Problems with EGR valve

As I said before, I respect any opinion, but there is where a professional diagnosis differs from something empirical. Each person works as they want,
greetings.

The idea as it says short circuit is to help and give the opinion not to fight between us, each country works with different laws and that is fine to say about it, but what interests you is an opinion or a slightly more scientific explanation is easy to do, what the EGR really does in a vehicle is to recirculate the exhaust gases, this does so in order to optimize the air temperature for a better and faster combustion Importantly, at the time of exporting the engine, it is said that the function of this valve is to lower the contribution pollutants and somehow also performs it, but this is not its main function, you have to take a little care with the literature that we find on the network because, in some cases it does not provide the vertid information and we should make a mortgage on our own account, if you check the function, the time and the way of work of this It is the real function that it fulfills, in addition to a chemical theory it is not very decisable or viable, that the combustion gases are burned again because they are recurd of an anterior combustion and will not help in the oxygenation of the Nuava Mescla, since the residue does not meet any link in the fire chain. To minimize the impact to the environment, they would be passed by a water capacitor and mesheed with it to catch these pollutants, the problem is that this water when dry or evaporates would leave the pollutants in a state of dust to the pollutants that would have what would be more harmful than in its gaseous form. Well, investigate a little and you will realize what I say, greetings and keep the good treatment and dispose of thanks.

wave, the alvula cannot be canceled, you are going to Hod the car, it lips with gasoline inside and you give it well, you have to take away all the shit from inside, if it does not change it

Hello everyone, thanks to the comments that I have been reading these days and what I have been reading I get an idea of ​​operation, I even clean the cancellation of the EGR.
I believe that the idea of ​​ending the escape gases produced by combustion is good, but not in the way the engineers have devised since I believe, that gase recirculation must fulfill two functions: the main one, which is to avoid that 100% of the exhaust gases go abroad, that if it fulfills it, to the detriment of our engines that are filled with dirt and the second to help the new combustion reducing the new combustion to Produce the explosion, I don't know how it achieves when the exhaust gases come out at more than 1000 degrees, apart as Kikemec says, how do you get burn to burn gases since burned and if you get it, they will not be more pollutants than before? Also add that the valve is designed to act allegedly at low and medium power since in high regimes engines need fresh air. This means that the engine at full power does not contaminate? Man I believe that avoiding the pollution produced by escape gases is a very difficult task and that the brain will have to squeeze more to solve the problem. At the moment for me they have chosen the easiest path, but to the always detriment of the users, that we always go as a breakdown in fault and that so far, do not solve the problem. My question is: when using this method they have thought more about the environment or the benefits they get cleaning or changing the damn valve.
I am wrong but it is what I feel.

Hello, outside of avoiding toxic gases, the EGR with the feedback of combustion gases maintains the temperature of the combustion camera (cylinders) and the combustion is even, the engine works soft.
If it is electric disassemble and activate it directly with 12 V from a source of power or battery. ROCIALE WITH AN PRODUCT TO DECERBONZAR CARBURATORS LIKE THE MTX OF LIQUIMOLY THAT IS WELL WET AND LEAVE ANY HOUR THAT IS REMOVED, LAUNCH, LAUNCH WITH CLEARGING AND THEN AIR AIR AT THE PRESSURE AT THE VALVE. The test is simple, it has an input and an exit, blows through it in off -Condition and the air does not come out, it passes on on 12 volt and opens like the water llava and lets everything happen.
It usually has a connector with 5 contacts: two for active EGR and three others for an approx 5 kohm potentiometer that varies its value with the change of status of the valve about 1 kohm. The car's compirator usually feeds it with 5 VDC.
If the egr is pneumatic, soaked it with liquimoly and you then apply empty.

If you leave it outside the EGR the catalyst will last quite less, you will have temperature problems and you will see a shiver and disappeared especially in summer.
