Abstract

In order to meet emission standards for nonroad diesel engines and improve the quality of gas mixture, a new swirl chamber combustion system was brought forward. The external supercharging system in diesel engine is investigated. Experimental research in a singer cylinder 135 diesel engine with four valves is accomplished using swirl combustion chamber under several different supercharging pressures. The results showed that fuel consumption and emissions are reduced under external supercharging, and there is minimum fuel consumption under supercharging pressure of 0.15MPa. Under supercharging pressure of 0.18MPa, NOx emission is lower 600×10^-6 than that of normal pressure at 8°CA BTDC of fuel supply advanced angle in swirl combustion chamber. The four-hole nozzle is used at 90 percent load, which diameter is 0.36mm, and nozzle hole cone angle is 140°.
