Abstract: The experimental system was established in order to study the dynamic and economic performance of vehicle engine fuelled with LPG. Based on the experimental system, the variable experimental study including engine power, torque and consumption rate were carried out. The l results showed that with the rise of the engine rotational speed, power and torque of the engine fueled with LPG increased first and then decreased, but all of them were lower than that of the 93#gasoline. The consumption rate of the LPG was better than the 93#gasoline for the engine case at 2000r/min and 4000r/min on the energy consumption rate.
