BLOOMFIELD, CT, USA – Jacobs Vehicle Systems, a worldwide manufacturer of engine retarding and valve actuation systems for the commercial vehicle industry, has upgraded the company’s engine brake on model-year 2021 PACCAR MX-11 heavy-duty diesel engines. The electronically controlled engine brake now includes a new high-flow solenoid to facilitate faster, smoother gear shifting, resulting in simplified and smoother vehicle operation, as well as fuel consumption improvements.

“The high-flow solenoid allows for faster engine brake system activation, which when coupled with an engine brake-assisted shifting strategy, will reduce the time it takes for the transmission to shift gears,” said Gabe Roberts, Jacobs’ director of product development. “Not only is this good for the powertrain and for fuel economy, but drivers will also enjoy a smoother driving experience in addition to best-in-class compression release engine brake performance.” 

Added Steve Ernest, vice president of engineering & business development for Jacobs, “Our newest Jake Brake^® adds important enhancements to the popular MX-11 engine and represents the latest example of our ongoing collaboration with engine manufacturers around the world to improve the efficiency and performance of commercial vehicle diesel engines.”

Jacobs’ newest engine brake is manufactured at the company’s headquarters in Bloomfield, Conn., and delivered to PACCAR engine plants in Columbus, Miss.; the DAF engine plant in Eindhoven, the Netherlands; and Ponta Grossa, Brazil.
