4- According to fuel used

Petrol vehicle:-

The vehicles run on Petrol(gasoline) engines are highly used in the automotive sector.

All the Two-wheel vehicle comes with a petrol engine. And maximum car variants come with a petrol engine. It is a highly flammable fuel.

A petrol engine used a charge, which is the mixing of an Air-fuel mixture for propagating aflame with the help of a spark plug, which then used to produce pressure inside the combustion chamber which starts the cycle and runs the engine.

For example-TVS Jupiter, Maruti Suzuki Alto.

Diesel vehicle:-

These vehicles are runs on Diesel fuel, in diesel engines.

The diesel engines have a high compression ratio, therefore, there is no need for sparkplugs in this kind of engines.

The propagation of flame is done by injecting vaporized diesel in the high compressive air inside the combustion chamber, which starts the cycle and engine runs.

For example:- KIA Seltos HTE Diesel, Trucks and Buses.

Electric vehicle:-

With new technology Electric vehicles come in the Indian market.

ALL the Companies are now transferred from petrol/diesel to Electric vehicles in 2030.

  2. Power plant
  3. Transmission system
  4. Auxiliaries
  5. Controls
