Score!

"During the intake stroke, the piston moves downward, drawing a fresh charge of vaporized fuel/air mixture. The illustrated engine features a poppet intake valve which is drawn open by the vacuum produced by the intake stroke. Some early engines worked this way; however, most modern engines incorporate an extra cam/lifter arrangement as seen on the exhaust valve. The exhaust valve is held shut by a spring (not illustrated here)."

In an overhead valve engines didn't come along until the early 20th century, because everyone in the 19th century was using side valve engines sort of way.

Are you really that nit picky that you're gonna go on about where the intake valve happens to be situated in the diagram? You realize that some motor have sideways firing pistons right? Then what? Oh don't tell me you were the lead engine designer for Volvo in the 1970s....

Springless intake valves but the exhaust had springs though? How in the hell would that work? The air would take the path of least resistance and blow back out the intake valves.

Hmmm... well not if the valve is one way, so to speak... although I must confess to wonderin what keeps it seated until vacuum opens it? The pressure of the exhaust gasses until they are released?

But see it would work more like a 2 stroke at that point. Intake, exhaust, intake exhaust. Where is your compression and power stroke (both valves closed)? Seems like the power stroke would open the intake valve and blow the exhaust out.

The power stroke is caused by the explosion in the cylinder.

The fuel is expanding pushing out in all directions. The same force that drives the piston down would be forcing both valves closed.

The only time there is a lack of pressure in the cylinder is during the intake stroke.

"Intake over Engine" configurations (what Phenix is referring to) aren't the same as OHV configurations, as shown in the original diagram. I don't give a fuck if the maker of the website is Albert Einstein, no one ever made an OHV engine with spring-less intake valves. (Except Ducati...)

Here's a picture of an IOE engine:

http://blog.autoworld.com.my/wp-content/uploads/2009/01/f-head.JPG

Does the intake valve move up and down all by itself? No, dumb ass, it does not. :lol: Harley's very first engines used a vacuum operated intake valve, but not in an OHV head.

BTW, the direction of the piston, up and down, back and forth, sideways, or at an angle up your ass, has no bearing on the function of the valve train, so why don't you go polish something shiny, and shut the fuck up.

Yeah but wouldn't the downward motion of the piston pull the intake valve open? I guess what your saying makes sense, i just have a hard time envisioning it. But what else is new? With no spring to keep the valve closed why would it not just stay open at least part of the cycle. It certainly would not have been as efficient as today's engines with springs on both intake and exhaust. .

We have a bingo.

The design worked so well, that Harley used it for maybe 2 years (?) before they switched to a cam driven intake, similar to the later flathead motor.

The direction of this piston doesn't matter.

You are thinking down = pulling.

The "pulling" effect is the low pressure environment on the intake stroke. On the other three strokes, cylinder pressure is greater than its surroundings which would force the valves closed.

I understand having trouble visualizing it. If only someone would design a website with an animated example...

It was used in cars before it was used in bikes.

Tmall
07-16-2009, 08:28 PM
A 6 stroke uses water injection instead of fuel for 2 strokes.


The water flashes off, expands and acts on the piston like combustion would.

I've only heard of it in diesel engines and it significantly lowers operating temperatures. You save a lot of weight by a smaller cooling system, but you have to carry around a tank of water.

I'm also unsure if the water needs to be treated or not, or if you can fill it from a garden hose.

There is also one with 2 pistons that face each other and the top piston uncovers the valve type area the top pston turns at half the speed of the bottom one so you get 6 strokes for the normal four.

The other one is a gas or diesel engine that also has a steam stroke by directly injecting water in to cool the engine and make a extra power stroke.
