What engines do semi trucks have?

May. 20, 2022

Trucks, also known as cargo vehicles and generally referred to as lorries, are vehicles that are primarily used for the transport of goods or sometimes for towing other vehicles and belong to the category of commercial vehicles. They can generally be divided into heavy-duty and light-duty vehicles according to their weight. The vast majority of vans are powered by diesel engines, and since their introduction into passenger cars in the late 1980s, oil engines have become a staple of the 'work truck' industry. Diesel engines are the common choice for commercial trucks. Diesel is not petrol; unlike conventional internal combustion engines, diesel engines rely more on a very high compression ratio to ignite the fuel. This greatly improves fuel efficiency compared to its petrol counterpart of the same size. Diesel engines also produce twice the torque of petrol engines and rev considerably lower, making them ideal for heavy trailer work.

Performing well at low engine speeds is part of what helps improve efficiency and is key to the longevity of these systems. Hard-working petrol engines operate at high engine speeds and huge internal forces, leading to premature component wear and failure. While regular maintenance on diesel engines can be more frequent and expensive than on petrol engines, it is not uncommon for good diesel vehicles to travel over 400,000 miles because they do not need to work as hard to get significantly better results.

Diesel truck owners tend to be passionate about their brand, and for good reason.
