What Are Hybrid Cars?
The current economic crisis has caused a great rise in the prices of gasoline, and it is becoming very unaffordable for many people. The car owners are also greatly concerned about global warming, and green house effect issues. Therefore, for erasing these worries of people, the auto industry has introduced hybrid cars.
A Hybrid car is a vehicle that uses two or more different energy sources to run the engine. The most frequently used term for such vehicles is HEVs (Hybrid Electric Vehicles), which use an internal combustion engine and electric motors. Apart from electric motors, other energy sources that can be used in a hybrid car are Hydrogen, compressed air, liquid Nitrogen, wind, solar energy and even coal, wood and other solid combustibles.
The most common thing that pops up in our mind is that if we are so much concerned about the issue of pollution then why do not we switch to electric cars? Why do we need to hybridise a car for this purpose? The simple answer to this is that they do not meet the certain requirements if you want to drive on the national high way. These requirements includes that the car should run at least 300 miles before refuelling, it has the ability to be refuelled easily, and it can maintain an average speed near to those of the other vehicles on the road.
Many benefits of an electric car are there, such that they do not cause any pollution, and they do not require any gasoline to run on. On the other hand, they do have some disadvantages such as their recharging is time-consuming; they move with a comparatively sluggish pace, and require a recharge after a maximum of 100 miles. However, gasoline engines meet all these requirements very easily, but they are very costly because of the expensive fuel, and it is a biggest contributor to the global warming.
Hybrid car is mixture of these two types of engines, by taking up the positive aspects of both. In this manner, it has been able to achieve increase in mileage, and at the same time has been successful in eliminating the side effects of the gas-powered engine.
A hybrid car has a gasoline engine, which is smaller than ordinary cars, uses advanced technologies to reduce emissions and increase efficiency, a fuel tank, which is an energy storage device for the gasoline engine, a sophisticated electric motor, which can act as a motor (to draw energy from the batteries to accelerate the car), as well as a generator (to slow down vehicle and return energy to the batteries). Apart from that, HEVs include transmission and batteries which act as a storage device for the electric motor.
The engines of a Hybrid car can be configured in a parallel or series setting. In parallel hybrid, both the engine and the electric motor turn the transmission at the same time. The fuel tank supplies gasoline to the engine. At the same time, the batteries supply power to the electric motor. In series hybrid, the gasoline engine does not provide energy directly to the vehicle. It rotates the generator, and the generator can either charge the batteries or energize the electric motor that drives the transmission.
The major objective of the invention of Hybrid cars were to improve mileage and reduce toxic emissions, and these objectives are very much being met by our HEVs. The grams/mile limit, standardized by most of the countries, is being efficiently met by these vehicles, and the investment is also profitable, considering the high rates of gasoline. - 21393
