Abstract :
The fuel supply system of after-cooling diesel engine, D6114ZLQB, has been reformed based on the characteristic of D30(the ratio of DME/Diesel is 3/7). A series of emission tests have been processed under different fuel supply-advanced angles and injection starting pressures. The result shows: reduction of fuel supply-advanced angle has great influence on the emission of NOx, but little influence on PM; the emission of PM would increase and NOx decrease when reducing the fuel injecting pressure. During the whole speeds, CO and HC have not apparently changed.
