wrack Posted December 13, 2013 Share Posted December 13, 2013 Is anyone here following the OPOC engine development? I was following it until 2011 and then got busy in few things and haven't had a chance to do so. http://www.ecomotors.com Link to comment Share on other sites More sharing options...
+Mirumir Subscriber¹ Posted December 13, 2013 Subscriber¹ Share Posted December 13, 2013 OPOC engines have a whole history of development. They've been thoroughly researched, all their pros and cons are known. Link to comment Share on other sites More sharing options...
manolis Posted December 16, 2013 Share Posted December 16, 2013 A look at the PatOP engine at http://www.pattakon.com/pattakonPatOP.htm may be interesting or a look at the OPRE engine at http://www.pattakon.com/pattakonOPRE.htm or a look at the PatMar engine at http://www.pattakon.com/pattakonPatMar.htm or a look at the PatPortLess engine at http://www.pattakon.com/pattakonPatPortLess.htm Compare EcoMotors' OPOC to anyone of these engines.

wrack Posted December 19, 2013 Author Share Posted December 19, 2013 Thank you. I didn't know these existed but are any one of them close to reality production as the eco motors one? Link to comment Share on other sites More sharing options...
manolis Posted December 20, 2013 Share Posted December 20, 2013 Hello Wrack. EcoMotors' OPOC is not closer to "reality production" than the mentioned pattakon engines. There are several difficult technical issues (problems) EcoMotors has yet to address (to solve) before production. For instance, think about OPOC's lubrication. The OPOC is a conventional two-stroke engine (actually, it is a pair of Junkers-Doxford sharing the same crankshaft for the sake of the vibration-free operation). Take the near to the crankshaft exhaust piston of the OPOC. Its skirt opens and closes the exhaust ports; it also thrust heavily onto the hot cylinder wall above the exhaust ports (there is where the torque is generated); plenty of oil is necessary around the exhaust ports (to avoid scuffing) increasing the specific lube consumption (gr / kWh) and the emissions. Take also the EcoMotors variable capacity (deactivation of OPOC modules) and compare it to the variable capacity mentioned at http://www.pattakon.com/pattakonPatPOC.htm On the other hand think how close - technically speaking - to production is the PatMar engine of pattakon. With the proper equipment PatMar could get into production in a few weeks. EcoMotors has several famous investors (like Bill Gates); all doors are wide open. For several years EcoMotors has the necessary funds to start producing OPOC engines (did you see one?). EcoMotors has not a good product to produce and they know it. The OPOC engine is not yet good enough to compete the existing Diesel Engines. If I were a big investor of EcoMotors I would seriously consider asking for a license to built PatPortLess engines instead of OPOC engines (they are so similar ? take alone the distant piston of the OPOC - and at the same time they are so different).
