Diesel Fuel: This is the most common fuel for heavy-duty trucks, like semi-trucks and delivery trucks. It's known for its high energy density and efficiency.
Gasoline: Smaller trucks, like pickup trucks and vans, often run on gasoline. It's more readily available than diesel, but less efficient.
Biodiesel: This is a renewable fuel made from vegetable oils or animal fats. It can be blended with diesel fuel, providing a cleaner-burning alternative.
Compressed Natural Gas (CNG): This is a natural gas that's compressed and stored in tanks. It's cleaner-burning than diesel or gasoline, but has limited range and requires specialized fueling infrastructure.
Liquefied Natural Gas (LNG): Similar to CNG, but the natural gas is cooled to a liquid state, allowing for higher storage density and longer range.
Electricity: Electric trucks are becoming increasingly popular, especially for short-haul applications. They run on batteries that need to be recharged, offering zero emissions.
Hydrogen: Hydrogen fuel cells can power trucks, producing only water as a byproduct. This technology is still in its early stages of development.
The specific fuel used by a truck will depend on its specific application and the preferences of the owner.
