Abstract (en)

[origin: EP0775822A1] The method employs a burner (5) acting directly on a gas-liquid heat exchanger (6) integrated into the coolant circuit (7) of the engine (1) and installed in the exhaust pipe (8). The coolant is pumped (2) also through an oil cooler (3), a heater (4) in the passenger accommodation, and a radiator (10) having an inlet thermostat (9). The burner operates while the engine is cold (i.e. coolant temperature is below about 50 degrees C), for a limited duration depending on ambient temperature and engine load. Heat recovery of the order of 10 kW is claimed in the coolant circuit of an average engine, whose warm-up time is halved and the passenger heater benefits by an average of 5 kW.
