What Does the Turbo Do in a Semi Truck?

Semi truck turbos are one of the most important components of any semi truck’s engine. The turbocharger, or turbo, is a device that increases the power and efficiency of a diesel engine.

It does this by forcing more air into the engine, allowing it to burn fuel more efficiently and thus providing more power.

A semi truck’s turbo is typically located on the side of the engine block and is connected to a turbine wheel. The turbine wheel spins when exhaust gases pass through it, creating a vacuum that pulls in additional air from outside the engine. This additional air increases the amount of oxygen available for combustion and allows for more fuel to be burned in each cylinder.

The turbo also helps reduce exhaust emissions by providing cooler air to burn with the fuel. This cooler air reduces the amount of unburned hydrocarbons in the exhaust gases, which helps reduce harmful emissions such as carbon monoxide.

In addition to reducing emissions, semi-truck turbos can also increase fuel efficiency by up to 20 percent. By forcing additional air into each cylinder, more fuel can be burned with every stroke of the piston. This additional power allows semi trucks to travel farther on less fuel.

Conclusion:

The turbocharger plays an integral role in a semi truck’s engine performance and efficiency. It increases power output by forcing additional air into each cylinder, allowing for more fuel to be burned in each stroke of the piston and helping reduce harmful emissions from exhaust gases. Additionally, it improves fuel efficiency by up to 20 percent – making it an essential component for any modern semi truck.
