Study on Effects of Oxydal on Diesel Engine Combustion

Based on the analysis of the high temperature decomposition of oxydal (H2O2) and the combustion of diesel engine, the effects of H2O2 on the improvement of diesel combustion were studied. An oxydal spray system was designed to inject H2O2/water mixture into the manifold. The experiment was carried out on a 1135 diesel engine bench. The results show that H2O2 injection can make the curve of heat release rate move forward and decrease its peak value. The specific fuel consumption is decreased a little, while both NOx and PM emission are obviously reduced.
