Seen this? Two-stroke engines on ecofuel? Geeee....what a future. We have vacuum cleaners today, landmowers tomorrow... https://www.motorsportmagazine.com/news/f1/two-stroke-engines-eco-fuel-f1-aims-be-greener-formula-e Rgds
I can't help but laugh, because I always think of the two stroke dirt bikes from the 60's and 70's: RING, ning, ning, ning, RING, ning, ning, ning, RIIIIING, ning, ning. Copious amounts of blue smoke as well. Good times.
It's all good news to me. I am glad that the combustion engine is fighting back. It's "crime" was to use fossile fuel, but that can be avoided with synthetic fuel. Remarkable that the 2-stroke, buried only a few years ago, could make a spectacular come-back and be a solution.
One of the developers of the original 2 stroke engine was trying to mimic the steam engine. The piston steam engine (locomotive) hits on both sides of the piston. No lost motion!
If F1 is trying to be more into advanced street car development, Do away with all down force and strictly mechanical grip?
Lost motion smotion.Tourquey they were....'not very efficient tho'. The four stroke diesel electrics have relegated them to museums, and historic fantasy tours...... The Wankel had it's advantages too. Few moving parts, powerful, and compact. 'Notice, have you, that they're both gone?
I have raised this argument for a long time. The rebuttal is "where would they hang their advertising?
The two stroke engine: trying to make a glorious come back since they stopped building the Trabant. I´ll believe it when I see it.
Of course you can mention the smoky Trabant if you want to ridicule 2-stroke, but you could also mention the last 500cc engines from Honda, Yamaha and Suzuki before MotoGP . They had buried the 4-stroke in term of thermic efficiency, power-to-weight ration and horsepower-per-liter. The 2-stroke engine has many advantages compared to the 4-stroke, less moving parts and less friction among them. Cheaper to manufacture too !!! 2-stroke is another technology that risks falling behind because it was abandonned for expedient marketing reasons at the time. Wait, the same also happened to ... electric power at the begining of last century. Look at it now !!! Even steam power could make a comeback for some applications ...
Come on, I´ve heard the same story every time someone tried to sell a new "revolutionary" two stroke engine. Less parts, blah, blah. Yet, nothing happened. I know how a two stroke engine works. I also know that they´re rude, noisy, less durable (yes, cheaper, simpler, but no lubrication --> they wear). And a small problem: more pollutant. And they´re already having trouble to get the 4-strokes within the pollution limits. The issue is a lot more complex than some "marketing reasons". Yes, I know that some still are working on the idea. Fuel injection, lubrication systems, counter rotating stuff to eliminate the vibrations... But I still haven´t seen those engines on the road.
The replacement of F1 is already here. In a journal on cinematography I came across the new series on Hypercar racing. It uses highly turned drifter cars of various configurations, racing each other through a high tech obstacle course complete with water traps, elevation changes, surface changes and required maneuvers...and of course the "obstacles." The track is filled with dramatic lighting effects that constantly change, camera rigged all over the course and in every car, all set in a "Bladerunner" looking set...the old Kodak factory and plant in Rochester, New York. The production is in the hands of action reality people who's credits include "BattleBots." The cars have more graphics than an MS 13 assassin has tattoos. If they'd only bring in the now unemployed grid girls and make it into "Naked and Afraid Racing, I'd be hooked.
You said you know how a 2-stroke works, yet you went on to say no lubrication. You don't know how they work.
Jeez, I suppose I have to be literal to get understood. Or are you just being finicky for the sake of it?
Riiiiiiiiiiiiiiiiiiiight. Last yr Ferrari knew exactly what tires they were getting, and were fully aware of what those tires represented based on the prior yr races where they were used. Ferrari still could not get it right (especially the MED) and it cost them several races. So here's hoping they maybe are beginning to learn.
Well, the definitive tyres for 2019 were only tried at the post-season testing, so it was not so easy to figure them out. I think they kept these tyres for 2020 just to remove a variable, even if they´re crap.
Some of the new variations on two strokes. Lubrication like a 4 stroke, forced induction in the ports no fuel injected till piston is near TDC and all ports are closed. Think like GMC two stroke diesel. Supercharger forced air in to ring of ports, Fuel injected at top, but no spark. Spark with gasoline.
I'm familiar with all the tech they have going into them these days. Certainly the last thing I'd want to hear is a 2-stroke V-6 buzzwailing away down the track. Just give us back V-10's and be done with it!
I don't think there would be any manufacturer interest in NA engines without hybrid power anymore. They have an eco image to maintain now.
