1. Gasoline: Gasoline is the most common fuel used in automobiles and is derived from crude oil. It is a mixture of hydrocarbons that are ignited in the engine to produce power. Gasoline engines are typically used in passenger cars, trucks, and motorcycles.
2. Diesel: Diesel is another fuel derived from crude oil and is commonly used in trucks, buses, and other heavy-duty vehicles. Diesel engines are more efficient than gasoline engines but also produce more emissions.
3. Natural Gas: Natural gas is a fossil fuel that is composed primarily of methane. It is often used as a fuel in vehicles, especially in fleet vehicles such as buses and taxis. Natural gas vehicles produce lower emissions than gasoline or diesel vehicles.
4. Biodiesel: Biodiesel is a renewable fuel produced from plant oils, animal fats, or waste cooking oil. It can be used in diesel engines without any modifications and is considered a cleaner alternative to petroleum diesel.
5. Hydrogen: Hydrogen is a clean-burning fuel that can be used in fuel cell vehicles. Hydrogen fuel cells produce electricity through a chemical reaction between hydrogen and oxygen, with water vapor as the only emission. However, hydrogen fuel cell vehicles are still relatively rare due to the lack of infrastructure for hydrogen fueling.
