摘要：
The present invention provides a control apparatus used in an internal combustion engine that can switchably use a compressed natural gas and gasoline. The control apparatus carries out a miss fire check on the internal combustion engine over two or more combustion cycles, and, based on the results of the check, detects failures. The control apparatus prohibits switching of fuels (S23, S24, S28) basically during the miss fire check. If the value of a miss fire counter is not increasing, the control apparatus predicts that a negative check result will not be obtained (S26), and lifts the prohibition on switching of fuels (S29).
