GREEN CAR TECHNOLOGY: THE CURRENT WAVES
Green car technology is a method that is adapted in an attempt to save our precious environment by avoiding the usage of fossil fuels that makes the environment polluted. Over the years researchers have been experimenting with the technology that facilitates the use of electrically maintained cars and are also trying to find a substitute to the existing vehicles that use fossil fuels. Earlier this century, it was quite shocking to know that our planet was on its threshold with respect to greenhouse effect. The main reason behind this was known to be the usage of fossil fuels which in turn contributed to the depletion of ozone layer thereby increasing greenhouse effect. With an attempt to reduce this menace, car manufacturers across the globe began manufacturing greener ecologically aware cars.
Presently in this century, the vehicles have been manufactured with a hybrid engine which is nothing but a conservative motor engine, which is combined with the usual electric engine. These are capable of toggling between power of an electric motor and the ignition engine. With normal speeds, the car is powered by electric motor and at high speeds; the ignition engine powers the vehicle. Here are a few green technology cars presently available:
Electrically powered vehicles have gained a lot of popularity in the recent past as they possess an electric motor, which is powered with battery packs and these packs are a combination of Nickel metal-hydride or Lithium-ion, which are charged with a connection to main power supply typically charged for an entire night. Also, these electric cars have iterative braking system due to which the batteries are charged when brakes are applied
Currently, hybrid cars use both the electric motors and petrol engines. The electric motor is powered by the batteries, which are charged and useful at lower speeds, while the petrol engine possesses a small unit which powers it during high speeds thereby allowing this engine to function only at optimum speed. Also, the renewable energy sources like rapeseed; sunflower or soybean oil is used to produce biodiesel, wherein the carbon dioxide gas emitted is neutralized as it is absorbed by the fuel crop, which facilitates its growth.
Ethanol, which is a sugarcane product, contains high octane content, which increases engine performance and is broadly used in Europe wherein flexi-fuel vehicles are developed on Ford, Saab etc. Liquefied Petroleum Gas (LPG) contains propane and butane, which produces less CO2 than petrol and diesel. The internal engine can be modified because of which the vehicle can use petrol or LPG.
Fuel cells are conversion devices which provide energy from electrochemical reaction and electricity can be continually produced with the flow of reactance. However, this technology is proven to be expensive. Another fossil fuel is the compressed natural gas found underneath the earth surface, which also produces less CO2 gas and this gas is compressed in the cylinder and mixes well with the air before combustion, thereby making it an efficient fuel.
However with the advent of the green technology, environment awareness is being fast spread to various industries and manufacturers thereby creating efficient business opportunities to the investors. This awareness has led to the creation of vital engines with most advantageous performance and is also eco friendly. Green car technology has revolutionized the vehicle manufacturing process thereby saving our planet Earth to a certain extent.
