Exhaust Characteristics Simulation of the Hybrid Electric Car

Saving energy and protecting the environment are regarded as two main problems f or the world . Because cars amount to about 80% of the existing automobiles in the world, it is urgent to develop new energy-saving powertrain and clear fuel. The hybrid powertrain is regarded as on e of the ways to save energy and protect the environment. When traditional hybr id powertrains are introduced, a new minimal hybrid electric car is proposed. Af ter its principle and its control strategy are introduced, its exhaust model is established. Also, a simulation is performed with the simulation program edited by the author. The simulation result shows that the minimal hybrid powertrain c an reduce exhaust significantly.
