Q&A

Achates Power's 2-stroke, opposed-piston, compression-ignition, multi-fuel engine marches toward multiple applications - and series production in 2024. Larry Fromm explains.

Global demand for cleaner, more power-dense internal combustion engines (ICE) is expected to continue into the middle of this century, for a variety of vehicle applications and markets. San Diego-based Achates Power has been developing its solution - an advanced 2-stroke, opposed-piston, multi-fuel, compression-ignition engine - since 2004, the year computer engineer Larry Fromm joined the start-up to lead business development. Automotive Engineering recently caught up with him to learn about Achates' progress in moving its innovative OP power unit toward series production in 2024. Highlights of our interview are below.
