What are the three main fuels?

The three main fuels for automobiles are gasoline, diesel, and natural gas (including liquefied natural gas LNG and compressed natural gas CNG). Gasoline is a light petroleum fraction with good volatility and flammability, suitable for most light vehicles and sedans, as it can quickly start the engine and maintain stable operation. Diesel has a high energy density and excellent anti-knock performance, commonly used in heavy-duty trucks, engineering vehicles, and some SUVs, providing strong power and excellent fuel economy. As a clean fuel, natural gas produces significantly fewer pollutants during combustion than traditional fuels, and is widely used in public transportation and taxi sectors, effectively reducing environmental impact. The choice of different fuels needs to consider factors such as vehicle engine type, usage scenarios, and environmental protection requirements. For example, gasoline vehicles are suitable for daily urban commuting, diesel vehicles are more suitable for long-distance heavy loads, and natural gas vehicles are one of the preferred options for environmentally friendly travel.
