    Abstract:In order to solve the engine turbocharger surge appeared at an attitude of 2500m and overspeed appeared at attitude of 4500m, a solution of double turbocharger was put forward. To this end, a GT-Power software was used to predict the external characteristics of the new engine and test results were compared with the original engine performance. Results show that the new scheme can effectively solve the problems of the original engine. At an attitude of4500m,the maximum torque reaches1844N•m（1300r/min）, which is 6.8% lower the original engine test value of 1980N•m,and the maximum power reaches 241.5kW（2100r/min）， which is 24.7% lower than the original engine test value of 330kW in the plain.
