What Is APU in a Semi Truck?

A semi-truck, also known as an articulated lorry, is a large truck made up of two parts that are connected with a joint. The two parts are the tractor and the trailer. The tractor is the part of the truck that is driven by a driver, while the trailer is pulled behind it and filled with cargo.

The Advanced Processing Unit (APU) in a semi-truck is an on-board computer system that helps manage fuel and engine performance. This computer system constantly monitors engine temperature, fuel efficiency, speed, RPMs and other important performance metrics to keep the truck running efficiently.

The APU also helps reduce emissions by automatically turning off the engine when it’s not in use. This conserves fuel and reduces environmental impact.

Additionally, the APU can be used to adjust transmission settings based on terrain or load weight. This ensures optimal performance in any situation.

Another key function of the APU is its ability to monitor driver behavior. The system keeps track of how many hours a driver has been on duty and can alert them if they are driving too fast or if they need to take a break.

Finally, some semi-trucks come equipped with an APU that allows for remote diagnostics and maintenance scheduling. This allows fleet managers to stay up-to-date on maintenance needs without having to send out technicians for every minor issue.

In conclusion, Advanced Processing Units (APUs) in semi-trucks are powerful computers systems that help manage engine performance and increase fuel efficiency while reducing emissions. They also enable fleet managers to monitor driver behavior and remotely diagnose maintenance issues for optimal performance and safety on the road.
