<p><P>PROBLEM TO BE SOLVED: To realize an accurate fuel injection amount in response to change of a driving condition by resolving an error of a fuel injection amount due to fluctuation of an injection pressure without increasing costs in regard to an add-on fuel injection system constructing a gas fuel injection system by using a gasoline injection system. <P>SOLUTION: In an add-on/gas fuel injection signal generated/outputted in an add-on/gas fuel injection controller, a fuel flow rate index corresponding a fuel flow rate at that time is determined by multiplying an engine speed by a gasoline effective injection time respectively included in a gasoline injection signal, and by correcting a gas fuel effective injection time on the basis of the fuel flow rate index, the error of the fuel injection amount due to the fluctuation of the fuel injection pressure caused by change of the fuel flow rate is resolved. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
