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.
