- Q: so do v-6 engines mean 6 cylinders right?, but what are valves? sometimes they are like double the cylinders (12 valve v6). what do they do, and cars that have like 2.5L does that mean how much fuel is injected and does more mean more power?on a side note, what kind of engine is the evo x? is it 4 cylinder? but has really good technology in it and is that how it has such high bhp?also if anyone knows, i kinda know what torque is but can someone explain in laymen terms? does more=better?
- Yes v6 means 6 cylinders (pistons). Each pistons need to have gas come in and out and so the valves open and close to do exactly that (breath). There are at least 2 valves per piston - one (set) for exhaust and another for intake. Sometime to make it breath easier, there are 2 valves on each set. The 2.5L mean 2.5 liters (the measurement of the pistons) or basically the engine. The larger the displacement the more powerful (theoretically). Of course the larger the displacement the more fuel need to be injected. The exception is TURBO charged engines which stuff extra air (and extra fuel) so even a small engine take more fuel than equal non-turbo engie. The Evo uses much more than high tech engine to be that good. Besides being powerful, it uses the computer to divide the power to all 4 wheels in such a way to keep the car pulling even in a hard turn. === The TORQUE is the actual measure of engine power. The horse power is a translation of torque into something that people understand (horse - power). Good Luck...
- Q: Im trying to replace the egr valve on a 97 lincoln continental. I need to find out what size wrench I need, to get the nut off. Do you know?
- I am assuming you want to replace the EGR valve because you are getting an insufficient EGR flow trouble code. Before you replace a perfectly good valve with an inferior aftermarket part that will likely fix nothing, a little more diagnosis is in order. If you have access to a scan tool and a vacuum gauge, perform a KOER (key on engine running) test on the engine with the vacuum gauge connected to the hose to the EGR valve. When self-test reaches the EGR test, look for the vacuum guage to move during the self test. If it moves, the vacuum source and EGR solenoid are good. If not, trace the vacuum harness for leaks. Without the scanner and vacuum gauge, find a length of hose and suck on the hose, or connect to other vacuum source to test the valve. You are looking for an RPM drop at idle when you open the valve in this way. I suspect your problem is a passageway clogged with carbon. Remove the valve and throttle body to access the clogged areas and manually decarbonize. This is the most common reason for an insufficient EGR flow on a Lincoln, along with a faulty DPFE sensor or related hoses. My money is on the clogged passages or the bad DPFE sensor.
- 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.
- The EGR must be closed at idle and open as you cross quicker. If your EGR have been caught closed, it could don't have any final result on driveability. If your EGR is caught open, probabilities are it in most cases may not idle for lengthy earlier than dieing. I could blank the MAF sensor placed simply after the air filter out. Use BrakeClean spray. You did not say whatever approximately the gas injectors. I could placed an injector cleanser within the tank (it would possibly not support however its inexpensive than exchanging them). You would dispose of the spark plugs and notice if any seem discolored indicating a persistant pass over. This would point out the cylinder or cylinders with disorders similar to plugged injector, dangerous coil, something.
- Q: Water has been seeping out of the sprinklers closest to the anti-siphon valve. Water seeps out of the sprinkler even when the anti-siphon valve is manually closed and not connected electronically. I opened up the anti-siphon valve to inspect the diaphragm, but there is no debris nor it was damaged. To be sure, I switched the diaphragm chamber of the two anti-siphon valves (a suspected leaky one and another good working one), but leak persists from the same sprinklers. I think the leak is from the (float?) rubber seal at the bottom of the stem closing the inlet valve. My anti-siphon is a Hardie (or Irritrol) model 311A series.1) Is my troubleshooting and logic correct? What other components could have contributed to the leak described? 2) At what scenario will water be flowing out of the anti-siphon cap?3) How can I determine if my anti-siphon valve has a vacuum breaker? What is a vacuum breaker good for?4)Which brand makes the most reliable anti-siphon valve?
- I work in a printing plant,and our city mandates anti-siphon valves on all our commercial equipment,so I have a little knowledge about these.We used to call these pesky creatures Vacumn Breakers,but now they are called anti-siphon valves,but what's in a name-they both are supposed to accomplish the same thing.Should your water pressure drop,due to a broken main or largefire,these devices are supposed to prevent contaminated water,like the contents of the Agfa Encomatic plate processor rinse tank,or your irrigation pipes,from being pulled back into your plumbing ,and then out your faucets when pressure is restored ,which could make everybody sicker than pooches. The way these work on industrial models is a little more complicated,but the principle is the same,for water to flow through the system,a certain pressure must be maintained.Our older models had a spring and diaphram arragement,the water pressure pushed the diaphram against a seal seat,with a spring behind it.As long as the pressure in the valve was greater than the spring,water would flow through the vave,but when the pressure ceased,the spring closed the diaphram,which in turn opened a vent that allowed the water to drain hence,vacumn breaker.These had to be at a point above the turn-offs,by the way,and when they malfunctioned,due to debris or rusted springs,they could either fail,and stay open,or fail,and water wouldcome gushing out the cap. The conditions you desribe sounds like a low pressure situation,where there is not enough pressure to flow through the anti-siphon.Is your supply line kinked or crushed?
- Q: For a project I need to know the ingredients of a product I use and I decided to use valve oil. All it says on the sticker is petroleum distillates. Can someone give me the ingredients? I need it to have atleast 5
- Valve oils use proprietary formulas so it is unlikely you will be able to find out an exact composition. The basic ingredients of petroleum (as opposed to synthetic) valve oils are light machine oil (kerosene), mineral spirits and fragrance.
- Q: where is the shuttle valve located in 03 land rover discovery hse ?
- The shuttle valve is a part of the brake modulator this problem is addressed by the replacement of the brake modulator and that's a $1,500.00 dollar part plus labor but I believe that they sell a shuttle valve repair kit for around $100.00 dollars.....
- Q: i know its going to drop some oil, im just wondering to what extent? how much oil is going to spill out?
- If your asking if the Valve cover will be full of oil..... No it runs back into the oil pan. There will be oil residue inside and it might drip a tiny bit when you remove the cover but.....
- Q: Is it hereditary? My dad had a bicuspid valve and we got told it was hereditary but some doctors say it's not, my parents wanted to get me tested in case i had it so we would know in advance but the doctors here refuse to do it (I live in England if that makes a difference) my dad said he would pay to go private if it's hereditary. I know someone who had a bicuspid valve and 3 out of her 4 children inherited it, i know it's pretty harmless until i reach an older age but my parents and i would like to know now, i'm 13 by the way.=]
- About 1-2% of the population have bicuspid aortic valves, although the condition is nearly twice as common in males. It is more common than any other congenital cardiac anomaly. Bicuspid aortic valve has been found to be an inheritable condition, with a demonstrated association with Notch 1. Familial clustering as well as isolated valve defects have been documented. The incidence of bicuspid aortic valve can be as high as 10% in families affected with the valve problem. Other congental heart defects are associated with bicuspid aortic valve at various frequencies.(Wikipedia) The cause of this problem is unclear, but it is the most common congenital heart disease. It often runs in families.(MedlinePlus)
- Q: Im 17 with a Bicuspid Aortic valve and hypertension (around 160/85). Only other family member with teenage hypertension is grandfather. Im on 2 different types of hypertension medication which only brings blood pressure down to 138/75. It still jumps to 157/85 on medication. I have leakage of my valve that has not gotten worse or better since starting the medication (first checked in September, medication started in Novemberish, now April). No stenosis yet. Any idea what im looking forward to in next couple years? Or is this stuff spontaneous?
- Could go either way. since you are on medication, could be the leakage is contained.
- Q: as we are strating centrifugal pump with discharge valve close and can not start positive displacement comp. with disch. valve closed
- No, with no discharge flow, there's no suction flow the compressor will immediatley go into surge. However, if a Low-Flow recycle control is installed, upstream of the discharge valve (which should recycle back to the suction drum to prevent heat build-up), then the compressor will operate without surging and without lifting the discharge safety valve but the condition should be corrected ASAP. (A Centrifugal Compressor will normally be fitted with a Low flow recycle system taken off from the aftercooler discharge line for use during start-up but, if a sudden low flow condition occurs and the recycle doesn't have time to activate, a Low Flow alarm and trip system will shut down the machine). Also, starting a centrifugal pump against a closed discharge is quite common practice as long as it too has a low flow protection recycle back to the suction vessel. This Low flow recycle is common where the discharge has a liquid level or flow control valve installed and may close down during normal operation. This valve would be operating as a 'Split System' controller in conjunction with the Low-Flow recycle control valve. PD pumps without discharge pressure safety protection should NEVER be started against a closed discharge, the hydraulic pressure build up will be instantaneous with possible disastrous results or stalling of the pump.
