Self-propelled crushing machine

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.

Engine overheat prevention system

A noise-proof and air-cooled enclosure system for an engine comprising a radiator compartment, a generally enclosed engine compartment separated from said radiator compartment by a partition wall, said radiator compartment being arranged sideways with respect to said engine compartment, and an ejector utilizing the flow of gases from an engine exhaust pipe for creating a relatively low pressure within an air outlet from said engine compartment to draw ambient cooling air through said radiator compartment into said engine compartment around said engine and out of said air outlet.
