The figures provide information about the mechanism of hybrid car and how the engine works through environmentally friendly. Overall, hybrid car has two power sources including smaller petrol engine and electric motor driven by battery which controlled by power control unit. Driving the car in addition use less emissions due to the combination energy by petrol and battery.
At the beginning of the steps, energy produced by petrol engine due to the ignition of fuel. , energy from the engine pulls from battery and petrol engine that controlled by energy control unit. After that, the power of fuel ignition sent to transmission. By the mechanism, the transmission drives wheels and moves the car. Furthermore, with smaller engine, the emissions that produced have declined.
In another source, energy level from moving the car maintained by movement of the car. Furthermore, using battery reduced the petrol engine intensively and produced less emission. Control unit of the energy from battery and petrol engine have responsibility to distribute the energy through electric motor, this unit also active when the car needs extra energy. Finally, power from the motor sent to transmission and drives wheels so that the car moved.
