Efficiency of Hybrid Cars
Hybrid cars are often classed as efficient and environmentally friendly alternatives to the classic fuel-driven alternatives. But where exactly does all of this efficiency come from?
Well, as you may expect it all starts with the motor. Every hybrid car will be powered by two distinct types of engines or motors, the first is a smaller than normal fuel-efficient engine. The second is an electric motor that will automatically recharge when you are driving. The purpose of the electric motor is to assist the gasoline engine when you are accelerating.
Depending on if you are driving a parallel hybrid or a series hybrid determines what exactly the power from the gasoline engine does. In a parallel the two engines work together, while in a series the gasoline engine will either directly power the electric motor, or charge the batteries, enabling the car to go forward.
Hybrid cars also gain efficiency through their design, enabling a smoother ride and high performance. This includes the through use of lightweight materials, advanced aerodynamics to reduce drag, and the use of low-rolling resistance (LLR) tires. These tires are designed to have less drag by being made narrower and stiffer.
Most hybrids also have the ability to automatically shut off the engine when the car is stopped in traffic or at a light. The engine will restart automatically when the car is put back into gear, saving on the energy used and helping the environment. As well as regenerative breaking, which means that the engine that drives the car can also slow it down, in this mode the electric motor is about to charge the batteries while slowing by acting as a generator.
Hybrid cars of today, although relatively new have gone past making just the engine more economical and have succeeded in making all areas of the automobile work for the efficiency of the car.
