PURPOSE:To make it possible to readily start an engine, by resting an abnormally low rotational speed detecting circuit for a predetermined time period with the use of a resting circuit upon engine starting, so that sufficient fuel gas is fed to an engine. CONSTITUTION:A resting circuit 49, when a key switch 48 is turned on energizes a cerium starter S through a starting circuit E for starting an engine 1. At this time sufficient fuel gas is fed to the engine since an one-shot timer ceases transmitting abnormal signals from an abnormally low rotational speed detecting circuit 29 and an abnormal hydraulic pressure detecting circuit 20, to an OR circuit 47 through an OR circuit 31 and an AND circuit 46 due to that the rotational speed is below a predetermined value until the rotational speed sufficiently rises. Thereby, the engine is surely started. |
