Which fraction obtained from crude oil is primarily used as fuel for lorries?

The fraction from crude oil that is primarily used as fuel for lorries is diesel. Diesel fuel is specifically designed for use in diesel engines, which are commonly found in larger vehicles such as lorries and trucks due to their efficiency and torque characteristics.

Diesel is heavier than gasoline and has a higher boiling point, which makes it suitable for the high-compression ratios in diesel engines. This fuel provides better fuel economy and is able to power larger loads, making it the preferred choice for commercial transportation.

Other fractions like gasoline are more volatile and are primarily used in lighter vehicles, while refinery gases and kerosene serve different purposes; refinery gases are utilized for heating and energy, and kerosene is often used in jet fuel or heating applications rather than in road transport vehicles like lorries.
