james j neiweem Posted October 2, 2019 Share Posted October 2, 2019 (edited) Looks like the 2 cycle opposed piston diesel/gas engine is for real. Achates power is teaming up with Ford, Cummins, DOE and Fairbanks Morse. They have an F-150 with a 3 cylinder six piston diesel on display. It sounds a lot like a 2 cycle Detroit. Cummins is building an opposed piston in conjunction with Achates for the Bradley fighting vehicle and potential tank engine. Fairbanks Morse has teamed up with Achates to improve its 12 cylinder Marine and Stationary engine. (5000HP). Thermal efficiencies of almost 50% are expected due to less heat loss to the coolant. Sounds like exciting times. May bee KS can shed some light on this venture. Edited October 2, 2019 by james j neiweem 1 Quote Link to comment Share on other sites More sharing options...
glitchwrks Posted October 2, 2019 Share Posted October 2, 2019 Pretty cool! Some time last year I think I saw a video of their testbed F-150. Sounded a lot more like a wound up Detroit than the old Fairbanks-Morse powered tugs that we used to hear chugging up and down the Hudson (which were opposed piston two cycle).
