JVS's Compression Release Brake Technology

Increasing productivity with safer, faster trip times

The Jacobs’ compression release brake reduces foundation brake load by turning your diesel engine into a power-absorbing air compressor.

Jacobs' High Power Density system rendering

100% increase in braking power with conventional or alternative fueled engines

Jacobs High Power Density® technology offers reduced package and mass as compared to other vehicle retarding solutions such as hydraulic driveline retarders. This results in increased payload by providing all the vehicle retarding performance you need from the engine.

Jacobs Vehicle Systems Cylinder Deactivation Technology

For improved fuel economy & exhaust thermal management

Jacobs’ Cylinder Deactivation (CDA) helps achieve NOx standards, extended low load cycles, and stringent fuel economy standards.
