ENGINE | 642.896/992 in MODEL 906 |
115 | Charge air cooler |
D09.41-1135-10
Location
The charge air cooler is located at the bottom crosswise in front of the engine cooler.
Task
The charge air cooler cools down the charge air heated up by compression. This improves the cylinder charge level and reduces the formation of nitrogen oxide (NOx) thanks to lower exhaust gas temperatures.
Body
The charge air cooler is a heat exchanger in crossflow format.
Function
The charge air is warmed up by compression of the air drawn into the turbocharger. The charge air gives up its heat to the air stream passed through the charge air cooler, which is located directly downstream of the turbocharger.
