Back to the top Achates Power Fundamentally Better Engines Clean, Efficient Diesel Engines When we started Achates Power in 2004, we hoped to take advantage of the inherent efficiency of the Opposed Piston engine while matching the emissions compliance of conventional engines. Interestingly, we found that not only do the OP Engines offer substantial efficiency improvements, they have important advantages in reducing NOx – so much so that the California Air Resources Board is funding a Class 8 Heavy Duty Diesel Demonstration Program to demonstrate the ability to reduce NOx by 90% while also reducing CO2. Robust Compliance Diesel after-treatment systems are essential to nearly eliminate harmful emissions like NOx and particulate matter from the engine but degrade when subject to high temperatures. The OP engine substantially reduces extreme thermal excursions because it offers more robust compliance and longer after-treatment system effectiveness. The proprietary cylinder and piston designs achieve important improvements in thermal efficiency while minimizing emissions. Based on its unique technology, Achates Power is creating clean, more fuel-efficient and lower-cost engines for the 21st Century. Mitigating Emissions with Higher Standards Commercial vehicles are 5% of total vehicles on the road, yet use 25% of the fuel and emit 40% of the oxides of nitrogen. The Opposed-Piston Engine has the potential to improve heavy duty (HD) class 8 truck fuel efficiency with a 90% reduction in NOx and a reduction in CO2 to EPA’s 2027 levels. Reducing tailpipe emissions and CO2 emissions at the same time is essential to meeting our transportation goals. 4060 Sorrento Valley Blvd. San Diego, CA 92121 +1 858.535.9920 Quick Navigate Home About Achates Purchasing Terms Privacy Policy News & Blog Resources Careers Contact Subscribe to the Achates Power Newsletter © 2020 Achates Power, Inc.

Back to the top Achates Power Fundamentally Better Engines Examining the Low Emission 10.6-Liter, Opposed-Piston Engine From Achates Power September 27, 2021, by Vlad Radu Designed in the U.S and tested in a Walmart delivery vehicle all summer long, this revolutionary opposed piston 3-cylinder seems set to prolong the life of ICEs. However, you won’t be seeing it inside a mass-produced passenger car, as it’s meant to power 18-wheelers. In the era of mass electrification, we rarely hear about a completely new, large displacement engine being built. Even manufacturers of heavy-duty trucks are moving towards hybrid, battery-electric, or even hydrogen power. Nevertheless, one U.S. company decided against abandoning the ICE and instead chose to redesign it. Click here to continue reading.
