Abstract
A bench experiment on soot emission of an armed vehicle's diesel engine with oxygenate fuel was carried out. The effects of bio-diesel fuel and dimethyl carbonate (DMC), as oxygenate additive, on engine smoke were investigated. The results show that, adding bio-diesel of 20% into the fuel, the cylinder pressure curve moves forward slightly, the performance drops a little, and the soot emission decreases by 22%～46% in middle and high speed with 0~100% load; adding bio-diesel of 20% and DMC of 10%, the cylinder pressure curve moves backward and the peak value decreases, the external characteristic torque drops by 5%, the soot emission decreases by 25% to 61.5%. The NOx emission for both cases increases by 10% in some conditions.
