Q:in engines otto cycle: Larger valves will allow more volume in and out of the motor. While this does produce less HP in some cases, it in creases torque on the bottom end.

Q:The Hawker Tempest was the fastest piston powered airplane ever made, it had a sleeve valve engine. It was made obsolete, by the Me 262 and other jet engined fighters, But it's engine was the ultimate piston aircraft engine. Then piston engines became something for inexpensive planes, but why has the sleeve valve not undergone further development as a sports car engine?: this has been tried and failed miserablly mainly due to cost they ran a steel sleeve in a aluminum block and due to the differences in cooling the engine was subject to failure within 30,000-40,000 miles

Q:whats the location of the pcv valve on on a 2001 bmw 740il (e38): In front of the engine slightly to the left and lower area of the throttle valve. It is a round black plastic canister supported by a teardrop shaped rubber with a cable connector at the top and 2 hose connections at the opposite end of the cable connector which are perpendicular to each other. BMW calls it the tank vent valve.

Q:Yesterday，my friend told me his ball valve in garden was broken. He want me to help he find a useful ball valve. I find some webs, but not he want. So I want somebody to help me find the useful ball valve. Thanks.: Hi here in the united kingdom the only place you would find a ball valve is in a tank like a header tank in the loft or in a toilet. then it would be a low pressure one or a high pressure one. what you have described sounds more like a stopcock which is a tap to switch off the main water supply to the property. which you should consult the water company about as it maybe there responsibility. so i would consult with them first.

Q:i dont get how valves produce the sound? and why did we change to solid state? was that because they we're used in stereos?: 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:I'm going to replace a valve guide and wondering how I should do it.Should I drill into the existing valve guide to the point it's small enough to pinch with some pliers and pull it out?When I put the new one in, should I use a wooden dowel and an air nailer to pound the guide into place?The more info. the better. It's my first time doing this.Thanks!: Ohhhh man. NO DRILLS. I assume you are referring to an Aluminum Cylinder head. To do it correctly you need a drift punch that has a pilot size of the valve stem, and an outside diameter that is just a few thousands smaller than the guide. Disassemble the head completely, put in Moms oven at the highest setting it will go to ( 5-6 hundred degrees ) Pound old guide out from the combustion camber side. ( have every thing ready to go this FFer will be hot ). Coat new guide with something like STP, put in freezer, carefully align it, then slam it home from the valve train side, don't pussy around, get it in before it attracts the heat of the head, if you stop or it stops you will have to repeat the entire process. If you gall the Aluminum ( say O-**** ) Since you have to hit this thing fairly hard you will need to refinish the inside of the guide with the appropriate reamer. Then refinsh Valve seat ( they never, NEVER line up perfectly )

Q:I have pressure steady at 13psi --- water temp is normal range but the external emergency run valve has been dripping since i turned the boiler on this year? Expansion take was empty, so I forced water through and then drained it and reopened the valve.....I am stuck and getting concerned. Anyone have a suggestion?Would really apprecite it?Additional info:Boiler is a Gas Powered unit by MASTER from the 80's.....: The TP valve will naturally wear out over time, if it has never popped open the washer inside of it has hardened, when you opened it it didn't seat properly when it closed back up, causing the drip. This is not an unusual or dangerous condition, the TP valve will usually wear out before the boiler does, it can be quickly and easily replaced. The valve will still function with a leak, but this reduces the efficiency of the boiler. DO NOT, under any conditions, DO NOT plug the leak by plugging the opening on the valve, this creates the potential for a very dangerous condition, let it drip until it can be replaced.

Q:What kind of valve is on this tennis ball cannon in this picture?: describes how it works pretty well even thought this one is not in fact solenoid operated. This one is operated manually via the blow gun which is just being used as an inexpensive lever operated valve, but the main part of the valve works on the same principle illustrated in the Wikipedia article, just mentally replace the solenoid with the lever valve.

Q:I opened the OPD valve on the BBQ propane tank and propane spray out, I have heard that propane should come out only when it is hooked. Is there something wrong with the propane tank?: extremely tough stuff seek onto yahoo that will will help

Q:will adding a bypass valve onto an air filter effect gas milage or horsepower?: bypass valves are for cars with forced induction IEturbocharger,supercharger it allows the air that would normally be expelled into the atmosphere blow off valve and instead putting it back into the intake which helps with less lag in building boost again. If your car is not turboed or supercharged then forget it.
