What Motor Is in a Semi Truck?

Semi-trucks, otherwise known as big rigs or 18-wheelers, are some of the most iconic vehicles on our roads. These large trucks are used for a variety of purposes, from hauling goods to transporting livestock.

But what powers these giant machines? The answer is a powerful motor.

A semi truck motor typically has an engine capacity ranging anywhere from 400 to 800 horsepower. Many modern semi trucks are powered by diesel engines, which are known for their fuel efficiency and durability. Diesel engines have become increasingly popular in recent years due to their low emissions and improved performance.

The most common type of semi truck motor is the Cummins N14 engine. This engine was first introduced in 1988 and has since become one of the most reliable and efficient engines on the market. It is a four-stroke diesel engine which produces up to 500 horsepower and 1,850 pound-feet of torque.

The Cummins N14 engine is also equipped with advanced features such as electronic fuel injection, turbochargers, and exhaust gas recirculation systems. These features help the engine run more efficiently while reducing emissions significantly.
