Abstract
A heating device for an exhaust system of an internal combustion engine and having: a tubular body, where a combustion chamber is obtained on the inside; a fuel injector, which injects fuel into the combustion chamber; at least one inlet opening, which can be connected to a fan so as to receive an air flow, which is directed to the combustion chamber and gets mixed with the fuel; a feeding channel, which receives air from the inlet opening, surrounds an end portion of the fuel injector and ends with a nozzle, which is arranged around an injection point of the fuel injector; and a spark plug, which is mounted through a side wall of the tubular body so as to trigger the combustion of a mixture of air and fuel. The fuel injector is configured to spray at least 80% of the fuel against an inner surface of the feeding channel.
