How Does a Semi Truck Engine Work?

Semi-trucks are an integral part of the transportation industry, as they transport goods and materials from one place to another. To do this effectively, semi-trucks need a powerful engine that can drive them long distances with heavy loads. But just how does a semi-truck engine work?

The heart of a semi-truck is its engine, which is typically a diesel engine. Diesel engines are known for their durability, reliability, and efficiency.

They work by compressing air and fuel together, then igniting it to create power. This process is known as the four-stroke cycle.

The first stroke of the cycle is the intake stroke. During this stroke, air and fuel are drawn into the cylinder. The second stroke is the compression stroke during which the air and fuel are compressed by the piston in order to increase their temperature and pressure.

The third stroke is called the power stroke. During this stroke, a spark plug ignites the compressed air and fuel mixture causing it to expand rapidly and generate power which drives the piston down. The fourth and final stroke is called the exhaust stroke during which exhaust gases are expelled from the cylinder.

Conclusion:
A semi-truck engine works by compressing air and fuel together then igniting it using a spark plug to produce power in a four-stroke cycle. This process is what propels these large vehicles forward with heavy loads across long distances, ensuring that goods and materials make it to their destination safely and on time.
