Camless engine?

Mazda's made a camless engine for like 40 years...

I wonder why we have never seen a Wankel in a moto? Wankels are compact and light, which is perfect for motos.

Motos have very relaxed emissions requirements compared to cars, which I thought was the challenge with the modern Wankel in cars.
 
"infinitely variable valve lift and duration"
That is wet dream to a engine engineer, but hard to do both, without added complication.

Will be interesting if they can get the reliability solved before EV/battery tech beats the ICE.

I don't think this small evolution of the ICE will be enough to stop the EV revolution.
 
You would be surprised to know how small they can make a nuclear reactor and how long that it has been around.

You sure about that? Im pretty sure they cant touch the engine our transmission unless they fail or else its a grid penalty

Well, good question, I guess... you mean between qualifying and the final, that I'd believe.
End of the race day, I'm pretty sure those motors are gone thru, for safety reasons if nothing else.

Ill have to look into it because its my understanding the marshals have tags that are wired to different things so if the teams take something apart they know about it. Plus thier given a set number of engines each season..so if they could rebuild them, why would they need 8 engines?
 
Basically f1 teams get tokens that they can use to replace certain things...most major engine parts can not be changed tho..they get a total of 32, but a example is to change spark plugs it cost 3 tokens. So they add up very quickly. Search f1 tokens to learn more about them

those motors also get taken apart after every race, so long term reliability at the seals isn't really an issue.

Umm, There may be a race form/team, that does this...
But... Not all races are of that magnitude.

Just sayin, the variables are huge.

I don't think so either but I think the opposite is true:
If they can make tesla dized car with a battery pack that weighs 100 lbs and holds enough energy to drive 350 miles at freeway and mountain speeds and can recharge in 10 min...

ICE in any form would be pretty obsolete and have very little market demand.

Thus killing the tech in the OP

Well "Clean Diesel" did not really pan out. Ecoboost -F150 is having issues.

The Tesla Model S is not that far off:
270 miles EPA range
30 min FREE 80% charge at a Supercharger station (3400 superchargers world wide)
2.8 second 0-60 MPH (EV acceleration does not give a shit about a heavy battery pack)

Tesla did demonstrate battery swap FASTER than fueling up a ICE and then inviting Tesla owners to participate. After only 5 owners showed interest and only swapped the pack one time, Tesla concluded that the Supercharger Network was much better. Think about it. After driving, 2.5 to 3 hours, a 30 min break is not a crazy drive to rest ratio. We are really talking about a corner case. Once there are a million Teslas on the road there probably will be enough interest to make it worth while.

B&W have been using them on ships for a number of years. Two stroke slow speeds. Hydraulics actuate the exhaust valves and fuel pumps/injectors. ME-E engines.
