OVERVIEW

Fifty years ago, Clessie Cummins believed the diesel engine could be used on “both sides of the hill.” From that idea, the Jake Brake® engine brake was born.

About ten years ago, we began to test our theories of utilizing the precise valve actuations used in the engine brake on both sides of the hill. As a result, Jacobs variable valve actuation (VVA) was inspired. This research, combined with over forty years of precision valve actuation expertise, has yielded a NOx reduction solution which provides Internal Exhaust Gas Recirculation (IEGR) by altering engine valve lift. Jacobs IEGR reduces peak combustion temperatures and, therefore, reduces the formation of Nitrogen Oxides (NOx) to levels acceptable to meet upcoming emissions standards. Jacobs IEGR utilizes proven, reliable components and functional product designs mastered by Jacobs with its well-known Jake Brake® engine brakes. With over 3,000,000 engine brake systems sold and over 2.7 Trillion kilometers of road experience with precision valve actuation, the Jacobs IEGR system design is a solution you can trust.

Additionally, relative to other NOx reduction technologies, the Jacobs IEGR system is a very attractive option. Our system is compact, mounting directly to the engine overhead with minimal added weight and height. An engine packaged with Jacobs IEGR will require little to no modification without increasing radiator capacity. Engine serviceability is not compromised, and operation is transparent to the driver. If desired, an engine braking function can be integrated into the Jacobs IEGR product. When compared to other NOx reduction options, the cost of Jacobs IEGR system is very competitive.

Reliable, cost-effective NOx reduction technology is ready to help your engines meet upcoming tailpipe emissions for diesel engines. Turn to the experts the diesel industry has come to for over forty years. Turn to Jacobs.

At Jacobs Vehicle Systems, our philosophy is to continue to build on our foundation of partnership and legacy of trust with engine manufacturers. We will place no limitations on our thinking on their behalf. We will accept no restrictions in our planning for their success. We will constantly look for ways to serve them and their end-users by doing whatever it takes to provide the best in innovative and proven solutions

Customer and industry expectations are our baseline,and we intend to continue to exceed them with the most powerful and robust engine retarding and valve actuation technologies possible.
