Performance of Euro III common rail heavy duty diesel engine fueled with Gas to Liquid

The effect of synthetic diesel fuel made from natural gas (Gas to Liquid, GTL) on the engine performances (such as power, efficiency and emission) was carried out on one Euro III common rail (CR) heavy duty (HD) diesel engine without any modification. The results showed that the engine fueled with GTL had some variations compared with the one fueled with petroleum-based low sulfur diesel fuel (sulfur content less 50 ppm). The maximum torque and power were decreased by 1.3% and 1.9%, respectively. The specific fuel consumption increased in volume but had no change in mass. Under the load characteristics, the NO_x, CO and THC were reduced by 13%, 55% and 55%, respectively. During the ESC cycle test, the NO_x, CO, THC and PM were reduced by 5.2%, 19.3%, 19.8% and 33%, respectively.
