TECHNOLOGIES

Proven solutions on the road around the world

From inventing compression release technology to developing next-generation valve trains and advanced braking systems, we are continually raising the levels of performance—for power, fuel economy, and reduced emissions—that heavy-duty commercial vehicles can achieve.

Proven technologies around the world

Increasing productivity with safer, faster trip times

Compression Release Engine Brake

The Jacobs’ Compression Release Engine Brake reduces foundation brake load by turning your diesel engine into a power-absorbing air compressor.
100% increase in braking power with conventional or alternative fueled engines

High Power Density®

Jacobs High Power Density® technology is the lightest, most cost-effective, high power vehicle retarding technology available.
For improved fuel economy & exhaust thermal management

Cylinder Deactivation

Jacobs’ Cylinder Deactivation (CDA) helps achieve stringent NOx and fuel economy standards, even during extended low load cycles.
For exhaust thermal management, engine performance and emissions

2-Step Variable Valve Actuation

Jacobs’ 2-Step VVA meets future transient emissions and fuel economy targets with minimal change to the base engine and aftertreatment system.
Smooth start-up and shutdown

Active Decompression Technology®

Jacobs Active Decompression Technology® (ADT®) eliminates engine-induced cabin vibration to improve engine start-up/shutdown.
Meeting future emissions and fuel economy targets

Variable Valve Actuation

Jacobs’ Variable Valve Actuation and control systems help achieve performance, fuel economy and emissions targets.
Higher performance than exhaust brakes while keeping valve train loading low

Bleeder Brake

Our integrated bleeder brake design allows for Jake Brake® technology for engines with packaging and load constraints.
More slowing power from your horsepower

Exhaust Brake

The Jacobs’ Exhaust Brake increases braking power and extends the life of foundation brakes.
Enabling the use of a hydraulic lash adjuster & an engine brake

Lashless Valvetrain with Engine Braking

Jacobs Fulcrum Technology improves performance and efficiency while eliminating the need to adjust valve lash.
