D934 A7 Diesel engine

The Liebherr diesel engine D934 A7 with 4 cylinders in inline-arrangement and a displacement of 7 liters has a maximum power of 200kW at 1,900 revolutions. Dynamic forces in a 4-cylinder engine are compensated for by a balance shaft. Therefore, the 4-cylinder engines from Liebherr have much lower vibrations and much smoother operation than comparable 4-cylinder engines. The engine features for regulated and unregulated markets identical performances, the same requirements for the machine‘s cooling system, and the same interfaces when installed. This enables the customer to use the same device design for different emission standards.
