The tube rod clearance is usual: 1mm

Hello everyone

from pitmix
Hello
What are your temperature values ​​on the WV RolCopter?
You may have the same problem as me.
I have not yet had time to consider the matter.
I assume that it is a problem of restriction of the too important conduit around the rod.


The tube rod clearance is usual: 1mm

good evening everyone
It's amazing that it doesn't heat up, despite my engine being under-exploited (and it's a diesel that heats up less), the presence of the turbo which causes a loss of around 100 ° C, I manage to get enough heat.


TDI therefore a turbo which takes its share of heat, and the reactor which is placed in what was a catalyst at the origin therefore a lot of space around. I measure the temperature of what should be GEET gases on a nozzle just before the turbo.

Bonsoir
RolCopter may be the distance between the reactor in the old catalyst and the turbo that is too large and lets the temperature drop. My very first assembly was a derivation of the exhaust under the car and I did not have enough heat I had to put the reactor just behind the turbo and preheat the air intake to have something. So with a higher yield TDI it should be even more restrictive ...
It might also be necessary to isolate to improve the system, this is also my case.

Yes I am well aware of the fact and in addition there is too much space around the reactor, but still I had hoped for a rise in temperature and the I see only the rise in temperature around the place of the measurement (tapping) and not of the flow measured in the fitting, this is at least what I suppose given the low elevations which are related to the outside temperature.

hi rolcopter

you know if you put your reactor in the glove box it won't heat either.

we are some on this forum to explain how to operate a pantone (info that is spun generously and free of charge to keep the process moving forward) obviously if you do the opposite of what andré, calmel michelm etc .... do it is not sure to walk the first time.

@+

PS: we may be clowns but years ago of testing and research !!!!!!!!!!!!!; I mounted 19 pantones (using the experience of others) before having one correct. Thanks to the "Others".

It is beautiful the zac, he will yell at me now, and how he does it when he breaks an exhaust and the car must be driven the next morning and he does not have the necessary equipment on hand, it is already good for me to have put this reactor which was available at the same time as I was rewelding my tube on the turbo flange in stride. Who can do the least the least.

but no i won't yell at you

but if you want a pantone that works there is some rule to respect (we don't know why elsewhere)

Hello Rolcopter

for a reactor to receive heat, the passage of exhaust gases must be narrow around the reactor

The exhaust gases cool at the cylinder head outlet not because C, is far from the manifold, it would be enough to isolate the pipe and the distance would have a small influence, the main reason is the relaxation of exhaust gases which makes it cools down, the purpose of the silencer is to relax the exhaust gases in a large volume with partitions

Take the example of the classic assembly that is done on small mower engines, the exhaust gas circulates around the reactor in an air gap of 2mm to 3mm depending on the conduit that we used and in addition it enters 90 on the nose of the reactor, when a 12mm rod reactor is measured in a mower engine and the same reactor on a 7 liter engine the reactor becomes hotter on the mower engine.

Su my 300TD turbo j, had placed the reactor in the nose of the turbo
and it was not heating enough, I had to install deflectors to channel the heat on the reactor.
I never managed to operate a reactor in a large conduit.
The problem is to do something that does not make too much restriction in the exhaust
the restriction should not exceed that which it has with the passage of valves, or if you do not want to make too much calculation, the exhaust hole in the cylinder head gives a good idea of ​​the surface which you must leave around the reactor, you do not is not obliged to make this restriction all along the reactor just on the party before then flaring gradually ..

Ah Zac ... mash ... then you reassure me.
This is it ... This is the first thing to say about the forum.
19 pantone before succeeding.
I am a little funny me. : Lol:
Good, well, all that motivates me to keep looking.
Like what sometimes there is not only good advice to succeed.
There are also small sentences like these that allow you to put things back in their places.
I don't know if the people who helped you did it by correspondence as we do here.
Le forum has the advantage of allowing everyone the freedom to consult it as they please, but it considerably lengthens the learning time.

Don't worry, I know the rules well enough, but there are subtleties that we do not yet understand and there are constraints such as the shape of an exhaust pipe and the place 'there is around. In this case, a right-angle bend at the turbo outlet and then it is practically straight up to the "flexible" accordion-type joint.

Hi everybody
A small round trip to Auvergne as usual, with almost the same consumption: 9,1 L / 100 one way but very busy (small move, fridge, oven, large tools etc.) and 8,1 L on the way back significantly less loaded but a little faster. I have still not changed the water injection control and on the outward journey I put too much (2 l per 100 km), poor management on my part. More interesting on site: sometimes very busy (plaster tiles full of the car 44 in all) small trips, urban trips, big accelerations to fit into the fast lanes at 110 km / h, in short everything you need to consume a maximum and only 9 L / 100 km usually without load and more gently it is 9,5 l. The more I am charged, the more I accelerate, and the less I consume! Probably more heat and also I had less water. So I really need to modify my water injection order to be below 1 L / 100 km of water.
