Q:Explain terms associated with valve timing?
HI You answered it your self... exhaust valve opening (EVO) is when the exhaust valve opens.. and the same for the intake (IVO).. When the EVO happens the motor pushes the exhaust (burnt fuel) out of the motor when the IVO happens it sucks gas into the motor to get burned and make power.. Exampe of a 4 strock motor. 1) piston goes down , sucking in air and fuel (IVO) 2) piston goes up compressing the air and fuel spark plug fires ignighting the fuel 3) piston goes down turning the crank powering the car from the explosion of Fuel. 4) piston goes back up pushing the spent fuel out. (EVO) then repeats. On a 4 cylinder car this happens 4 different times on an 8 cylinder car 8 different times and on 6 cylinder car 6 different times. When one cylender is firing another well be coming up to push out its spent fuel and another well be going down drawing in fuel and so forth.. good luck tim EDIT IVC = intake valve closes EVC= exhaust valve closes
Q:they say leaky valve now what ?

Q:How to control fluid flow through a valve automatically? What are the circuit requirements?
Some valves are controlled to maintain a fixed pressure on a system. Others control the level in a tank or vessel while still others actually control the flow rate in a pipe or line. The automatic control of flow through a valve requires a sensor to determine if flow is needed or what the flow rate is. You then need a controller to take this input and then adjust the valve to achieve the desired result. This is called a control loop. Some are all electric/electronic while others are all pneumatic. The valve itself is a specific valve designed to perform the function intended. It is not a good idea to take an existing on/off valve like a gate valve and try to control flow. These type of valves do not have a flow characteristic that is proportion to valve opening while a control valve does.
Q:how does a guitar valve amp work?
Most valve amps I have used reproduce the sound of a tube amp. Tubes have a warm sound and can be overdriven to get that good rock crunch distortion sound. We went to solid state because they were durable and didn't require the maintenance of a tube amp. Printed circuits and transistors cut the cost of manufacturing. The old tube amps still have the purpose and they never quite matched the exact sound of tubes with the solid state amps. That is why they are making a lot of tube amps now.
Q:setting valve lash and proper method?
Just read this again last light. The motor should be hot an normalized before you start. With one valve cover off clean the cylinder head of all old cork gasket residue lay a new gasket on the head and screw the valve cover bolts through the gasket into the head a few threads. There are companies who sell neat little clips that slide on the push-rod end of the rocker arm to reduce the leakage of oil from the push-rods through the ends of the rocker arms. We're going to hear all sorts of whining and disagreement here but Chevrolet hydraulic valve lifters must be adjusted with the engine running. It's written in a factory overhaul book. The oil pressure from the oil pump has to adequately pump-up the hydraulic valve lifters so you can get proper adjustment. Using 3/8 a deep well socket and a long extension, loosen counter clockwise the center rocker-arm nut slowly till you hear the rocker arm clatter. There's two trains of thought how and why the center not should be adjusted. GM says to *very slowly turn the center nut till the clatter disappears. Slowely continue turning the center nut 3/4 more turn clockwise. William Tyler Grumpy Jenkins (Chevrolet race engine builder) always said to turn the center nut to stop the clatter plus 1/8 of a turn more. He did this so the plungers inside the lifters were extended nearly all the way out. This was done to reduce hydraulic lifter pump-up and valve float at high RPM. For the detractors who don't think this is correct, pull the valve covers off a 265, 283, 327 or a 350 with hydraulic lifters after the engine has been off for 30 minutes. You will see every rocker arm is holding the valves in the closed position. It's impossible to adjust the valves with the engine off.
Q:I need help with my trumpet/cornet valves?
I play a baritone, but I hope I can help. On my instrument there are little notches at the tops of the valves. I had to spin my valve until I heard a slight click then I would push down on the valve to make sure it worked. (I would start on the first valve) Then to make sure that I had it in right I would blow in the instrument to see if the air went through the holes. Try that, it might help. Also, the next time you take your valves out keep them in order and in the position they came out in.
Q:Which is the intake and which is the exhaust valve?
the intake valve is usually bigger and on the left. the exhaust valve is usually smaller and on the right. at least it is true in small engines (lawnmowers).
Q:Warped valves on my car? ?
You need a new mechanic. Valves don't warp. They bend from hitting something or burn but not warp................
Q:how to loosen a ball valve?
tap it lightly with a hammer while turning it
Q:Biological or mechanical heart valve replacements...?
Well one of the draw backs to a mechancial valve would be that your friend would have to be on blood thinners for life. Biological, you would worry about rejection. But, you would worry about rejection with the mechanical also. Depends on what type of after care he/she is willing to put up with. I would probably choose the mechanical.
