Q:what is the function of varible throttle valve?
A throttle valve allows continuous control of the rate at which some fluid moves from a region of relatively high pressure into a region of relatively low pressure. An example would be in an automobile engine, where the throttle controls the rate at which air (at or above atmospheric pressure) enters the engine's intake manifold (near vacuum when the throttle is closed.) The throttle in an automobile engine is mechanically linked to the gas pedal (in case you didn't know).

Q:what does a Pneumatic valve do in a process?
pneumatic valve is nothing but a valve which is operated with the help of high pressure compressed air. the can be thought of as an alternative of a metal spring... These could retract valves more quickly and reduce the possibility of piston-valve interference as long as pressure could be maintained. Additionally, the amount of seat tension required to keep a coil sprung valve under control results in greater peak lift loading, with added stress to the entire valvetrain as a result.
Q:How can I fix my noisy tuba valves?
right this is what I did My truck is 2003 GMC sierra with approximately 112.000 miles that develpoed a noisy lifter. I asked around and offered a prior employer tip. This truck has the vortec 5.3 which I easily have study different posts that those autos tend to boost this equivalent style challenge. Pour a pair of quart of gas into your oil,particular I stated gas, run for 30-40 5 seconds. close off the motor this would possibly not restoration the challenge yet. . upload one extra quart of gas, permit it run 30-40 5 seconds close off the motor. permit stand 40 5 minutes to an hour The gas will injury down the gunk like no diverse. Drain oil and eliminate the filter out. What I did next replace into as quickly as positioned the oil plug in purely and added a pair of a million/2 of gallon of the pink potential degreaser down the hatch and permit that sit down for a stable hour. Then I drained it and guy did some nasty stuff come out. With the plug out I dumped one extra quart of gas down the hatch lower back to flush it. eliminate cap, dipstick and shelter the plug out and permit it breath for a staggering hour I switched to Valvoline synthetic mixture 5w-20 from pennzoil classic 5w-30 and have been given a wix filter out from a puralator. I stay in florida so I are actually not finding for the better weight oil. positioned the pug and filter out in, introduced the oil and ran the engine, in no longer as much as 30 seconds the noise replace into as quickly as long previous. I permit it run for slightly, close it down, then began the engine as quickly as extra in all probability 3 hours later The motor is whisper quiet, It hasn't run this quiet in years. wish this enables. i'm no longer particular if this attitude would artwork on diverse engines so use your judgement
Q:erg valve for 2000 honda accord vtec v6?
there was an extended warranty on the EGR valve to 8 years or 80,000 miles from new for problems related to insufficient lift of the valve because the port that the exhaust gas flows through gets plugged with carbon. if your car is within the 8/80 take teh car to a honda dealer for a free replacement of the valve and tube if you need to do it yourself or have someone else do it I can scan a bulletin if you want the details of how to do it. if you want that, send me an email by clicking on the icon above my name to the left of this answer and select email be sure to include your real email address that I can send an attached file to because Yahoo Answers doesn't allow attachments. Doing it this way keeps your email address and mine out of the searchable Yahoo Answers database hope that helps
Q:I plan on buy a BLOWOFF VALVE and woundering where does the BLOWOFF VALVE goes in my car?
Only TURBO engines have blow off valves. It protects the engine from over charging from high turbo charged ar pressure. If your is bad, it means that the diaphragm inside has ruptures. Many times there are repair kits with NEW diaphragm parts. LEARN form this. Only SYNTHETIC OILS that canhandle high temperatures can be used in your car. VALVOLINE will destroy your turbo bearings and blow youblowoff valve. Use Mobil One, Pentosin, or AMSOIL in there. THese oils can handlee the heat with NO breakdown, NO coke build=up, and NO oil feed or return line failure. STAy AWAY from wax based conventional engine oils. They are NO GOOD for your application if you haVE A blow off VALVE!!!!
Q:Valve job? Cheapest way?
Probably just the valve stem seals need replacing. NOT a entire 'valve job'. The seals help scrape oil off of valve stem to lower the amount of oil weeping into cylinder when engine is running or turned off. As the rubber ages, it cracks and loses its elasticity and doesn't wipe the stem properly. This is a lot cheaper versus a full 3-angle valve job which requires removal of the heads.. Get a second opinion.
Q:Heart Valves?
A good friend of mine ignored his bad cold symptoms and was diagnosed with pneumonia when it already affected his heart valves.
Q:Piece's of metal in my valve cover?
on the valve stem you have 2 keepers, they are small and curved and it could be one of them ! someone worked on that engine before you and either did not put both keepers in or one popped out !
