GOLF 3 1,9D: Water doping

[PITMIX]

Thank you for the info.
In fact what I meant by pressurizing with the breather is without the use of the small air filter.
Since the oil vapor can only pass through the reactor, I think that it will be at least at the same pressure as the oil.
I found it more prudent to put an air intake to avoid the problems I encountered on the R5.

My engine already has an original oil separator. It does not manage to oil 100% of the vapors but it is already not bad.
Apparently the oil vapors do not dirty the reactor.
Well, it must be said that I have not driven since the start of my experiences on this car.
One thing is strange, I can't seem to go above 70 ° to 80 ° C at the reactor outlet (pitch measurement at the inlet of the intake).
Before I got double the same conditions.
With the steam alone I got 100 ° C, so I think my probe is good.
I plan to reinstall a column of water in place of the small air filter to see what it looks like.
This loss of temperature intrigues me.

good evening everyone

from Pitmix

My RolCopter breather can be seen clearly on the video.

Too bad for me but I'm out of video player.

from André

Still to prove the difference between free air or breather gas in the reactor if there is a significant difference?

For me two advantages
bubbling with "hot air"
remove some of the oil that settles in the exchanger

Okay i'm trying to reinstall that damn media player

Hello

On diesel it is often at 80c and 85c, I cannot guarantee the accuracy of the measurements I measure on the copper pipe close to the turbo inlet so the error mark is large the copper is cooled by the air of the engine, it is necessary that the probe has al, internal so my figures learn with reserve .. normally this tiends in the 90c 95c at 110kmh ..
What I know whatever the more or less good value what we need to know
1 if there is sufficient circulation in the reactor
2 important to know if the reactor is drowned
it is this last thing that must be detected whatever the method, the outlet temperature is not always reliable
it's just a clue,
notice when you feel that it can indeed cut the water lets air pass (little air) lets heat the reactor and sends water (little) the you will notice something, the tendency it is that at the beginning it is able to take water and we aspire, the temperature drops at the outlet, it is too late you just drowned it for a minute or more, you have to start again.
So when everything is hot, little water, and waits 10 to 15 km observes the exit temperature it rises a little and decreases again stabilizes.
The good point is when you got a certain temperature at constant speed with air, then with a little water it increases (slightly) the you have found the right water ratio, if you add one little water it goes down and you lose the pedals ..

re Goodnight

from André

add a little water it goes down and you lose the pedals ..

It is for this reason that I am reluctant when using carburetors, now I do not know to what extent the bubbler can be mastered to follow the differences in load on car engines which is more on petrol engines.

Said André since the time that you made measurements on the engines to you make a table of statement.

hi Andrew
Well, precisely the good functioning that you describe I got it at the beginning on the Golf. I was using a 130mm long rod.
I then tried without rod and thanks to my small electronic controller and the windshield washer pump I managed to obtain a similar operation but with 2 times less water and lower temperature.
Now I use a 190mm rod and impossible to raise the temperature to more than 90 ° C under full load.
Most often at 110km / h I am at 70 ° C and I measure in the tube.
On the other hand, if I use the reactor as a GV, that is to say without air circulation and with 1/4 of water in the reactor, the mud water and the reactor outlet rises to 100 ° C.
I do not know if there is poor air circulation or if the rod requires too much heat but I find it bizzare.
Before there was a huge difference in temperature without water and with water. It was double to double. 50 ° C without water 100 ° C with water and this at low speed.
On a fully loaded highway it was 80 ° C without water and 160 ° C with.
Okay I connect my water column in place of the air filter and I will keep you posted.

Hello

Said André since the time that you made measurements on the engines to you make a table of statement

I make measurements only on long journeys
Since I have been running at 100% oil, we must all measure with the small canisse so carting calibrated recipians fill full cap then measure the rest in recipiants it starts to get boring to measure like that on diesel.
the oil costs nothing it's time to go to go 100km and become another 100km measure that I miss, because I always make changes on average it is in the 7,2 liters per 100km and less '' a liter of water (when I measure)
I will try to drop as ZAC below 0,5 liters to see, because I managed to do well with 0 liters and sometimes the same with 7 liters, that's why I avoid balancing figures when I'm not absolutely certain that this is the reason, and in 1 months I will have to dedicate myself.
sometimes it's 8 liters it's rare that I manage to return to 6.4 liters as I already did at the start, I would have to think about changing the 5 injectors .. to return as before ..
it is for this reason that I do not currently give figures.

For Pitmix

Most often at 110km / h I am at 70 ° C and I measure in the tube.

What you describe is that you sent too much water at one time even if the reactor was very hot, when it receives too much water it sinks and if you continue to send it in very small quantities the temperature does not will go up more. you have to allow time to dry and the exit temperature exceeds 100c you can send a little and you wait for it to stabilize, it will increase and then go down to stay around 95 to 100c
Analyzing the temperature output of the reactor is disconcerting, to see the extremes it can take and then to become very stable.
Since the time I have been examining the steam outlet temperature I have not been able to analyze this fluctuation after a delay.

Response to André to the question asked in michelm's post:

The air hole at the inlet of the reactor is approximately 4mm. By connecting a water column in place of the small air filter upstream of the reactor, I have a depression of 30cm of water column at 4500rpm. I have 70cm right at the intake venturi, downstream of the reactor.
I have to try again with the 130mm rod that I had put at the beginning to compare the temperatures again.
I am still very surprised that the temperature does not rise higher.
I can no longer find this velocity on the temperature.
I currently have a lot of trouble differentiating with and without water at the reactor outlet temperature level. Before it was really obvious. I may have too mate the ends of the rod.
Yet I made nice cuts to compensate.
Seen on each side, the stem is like a star.



With shorter or shorter stems have you noticed any big difference in T °?
FYI, it is impossible for me to reach more than 100 ° C reactor outlet without water.
This is what makes me think that the rod creates too much pressure drop.

Hello guys.
Well!! I am the king of the Gaffe.
It's not for nothing that I changed my avatar.
I totally identify with Gaston
But yes why look for the problem from noon to 14 p.m.
The lack of heat at the outlet of my reactor did not come from the reactor but from the thermocouple probe.
What an acorn ...
From 70 ° C at full load I go to more than 140 ° C.
I finally find the functioning of my system.
I will be able to install a thermostat to cut the power to the pump and make a correct regulation.

Hello
A leakage problem at the level of my water injection syringe caused my reactor to flood suddenly.
I then immediately turned off the water pump.
By drying the excess water created steam which allowed to get a little more fishing at the level of the recovery.
The temperature of the vapor at the reactor outlet was 74 ° C.
Normally when I inject very little water the temperature is 140 ° C.

[PITMIX]

Hello
Here is the operating diagram of my reactor currently.

It is not at all scientific but simply representative of the current functioning of my system.
I installed a safety thermostat to cut the pump in case of excess water.
I operate voluntarily by intermittent and very short drowning of the reactor.
In this way I intend to reduce the quantity of water as and when.
So far I have injected a minimum of water to maintain the highest possible vapor temperature.
The I try in reverse.
This idea follows on from the involuntary experience I had due to the water leak.
I also hope to find the right dosage of water.
