[Idea] Pivot Valves, Thoughts?

[Rolls]

What does everyone think of this? It has to allow less obstruction than a conventional valve, you would need some sort of strange seal for the valve stem as it would move sideways as well as up and down but I'm sure there is a solution for it.

What do people think, any good reason why this wouldn't work?

What on earth am I looking at...?

A cylinder with an intake port and a valve? I thought it was obvious.

edit: I labled the image, I left the exhaust port out for simplicity.

Too many moving parts to wear out and/or fail.

[Rolls]

Yeah this is more a thought experiment. Assuming there was zero issues with sealing and the hinges/weight etc, would a flap valve like that fill the bore more effectively?

[Kenna802]

another prob is that the gate looks like it has to move a long way when most valves open and close at a very small gap

[Dobz]

A more direct path for air/fuel to travel would fill the cylinder quicker but it would lack the turbulence required to evenly spread the mixture around the cylinder. This would cool down the side of the cylinder which is in the path of the intake flow causing one side to cool down more than the other which is no good for piston/bore clearances.

lots more negatives than positives. as said above wear, clearance and distribution would all be much worse off than a conventional setup. not to mention the impossible task of coming up with a method that doesnt put excessive sideways pressure on the valve and therefore seals.

[Rolls]

Here is another idea, rotary valve but I've fixed the problem of needing complex seals, thoughts?

the existing designs that require sealing that would be very difficult to do

oh lol, if only I drew it in 3D I would have seen the very obvious error in my design.

NO COMPRESSION, lololol

well your idea is used in the new turbonetics "newgen" external wastegates. seems to work well.

for an engine its no good. youve got hinges and shit + the way the valve works will not provide a evan mixture into the cylinder.

Talked about stuff like this when I was 18.

Decided that solenoids (ie direct injection) were a better way to go.

Once visteon finish their direct acting solenoid valves the world will be a better place - ie just punch in the valve opening and closing time and how much you want it to open. Then the petrol engines may catch up to the diesel in terms of torque and fuel economy with the help of HCCI and direct injection.

Yesssssssssssssssssssssss

Agreed, computer controlled solenoid operated poppet valves offers the best technology, but I have a feeling it's all a bit too late for the internal combustion engine.

Same goes for these guys>

The pivot valves also only have a 3 area's for flow around the valve due to the hinge.
