ABSTRACT:
An HC (hydrocarbon) supplementing device is mounted in an exhaust purification device of an internal combustion engine, wherein the amount of HC in the fuel to be added is automatically adjusted to a degree corresponding to the operating conditions of the engine. Accordingly, the supply of just enough HC becomes possible without the use of a complex mechanism for adjusting the supply of HC, and the exhaust gas can be sufficiently purified without wasting fuel.
