Hello
The Mercedes has not moved, I have not yet had the time to search for an assembly and find the voltage curve of the K probe as a function of the temperature.
This morning I heard that we were presenting the (new) BMW 118D, it's quite impressive to see that they now get 143CV of a 2L turbo diesel with an average consumption of 4,7L (?) Certainly with a car significantly smaller than the Mercedes 300TD which consumed almost 2 times more with a 3L turbo of 143CV also, but 15 years ago. I don't risk getting the same results with my water doping.
But finally as they always seek to increase performance these gains in technology are partly lost, I imagine an engine and a reasonable car (power, weight) that should easily go down to less than 3L / 100 km. By cons rated reliability and especially cost of parts (injection pump, injectors, calculator, probes etc ...) it should not be the same, that said the reliability of the 300 turbo D series 124 is not a very good example.
To come back to water doping during my tests with the flowmeter I had noticed a gain (only 8%) at 120 km / h for example and none at 80 km / h, so I wonder what is really the maximum gain en route since a good part of the journey is at speed limits for operation and that the average gain can be 11 to 12% on the whole ...
To measure the consumption before trying to put back the traditional flowmeter I would like to make a test with a piezoelectric probe for the measurement of the injection time, I machined some aluminum parts to measure the deformation of the pipe which goes to a injector with probe. I feel like I'm going to spend quite a bit of time for an uncertain result !!

Hello everyone

from michelm
find the voltage curve of probe K as a function of temperature


in the absence of a curve there is a beautiful table at the end of this documentation.

Less consumption is good
Less pollution is already a great result

Hi RolCopter
Thank you ! The difference is small between 110 and 90 ° C for example, and the voltages are also very low which requires some precautions ... Everything is well explained.

Hello

For 90C = 3,682 mlv
For 110c = 4,509 mlv

When I walked with thermocouple, my repair was
4 milliviers I didn't mind the temperature,
I realized that it has a fairly large error depending on whether the junction is made under the engine hood or in the passenger compartment, at least the temperature at the junction point influences mainly to measure low temperatures.
I bought the kitchen thermometer from IKÉA it goes up to only 130c, you can easily extend the wires the margin of error is small, as I operate close to these temperatures, sometimes at the expense I then exceed below 130
recently I increased the air intake in the reactor and it gets hotter at the outlet? I have to measure the water consumption (no meter it goes bad, I will do like on the tractors walking on time,

hi Andrew
The Ikéa probe goes up to 130 ° C maximum but does it resist higher temperatures without being damaged?

Hello
Probably otherwise it would already be HS the temperature must have already risen to more than 130 ° C. The description of the thermometer indicates that the cable withstands 220 ° C if it is the same.

Michel how do you plan to use this curve (these values), for what purpose exactly?

Thank you Michelm.
Great then because the probes that I use for the fridges have trouble resisting the temperature above 130 ° C.
It's just a matter of the quality of the probe.
