Inspired by the most famous engine in diesel aviation history, Achates Power is developing unique engine technology that offers an unparalleled combination of fuel efficiency and power density at lower cost. Well balanced at the cylinder level, the architecture is scalable and modular to address a variety of end-use applications. With over four years of dynamometer validation of its single cylinder, the company is now testing its 4.2L engine that rivals engines nearly twice its size.

With investment from clean technology visionary, the late John Walton, heir of the founder of Walmart, and significant design optimization by National Academy of Engineering Member, Dr. James U. Lemke, Achates Power was founded in 2004 to build the world's next generation engine architecture. Taking its name from the Greek mythological "faithful friend" Achates, the company's focus has been clear from the start: to build an engine that is light-weight, more fuel efficient, and lower cost. Inspired by Hugo Junkers' Jumo, the most famous engine in diesel aviation history, Achates Power has been developing and testing its unique architecture ever since.

With over 200 years of combined experience, the Achates Power Technical Advisory Board consists of 3 Members of the National Academy of Engineering and 4 Fellows of SAE and meets every 6-8 weeks to review the team's findings. On the TAB are Achates Power Founder and CTO, Dr. James U. Lemke, who holds over 80 US Patents for his inventions; Dr. John Beck, retired VP Research at Cummins; Professor David Foster, Chaired Professor at University of Wisconsin at Madison and Director of its Engine Research Center; Dr. Craig Marks, former VP Technology and Productivity at AlliedSignal and 27 years prior with GM; David Merrion, former Executive VP of Engineering at Detroit Diesel; and Professor Ward Winer, Chairman Emeritus of Georgia Tech's School of Mechanical Engineering.

Achates Power has raised over $50 million from Sequoia Capital, Rockport, and others.
