Rep Power: 584 its not a mystery that 2 stroke motors are monsters. they always have been. the only bad thing about them was that they dont use fuel efficiently and burn much more oil than a 4 stroke engine. they also produce more pollution. now, if this engine solves these problems, then you can bet that this is the next big thing.
i would LOOOOOVE to see some 2 stroke engines get put to use in something more than a chainsaw or a lawnmower. lol

Rep Power: 343 2 cylinders 4 pistons, intresting. too bad its extremely impractical because the outer connecting rod is limited on thickness they have to be made of exotic metals, titanium in this case
and actually the more i look at it the LESS efficient it appears to be. Because of its dual piston design it makes for very inefficient removal of exhaust gases.

Rep Power: 0 Normal 2-stroke engines (ie. lawnmowers, dirtbikes, snowblowers, etc) use an oil and gas mixture due to packaging constraints. The symplified design allows for a smaller and less complex engine, which is vital for these applications.
When you're talking about an engine this size, this is not such a factor, and it's possible that it has a lubrication system much like we're used to on our 4-cycle cars. If this is the case, then it would have better emissions than your average 2-cycle engine. Of course this is just speculation, and we'd have to see more specifications before we can be sure either way.
It will be interesting to see if some of these designs make it into production for mass-consumption applications, and also what the emissions are like on these engines.

how so? after all this engine is turbo'd. not to mention it's a 2-stroke engine. completely different than the 4-stroke engine in a car.

Rep Power: 0 Actually volkswagen was the first to use the horiz. opposed cyl(i belive less the considered steam years). And two stroke diesel have been around for along time. They are still used in trains in a diesel electric config., and in buses and so on. And all though there are no valves(some do have rotory valves) you can adjust the valve timing(which is called port timing) to tune the engine for specific apps. Like my jet ski can be ported for top end or alot of diff specs.

he's talking about the flat engine design in the Boxster. some people call the engine the "boxer" but just about everyone just calls them flat 4's or flat 6's. and its a little similar to the flat design in the Boxster and 911's, but has huge differences also. the biggest would be the porsche engine is a 4 stroke and "that thing" is a 2 stroke. the crank/connecting rod/piston setup is totally different too. I'd put it in my car though if it could turn more rpms. 2000rpm's is not enough for a car. there'd be a lot of blown motors around. and if you just made the gears super long, you'd have a lot of teeth breaking off the gears unless they were made of titanium. and no car company would make a tranny out of titanium....lol. just leave it in aircraft and such that don't require high rpms I say.

come on guys, don't argue over this. I don't think the original statement was clear enough. It could be interpreted in any number of ways.
i think we all know where the future of automobiles are headed...2 cylinders generating almost 600 ft-lbs of torque...with a thermal efficiency of 41%...holy ****ing wow...i wonder what kind of fuel efficiency that thing gets...

a guy named porsche designed it, his company named the boxster almost 50 years later...and just happened to put a boxer engine into it.
i'm thinking maybe you're the idiot.

Rep Power: 0 LOL I am surprised that this is even an issue. Go to how stuff works dot com. They have alot of cool diagrams and history on stuff you might not already know. The reason for the boxer is it looks like a boxer punching. But yes in the auto world flat is used more often. In this case in should have been used first thread. Boxer is an engine type and boxter is a car which is probly named after the motor(do not quote me). But to make it all square every one is right they are all similar engines. As for the use of that 2 stroke, I am sure it is extremely wide. And would not serve a purpose in a honda. I would belive that it would be used for generaters and super sized versions could be used to replace most other apps of diesel electric. I am just happy to see an efficient diesel. They have gotten a bad rep for alot of years but alot of what we do and need depends on them.

Rep Power: 267 and way to go, claiming a win in the flamewar from one person's post. the point still stands, the guy said boxster when he should have said boxer (or flat-six even, which he ALSO did not). noFriends was clarifying that point, like the troll he is. me, i just like to argue, hell, i sold my civic, i'm just here to stir up trouble now. go ahead, burn me bad, it might make me cry.
