Filed: 1983-04-05
Abstract: PURPOSE:To prevent drinking drive effectively by blowing expiration of driver to a detection head to detect the expiration then detecting existence of alcohol in the expiration thereby disabling/enabling engine start with correspondence to whether it exists or not. CONSTITUTION:When driving a car, the driver will first blow his expiration to a detection head arranged at predetermined position in the cabin, then first sensor 4 will detect the expiration to energize a relay R2 thus to close a switch 5 and to close the electric circuit in engine firing system thus to form a circuit of startable state. If alcohol exists in the expiration, second sensor 6 will detect alcohol to energize relay R1 thus to open a switch 7 while to de-energize relay R2 to open a switch 5 thus to form a circuit of non-startable state. Since engine start can be disabled for driving under drinking state, drinking drive can be prevented effectively.
