Diesel is a type of fuel commonly used in diesel engines, which are found in various vehicles and machinery. It is derived from crude oil through a refining process and is known for its high energy density. Diesel fuel is less volatile than petrol and is ignited through compression rather than a spark. It is widely used in trucks, buses, trains, and heavy machinery due to its efficiency and torque. Diesel engines are known for their durability and fuel economy, making diesel fuel a popular choice for long-haul transportation and industrial applications.
