CONSTITUTION: A method for generating a gas injector driving signal with a gasoline injector driving signal is composed of steps for computing a gasoline injection time based on information input from a peripheral sensor to set a correction coefficient and the gasoline injection time based on the information input from the peripheral sensor for setting an initial gas injection time and the gasoline injection time; computing time difference between the present computed gasoline injection time and the initial gas injection time if a value of the correction coefficient is not over 1 and computing gas injection starting and finishing points delayed for the time difference from the starting point of the gasoline injection time(S217); regarding the starting point of the present computed gasoline injection time as the starting point of the gas injection time if the value of the correction coefficient is over 1 and computing the gas injection time by multiplying the present computed gasoline injection time and the value of the correction coefficient(S207,S223); and computing the gas injection finishing point by delaying the gas injection time from the gas injection starting point.
