From inventing compression release technology to developing next-generation valvetrains and advanced engine braking systems, we are continually raising the levels of performance—for power, fuel economy, and reduced emissions—that commercial vehicles can achieve.
Since 1961, Jacobs has led the way in designing, testing, and manufacturing high-performing engine brakes for engine OEMs around the world. From Exhaust Brakes to High Power Density® Engine Brakes, Jacobs has a solution for your engine and vehicle application.
Jacobs High Power Density® technology is the lightest, most cost-effective, high-power vehicle retarding technology available.
The Jacobs Compression Release Engine Brake reduces foundation brake load by turning your diesel engine into a power absorbing air compressor.
Jacobs Lashless Technology improves performance and efficiency while eliminating the need to adjust valve lash.
Jacobs Bleeder Brake technology offers a braking solution for applications on smaller displacement engines when cost and packaging is a consideration.
Jacobs Exhaust Brake® provides additional vehicle braking power by restricting the flow of exhaust gases and increasing back pressure to the engine.
Jacobs advanced valvetrain technologies help OEMs around the world meet regulations by optimizing the engine and aftertreatment systems to improve emissions, fuel economy, and exhaust thermal management.
Jacobs’ Cylinder Deactivation (CDA) helps achieve stringent NOx and fuel economy standards, even during extended low load cycles.
Jacobs 2-Step VVA meets future transient emissions and fuel economy targets with minimal change to the base engine and aftertreatment system.
Jacobs Variable Valve Actuation and control systems bring you an entire suite of solutions to help achieve performance, fuel economy, and emissions targets. This can range from fully-flexible valvetrains to very specific, targeted variability.
Jacobs ADT® allows drivers to experience smoother start-ups with faster starting times and engine shutdown without engine-induced cabin vibration.
