Abstract
A system for preventing engine overheat in a vehicle such as a motor scraper or the like having a front engine and a rear engine mounted thereon. An actuator is operatively connected to the rear engine for controlling speed thereof and also is connected to a source of pressurized fluid through a solenoid-operated valve. A plurality of detectors are mounted in the rear engine each detecting a preset abnormal condition of the rear engine. Provided in the system is a relay responsive to a signal from the detectors for simultaneously turning on a warning lamp and energizing the solenoid-operated valve thereby blocking communication between the source of pressurized fluid and the actuator, thereby reducing the speed of the rear engine to its idle speed.
