How Hybrid Cars Became A Success?

By Danny Green

The invention of car was made to provide easy mode of transportation to consumers, and at that time nobody had ever thought about the environmental effects of this invention such as, its fuel-effectiveness. Today it has become impossible to live with this ignorant notion. The reason is that today the world is entirely different than it was in the 18th century because at that time the environmental impact of cars was not considered.

The evolution of cars is very interesting. The engine of the first car was based on steam. As more developments were made, the steam engine was replaced by electric motor along with storage batteries. Porsche, a German, invented the first hybrid car. He used an internal combustion engine to spin a generator. The generator in turn provided power to the electric motors located in the hubs of the wheel. This car could travel up to 40 miles on battery alone.

The basic concept of two kinds of engines for propulsion power was laid down by Porsche; these engines include gasoline/diesel and electric engines.

The cars which are solely based on gasoline, diesel or electric motors have few drawbacks. The major concern caused by the other cars is the environmental vulnerability. The maximum power per pound is provided by fossil fuels; however, since their reserves are few and the prices shoot up quickly, therefore, they are not used for energy production purpose. The hybrid cars are advantageous over the other cars because they are environmental friendly and do not produce pollutants as by-products. Another drawback of using hybrid cars is that it takes a lot of time to recharge; however, its environmental friendliness overcome this shortcoming.

What made hybrid cars such a success is the fact that it combines the strengths of both kinds of engines. It produces less pollution as compared to gasoline/diesel cars. It is more cost effective, and gives better performance than the electric cars. The components of a typical hybrid car are: ? Fuel tank for the gasoline engine; ? A small but efficient gasoline engine; ? An electric motor/generator; ? A set of batteries that act like a fuel tank of an electric engine; ? Transmission system, which turns the wheels.

There are two types of hybrid cars: parallel and series. A parallel hybrid car can use either the gasoline engine or the electric motor to turn the transmission; while in a series hybrid car, only the electric motor can generate transmission to the wheels. The gasoline engine is used to charge the batteries of the electric motor only.

The various features that make hybrid cars such a success in terms of efficiency are small and efficient engines; regenerative breaking that allows the electric motor to act as a generator, which charges the batteries as the engine slows down; periodic engine shut-off that restarts when the gear is put back hence, saving fuel; advanced aerodynamics which reduce the drag co efficient; LLR tiers and last but not the least, light weight materials to reduce the overall weight of the car.

There are various features which make hybrid cars a success including, its efficiency being a small car, and efficient engine. This car also features regenerative breaking that makes the electric motor to perform as a generator. Whenever the engine slows down, the batteries are charged. Hybrid cars also save the fuel consumption, and the advanced aerodynamics reduces the drag co-efficient and LLR tiers. Moreover, the light weight minerals decrease the overall weight of the car. Hybrid cars protect our environment and hence, are also known as green cars. The advanced technology installed in this car makes it a highly-designed car for future that fulfils the needs of consumers. - 21392
