PURPOSE:To make a driver so as to take a proper step conformable, by applying an air cylinder type engine stopper interlocked with a key switch, to the above captioned device for an urban service line bus, while making it detect the disorder, perform its redoing control and give an alarm. CONSTITUTION:In case of an automatic engine stop-restart control device, when an engine stopping condition is materialized, it starts feed of a continuous rating current to a transistor 18 whereby voltage of a batter 1 is impressed on a contact 15 at the stop side. At this time, if trouble or the like happens in a stop- start relay 19, an alarm is given forth. When there is notching abnormal on a voltage rise in the contact 15 and yet a solenoid coil 11 is energized with current, a plunger 12 is pulled up, and air in an air tank 10 flows into an air cylinder, sliding a piston 7 in a right direction. When a plunger 14 drops in a concave part of the piston 7 which is therefore locked up, a contact 16 at the start side comes into a state of being conducted. Therefore, a fuel-up lever 5 is drawn by the piston 7 and an engine 3 is thus stopped. If these is any trouble in motion, redoing control takes place, giving an alarm. |
