In diesel engines, there is a problem that smoke and oxide of nitrogen cannot be reduced simultaneously. There have been many studies on solving this problem. One of the solutions is an engine that uses gaseous fuel. Gaseous fuel is inducted from an intake port and the combustion starts by injecting light oil. And hydrogen is considered to be future fuel without exhausting carbon dioxide. In this study, hydrogen was inducted from intake port into the cylinder of a diesel engine and light oil was injected in the cylinder. The heat release rate and the exhaust emissions are discussed. As a result, when hydrogen is mixed with the inlet air, exhaust emissions such as smoke, hydrocarbon, CO, CO_2, and NO_x are reduced simultaneously though brake thermal efficiency is slightly low.
