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:First trumpet valve always gets stuck?
You need not replace the valve, but it does need a bit of attention. There are many possible reasons for the sticking and you can spend a long time trying to chase them down. Inconsistent sticking suggests 2 likely reasons (there are several more possible reasons). The first is piston wear that has slightly misshapen the valve casing so it sticks because it doesn't travel through the valve casing exactly the same way every time. The second is that the felts and corks are worn and need to be replaced. The best thing for you to do is to take it to a shop, describe the problem and spend a few bucks to get it fixed right.
Q:Honda civic VX.. how many valves?
'92 Civics had single overhead cams (SOHC), so they have 8 valves. 1 intake valve and 1 exhaust valve per cylinder, so since there are 4 cylinders, that makes 8. Vehicles with dual overhead cams (DOHC) had 16, but Hondas had SOHC cams at that time. I'm really surprised how many people are saying 16. That is incorrect. I am positive. You cannot have 4 valves per cylinder (total of 16 valves) on a motor that has a single overhead cam.

Q:Question about my bicuspid aortic valve?
so, as you already know, a typical aortic valve has three cusps. yours has two, so this is a structural issue. the point of these cusps, or leaflets, is to maintain blood flow in the appropriate direction through the heart and to the rest of the body. having a bicuspid aortic valve can be something that you inherit from one of your parents. did you have a murmur that prompted them to look for it? if your valves are young and healthy, there's probably not a problem. when it can become problematic is with age, where the leaflets can become calcified and hard, then they can not open as well (i.e. become stenotic), or not close properly (i.e. become regurgitant). if either of these two things develops, and becomes bad enough, they consider valve replacement surgery. but this is the kind of stuff that happens over years and years. you should see a cardiologist, if you haven't already been referred to one, because this is a medical condition that gets watched over time, and then if it gets bad, it gets treated. while it's not bad, it gets watched. this cardiologist will follow you over time, in addition to your regular family physician. he/she will also be keeping an eye on your aorta (the big vessel that blood enters after it goes through the aortic valve), because sometimes people who have bicuspid aortic valves also have problems with your aorta. i would also talk to your cardiologist about whether or not you need to take antibiotics in advance (i.e. prophylactically) of any dental work. i.e. because of your valve with a different shape, are you more predisposed than the average person to getting an infection there. but go to cedar point if you're young and healthy. a roller coaster should not give you any sort of problems. enjoy yourself!
Q:Whats the difference between Steam and VALVe?
I don't understand this question fully, but I think you like my answer: Steam is a software for gaming articles, but it also meaning gas on another word. Valve (www.google.rs/search?q=Valvehl=srclient=firefox-ahs=SCurls=org.mozilla:en-US:officialprmd=imvnssource=lnmstbm=ischei=8zHfTr2iIsKnhAeTy-yVBQsa=Xoi=mode_linkct=modecd=2ved=0CCgQ_AUoAQbiw=800bih=393) is a legal company, same as meaning the link I put there. Hope it helps! :)
Q:what is the difference between a pressure control valve, a temp control valve, and a flow control valve?
In principle all valves are flow control valves. What changes is the variable they are controlling. A temperature control valve controls a flow to heat or cool another fluid. A pressure control valve, controls a flow to maintain the pressure in a vessel. As pointed earlier, valves can be self contained, i.e., the sensor is part of the control mechanism, usually a diaprhagm which moves the valve stem. and a spring to adjust a set point. Or, they can be pneumatic or electronic, in which case there is an external power source, transducer and controller to adjust set point, gain, reset and rate. This gives additional flexibility, if needed, depending on the process to be controlled. .
Q:Cannoy identify what kind of valve goes into my old valve guitar amplifier?
I never considered VOX a crunchy amp, has more of a jangle sound to me. Not sure what wattage you are looking for. In my opinion you don't need many watts in a class A tube amp. I heard an Orange Tiny Terror through a Marshall cabinet recently and it was awesome. I am considering that head with the Orange 2 x 12 cabinet. That head is only 15 watts but man is it loud...and crunchy.
Q:What would happen if a PCV valve disconnects while driving?
in the short term, use a plastic wire tie to secure the hose until you can buy a new hose....you need to replace the hose.
Q:Multi valve engine advantages?
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?
