ABSTRACT:
A device for and process of pre-heating the intake air of a supercharged, low-compression ratio Diesel engine when operating at low loads, comprising the apparatus for and steps of taking the heat required for said pre-heating from at least one portion of the exhaust gases of said engine and conveying it to at least one part of the intake air. The device includes heat exchange apparatus having a heating fluid inlet connected to the diesel engine exhaust line through a three-way valve, a heating fluid outlet, a heated fluid inlet, a heated fluid outlet connected to the intake air duct of the engine, and a heat conveying means moving in a closed path between the heating fluid and the heated fluid. A temperature sensor in the air intake duct controls the three-way valve to apportion the flow of exhaust gases between the heating fluid inlet and the atmosphere to maintain a predetermined minimum intake air temperature.
