I guess it will all depend on what type of engine they decide to go with.

I've seen something on boobtube where a guy converted an ac compressor into a motor. cant find it atm. but it was along this idea. had lexan heads on both sides so you could see the combustion/ explosion happening in all the cylinders. it used a single reed valve on each sides intake and only 1 side had a "carb". other side used the exhaust from the other side piped in to its intake. that was a 3/6 cylinder. I kinda want to build one. ive always liked rotary, aerial, and 2 strokes. this was all 3 packed into 1 engine. lets see what happens with these ideas. hopefully these designers don't end up in mysterious "accidents" before the big break throughs. I hope mr Edison isn't reading this... lol  |

found it. it was a 3 cylinder with the other side working as a reed intake/ supercharger thing. I think its really cool. I want to build one!!! www.youtube.com/watch?v=SxqyfB83tSo |

49GT I was thinking the same thing 4 cylinder Nahhhh! I only watch Formula E because i like racing and i think Formula E is good for driver development that's it .. Watching a Motorsport with no sound sucks no downshifts upshifts that stinks !
I hope F1 comes hard with the twostrokes it will change everything for twostrokes large and small . Michael Schumacher my alltime favorite in a V10 watch this then imagine it without sound ! LOL

I remember hearing such beauty at an opera featuring "Flight of the Valkyries". Glorious!!

Fuzzy, the research I have been lucky enough to see, is mostly based on existing fuels. The reason for such a broad range of fuels is partly the design of opposed cylinder, the shorter stroke, but moreover the ability to change compression simply. This part a bit of mystery, because there are many ways to do that. None complicated. All looking like 60% less moving parts.
The short-ish answer lays there...no need for exotic fuels. In fact, I saw one, first hand, while in a think tank forum, that ran on variable methane gasses, for use in super cold weather...to power and heat pipeline instruments! Took "off-gas" to burn the engine directly from pipe accumulators, to drive a tiny generator with battery assistance...solar. Ran solar in sunlight, ran off-gas when needed. Two drivers, one motor. Cool runnings!

What you are not seeing with F1, is that the "Two Stroke" technology they are developing is NOT as we know it...but better! Any of you heard of "Opposed Cylinder- Single piston"? I have studied the design and love it! Each cylinder had one piston that does it's job in opposite directions. A two stroke, that can burn any fuel, but does not require 2T oil. There are American developers, British, Italian, French... My interest is in engines for scooters and boats. I am working on tiny, surface drive outboards. These things are, on paper, super efficient and energy/emission compliant. I have seen a tiny 6 six cylinder, weighing under 350 pounds, (160 kg) that produce 300 + hp and over 620 lb ft of torque. Diesel big rig power potential, weighing nothing. I have further seen a proposed outboard, that can be scaled from 5 to 50 hp, and weighs 16+ kg... All in development. I to like the idea of aposed with no head and in tri configurations they made mad motors to go in the old pt boats in ww11 not 2t but I think u could make a 2t with no heads lol |

I'm going to put this out there since I do not have the funds to build and test. A four stroke cyl. and head. The cyl. has an exhaust port placed lower than a 2T and the exhaust valve has no rocker arm. (An Aussie member showed how he can greatly enlarge 2T ports by adding material to the outside of a cyl. leading to my thought of adding the ex. port.) The intake has a blower at 10 to 15 PSI. Cam speed equals crank speed, with intake opening about 20(?) degrees before exhaust port closes. Intake closes about 40 (?) degrees BTDC. (Possible reed valve between valve and carb?) Heat would require liquid cooling. Closed bottom end ends oil/fuel mix. Anyone had nightmares along this line you'd want to share?

Hydrogen + C from the air is great! What happens to the C after combustion? Methane! Oh wait  You get water out the tailpipe with this. My dad (who designed engines for CZ once) used to talk about this a possible future tech back in the early seventies. The problem is the huge fireball explosion if things go wrong at the pump. But I say that makes it twice the fun.  |

Michael Schumacher my alltime favorite Hope I edited that properly, it’s tougher on a phone. I really really miss the V-10 days in F1. I started to watch full seasons right after Senna died. Awesome years. I think I quit as Speedvision channel lost the rights and I didn’t have a source so I gave up watching it. Pedro Diniz was my underdog favorite but he didn’t ever do as well as I (or he) hoped he would. |
