Exergy Performance

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.
