A significant milestone has been reached by Jacobs Vehicle Systems, the world's leading manufacturer of diesel and natural gas engine retarding systems and valve actuation mechanisms, with the sale of its one millionth engine brake for Daimler Trucks' heavy duty engine platform (HDEP). Daimler Trucks has relied for more than 10 years on the braking performance of the "Jake Brake®", an especially effective turbocharged compression release brake integrated into the engine and the engine control unit, which is both quiet and effective. Delivering an outstanding performance of up to 480 kW, the six-cylinder engine is available with displacement ranges between 10.7 litre and 15.6 litre and output levels from 240 kW to 480 kW.
