What Size Engine Is in a Semi Truck?

A semi truck is a large, heavy-duty vehicle used for transporting goods and materials across long distances. It consists of a tractor unit and one or more trailers. Semi trucks are powered by engines that are significantly larger than those found in typical passenger vehicles.

Semi trucks typically use diesel engines, although some also use natural gas or even electric power.

The most common size engine found in a semi truck is the 13-liter engine. These engines are used in both on-highway and off-highway applications, and they provide excellent fuel economy while still offering plenty of power and torque for hauling heavy loads. The 13-liter engine is capable of producing up to 500 horsepower and 1,850 lb-ft of torque.

In addition to the 13-liter engine, semi trucks also come equipped with larger 15-liter engines. These engines are usually reserved for more powerful applications such as long-haul trucking or construction work. They can produce up to 600 horsepower and 2,050 lb-ft of torque, making them ideal for heavy-duty jobs that require significant amounts of power.

Conclusion:

In summary, the most common size engine found in a semi truck is the 13-liter engine which offers excellent fuel economy while still providing plenty of power and torque for hauling heavy loads. Larger 15-liter engines can be found in more powerful applications such as long haul trucking or construction work due to their increased capabilities.
