An alternative fuel vehicle is a vehicle that darts on a fuel other than "traditional" petroleum fuels such as petrol or diesel; and any method of powering an engine that does not involve exclusively petroleum.
An important thing about alternative fuel used in these vehicles is that, its materials can be found anywhere, counting your own garden as well. Some materials comprise old frying oil, used vegetable oil, plant or animal wastes and other reprocessed materials (they undergo processes definitely).
Working on alternative power systems for vehicles has become a high precedence for governments and vehicle manufacturers around the world as they have to restrict greenhouse emissions. Following mentioned are some types of alternative-fuel vehicles:
Solar vehicleA solar vehicle is an electric vehicle motorized by solar energy attained from solar panels on the car. The panels utilize photovoltaic cells, which transfer solar energy into electrical energy. Most of these vehicles however have lingered as experimental model cars used for exhibition and advertising purposes, often sponsored by government. Actually solar vehicles are made for the purpose of solar car races as they are noiseless and fairly fast and can travel over long distances. The chances of existence of solar powered vehicles have largely advanced as examiners persist to introduce more realistic and reliable electric motors, control systems, battery power and highly developed electronics.
Compressed-air vehicle A compressed-air vehicle is motorized by an air engine, using compressed air, which is stored in a tank. A compressed vehicle, to drive their pistons uses the expansion of compressed air instead of combining fuel with air and burning it in the engine and an inbuilt compressor in it initiates its operation of compressing more air when the car is driven at higher speeds in order to give the vehicle an additional push. The design of the car intends to make it lighter, make it likely to stay fuel proficient and move rapidly for a longer duration.
Liquid nitrogen vehicles A liquid nitrogen vehicle is motorized with liquid nitrogen which is stored in a tank. The engine to perform its operation heats the liquid nitrogen in a heat exchanger which extorts heat from the ambient air and utilizes the resulted pressurized gas to function a piston or rotary engine.
Liquid nitrogen is recommended as an alternative to liquid hydrogen in some transportation means and also as a mode of locally amassing energy detained from renewable sources. In hybrid systems, liquid nitrogen driving force can also be integrated, for instance- fuel tanks to recharge the battery and battery electric driving force.
