YES! Enough of the V6 turbo and electric stuff in racing. I wanna hear some 2Ts wound out!

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 have seen a lot of discussion about the single piston, twin cylinder. Very mixed opinion on what it will actually do.
Can't wait to see how this play out though.

The article eludes to using hydrogen as the fuel - "made by combining hydrogen with carbon captured from the air." In other words, it is not the typical (2)H2 + O2 ==> (2)H2O chemical reaction. So, what is it?

Wait- single piston, twin cylinder? So, were still talking about valves here?
Not a real 2t imo. Just some double-4t abomination.
Let's just use old-school 2t tech with alcohol and vegetable oil as premix fuel. Thats green, right?

Hydrogen + C from the air is great! What happens to the C after combustion?

YES! Enough of the V6 turbo and electric stuff in racing. I wanna hear some 2Ts wound out! They haven't used V6s in years they run inline 4s. The 6 went out the door when they went hybrid. Still way better then Formula E. |

Let's just use old-school 2t tech with alcohol and vegetable oil as premix fuel. Thats green, right? Hahaha! Actually benji, I have seen variations of this engine that cover intakes with reeds, rotary valve and OHV. Yes, all TRUE two strokes. Fire every other cycle on each side. More like a twin 2T, but with one piston serving opposing bores. A two stroke on steroids. OH...can burn near any fuel, based on ignition and fuel mapping. Obviously, more power in heavier fuels, but hydrogen? Likely, but hard to make power unless compressed. The UK connection I am trying to bore into...is building an adjustable stroke variation, thus can adjust the HP and torque range. YES, true two strokes...look up the history and you will find that the idea is not new. The lack of need for 2T oil is due to the length of stroke being uber short, therefore less heat generated, even at decent compressions. More important...tiny. Light weight. Fun potential. For a scooter? WOW! The one big feature that would appeal to some and turn others away is the fact that this design is quiet. Generates less noise. Much less noise. |

Still way better then Formula E. Is there another Formula 1 that I'm unaware of? Since they gave up on the screaming monsters, they've been using 1.6L V6 engines, unfortunately limited to 15,000RPM. Regarding the rest of my comment about turbo V6s in racing; IRL uses a turbo V6 and even NASCAR is even now thinking about giving up on the naturally aspirated V8s for a turbo V6. Sadly, look at the manufacturer support in Formula E. Electric seems to be what the manufacturers actually care about. |

I googled with no satisfaction yesterday. The F1 article says "improved sound," the MotoGP article says "great sound from the exhaust" while ThaiGyro says "this design is quiet." Are we talking about the same thing? I'd also really like to know what the fuel is, that seems to be the key. Probably $100/gallon. |
