Experimental and Numerical Study on the Combustion Characteristics of a Premixed Charge Compression Ignition Engine

The objective of this work is to investigate the effect of premixed fuel ratio on the combustion and emission characteristics in diesel engine by the experimental and numerical method. In order to investigate the effect of various factors such as the mixing ratio, EGR rate, and engine load on the exhaust emissions from the premixed charge compression ignition diesel engine, the injection amount of premixed fuel is controlled by electronic port injection system. The range of mixing ratio between dual fuels used in this study is between 0 and 0.85, and the exhaust gas is recirclulated until 30 percent of EGR rate.
