Jacobs adds optimized engine brake for the Cummins X15

Nov. 2, 2016

Jacobs Vehicle Systems announces the optimized engine brake for the 2017 Cummins X15 engine.

Jacobs’ and Cummins’ engineers have once again raised the bar by improving the already industry-leading performance of the integrated Jake Brake for the 15-liter engine. Launching now, the model year 2017 X15 engine offers the highest level of engine braking performance for heavy duty engines in North America.

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 1,700 RPM, compared to that of the 2010 ISX15. At a typical engine speed of 1,500 RPM, drivers can now rely on 450 horsepower 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 600 horsepower of braking at 2,100 RPM. The X15 braking performance continues to be best-in-class for heavy-duty engines in North America.
