SoonerLS Posted January 31, 2018 Share Posted January 31, 2018 From NAIAS, the Achates opposed-piston engine: And before Pioneer strokes out, look what Achates is using for their testbed. 2 Quote Link to comment Share on other sites More sharing options...
mackinaw Posted January 31, 2018 Share Posted January 31, 2018 On a recent Autoline Daily, it was reported that a major North America OEM is interested in this engine. Quote Link to comment Share on other sites More sharing options...
akirby Posted January 31, 2018 Share Posted January 31, 2018 That technology is really impressive. Will be interesting to see how it performs in the real world and any drawbacks or compromises. Quote Link to comment Share on other sites More sharing options...
92merc Posted January 31, 2018 Share Posted January 31, 2018 TFL Truck did a video on it a bit back. 2 Quote Link to comment Share on other sites More sharing options...
jpd80 Posted January 31, 2018 Share Posted January 31, 2018 Impressive technology, I hope they cure the oil consumption issue and get it to market as it might be just the ticket to extend ICE for another 10-15 years. One of the benefits of so much research into delivering electrification is that it also forces manufacturers to look at other alternatives for gas and diesel engines. Nothing like a bit of competition to make engineers reach for goals once thought impossible. 1 Quote Link to comment Share on other sites More sharing options...
silvrsvt Posted January 31, 2018 Share Posted January 31, 2018 Opposed Piston engines have been around for 100 years. Real world implementation of them has been a headache. 1 Quote Link to comment Share on other sites More sharing options...
Mad Hatter Posted February 1, 2018 Share Posted February 1, 2018 Opposed Piston engines have been around for 100 years. Real world implementation of them has been a headache. I remember an Australian..maybe Austrian company was gearing up to produce a scotch-yoke engine maybe 20 years ago (didn't Navistar have a prototype a few years ago, too?). Clearly, something didn't work out. Quote Link to comment Share on other sites More sharing options...

Clearly, something didn't work out. Junkers had an aircraft engine they where working on in WW2 The Russians, now Ukrainians had this type of engine in the T-64 MBT-they had major headaches with it, but newer version isn't as bad...but not as good as a "standard diesel" Quote Link to comment Share on other sites More sharing options...
twintornados Posted February 1, 2018 Share Posted February 1, 2018 The biggest issue I see is the gears on the back of the engine to combine the rotational power and send it on its way... Quote Link to comment Share on other sites More sharing options...
lfeg Posted February 1, 2018 Share Posted February 1, 2018 Low speed opposed piston engines have been used for years in the power generation and backup power world. Efficiency and longevity were just two of the reasons. This is just using the opposed piston principle in a different application with current materials and technology. I say go for it! 1 Quote Link to comment Share on other sites More sharing options...
akirby Posted February 1, 2018 Share Posted February 1, 2018 The biggest issue I see is the gears on the back of the engine to combine the rotational power and send it on its way... That’s exactly how dual clutch transmissions work - no issues there. 1 Quote Link to comment Share on other sites More sharing options...
jpd80 Posted February 1, 2018 Share Posted February 1, 2018 What was said in the video was that due to there being no cylinder head the pistons are so hot that it causes issues with oil consumption, I think that's something a major OEM like Ford or GM could cure. 1 Quote Link to comment Share on other sites More sharing options...
