The invention concerns a method for additional thermal heating for motor vehicle equipped with pollution-free engine operating with additional compressed air injection into the combustion chamber (2) and having high pressure compressed air storage reservoir (23). The high pressure compressed air contained in the reservoir is previously to its final use at a lower pressure, directed towards a thermal heater (56) to increase its pressure and/or volume before it is injected into the combustion or expension chamber (2). The invention is applicable to all engines equipped with compressed air injection.

[ What is claimed is:] [1.]1. In a thermal heating method for an engine or vehicle equipped with an engine that is free of pollution or that reduces pollution, operating with injection of additional air into a combustion or expansion chamber and which has a high-pressure compressed-air storage reservoir, the improvement which comprises:expanding compressed air contained in the high-pressure storage reservoir, prior to its final use at a lower pressure and prior to being introduced into a thermal heater to allow at least one of its pressure and its volume to increase before it is injected into the combustion or expansion chamber, to a pressure in a variable-volume system, producing work, the consequence of which is that of cooling the compressed air thus expanded to a low temperature,thereafter sending the thus-cooled air into a heat exchanger to heat it and thus increase at least one of its pressure and its volume by recovering additional heat energy from ambient surroundings.
