Eco-Friendly Cars: Today’s biggest problem is Global warming, the increasing air pollution day by day letting it to reach at top. Air pollution occurs when harmful or excessive quantities of substances including gases, particulates, and biological molecules are introduced into Earth’s atmosphere.
It may cause diseases, allergies and also death of humans; it may also cause harm to other living organisms such as animals and food crops, and may damage the natural or built environment. Human activity and natural processes can both generate air pollution.
Vehicles are playing a major role in increasing the air pollution, with increased world population number of vehicles has also increased and the gases and smog emitted by
them contributing to the global warming. Most of the vehicles are now run either on petrol and diesel emitting greenhouse gases like carbon dioxide (CO2), methane (CH4) and nitrous oxide, Of the total greenhouse gas emissions from transport, over 85% are due to CO2 emissions from road vehicles. The transport sector is the fastest growing source of greenhouse gases. It’s a high alert for all of us and peak time to make efforts to reduce its level otherwise we all are well aware about the worst consequences.
Green Vehicles are the solution to overcome from this issue at certain level. A green vehicle, or clean vehicle, or eco-friendly vehicle or environmentally friendly vehicle is a road motor vehicle that produces less harmful impacts to the environment than comparable conventional internal combustion engine vehicles running on gasoline or diesel, or one that uses certain alternative fuels.
Eco-friendly cars are flux fuel models, hybrid and electric cars. Hybrid and electric cars are playing a major part in reducing the environmental pollution with lesser fuel consumption.
One of the biggest advantage of hybrid car over gasoline-powered car is that it runs cleaner and has better gas mileage which makes it environmentally friendly. A hybrid vehicle runs on twin powered engine (gasoline engine and electric motor) that cuts fuel consumption and conserves energy.
The term “electric vehicle” refers to any vehicle that uses electric motors for propulsion, while “electric car” generally refers to highway-capable automobiles powered by electricity.
Most often, the term “electric car” is used to refer to battery electric vehicles.
Compressed Air Cars:
Compressed air vehicle that uses a motor powered by compressed air. The car can be powered solely by air, or combined with gasoline, diesel, ethanol, or an electric plant with regenerative braking.
A zero-emissions vehicle, or ZEV:
A zero-emissions vehicle or ZEV is a vehicle that emits no exhaust gas from the onboard source of power. Harmful pollutants to the health and the environment include particulates (soot), hydrocarbons, carbon monoxide, ozone, lead, and various oxides of nitrogen. Although not considered emission pollutants by the original California Air Resources Board (CARB) or U.S.
Environmental Protection Agency (EPA) definitions, the most recent common use of the term also includes volatile organic compounds, several air toxics, and global pollutants such as carbon dioxide and other greenhouse gases.
Liquid Nitrogen Vehicles:
A liquid nitrogen vehicle powered by liquid nitrogen, which stored in a tank. Traditional nitrogen engine designs work by heating the liquid nitrogen in a heat exchanger, extracting heat from the ambient air and using the resulting pressurized gas to operate a piston or rotary motor. Vehicles propelled by liquid nitrogen demonstrated, but not used commercially.
One such vehicle, Liquid Air demonstrated in 1902 even less polluting than electric vehicles, as the vehicle and its components can be made more environmentally friendly. As a part of the earth it is our responsibility to take care of mother earth, so we need to take appropriate steps.
