Horse-drawn carriages were commonly used in old age to carry passengers. The first steam engine was designed in the 18th century, but it failed. People had to wait until the 20th century, when ordinary piece auto
were replaced by four-wheelers.
Vehicles have changed the world and created complex road and highway systems. The second major problem was the power or fuel system used to drive the vehicle. There is also a need to explore alternative energy systems for automobiles.
Modern automobiles are primarily powered by gasoline internal combustion engines mounted at the front of the vehicle. The engine uses gasoline to generate electricity, and this electricity is transmitted to all four wheels. Diesel fuel is another alternative to electric vehicles. Regular cars, also known as autos, use gasoline to carry passengers, while large cars designed to carry more passengers use a diesel fuel system.
As the days passed, the engine became more powerful and more fuel was used in the process as a result. Gasoline internal combustion engines are a source of air pollution and were considered the main cause of global warming. Also, fuel costs are no longer manageable in modern times.
With the high prices of gasoline and diesel, an alternative to the automotive power system was needed. Alternative fuel engines were developed in the United States in 2002 using liquefied petroleum gas (LPG) and compressed natural gas (CNG).
Alternative power systems have proven to be an ideal and cheaper option compared to gasoline internal combustion engines. The alternative energy system uses the same infrastructure, with some changes, and many vehicles around the world have started using this alternative energy system. LPG and CNG are also inexpensive and easy-to-fill options, as they were previously filled with gasoline and diesel.
In the past, steam engines were more common than gasoline engines. It also has the advantage of low harmful emissions. At the same time, they were less efficient than gasoline engines and were therefore ignored after the introduction of gasoline engines. Steam engines may be the best alternative energy system for automobiles, so much research and experimentation has been done to improve their performance.
Battery electric motors are another alternative power system for cars. Electric motors can be produced efficiently and at high speed. Many local vehicles prefer these engines, but they are limited to short distances. Electric vehicles cannot be used for long-distance travel due to the limited batteries that power the motors. Solar cells may be an alternative, but they are not yet a successful option. Fuel cells are promised, but they are more expensive and intolerable to the general public.
Much research has been done to use fuels derived from plant materials. Sunflower seed oil powered biodiesel test cars have been tested and are expected to be the best alternative power system for cars.
