Jacobs Vehicle Systems announced the introduction of the optimized engine brake for the 2017 Cummins X15 engine.
“The 2017 X15 capitalizes on the optimization of the VGT and the braking cam to deliver approximately ten percent additional braking power at engine speeds under 1700 RPM, compared to that of the 2010 ISX15,” the company said. “At a typical engine speed of 1500 RPM, drivers can now rely on 450 HP of braking power to provide confidence and driver control while in traffic or descending a hill. Wıth a simple downshift to increase the engine speed, the engine brake in the X15 Performance Series will deliver a retarding force of up to 600HP of braking at 2100RPM. The X15 braking performance continues to be best-in-class for heavy duty engines in North America.”
“Cummins was Jacobs’ first engine brake customer in 1961. Over 55 years later, we continue to innovate through collaboration among our engineering teams using all engine systems available to maximize engine braking,” said Steve Ernest, vice president, Engineering and Business Development. “When the pioneers and global leaders of engine brakes combine efforts with world-class diesel engine designers, we drive constant innovation and evolution of technologies that deliver performance and value to the customer. With the Cummins X15, equipped with an integrated Jacobs Engine Brake, truckers will experience safer travel and the improved comfort they demand, while reducing the wear of foundation brakes, downtime and service costs.”
