Achates Power on Opposed Piston Two Stroke Engines 4-24-2013
Opposed-piston, two-stroke (OP2S) engines have a long and successful history that dates back to the late 1800s. Used in ground, marine and aviation applications, these engines are known for their record-setting combination of power density and fuel efficiency. However, despite two-stroke powertrain advancements, the engines suffered from high NOx and soot, along with poor oil control. Therefore, their use in on-road applications ceased with the advent of global emissions regulations. Yet with the technologies now available, there has never been a better time to modernize the OP2S.
The CALSTART Achates Power-hosted webinar featured John Koszewnik, Chief Technical Officer, Achates Power who provided an historical overview of opposed-piston engines and their inherent thermal efficiency benefits. Mr. Koszewnik also introduced attendees to measured results from an Achates Power OP2S engine which suggest that the technology can produce an economically and environmentally sustainable powertrain that can fit existing vehicles, be manufactured in today's engine plants, and run on a variety of fuels including diesel and natural gas.
