Abstract
A device and method for assisting cold start of automobiles with internal combustion engines which include a cooling circuit and an exhaust line with a catalyst. The method includes use of at least one burner and a means for recovering the calories produced by the burner, where the calories recovered are restored to at least one of the following elements: the intake air, the walls of the engine itself, the internal cooling circuit of the engine, or the passenger compartment heating means. A burner is used directly to heat a gas-liquid exchanger built into cooling circuit of engine, as well as the engine exhaust gases. The intake air and vehicle passenger compartment thus benefit from the improved heating of the cooling circuit.
