Diesel powertrain

The diesel engine remains an indispensable cornerstone for heavy-duty freight transport and demanding off-highway applications. To meet increasing demands for economic viability and eco-friendliness, advanced injection technology is crucial. The sophisticated common-rail system forms the technological basis for metering fuel with high precision and extreme efficiency.

Our developments range from flexible solenoid and piezo systems to modular concepts for trucks and robust technologies for heavy large engines. We also serve specific global markets with proven unit-pump as well as mechanical systems. Through this technological breadth, we increase the efficiency and reliability of commercial vehicles worldwide.
