Traditionally 2 stroke engines generate 50% more power and use 50% more fuel than 4 stroke engines. If they eliminate the fuel usage problem inherent in 2 stroke carbs that give it such terrible emissions then it sounds good to me. Having a working prototype is probably Lotus' main point. But increasing compression from 10:1 to 40:1 is pretty handy. 10% improvement on Gasoline means if it ran on Alcohol or Diesel it could be even better. Mixed with turbocharging we're talking about cutting engine sizes in half and then by a third. Which means a theoretical 2.0l engine could be replaced by a TurboCharged 660CC motor!
And run on just about any fuel of your choosing.
Mixing oil with gasoline is obsolete already since they switched most 2 strokes here in the US over to wet sump years ago. Some of the comments, sheesh
.
But then I thought about it a little bit and realized it wouldn't be that hard to do. All you need is a bit of moveable real estate on the cylinder head side of the combustion chamber. Move it further into the chamber to increase compression ratio, and move it out of the combustion chamber to reduce it. It can't be a flat plate, it needs to have sides; make it round and you have a "puck".
