Abstract
There are provided an intake pressure detecting means for detecting an intake pressure on more downstream side than a throttle valve in an intake passage to an engine, a rotational speed detecting means for detecting a rotational speed of an engine, an engine controlling means for controlling the engine to arrive at a target air-fuel ratio corresponding to the detected intake pressure and the detected engine rotational speed and an abnormality treating means for executing an engine stopping treatment to stop the engine if an intake pressure higher than a set pressure has been detected and an engine rotational speed higher than a set rotational speed has been detected, when an opening degree state detecting means detects that the throttle valve is under a fully closed or substantially fully closed state.
