The History of The Achates Engine

Meet Dr. James Lemke – a serial entrepreneur with a passion for science, engineering and education and a track record of using scientific and engineering breakthroughs to create new products and companies.

Dr. Lemke founded Achates Power in 2004 with an idea that will revolutionize the automotive industry. His stroke of genius was recognition that advances in computer aided engineering and engine component technology enable the revitalization of the efficient opposed-piston engine.

Lemke realized that more efficient transportation solutions are required if we are to maximize the utility of the world’s finite petroleum supply, particularly in light of carbon dioxide and climate change concerns. Dr. Lemke started Achates Power with a group of engineers and scientists, and a focus on scientific and engineering fundamentals. As each technical challenge was overcome, skeptics turned into advocates. Current measurements show a 30% fuel efficiency improvement compared to the industry’s best diesel engines and nearly double the fuel efficiency of a standard gasoline engine with everything else (power, torque, emissions, noise, cost…) held the same.

Here is the story of how “light reading” on a Mexican vacation turned into the concept and development of one of the most revolutionary engines of today – The Achates Power Engine.
