EFFECT OF PREMIXED RATIO ON NITRIC OXIDE EMISSION IN DIESEL ENGINE 2001-01-1806

The objective of this work was to experimentally determine the effect of premixed fuel on the reduction of exhaust emissions in diesel engine. In order to investigate the effect of premixed ratio on the NOx and smoke in a diesel engine, the reduction effect of exhaust emissions of diesel engine is investigated by means of experimental method. In this work, a direct injection type diesel engine with M-combustion chamber modified by using the supply system of premixed fuel into the intake manifold. The experimental apparatus consist of premixed fuel system, diesel injection system and electronic control system. The injection amount of premixed fuel in the intake port controlled by electronic injection system.
The results of this study show that the increase of premixed ratio of supplied fuel reduce the nitrogen oxide and smoke emissions of the engine. Based on the experimental results, the reduction of exhaust emissions and the other combustion characteristics in a small direct-injection diesel engine were discussed.
