2013 - 2018 Late 6.7L Cummins Exergy Injectors

With our background in OE development and manufacturing, we bring a unique perspective to the high-performance world. We know what features and specifications need to be to ensure proper function, we know how to produce them and how to verify they are correct. The verification process/equipment we use is very untypical of a standard diesel repair shop and allows us to look at many more system performance characteristics beyond average fuel output.

We test from idle to full power using factory calibration points and a few of our own points added for the high-performance market. We can fully map injector sets and have done so for a number of customers who want to best utilize their stand-alone ECU, or EFI Live capabilities.

We use equipment developed and used by Bosch for the design and development of diesel fuel systems (specifically common rail) and have the expertise on staff to properly operate and maintain this very sophisticated equipment. Some of our staff were part of the development of this equipment and common rail injectors when they were employed by Bosch. This equipment is not only able to measure injection quantity but also shot-to-shot consistency and injection timing.

Exergy Performance is a division of Exergy Engineering and is focused on the unique needs of high-performance diesel applications. The need for this specialized attention was recognized after assisting in root cause analysis of everything from rough idle to broken engine components caused by “well-meaning”, but “inexperienced and/or under-equipped” fuel system modifiers. Given our history in the world of diesel fuel injection, we have a distinct advantage in the areas of experience, innovation, and test equipment. Our story begins in 1944 when as part of General Motors our former department began producing mechanical unit injectors for Detroit Diesel Corp. As the years went by new products and many new customers were added as the department was “spun-off” as an independent company. This success was not taken lightly by the Robert Bosch Corporation who began buying shares in the early 90's, eventually becoming the full owner in 2000. During this time we participated in the design, development, and manufacture of the Bosch common rail systems currently used by the “Big 3”. Unfortunately, in March 2006, our group was eliminated in an effort to consolidate worldwide engineering resources. Exergy Engineering was born out of this closure as an independent R & D service provider specializing in diesel fuel systems. With our background in OE development and manufacturing, we bring a unique perspective to the high-performance world. We know what various features and specifications need to be to ensure proper function, how to produce them, and how to verify they are correct. The verification process/equipment we use is very untypical of a standard diesel repair shop and allows us to look at many more system performance characteristics beyond average fuel output. Our People have a Can Do Attitude, are Problem Solvers, Innovators, Winners are just a few of the many terms that have been used to describe our associates over the years. For decades, our associates have been providing specialized diesel engineering services to a broad list of OE industry leaders. Our people have been involved in every aspect of the product development cycle (design, test, durability, instrumentation, test equipment, and customer interface). This “know-how” is now available to the performance diesel market via Exergy Performance.
