In diesel engines, there is a problem that both smoke and nitrogen oxide cannot be reduced simultaneously. There have been many studies on solving this problem. One of the solutions is the utilization of gaseous fuel. Gaseous fuel is inducted from an intake port and the combustion starts by injecting light oil. Hydrogen is considered as a future fuel without exhausting carbon dioxide. In this study, hydrogen was inducted from the intake port into the cylinder of a diesel engine and light oil was injected in the cylinder. The heat release rate was determined from the pressure history in the cylinder. The relation between 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 NOx are reduced simultaneously while brake thermal efficiency is slightly lower.
