Motor vehicle i.e. road vehicle, has feeder line supplying cooling system with compressed air, and control unit controlling supply of cooling system with compressed air depending on signal delivered by sensor

摘要

The vehicle has an engine with a liquid cooling system (2) for cooling the engine. A coolant of the liquid cooling system stays under a preset high pressure during operation of the engine. A sensor (14) detects an operating condition of the engine and outputs a characteristic signal of an operating condition. A feeder line (12) is provided between a compressed air system (10) and the cooling system and supplies the cooling system with compressed air. A control unit (30) controls the supply of the cooling system with compressed air depending on the signal delivered by the sensor. An independent claim is also included for a method for operating a motor vehicle engine.
