Just been looking at the Lotus Omnivore two stroke engine. The prototyoe is already 10% more fuel efficient than the most economical four stroke engine around. To see it working go to Google search. Lotus Omnivore engine. Click on (flash) Animation Lotus Omnivore Engine and see for yourselves. After you start it up you can alter rpm / engine load and petrol / alcohol mix and... well WOW its going to be big in say 10 yrs time.:sunny:

Certainly not a conventional 2 stroke and some similarities to a diesel 2 stroke. Doesn't say how it will be lubricated though so probably same as a conventional 4 stroke which means no nice exhaust or clouds of blue smoke on a cold start.

More power for a smaller engine size at a guess. Looks good though, I'd love to do micro-controller design for this sort of stuff :)

I would love another 2 stroke, it was the best at keeping tailgaters at bay.:D

Dont forget power from the engine is needed to drive camshafts in the four stroke. I was quite surprised just how much energy is needed to rotate a cam (on a single cyl engine) using just a spanner. All the technology is here now and nothing needs to be invented for this type of engine. Colin Chapman would have been proud of his Lotus engineers.

the old diesel two strokes used to be supercharged,they relied heavily on the blower maintaining a certain amount of pressure to enable a blow through type of charge though the crankcase but were filthy engines as the amount of lubricant that is also burnt made them uneconomical. They did produce huge amounts of power at quite high revs for a deisel.
I don't see any figures on how much oil it will burn as a result of the lubrication but with modern day bio oils and such like I imagine the emission figures will not be as harsh as a conventional two stroke. The whole reason they tried to oust the two stroke was not the amount of petrol it used just the emissions.

they did build it a couple of years ago (95ish)as a dakar bike but it never got of the ground, the faings and styling are more or less where they styled the 650/700 alp from.

Put a couple of tablespoons of castrol R in any petrol tank for that smell. i am sure the old boys from the Torbay kickstart club where doing that on the dartmnoor run last year, i think the Jawa 350 is being imported again,
anyhow i have 3 strokers on the road and 2 to rebuild at the moment
