The new Handtmann supercharge air module was developed for a new generation of diesel engines. These engines use the supply of high-pressure and low-pressure exhaust gas to reduce nitrogen oxide emissions. Cooling the supercharge air also increases the power density.

The supercharge air module introduces the fresh air flow into the cylinder head together with the high-pressure and low-pressure exhaust gas. An integrated supercharge air cooler provides the required cooling of the fresh air. In order to achieve an optimal ratio of nitrogen oxide and soot particle emissions in each operating state and to comply with exhaust gas standards, uncooled high-pressure exhaust gas is added at certain operating points. The EGR valve regulates the flow rate.
