Turbo diesel intercooler




by baboune » 13/05/06, 11:33

can we pantonized a turbo intercooler I would like if someone and reached the pantonisé I try but I have a lot of difficulty and nothing at the level of consumption
And even more than before I would be very pleased with the help you would bring and thank you :|

Hi Baboune
Without description or any technical information it is not easy. I would say that it takes a maximum of heat (the turbo must absorb it seems to me about 100 ° C) so just reactor out of the turbo and thermal insulation. Then upstream of the reactor hot and humid air so bubbling or spraying etc. Force the engine to prime the system. Have a look at some experiments and generalities etc! Good luck for the future.

Hi baboon
I am like you no significant improvement on my space td
with intercooler
last conso 7 liters of diesel for 0,4litre of water
stainless steel reactor diameter 14 in 16 tube length 130Mm the very near the turbo outlet.with a nice stainless steel bubbler and warmed by the coolant outlet temperature = 80 ° depression in the bubbler = 200Mm to 2500Tr / m = 110Km / h
on the other hand on the link below I do not understand its assembly ??
he connected the reactor outlet directly to the intake manifold
and yet it's the same engine as mine 2.1l turbo d.

advice to specialists.

Hello Bidule
It does not serve much to measure the depression in the bubbler, if we neglect the size of the ducts it is substantially equal to the water level of the bubbler.
The depression must be measured on the pipe coming out of the reactor
according to your consumption of water it should not be well raised
Normally if your duct coming into the hose is close enough to the mouth of the turbo even advanced slightly in the cone input, it should syphoner enough, according to the noise that the bubbler has 2500 RPM it should give you a good indication,
The air inlet duct that enters the bubbler must be a big 20mm.
If you come in after the turbo and the intercooler the engine will only run at low speed when the turbo ships it pressurises and it blows into the panton
I suppose the R25 mount if it sent its output into the intake manifold so pressure side, it to do a kind of nozzle to do a dynamic suction and probably made a static air intake at the same place (collector) to feed in air the bubbler.
But if you look at the turbos tractors they did not break their head straight ahead of the turbo.
Su my momtage I place a venturi just ahead of the turbo the narrow passage of the venturi is the same diameter as the final entry in front of the turbo wheel Garrette 40mm. It is true that in my case I need a lot more depression because I work with a water carburetor.

Going ahead of the turbo is not the ideal, but it's simple and it's not because of that that your system does not work.
The figures anonncé for renault R25 on Qant Homme are realistic, these values ​​are realizable on long journeys,
driving in town thinks there is no time to warm up at each start up penalizes you too much.
Verifies that your system is waterproof
that the depression is sufficient, measured on the duct just before entering the manifold a 500mm 800mm a 2500 RPM would be desirable.
That the reactor receives enough heat (it is necessary to isolate with wool of rock, the turbo eats heat)
If the outlet tube of the reactor does not come warm, there is not enough circulation in the reactor, normally what enters the reactor is 80c what comes out easily exceeds the 100c ..

hi andre
The depression must be measured on the pipe coming out of the reactor
I send a little picture is easier.
if you see the valve on the air intake a little closed it is to limit the consumption of water (valve opened in large = 0,62litre)
valve like the picture = 0,40
otherwise I had to isolate the exhaust but I did not notice a difference either and I had to remove my insulation (a kind of girl that normally had to keep warm but now it was starting to become black so I have removed I did not want to fire under the hood (I have to find something more serious to isolate.
otherwise it's nice so it's the bike that runs so no pantone test.
andré if you exceed 30% saving on the 300 td I will open a bottle at your health

Good morning

The valve on the inlet of the bubbler is useless, I noticed that the air inlet tube in the bubbler is in pipe 1 / 2 pipe
normally it's 3 / 4, it's not that it takes so much air, a hole of 6mm is enough, but having a large immersed duct makes the bubbling bubbler work. by air cap.

Normally this does not control the consumption of steam by this method, I have not managed by strangling the entry of the bubbler,
If the bubbler is in temperature, it is the depression at the outlet of the reactor which has the most influence on the consumption of water,
The stainless steel sleeve on the turbo inlet is a simple pipe or there is a venturi in it?
I placed the venturi in front of the turbo directly insert into the rubber duct, I had a depression of 700mm of water
today i just modified this and j, made a support fit in the turbo input conne and the conduit arrives at 10mm from the central turbo nut, i did not win as much as i hoped
that pulls 820mm of water (it will be necessary that refassse a conduit flaring) I still have to redo tests.
When you approach the turbo is what is solid is well cared for it should not that it hangs the wheel that rotates at high speed, but for it to be effective it must be close.
In my case when the consumption of water is 0,5 liter is less effective than when it 0,8 liters and when it exceeds the 2 liters the engine is more clever .. C, is a 3 engine liters
You have to look for the best values ​​on your engine,
for that you need a good depression to be able to have a margin of maneuver on the consumption of water.
Driving in town and small courses the gain is low, it is only on the main road that you can make gains.

For the solation takes the rock wool the one used for electric cookers (fiber fax) it looks like glass wool but it's white of the real poison, wears a muzot mask and hurry to cover it with aluminum sticky paper.
I also notice that the insulation on the outlet tube of the reactor is not silicone normally this conduit becomes hot,
if it passes little steam lack of depression the duct is less hot, obviously there is a balance to be respected it is not necessary to pass more steam than the available heat that the reactor receives the exhaust.
In large industrial furnaces for heating steel billets, at the top of the chimney there is a motorized pappillon when it is closing the chimney is at low temperature and when it is open the chimney is at high temperature, c 'is normal it is the flow of gases that makes it heats, it is the same with the conduit output reactor,

Little heat in the outlet pipe of the reactor is
low load engine lack of exhaust heat
or too much flooded reactor water
or most often lacks circulation in the reactor
gap too tight; air intake; lack of depression.

hi andre
I noticed that the air inlet tube in the bubbler is in pipe of 1 / 2 pipe

the diameter of this tube is 16mm inner.
and I'm not sure that bigger will be better.

The stainless steel sleeve on the turbo inlet is a simple pipe or there is a venturi in it?

it's a venturi
internal diameter = diameter of the turbo angle of 30 ° and 7 ° in output ie towards turbo, I can not put it just in front of the turbo problem with the hose and the radiator.
otherwise how would you do to reduce water consumption while leaving the bubbler inlet valve open wide?


I also notice that the insulation on the outlet tube of the reactor is not silicone normally this conduit becomes hot,


it is the hose for the coolant it seems to be fine before I put copper but with the vibrations it broke anyway when I took the temperature output reactor 10cm I had about 80 ° .

Driving in town and small courses the gain is low, it is only on the main road that you can make gains.


I understand that the type of vehicle I have I will not win much because the speed is limited in France and our vehicles when have 90 roll or 110km / h are only 30% load so not asser of heat to the exhaust.
turbo diesel engine 2,1litres 2500tr / mm = 110km / h.

Hello
What comes out of the reactor is 80c.
normally what goes out of the bubbler should be at 80c so it goes into the reactor which must be at least at 400c and if that still stands out at 80c it does not go much activity in the reactor
First test ride with an empty bubbler to see if the air exchange
raises the temperature output of the reactor if it is drowning it runs on the liquid. either the bubbler is not hot enough
either it spends too much water or it condenses on leaving.

To reduce the flow of output of the reactor I retained two ways, after having tried the possible methods.
it is to put a valve at the exit of the bubbler or a restriction small led, or at the exit of the bubbler to make a small entry of air with a small valve this dilution poses a problem if one draws cold air at this level .It must be heated, to prevent this condenses before arriving at the reactor, the latter solution allows when the reactor is drowned to dry up quickly by opening the valve there is nothing but hot air that circulates in the reactor.
But the simplest way you get a connection on the line that comes out of the bubbler and you put a washer pierce with a hole of 3mm in the connection if you need to enlarge the hole. This maintains a good depression in the reactor and it calms the bubbler.
The bubbler must purr and you must clearly hear the bubbles

hi andre
my bubbler is at 80 °,
I'm going to experiment with an empty bubbler or put a second
Intermediate box to see if it condenses too much,
what should be the reactor outlet temperature when the reactor is running? 100 150 200 ° ??? this is to know what pipe to output bubbler.
