An Experimental Investigation on a New Combustion System of Diesel Engine for Performance Optimization

Abstract:

In this work, based on the concept of spray-orientation and space-atomization, a new double-layers diffluent combustion system for diesel engine is proposed which has a collision table with circular oriented-surface. Experiments are carried out on a 135 single-cylinder diesel engine by utilization of the new combustion system which is equipped with a high-pressure common-rail fuel injection system. The optimized rail pressure and fuel injection advanced angle are selected for diesel engine at different work conditions. Comparing with the data of original combustion system, the decrease of the brake specific fuel consumption and soot emission is 3.10% and 31.8% respectively while the NOX emission increased by 8.49% at rated work condition for this new combustion system. These results indicate that the new double-layers diffluent combustion system can preferably optimize the performance of diesel engine.
