Engineered Power Systems (EPS) can now continue the certification efforts for its high performance diesel engine, Graflight V-8, which is designed to produce 320 to 420 horsepower. An undisclosed Chinese investor has committed to funding the New Richmond, Wisconsin-based company. EPS could not divulge how much money it will receive, but it claims the funding will be sufficient to complete the certification program.

EPS first announced its diesel engine program in 2013, hoping to become the first manufacturer to successfully certify a modern-day diesel engine for high performance airplanes. The company plans to seek Supplemental Type Certification for several platforms once the certification is complete.

“This is a clean sheet design that incorporates a long list of innovations intended to enhance engine efficiency and reliability,” said EPS’ CEO, Michael Fuchs. “Synthesizing all of the new technology with established procedures and materials created some significant challenges. Though they had an impact on our timeline and finances, we’re now beyond the obstacles and are comfortably on our way to the finish line.”

EPS now plans to start flight testing the conforming version of the engine. The proof of concept has gone through an initial round of flight tests on a Cirrus SR22 G2 airframe. However, the first airplanes slated for the Graflight 8 STC are the Airvan GA8 and Cessna 206. EPS also hopes to offer its engine to OEMs for new airplanes.
