- Q: Surly Pilots don't just switch the fuel selector valve of mid flight
- Not to take away from JFK jr's piloting skills but the possibility exists that he failed to check to see if the fuel valve was on in the first place. I do not know how far along in the flight he was, but a typical piston engine plane can get you up and on your way with the fuel that is in the fuel system. Why I know this, my flight instructor while training one of his students died in a forced landing due to engine failure because the fuel valve was not turned on. My flight instructor would allow his students to perform the preflight on there on, of course after many hours of dual training. The plane was a piper four place, it made it to about 400 feet agl before the engine stalled from fuel starvation. The irony of his death was from complications on the operating table from a broken ankle and a blood clot that broke loose. Checking for the on position of the fuel valve is on the check list. During emergency landing procedures, one of the functions is to turn the fuel valve off to reduce the possibily of fire. This doesn't answer the question but is a possibility unless of course he was well into his flight before the accident, in which case he probably moved the fuel valve to the off position following emergency procedures.
- Q: non-return valves
- ..?..non-return valves..? I will assume that your 'non-return valves', are what is also known as check valves. Check valves allows flow in one direction only. These are used wherever you need to prevent backflow into the system, or to maintain a charged circuit with fluid, until you choose to unload(depressurize ) it. Now, why are they used in discharged lines of salt water, basically to prevent backflow....reason not known, here , requires usage info.
- Q: How do I adjust the valves on a 96 Blazer, 4.3 V6? When we tighten them to torque specs there is no compression, then when we loosen them and get compression, they loosen up to loose after its been running...any help!, THanks!
- i think the older chevys, you could adjust the valves, but i think now they are self adjustment. what you do is take no:1 rocker and turn the crank, until its all the way down on the low cam and then torque the bolt to specs, do the rest the same way. but if they are adjustable, start your blazer and loosen the rocker until you hear the lifter, then tighten it until it stops, then give it another 1/4 to 1/2 turn more. do the rest of them the same way.
- Q: I have a 96 Toyota Camry. I am putting about 4 qts. of oil in it a month. Other than this issue and some other minor things this car is in great shape. It doesn't appear to be smoking from the tailpipe and I never find any puddles of oil under the car after it has been sitting in one place for a while. What can be wrong with my car causing it to eat this much oil. Every now and then I smell a little burning oil but it is not coming from the exhaust. I'm thinking a valve job. Engine has 250,000 miles on it and it runs great other than the oil thing. I drive it 116 miles a day back and forth to work. Any suggestions??? Help!!!
- A valve job is removing the cylinder head(s) from the engine so the valves, guides and seats can be refurbished to restore compression and oil control. A valve job may be necessary by the time an engine has 80,000 or more miles on it, or to fix a burned valve, compression or oil burning problem. If the valves are to be reused, they will be inspected, checked for straightness then refaced. Many shops automatically replace all the exhaust valves to reduce the risk of failure (exhaust valves run much hotter than intakes and are much more likely to fail). On the other hand, if you have an import car with dual overhead cams, four-valves-per-cylinder and a lot of fancy valvetrain hardware, you might be looking at a total bill of $200-$300. Parts typically cost much more for import engines as well as performance engines and diesels. The labor to do the valve work is also much more involved on these overhead cam multi-valve heads. (Of course, they didn't tell you that when you bought the car. All they stressed was the fantastic performance of overhead cams and multiple valves.)
- 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/alfier... 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...
- Think of an engine as an air pump - obviously, we want the least amount of restriction for the incoming air and also the least amount for exhausting the compressed air. The ideal situation would be to remove the head during the intake stroke and put it back on during the compression stroke, but, obviously, this isn't possible. On a naturally aspirated engine, the intake is the most critical because the air is moved only by a relatively small difference in pressures. The exhaust stroke, on the other hand, is aided greatly by the super heated temperature and rapid expansion of the gasses. Two intake and one exhaust valve seems to be the most practical and efficient solution - adding more vales means smaller valves and an increase in the overall complexity. I seriously doubt that Maserati ever abandoned ANY automotive idea due to cost restraints. It's far more likely that adding more valves than three or four simply resulted in diminishing returns. Sometimes the allure of a new buzz phrase is nothing more than a marketing ploy - a 16 valve, DOHC, four cylinder engine, for example, is a pretty impressive resume for an engine, regardless of whether it actually is the optimum performance set up or not.
- Q: I play the trumpet and I took it home for Christmas Break. On Friday I am playing Amazing Grace at Church for New Years Eve, but the problem is my valves on my Trumpet is sticking and I don't have any valve oil for it. Is there any other oil that I can use for the Valves? It will be really great! Thanks :)
- valve okorder /... its simply the best
- Q: I have mitral valve prolapse, I want to continue lifting weights.. Can i lift weights?here's my latest echo result.1. Normal left ventricular size with non-thickened walls with adequate wall motion and systolic function (EF = 70%)2. Normal left atrium without intracardiac thrombus3. Normal right atrium, right ventricle, main pulmonary artery and aortic root dimensions.4. The anterior mitral valve leaflet prolapses into the left atrium during ventricular systole.5. Structurally normal aortic valve, tricuspid valve and pulmonic valve.6. No pericardial effusion noted.COLOR FLOW DOPPLER STUDY:No abnormal color flow display across the valves, interatrial and interventricular septae.Normal pulmonary artery pressure by acceleration time.
- overall picture doesn't prevent you from doing mild to moderate exercise, but with wait lifting we should think twice.
- Q: Grade seven, my teacher's a pain. She didn't even explain the 'sets', we just know what valves are in general. So.. which set of valves closes when the ventricles contract? Relax? Thank you so much!***10 POINTS***
- There are two types of valves in the heart: the atrio-ventricular (AV) valves and the semi-lunar valves. There are two AV valves: the tricuspid between the right atrium and the right ventricle, and the mitral (also called bicuspid) between the left atrium and the left ventricle. There are also two semi-lunar valves: the pulmonic semi-lunar, between the right ventricle and the pulmonary trunk (artery) and the aortic semi-lunar, between the left ventricle and the aorta. During diastole (the relaxation phase), the AV valves are open and the semi-lunar valves are closed, so the ventricles can fill with blood. During systole (the contraction phase), the AV valves close and the semi-lunar valves open so the blood can be pumped around the body.
- Q: Water is seeping up around relief valve threads. Tried tightening but could not get it any tighter.
- Is the valve open? If not - i'd open it - the strain of the tank is forcing water out around the valve - with the aid of opening the valve you're going to relieve probably the most pressure. Additionally - turn off the energy and phone a plumber in the morning- your hot water tank can blow up - no longer just right.
- Q: where is the heater control valve on a 1996 volkswagen passat
- There is no Heater Control Valve. Coolant circulates through the heater core continuously. Air flow is directed through the heater core/ac evaporator in the air distribution box under the dash as required by user input. If you have no heat, there are a couple of things that could be wrong. A bad water pump, plugged up heater core, bad blend door/cable, bad Climatronic control head, or a bad actuator/motor. So, what's your question? What is the car doing/not doing that you think it should/should not do?
