Abstract:
Method for cold starting automobiles with internal combustion engines comprising a cooling circuit of the engine including an integrated gas/liquid exchanger in cooperation with a burner and an exhaust line with a catalyst, said method consisting of providing the automobile with at least one burner and a device for recovering the calories produced by said burner, wherein the calories recovered are restored to an internal cooling circuit of the engine; wherein said burner is used to heat the catalyst, and an integrated gas-liquid exchanger in cooperation with said burner built into the internal cooling circuit of the engine, wherein said burner heats exhaust gases from the engine, such that the intake air, engine oil, the walls of the engine and the passenger compartment are heated due to the heating of the internal cooling circuit by heat of combustion gases of the burner captured by the cooling circuit, and wherein the burner is made to operate for a specific period of time depending upon the speed and load on the engine.
