Performance Analysis on Electrical Aided Turbocharged System
A turbocharger is fitted to a diesel in order to enhance the inlet charge pressure, hence increasing the fresh air in the cylinder, then more fuel can be injected into the cylinder and sequentially more engine power can put out. The electrical aided turbocharged system is a mechanism adding a high speed electronic motor into a turbocharger shaft. The electronic motor can work as a motor to drive the turbocharger shaft and as a generator to generate electricity energy to storage energy. According to certain constraint conditions, the controlling strategy of the hybrid turbocharged system is presented. The simulation results about key work points reveal that controlling the turbocharged engine following the strategy can enhance the engine performance.
