dan106 Posted February 27, 2013 Share Posted February 27, 2013 Just got this sent to me by a mate, definately worth 10 minutes watching if your interested in engines and all that Quote Link to post Share on other sites
shorty Posted February 27, 2013 Share Posted February 27, 2013 like wankle engines then? Quote Link to post Share on other sites
dan106 Posted February 27, 2013 Author Share Posted February 27, 2013 Good point, didnt think of that haha, but seriously if you havent watched it, do watch it, opening and closing valves with actuators instead of cams, koenigsegg's design! Quote Link to post Share on other sites
morgey Posted February 27, 2013 Share Posted February 27, 2013 I saw this a few weeks ago, think the likes of f1 ha been using something like this for a while to get the revs that they do but, 30% more effecient, power and torque with less weight.Can make as much power and torque in a 3cylinder 1.5 as a camshaft driven 4cyliner 2.0And no its nothing like a rotary as they use ports not valves ;) Quote Link to post Share on other sites
daniel_g Posted February 27, 2013 Share Posted February 27, 2013 The new ford 3 cyl 1L ecoboost engine has no cams. The valves open electronicaly. Pretty efficient design, makes 125 bhp. Quote Link to post Share on other sites
shorty Posted February 27, 2013 Share Posted February 27, 2013 lol im aware of the concept i just ment there has been camless engines for donkies years im an F1 whoare!!! and engines make my balls twitch, i love engineering tech. Quote Link to post Share on other sites
Amjad Posted February 27, 2013 Share Posted February 27, 2013 Are those new Ford engines reliable? Quote Link to post Share on other sites
morgey Posted February 27, 2013 Share Posted February 27, 2013 The new ford 3 cyl 1L ecoboost engine has no cams. The valves open electronicaly. Pretty efficient design, makes 125 bhp.They still have cams, probably contolled like the fiat multiair system, just had a quick read and they have a timing chain. But yeah size of an A4 peice of paper! Pretty impressive little engines it would appear Quote Link to post Share on other sites
daniel_g Posted February 27, 2013 Share Posted February 27, 2013 Yeah... they do, heads fried this week haha, balls. My college lecturer was talking about some new engine that has no cams, and one where the cams werent drivin by the crank, instead by an electric motor... Then he was banging on about the ecoboosts and how good they were.. Quote Link to post Share on other sites
daniel_g Posted February 27, 2013 Share Posted February 27, 2013 Just checked my notes, the 3 cyl 1L ecoboost is drivin by a belt that runs through oil... Quote Link to post Share on other sites
morgey Posted February 27, 2013 Share Posted February 27, 2013 Haha im feeling the same dude! I dont like the sound of electric driven cams, well i would never use it in an interference engine anyway!! Crazy this modern technology hey! Quote Link to post Share on other sites
daniel_g Posted February 27, 2013 Share Posted February 27, 2013 Yeah, especially in cars, i'll stick to my wee basic starlet thanks very much haha.Got to think though, if the modern auto technology was pumped into a starlet it would be a totally different machine.But i do prefer the kinda old school feel to them, no interference from a computer haha.

morgey Posted February 27, 2013 Share Posted February 27, 2013 Yeah cant beat good old mechanical cars, might not be as efficient or what ever but simple for people like us to work on and a much more connected feel imo! Quote Link to post Share on other sites
Chris Green Posted February 27, 2013 Share Posted February 27, 2013 That's real interesting, hypothetically speaking in say 10 - 15 years time if these go mainstream, surely large tuning companies will be offering these as an upgrade rather than high lift cams?

Thats what i was thinking of when i was watching that video, What about Vtec? 20,000 rpm haha Seems really great and he said they havnt had any trouble with it eathier Quote Link to post Share on other sites
morgey Posted February 27, 2013 Share Posted February 27, 2013 (edited) I suppose i they wanted to, theres nothing stopping them now? These guys have done it to a normal road car so whats stopping you from removing the head from the likes of an evo and making a retro fit camless head. The only thing you would need is oil pump drive if its belt driven and a crank angle sensor for timing and ignition etc The valves would need a separate cpu but nothing mentalAnd how would you get vtec with no cams? LolOr are you saying? "vtec pffft, i rev to 20k bitch!!!" :Pb Edited February 27, 2013 by morgey Quote Link to post Share on other sites
dan106 Posted February 27, 2013 Author Share Posted February 27, 2013 This is also worth a watch for those who havent seen it All i can think of is, if they can build that engine that well, imagine what they could do if it was camless? Quote Link to post Share on other sites

Yeah vtec this lol Quote Link to post Share on other sites
RandomDan Posted March 8, 2013 Share Posted March 8, 2013 (edited) Havnt they had numatic valves in racing bikes for a few years now? Just watched the whole thing now and it looks great.If the numbers are as good as they state it could be something amazing! Edited March 8, 2013 by RandomDan Quote Link to post Share on other sites
H_D Posted March 8, 2013 Share Posted March 8, 2013 Thats what i was thinking of when i was watching that video, What about Vtec? 20,000 rpm haha Seems really great and he said they havnt had any trouble with it eathier Honda no longer make Vtec engines due to emmission regulations Quote Link to post Share on other sites
