How Do Hybrid Vehicles Work?
It is easy to save fuel with two motors
Why are hybrid vehicles so fuel efficient?
This all is very simple – these cars just burn gasoline when it is necessary. Judging by the term itself we can see that the car under its hood combines two engine types – a standard gasoline powerplant and a powerful electric engine.
The electric engine is provided with rechargeable batteries. It is the main power which moves the car during driving with slow speed, for instance, in stop-and-go city traffic. When a motorist taps on the brakes lightly, for instance during slow down phases and coasting, the wheels of the car are automatically engaged to electrical generator. To slow the car down the extra load id made by this generator. It also serves to convert the mechanical energy of the car into electricity back thus recharging the batteries.
When the car is driving with the higher speed, during steady road cruising, for example, the gas-burning engine is automatically turned on by the computer thus becoming the main driving power of the vehicle. Small vehicles are usually provided with VVT-I - variable valve timing intelligence. This device helps burn the fuel most completely and efficiently.
The two car’s motors can work in conjunction. For example, you need to or pass a tractor-trailer truck. Your computer automatically turns on the electric engine thus providing necessary acceleration boost. In its turn the gas engine automatically switches on to charge the vehicle’s batteries if they fall below a certain charge level. That is why you never need to plug your hybrid in at night. This is one of the points which need to be clarified for many dealers and consumers. Engine combination offers the best of two principally different cars – gas-powered and electric.
When the car stops completely, during rush hours, for example when other vehicles just waste fuel, hybrid does not use any gas at all. When the driver needs to move the vehicle forward, the electric motor switches on and propels the vehicle. Hybrid cars save fuel and consequently they save your money as their owners need to fill hybrids less frequently than gas-powered cars – in average every 400 to 600 miles.
