Abstract:
The parameters of the hybrid turbocharging system are adjusted and optimised after simulation.The method is to magnify the flow rate of a turbine and decrease the power of a high-speed motor.Downsizing the motor can directly make the engine lightweight and greatly reduce the moment of inertia for the turbocharging system.Magnifying the flow rate of a turbine can not only reduce the BSFC(Brake specific fuel consumption) in the frequent engine conditions,but also boost the potential of engine drivability in the low-speed and high-load condition.Compared with the original wastegated diesel engine,the adjusted hybrid turbocharged engine can minish the BSFC disturbance from the inappropriate advanced exhaust angle.
