@a-iz4pg I usually criticize video's pretty severely but you seem to be making unfounded comments? D4A has been overenthusiastic a few times ( which I have commented on) but pretty sure he's not a shill.

@jlo13800 Various two stroke 125cc motocross bikes were making over 36 bhp in the 80's, the road racing versions even more as they had narrower power band, 250 twins were making over 90bhp (Suzuki RGV 250 ROAD bike was 87 bhp in it's final iteration)

@ChevyConQueso I was wondering the same thing but didn't want to look like a 'fanboy' 😄

@prabowomantoro3945 Yeah, but Wankel was designed around 70 years ago and was totally innovative. This is basically a development from Wankel. I'm pretty sure it would not have been 'invented' without Wankel being produced first.

@mgk1397 major problem would be CARB as the California market is probably still the biggest single consumer? They already have mandates on lawn equipment, weed whackers and chainsaws

Norton did it with their Wankel engine in the 1980's, nothing new

This is a much better explanation than any other I've seen. I have often wondered how much pollution the military produces, various aircraft being extremely inefficient but VERY high output (eg, on afterburner) and no limits set by anyone. (instead, motorists have to 'suffer' increasing legislation to compensate) In a time of war or emergency, fair enough but general use 'on a jolly'? Anyway, a supercharger and turbo would allow much smaller ports allowing side seals to be moved into outer covers, ceramic coatings less heat loss. I still see issues with rotor expansion, one side of lobes being very hot and the other (relatively) very cold. Maybe multiple intake/exhaust ports to induce extra swirl plus even out massive temperature gradient? As diesels are direct injection, very high boost pressure can be used for scavenging, fuel being injected as usual during the burn cycle should allow a reasonably high rpm. I would think it won't be a problem to fit inboard oil seals to main bearings then use pressure fed mains at least, reducing cost and weight even at expense of adding oil pump and reservoir? Using 'specified' (two stroke) oil would allow a bleed off to lubricate internal gears. Service interval would consist of changing spark plugs and topping up oil.

@iddqd339 except fuel 'economy'

@petergriffin4629 do you have a link to the Achates engine? It's the first time I've heard of it but it may be a development of something from 1920's that I would recognise (I've studied engine design's, I'm not over 100 😁)Never mind, did a search. Basically a Junkers Jumo engine updated to 1990's technology. Nothing new

@rightwingsafetysquad9872 You missed the point, they used a hollow crankshaft because it actually worked but spent too much time and money they didn't have. If Norton's had not been so expensive trying to recover costs they would have sold more and possibly kept going. Margaret Thatcher did not want ANY motorcycles on the road in Britain so refused to help (unlike reagan in USA with Harley) Major problem was Norton relied on Police contracts with bikes that were terrible for low speed escort duty, they were fast though .

@rightwingsafetysquad9872 Actually, your original post didn't say anything except to point out Norton is not in business, no mention of a hollow crankshaft being used. Norton did it to cool rotor, LP look like they are doing it for same reason

@rightwingsafetysquad9872 As intake rarely gets above ~200c compared to exhaust at 400+c it is also used for rotor cooling, they just don't point it out. I make comments as a response to various ridiculous things people say and they are 'stand alone' majority of the time so people don't have to search through hundreds or thousands to maybe find a reference. When you assume you really are just an ass u / me
