N1GTR Posted January 13, 2012 Share Posted January 13, 2012 Wow, wait till aftermarket ECU tuners get their hands on that and can play with variable compression from 7.0:1 to 18.0:1. On top of varying fuel and boost already. I wonder why they're using the whole separate rod and piston driven off the crank to control the compression instead of an electric device with a rod and piston driven off that. Maybe it makes too much mess around/external to the head Link to comment https://www.sau.com.au/forums/topic/388121-interesting-new-engine-technology/#findComment-6187199 Share on other sites More sharing options...
Hipcrostino Posted January 13, 2012 Share Posted January 13, 2012 They indicated it was a 100% mechanical setup so thats probably why. I wonder what they use to move the actuator that adjusts compression. That is one awesome technology. Now if they can make it strong enough to handle some real power!

StevenCJR31 Posted January 14, 2012 Share Posted January 14, 2012 didnt play the you tube vid as this computer seems to get viruses from you tube all the time ,VCR is old technology . . was reading about an old test engine used in TAFE,. . . .they could raise the compression of the engine by lifting the head closer/further away from the pistons, not sure how they did it but it was within the grasp of first year students Link to comment https://www.sau.com.au/forums/topic/388121-interesting-new-engine-technology/#findComment-6188301 Share on other sites More sharing options...
GTR_JOEY Posted January 14, 2012 Share Posted January 14, 2012 Except in this instance they arent moving the head, instead they are moving the position of the rod and piston (up and down) in relation to the head Link to comment https://www.sau.com.au/forums/topic/388121-interesting-new-engine-technology/#findComment-6188312 Share on other sites More sharing options...
StevenCJR31 Posted January 14, 2012 Share Posted January 14, 2012 this is true ^^, if this engine design makes it into regular production cars it will be interesting to see how durable it is compared to the current crop of engines, good to see some new devolopement coming out as there doesnt seem to be a lot going on with manufacturers (apart from hybrid tech) lately Link to comment https://www.sau.com.au/forums/topic/388121-interesting-new-engine-technology/#findComment-6188340 Share on other sites More sharing options...
Chris Rogers Posted January 15, 2012 Share Posted January 15, 2012 that is neat. the end of it though makes things more interesting as they mention VVT and forced induction. overall someone had a bright idea to make an engine more efficient. that certainly does that. also like the comparison vs hybrid.

Kinks Posted January 22, 2012 Share Posted January 22, 2012 Not really a new concept, Saab did this in 2000 and unveiled a motor that had a tilting head which varies the CR. Haven't heard anything since then. The geared conrod method is different, Saab probably patented the tilting head. Wonder how the intrinsic strength of both solutions stacks up...

Wonder how the intrinsic strength of both solutions stacks up... it would be good if it was out soon on cars, you would be able to have the ecu read the octane of the fuel in the tank and adjust the CR too suit , , ,run anything from cats piss ULP to E85 (and anything in between)without having to lift a finger Link to comment https://www.sau.com.au/forums/topic/388121-interesting-new-engine-technology/#findComment-6199258 Share on other sites More sharing options...
Tbs260Z Posted February 8, 2012 Share Posted February 8, 2012 Nissan's version is better if you look at that tiny gear wheel below the piston that has to take alot of force you can tell that's a potential weak point. Plus nissan's version suits a reciprocating motion better. http://www.nissan-global.com/EN/TECHNOLOGY/OVERVIEW/vcr.html Link to comment https://www.sau.com.au/forums/topic/388121-interesting-new-engine-technology/#findComment-6224711 Share on other sites More sharing options...
Beelzebub89 Posted February 12, 2012 Share Posted February 12, 2012 Yeah the engines only been in development for 15 odd years.

FloydWestwood Posted February 15, 2012 Share Posted February 15, 2012 Yeah it's old technology - another way to do it is to set up the head with high comp ratio and use psid controlled valves to dump pre combustion fuel/air mixture into exhaust. It's wasteful and not good for the environment, plus adds too much plumbing around the engine.

4PIMPN Posted April 2, 2012 Share Posted April 2, 2012 re-vamped old technology, but good idea for passenger cars, but will never make it in the performance side of things Link to comment https://www.sau.com.au/forums/topic/388121-interesting-new-engine-technology/#findComment-6299918 Share on other sites More sharing options...
