- Q: Need some info. Ok, four valves per cylinder is better than two valves per cylinder. Fine, why did Ford REVERT to only 3 valves (my guess is to save cost SOHC)? Audi and VW are using five valves per cylinder on some cars, does this offer any advantage over a four valve engine? Maserati even experimented with a six valve per cylinder!!!! (see link) http://www.maserati-alfieri .uk/alfieri26.htm but abandoned it (my guess is cost again?) Why are we stuck at four valves or would more valves actually render more horsepower? Pop some ideas best answer to reasonable answer...
- One advantage is that of pressure differentials. For the intake of a non-aspirated engine, not supercharger, the pressure differential between the atmosphere and the cylinder is about 14.6 lbs. maximum, atmospheric pressure. For the exhaust there is a high pressure in the cylinder and therefore it is easier to clear out most of the burned fuel mixture. So exhausting the cylinder is easier than getting the fuel-air mixture into the cylinder. It is a bit simpler to make one large exhaust valve and two smaller intake valves as far as the layout of the valves in the cylinder head. You save on parts is one consideration. Also, high revving engines make more horsepower but passenger cars never see the advantage of higher horsepower like racing engines do. If you build racing engines, it is not that difficult to use the same cylinder heads or last years heads. If you don't build racing engines, you are not worried about high horsepower designs and more about keeping the cost of the engine reasonable. You probably never use all the horsepower your engine is capable of delivering so why pay for more engine than you will ever use?
- Q: i have a 05 kx250f, new valves recently,will pop start, idle runs high, has compresion, new kckstarter gear but it wont kickstart. someone said the valves need to be shimmed.anybody have any ideals? thanks.

- Q: Specify eight technical requirements that you would consider important, when deciding upon a particular control valve?
- 1] I assume that by control valve you mean a variable orifice valve, not an on/off valve. 2] An answerer to your other question listed Metallurgy, temperature, pressure and shutoff requirement To which I note that if you need a tight shutoff you should not trust a control valve to do that, but should add an on/off valve in series. Also, metallurgy covers corrosion requirements but not obviously so 3] To which I add: flow rate [or Cv] and pressure drop fail open or fail closed response time signal input [3-15 psi, 4-20 mA, 1-5V, etc] connections [ie, fitting type] packed vs sealed might need to look at hard seat materials and/or replaceable seats, to control erosion reliability, ease of maintenance, availability of spares, timing on that vendor permanence [ie, are they entering bankruptcy ?] Cost
- Q: im just bored so heres my question who do you think is better valve games (hl2 tf2 css) or bungie games (halo) and why. whoever gives me the best reson gets best answer. personally i like valve
- As far as I'm concerned, it is valve for its dedication to their havok graphics engine for the pc. While bungie has a great track record for the Halo series, it is in no way comparable to what is involved when creating a graphics engine. Just an example of how great it is, tons and tons of people still play Counter-Strike: Source (Halflife2 Multiplayer) even if it is not a next gen game anymore. And on top of that, there were no games available that could be compared to the first Halflife. It was a breakthrough in gaming to combine adventure elements with shooter gameplay. That's my reasons and I'm stickin' to it.
- Q: have a 86 flhtc had new cylinders 10-1 pistons supposed to be 86 cubic inches when i run it up to 90-95 bending valves what can i do to stop bending valves-------HARLEY DAVIDSON
- The other answers are on the right track, but are failing to include the other possibilities. You say you have had the heads done...WHO did the headwork? Were oversized valves installed? What valve springs are you running and were they packed for proper and even seat pressures for the cam lift? Were the valve seats cuts for new valves and if so, was proper valve stem height set? What cam are you running?...What is the TDC lift on that cam? Were ALL clearances checked when the engine was assembled?...Meaning valve-to-valve clearance during valve overlap, not enough clearance and the valves will hit each other...valve-to-piston clearance, this is where the cam's TDC lift specs come into play, if you don't have the proper clearance, the valves will hit the piston........MINIMUM of .060 clearance on both of these checks. What lifters and pushrods are you running?...stock lifters can pump-up at high rpm and lift the valve too much causing it to contact the piston or the other valve. Are you 100% postive you are adjusting the pushrods to their manufacturer's specs...different pushrods manufacturers use different thread pitches that require different adjustment lengths. As you can see, if the engine wasn't PROPERLY built and all clearances checked, you have a MAJOR job ahead of you, this require extensive knowledge and tooling. If you assembled the engine, take it to a reputable performance shop and let them check it out, if a shop did the work, FIND ANOTHER ONE!!! Building performance engines is not easy work and not for the novice.
- Q: I started out playing trombone in middle school, then switched to euphonium as my main instrument. (I still play trombone for marching and jazz band, but I'm a little better at euphonium.) That being said, should I get rotary valve trombone or the one with axial flow? I only have a student trombone right now... And I have a professional Besson euphonium.
- We had one that was hard to dial. Thought I broke the tip of my finger off! That was the day of the 5 digit phone number.
- Q: What kind of valve is on this tennis ball cannon in this picture?
- It's a pneumatic valve with a compressed air tank to power the cannon. Any kind of pneumatic valve should do the trick, just make sure you use the correct fittings for whatever valve you buy. The red lever piece is from a standard pressurized air system for a mechanic's shop. It is probably only necessary as a safety mechanism to discharge the air without shooting the ball.
- Q: Hi, I'd like to control a three way solenoid valve like this one:understanding is that an electric current through the solenoid will cause the valve to let air one way while no electric current will have the air flow the other. Is there a piece of equipment like a control box (that can communicate w/ a computer) that would allow me to control the solenoid valve like this? and if so, where would i be able to find something like this....i've googled but no success. I eventually want to control the valve from a computer. Thanks

- Q: I see a valve that says FNW on it with ( on, off ) but I'm not sure it's the main valve to the water supply. It does go to the water heater so I'm guessing that it's it. Does anyone know anything about the main water supply valve and how to find it?
- The valve that goes into the water heater is usually the cold water into the heater. It will shut off all the water in the house, but to make sure you should turn off the main valve. If it's an older house, this the valve into the the heater is generally the main valve, otherwise it will be located near the meter and most commonly on the house side of the meter.
- Q: like they say on 4 strokes you gotta go get valve jobs, and they cost bout 300 they say? well what does the mechanic do? can it be done at home and your just adjusting them?
