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.
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.
