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 MX-11 heavy-duty diesel engines from Paccar Inc.

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, according to the Bloomfield, Conn.-based company.

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



Parent company Altra Industrial Motion Corp. announced in February it entered into an agreement to sell its Jacobs Vehicle Systems business to Cummins Inc. for $325 million. — Transport Topics
