Experience and Ingenuity
Engine Systems Innovation, Inc. founder, Steve Arnold has designed, engineered, and improved turbochargers for numerous OEMs. Millions of vehicles produced over the past two decades use and have benefited greatly from Steve’s advanced and efficient designs. Achieving maximum efficiency and lowest cost is our forte. We’ve worked with industry leaders and can’t wait to work with you.
Our Advanced, Patented Technologies
Continuously Variable Displacement (CVD) Engine. Our CVD will enable the highest fuel economy for engines powering automobiles, trucks and other low duty cycle applications.
PureFlow™ Compressor—a high flow range compressor with vastly higher efficiency and pressure ratio left of peak efficiency. Don’t let your compressor regurgitate and re-ingest its own entropy—it’s nasty stuff!
The VVT—ultra-high efficiency next-generation variable geometry turbine with no pesky vanes. Steve’s 5th Generation VGT is the best yet!
Take the next leap, not a step.
Work with us on your current challenge or brainstorm something new. From CFD or Rotordynamics, to design, manufacturing, or forensics and root cause determination, we live and breathe turbochargers.
Changing the automotive world is possible. We’ve done it before.

At ESI, our mission is to design better products—whether it’s your idea or ours. What sets us apart is our drive to find unique relationships in and between turbos and engines; then to find ways of changing the system to take advantage of these insights to achieve higher performance and lower emissions, including CO2. We strive to partner with forward-thinking clients to bring these insights to life, refining these ideas into reality for not only our clients and partners but the end-user owners, operators and drivers.
We are driven to share our knowledge with those seeking it. Our training focuses more on the “why” and “how”. Our world has changed and one can find equations and answers to questions with Google in a few seconds. But the “why” and “how” is what enables engineers to see beyond current thinking and imagine new functionality.
ESI founder Steve Arnold has been improving turbochargers for over three decades and is known for utilizing net shape technology combined with system engineering to bring world-class performance with low manufacturing cost to advanced turbochargers. This effort has produced 47 U.S. patents, 4 of which are assigned to ESI. Some of his awards include:
2014 First Place, NASA Tech Briefs/SAE “Create the Future” contest for Automotive/Transportation
2014 Received “Friendship Award” from Vice Premier Ma of China (the highest award given to the more than 600,000 foreign experts who have made outstanding contributions)
2011 Dual Boost Turbo received PACE award for Green Engine Technology
2011 Dual Boost Turbo received PACE award for Innovation
2008 SAE International “Excellence in Oral Presentation”
