View The Full Version : Info about exclusion egr
Hello there I ask you of the forum for an opinion on a speech that at times creates discussion with my partner....he argues that the exclusion of the egr valve on cars that are equipped with fap/dpf is not a proper operation and is pi? problems than gains.ie, to his words l exclusion lengthens the time of regeneration and the amount? of regenerations.I'm rather of the opposite opinion....on my 159 2.0 jtdm not l I is still closed due to this reason....but you say to me?
I had heard also I this thing and ****llo theoretical ? correct why? the egr is used for the regenerations of the Dpf. I personally have done some of the car excluding the single egr problems, she related leaving the dpf active and I had no problems with regeneration or something like that perhaps the time you will be able to stretch but it does not involve problems that cannot regenerate.
in truth? the exclusion of egr leads to an increase of the temperature to which the regeneration takes place in less time . The cadence of the same remains the same why? depends on the pressure differential determines the percentage of the blockage.
close safely to the egr , you have only to benefit from it.
I can not attach specific documents, but your colleague has reason...
The strategy by which you regenerate the fap also contains the shutting of the flow of exhaust through the egr valve..
And not ? true that the exclusion of the valve results in an increase of temperature..
On the contrary, ? just the opposite...
Hello, I believe that the speech should be set for the specific type of car, and then also as a hw and sw, many of the cars to the closing of the egr will only result in benefits over any other type, some of the vw group type vehicles equipped with ecu pcr 2.1 if you exclude the egr the car locks the regenerations, and therefore clogging of the dpf.........On your alpha you will have only benefits............
On the PCR block the regenerations?
This ? beautiful..
on some sw that happens and you still don't understand...............
Let's just leave this topic
Let's change the topic I mean
no ok,then the only exclusion of the valve and to evaluate the time depending on the ecu....ok,I know on mine it will only even why? strattona a little bit just a medium load when the valve is working more?,it certainly is a problem in the egr already tried it on other....now I see it with the sw
I wonder after the elimination of the egr valve the exhaust gas is not brought back more from the egr valve in the intake is not going to clog up the first in fap, with the consequent increase in the number of regeneration ?
egr valve closed equal less smoke, so in reality the maximum is expected to decrease the number of regenerations
maybe he's right exelion 1986 the car without the egr uses more pure air, with consequent decrease of gas but this can not be if not, that they made it to do ?
the egr actually serves to lower the temperature in the combustion chamber so as to decrease the production of oxides of nitrogen that are formed precisely at high temperatures
this unfortunately leads to a combustion of the worst, with the consequent increase of the smoke
guys I'm not there I'm understanding nothing too many statements opposing I'm going to document myself and I want to know
Franco, the egr is the classic compromise that has to do with the laws for the abatement of emissions of nitrogen oxides and the manufacturers that after the warranty period must intervene heavily on the damage that leads to ( clogging of the intake manifolds, dirt and obstruction, valves, locking valves, swirl ).
Deleted ( closed ) egr the engine thanks and the problems disappear.
The fap/dpf is not affected in the slightest of the closing and, if electronically done well, it will not interfere with the regenerations, nor with the whole and also the performance and power consumption benefits.
I think I figured after the off the egr you need to monitor for a bit of time in the car to see the effects
The elimination of the EGR Valve takes away (according to law) the range of the EURO for the car, then we are on the "illegal".. and the same thing with the elimination of FAP even if, in the opinions of experts is quite demonstrated that the FAP all do except clean the exhaust gas, on the contrary.. it just makes more dense the dust that we breathe, limiting the capture phase of breathing, and then it is only a move business to the detriment of the health of the planet (as always).
Going back to the EGR, obviously, as well as the fact of limiting the maintenance of the car since you "attoppa" more frequently, a bathroom of a bar, I STRACONSIGLIO!
I have personally plugged the valve upstream and downstream of the engine and I made a review without problems.
considering that this is a very fair response
