Jacobs Vehicle Systems Press Release / October 22, 2015

Jacobs Vehicle Systems, the world’s leading manufacturer of diesel and natural gas engine retarding systems and valve actuation mechanisms, announces that it has launched an engine brake for the DAF MX-11 Euro 6 in North America.

The new Jacobs engine brake was the result of more than three years of collaboration between Jacobs and Paccar engineers to provide an integrated engine brake solution which minimizes weight and space while providing market leading braking power.

The MX-11 engine brake delivers up to 319 kW (427 hp) of braking power at 2100 rpm and 208 kW (278 hp) at 1500 rpm, which is the most fuel efficient engine speed for maximum performance of the vehicle.

“This is a very exciting time for Jacobs Vehicle Systems. The successful launch of the new MX-11 engine brake is a terrific demonstration of the benefits resulting from joint engineering between Paccar and Jacobs. This fully integrated design optimizes the brake into the smallest and lightest package while still delivering benchmark performance,” stated Joao Cullen, VP of Engineering.

The MX-11 Jacobs engine brake is currently available in the European market on the new DAF Euro 6 CF and XF Series trucks, and will be launched in North America on Kenworth and Peterbilt trucks in January 2016.
