An auxiliary power unit (APU) is a piece of equipment installed on a truck that provides energy for various functions when the main engine is off. Typically, an APU consists of a small engine and a generator that provide power for heating, cooling, and running appliances. APUs are becoming increasingly important in the trucking industry, helping drivers stay comfortable and saving companies money.
Holdwell aims to define what is an APU in a truck, explore its different types, and discuss the advantages and disadvantages of using APU in trucks. By understanding these aspects, you'll have a clear understanding of why APU are so important in truck parts.
What is an APU?
An Auxiliary Power Unit, or APU, is a small but mighty device that sits in a truck. It provides power when the main engine isn't running. Think of it as a mini power station for your truck.
APUs work independently from the main engine. They can keep things running even when the truck is parked. This means drivers can enjoy comfort and use their devices without burning extra fuel.
Key Components of an APU
-
Engine: The heart of the APU is its engine. It can run on diesel, gasoline, or propane. This small engine generates the power needed for all other functions.
-
Generator: The engine powers a generator. This part turns mechanical energy into electrical power, which the truck can use.
-
Fuel System: APUs need fuel to run. The fuel system stores and delivers the right amount of fuel to keep the APU working smoothly.
-
Cooling System: Like any engine, APUs generate heat. The cooling system helps keep everything at the right temperature to prevent overheating.
-
Control Panel: Drivers manage the APU through a control panel. This user-friendly interface lets them adjust settings and monitor the unit's performance.
These parts work together to provide a reliable power source for trucks. APUs help drivers stay comfortable and productive, even when they're not on the move.
Not all APUs are the same. Truckers have several options when choosing an APU. Here is a brief overview of the main types on the market:
A. Diesel-powered APU
Diesel-powered APUs use the same fuel as most truck engines. Diesel APUs are very efficient and reliable and can handle high power demands. However, they can be a bit noisy and will consume the truck's fuel.
B. Battery-powered APU
Battery-powered APUs use stored electricity to run. They are quiet and great for overnight parking, but you need to charge them to use them.
How do I choose the right APU?
Choosing the right APU depends on your priorities - whether it's efficiency, environmental impact or convenience. To make it easier for you to make a choice, Holdwell has put together a table for you. Please refer to the table to make the most appropriate decision.
Benefits of using an APU
A. Cost savings:
Using an APU, you can significantly reduce the idling time of the truck engine, and the APU takes over to keep the engine running. APUs consume much less fuel than the main engine, which can help save a lot of fuel on long-distance transportation
B. Reduce engine wear
Reduced idling means less unnecessary wear on the main engine, which can extend engine life and reduce maintenance
C. Improve driver comfort and rest quality
APUs can control the temperature of the cab and power basic facilities, providing a more comfortable rest environment. Helping drivers get better rest, which is crucial to safety.
Will you also be amazed by the benefits of using an APU? APU is a win-win situation. They are good for driver comfort, company profits, and the environment. No wonder they are becoming more and more popular in the trucking industry!
In conclusion, Auxiliary Power Units (APUs) play a vital role in modern trucking and have become an integral part of the modern trucking industry.
Holdwell offers APU replacement parts from major well-known brands such as Rigmaster APU, ThermoKing APU, Carrier Transicold APU, etc. Helping truck drivers to efficiently maintain their APUs, maximize their benefits and ensure consistent, reliable performance on the road.
