Peterbilt trucks are renowned in the heavy-duty truck industry for their durability, reliability, and advanced engineering. This American brand has a storied history and has become a symbol of quality and excellence in the trucking world.

The charge air cooler in a Peterbilt truck plays a crucial role in the engine performance. It is also known as an intercooler. Its primary function is to cool down the hot compressed air from the turbocharger before it enters the engine combustion chamber. Cooler air is denser, which means more oxygen for combustion, leading to better engine efficiency and power output.

Similar to a radiator, the charge air cooler consists of a network of tubes and fins, which the hot compressed air passes through. As it travels through this network, ambient air flows over the exterior of the tubes, cooling down the compressed air inside. This process helps preventing engine overheating and ensuring optimal engine performance.
