Method for operating internal combustion engine

摘要

This invention relates to a method of operating an internal combustion engine which comprises placing a reaction cylinder filled with a catalyst for partially oxidizing a hydrocarbon-base fuel within an exhaust gas passage, feeding a mixture gas consisting of hydrocarbons and a gas which contains oxygen of a quantity providing an "oxygen-to-carbon ratio" of 0.3 to 1.2 into the reaction cylinder, partially oxidizing the hydrocarbons into a reformed gas which consists essentially of H2 and CO in the temperature range of 800 DEG to 1200 DEG C., mixing the reformed gas and a gas containing oxygen of a quantity providing "an excess oxygen ratio" of 1.1 to 2.0, and feeding this mixed gas into an intake manifold of the internal combustion engine.
