- Q: I was adding air to my bike tires and the valve became loose. Do I need a new tire or is there a way to tight?
- A Schrader valve coming loose is a rare occurrence. If you didn't damage anything and the valve core itself is coming loose, there's a tool to tighten them. Old-fashioned valve caps actually had this tool built in. You can still buy the tools for a couple bucks at auto parts stores. But of course, a new tube will cost about $3 and solve the problem.
- Q: i have a 1997 dodge avenger ES with a 2.5L v6. im wondering if my EGR Valve could be bad i get about 14mpg on gas. my car has a poor idle but will not stall idle gets kinda bad if the airconditing is on. I did a complete tune up and yes it was done right. and i changed my Idle air control valve. after i changed the valve i drove a few miles and i got a check engine light for insuffecient EGR flow but then it went away and never came back. I took the valve off and cleaned it with carb cleaner. im trying to find out why my ide is kinda poor and if the car sits a few days it takes a little longer to start.my motor has 142k miles but has been properly maintained.
- you might want to check you egr lines. they may be blocked. not just the valve. also check your O2 sensors and make sure that they are operating properly.
- 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: Hey guys. I need help. Sorry this might not go here... but i couldnt find a 'good' category to put it in. This is for an engineering project for college.Im looking for shielded core solenoid valves that can with stand 95-98% sulfuric acid. With this in mind not very many materials are usable, right now we are looking for HDPE (High-density polyethylene).The size of the valves and cost is unimportant. Main thing is finding someone who sells HDPE solenoid valves.For more clarification on what we are looking for, below shows a shielded core solenoid valve from ASCO. The more acidic resistant material they offer however is a FKM. Which can only withstand ~60% sulfuric acid solutions.
- In practice, engineers do not use solenoid valves directly on chemical or process lines. They are bound to leak and cause danger particularly in your case of 98% sulphuric acid. Use a mechanical valve actuated by a motor (since cost is no issue to you) If an air supply is available, then you can use pneumatic diaphragm valve operated by a solenoid valve. Motorised valve has slower fixed open close time VS faster adjustable open close time for air operated valves.
- Q: I have mitral valve prolapse and I don't get why only some people get chest pains? and what causes people to get chest pains with M.V.P (mitral valve prolapse), like me. PLEASE HELP!!!!!!!
- With MVP, your mitral valve is smaller due to extra tissue. This makes it a little bit harder for blood pumping through the valve to get through, which can often times cause an aching pain. As far as I've seen, this is not life-threatening and the pain can be treated with over-the-counter painkillers. Imagine you kink your garden hose while it is running. The water can't get through the hose and the pressure builds up. When you unkink the hose, the water flows freely. Your mitral valve has a permanent partial kink or blockage. The blood behind that partial kink can get blocked up and cause pressure in your chest. Be sure to get regular check-ups with your doctor, just to be sure your MVP is stable. Your doctor will also be able to suggest some pain remedies.
- Q: whaT ARE THE SYMPTON OF A BAD EGR Valve Position Sensor loss of power ?1998 toyota camry v6
- Typically when those sensors start to go bad, the EGR valve doesn't modulate properly between open and closed. When that happens you usually notice a sort of fluttering in the power delivery, often when cruising at a set speed but sometimes also when accelerating as a result of the wrong amount of exhaust gas being recycled back into the engine. You sometimes will notice a loss of power when accelerating as well. If the EGR valve is opening more than necessary it will be allowing more exhaust gas back into the engine than is beneficial....and that will reduce the amount of power the engine produces. If the EGR valve is staying closed more than necessary, you might not notice as many driveability issues but you'll probably notice your average fuel mileage decreasing a little and/or a check-engine light being triggered and/or a failure of an emissions test (even if the check engine light hasn't tripped) if you live somewhere that emissions checks are required.
- Q: What are the function of reed valves on a motorcycle?
- They allow a fuel/air mixture to enter the area under the piston in a two stroke engine on the compression stroke, as it is a one way valve when the piston is coming back down the gases are forced up through the tranfer ports into the combustion chamber.
- Q: need a different pump for? Is this some improvement on the old valve?
- There are schrader valves which are bigger diameter and are used also for automotive tires. They have a spring-loaded center pin that gets pushed down and opened when a inflating head is used. The spring is what keeps the air in the tube. The presta valve is the skinnier one. It does not rely on a spring to keep the valve close. The air pressure inside the tube keeps the valve closed. Generally, less expensive bikes use schraders while better bikes use prestas. All decent pumps have pump heads that accomodate both types. Either it is done by manually reversing the inside of the head assembly to change between presta and schrader or the head automatically adjusts or you use the appropriate one when the head has holes for both.
- Q: hi i just found out i have micro valve i and have allmost 30 years with willam sydrome any doctors know more what can happen what dose walking or others got to do with the valve will i stand for a longtime walk jump will one side get weeker then the other what about my hands and eyes my knees what will happend over the years when i get older ?
- I think you mean mitral valve prolapse. I have this. When I was younger I had a heart murmur and did several testing and nothing else became of it. Until recently when I was working out, I had pain in chest that didn't quite go away and went to the dr. and did some testing and diagnosed with MVP. Do not drink decaffeinated drinks b/c it will increase your heart palpitations. You can also be prescribe a medication to help with your palpitation. It's a beta blocker medication. It helps with your heart palpitations, but you should definitely go see another dr. if the dr. you're seeing is not very helpful or see a cardiologist. I was told to just go about doing normal activities.
- Q: I have varicocele and varicose veins. Both conditions are caused by vein valves becoming damaged or defective. My question is, is this a sign of more serious problems?Thank You
- No it seems to be genetic. The valves just aren't doing thier job and allows some blood to flow backwards . They are unslightly.The place varicose veins is deadly serious is the back of your throat. They are caused by scaring of the liver generally by alcholism
