摘要

Compared with turbocharging, the hybrid electric supercharging technology can improve the air intake volume and responsiveness of engine. The influence of rotating speed of electric supercharger on engine torque, air-fuel ratio and economy is studied to obtain the best working point of electric supercharger. The performance of electric hybrid supercharged engine is simulated based on the power, intake power and combustion effeciency of exhaust lurbocharger. The performance of hybrid electric turbocharged engine was compared with that of the original engine.The results show that the hybrid electric turbocharging system can effectively improve the performance of engine in the low rotating speed and high torque area, the low rotaing speed and high torque area of engine is increased by about 18%, and the fuel consumption is increased by about 16.7% in the area below 220 g/kWh; in the indicated power increment, the power increment of power cycle is far greater than that of the supercharging power; and the supercharging power increment is mainly increased by the supercharging power of the exhaust gas turbocharger. The main reason for the increase in turbocharging power is the enthalpy drop of exhaust gas turbine.
