EGT Installed

Post by Pieter du Toit »

Hi All,

At long last - my EGT is installed - and a million thanks to Mr Tour de Frans - he has done one excellent fantastic & neat job - well done Frans and thanks again!! :thumbup: All I can say it is no joke to get it done on the 3.0l diesel - no wonder nobody gets back to me with a quote. I will post a photo later of Frans's installation.

A question which neither me nor Frans had the answer to - I (he) installed the Madman EMS system - and in the setup menu of the monitor you must select whether you are using a K-type or J-type probe - does anybody no how you distinguish between these 2 types of probes?? Or whether it even does make a difference in the egt readings that you would get?? :think:

Unfortunately they don't give an explanation of the two types in the instruction manual. Any wise men out there?? :oldtimer:

Hi Pieter
To answer your question we need to first identify what you are talking about.

The Madman EGT system uses a thermocouple as temperature probe.
What is a thermocouple? A thermocouple is a temperature sensor that measures temperature by generating a small voltage signal proportional to the temperature difference between the junctions of two dissimilar metals. One junction (the hot junction) is typically encased in a sensor probe at the point of measurement; the other junction (the cold junction) is connected to the measuring instrument. The measurement instrument measures the voltage signal and the cold junction temperature then computes the temperature. (http://www.heatonc.com)

Your question regarding the type of probe refers to its sensitivity.
Type K
Chromel ( Nickel-Chromium Alloy ) / Alumel ( Nickel-Aluminium Alloy )
This is the most commomly used "general purpose" thermocouples. They are available in the ~ -200 °C to +1200 °C range. The characteristic of the thermocouple undergoes a step change when a magnetic material reaches its Curie point. This occurs for this thermocouple at ~ 352°C. Sensitivity is ~ 41 µV/°C.

Type J
Iron / Constantan
Limited range (~ -40 to +750 °C) makes type J less popular than type K. The main application is with old equipment that cannot accept modern thermocouples. J types cannot be used above 760 °C as an abrupt magnetic transformation causes permanent decalibration. The magnetic properties also prevent use in some applications. Type J's have a sensitivity of ~ 53µV/°C.

So, Yes, which setting you select will have an impact, particularly as the type J has a max reading capability of 750°C. If your engine works really hard, this reading can be exceeded and as stated will cause permanent damage to the probe. Make sure you have fitted a type K and that the EMS is set to read type K ranges.

Hope this helps

Hi Saltman,

To be quite honest you are speaking greek to me?? :helpsign: What I do make sense of (if interpreting correctly) - is that the J-types seems to be the "older type" used.

In the manual (although they do not distinguish between the 2) they do say that the probe supplied with the Madman EMS can handle temperatures of up to 1400 degrees - I would therefore think that it will be a K -type probe. Also when the meter was powered on the the setting it was on in the EGT setup menu was K-type - and I did leave it at that.

I just wanted to be sure that I am using the correct setting - and I think you gave a very thorough explanation of it - although most of it completely greek to me :redface:

Thanks anycase for your time in giving it - it does help even Blondies like me understand things better :clap:

Regards

Sorry Pieter

Hier is die Afrikanse weergawe:
As die sensor wat jy ingesit het tot by 1400 grade celsius kan lees, dan is dit 'n tipe K en as jy die brein gelos het op die tipe K insette, dan sal jy die sein reg lees en interpreteer, so jy sal die regte temperatuur lesing kry op jou instrument !

Overset synde = moenie worry nie, joune sal reg werk!

Wat jy nou moet weet (en hier is hopelik genoeg dieselkoppe op die forum om te kan help) is die volgende:
1. Wat behoort die gemiddelde temp te wees as jy gewoonweg ry.
2. Wat is die maksimum temp wat jy kan handhaaf oor 'n langerige rit as die enjin hard werk (bergpas, swaar gelaai, sleep 'n wa ens)
3. Wat is die maksimum temperatuur wat jy slegs op kort afstand kan / mag bereik voor skade intree

Hoop dit help meer ...

Saltman,

Nou praat jy mos my taal man - ek het aan jou naam afgelei jy is n "soutie" so askuus daarvoor!!

Dankie - ek het nou nogal gewonder ook oor daardie vrae wat jy daar stel - so waar is nou die diesel experts - wat se julle manne??

Net een vragie - die bietjie wat ek nou al gery het - daai egt meter hardloop rond erger as n rev counter - ek sal nou op die n1 ry en op 450 grade sit - afklim op n off ramp en teen die tyd dat ek by die robot stilstaan het die egt teruggesak na se maar 250 grade. En met die wegtrek slag dan klim dit sommer weer onmiddelik - so wat ek probeer se is daar is nie regtig n konstante egt lesing nie tensy ek op n gelykstuk pad is en my spoed handhaaf.

Ok diesel experts - kom gooi my toe met julle kennis asb!!!

Hallo Pieter,groot plesier om aan jou kar te werk.Die egt's sal op en af gaan soos wat jou regter voet beweeg.Ry jy platvoet (nou gaan ek my taal meng) fuel die ecu die enjin en die turbo spoel,nou is daar boost en die ecu sien boost en pas die fuel aan om die beste veilige kraglewering te kry.Al bly jy platvoet het die boost en fuel gesettle,sal die egt ook konstand bly volgens die uitlaat gas wat een hitte is op daardie stadium.Sodra jy jou voet af haal verminder die ecu die fuel,dmv n tps(throttle position sensor)sien die ecu wat jy met jou voet maak.Die boost val ook weg want daar is nie meer fuel om die turbo te spoel nie.(daai is meganies)Die turbo het ook n waste gate wat die boost beheer wat ook meganies is.So jy trek weg by n stop bv en die ecu sien die tps se waarde verander(meer)en fuel die enjin om hom aan die gang te sit,die turbo spin maar spoel nog nie.die waste gate is ook toe op niks of lae boost,sodat hy maklik kan opspin(boost).Nou sal jy sien die egt's is bv 400 grade maar jy ry nog nie eintlik nie.Dis die ecu wat die enjin fuel om hom aan die gang te kry sodat die turbo wat meganies is kan boost,en sodra hy boost kom die egt's af,want daar is nou onmiddelik meer lug maar nog dieselfde fuel,as jou voet op een plek was se maar kwart throttle net om weg te trek en konstant te ry.Nou boost die kar en die fuel settle asook die egt's.Die turbo se wastegate sal oop maak op n bepaalde boost so dat die boost nie weg hardloop nie of overboost.Hoe meer throttle hoe hoer die egt's en hoe minder throttle hoe minder die egt's.Hoe meer konstand jou spoed en throttle so sal die egt's ook maak.Hoop dit help Pieter.
Groete Frans
O ja miskien moet ons n dyno dag maak,dan kan julle so ook kragte meet en jul karre stilstaande in volle aksie sien.net n idee,ek kan dit reel.(hier in die Kaap) :thumbup:

Hi Pieter, eks nie n fundi op die enjin nie, maar my kennis strek soos volg.

Post Turbo temp. is gemiddeld 150-180 grade laer as pre turbo, dws 550 grade is die upper limit wat jy nie moet oorskry nie.Bo 720 grade pre turbo , begin die eienskappe van metaal verander, en dab BANG!!!!!!

Op myne , as ek sleep gelyk pad teen 110 km/u hardloop sy gemiddeld 380-450 g/c,(buite dan so 30g/c plus) enige klein opdraand klim dit soos n ref counter. Wat ek dan doen sit terug 4de toe, en lig my voet n bietjie en hou dit onder 500 g/c.Maar O WEE , as jy kyk is mens partykeer klaar oor die 550 merk.
Ek sal ook na n lang opdraand en swaar trek die Troll laat coast, maw hardloop teen kompressie, dit koel die Turbo die vinnigste af.

As jy spoed beheer het, sit dit af wanneer jy sleep, dit is die grootste killer van n diesel onder stress, wanneer mens moet minder brandstof moet gee, word dit deur die spoedbeheer overfuel en dan sal jy temp. kry van ver bo 700 g/c .

Ek skakel ook nie enjin af bo 200 -220 g/c nie, sal dit luier tot ek dit bereik.

Wat jy sal agterkom, hoe verkeerd het jy n diesel enjin gery in die verlede, en hoe baie warm ambient temp. n diesel beinvloed(n diesel enjin hou nie van n warm somer Afrika dag nie)
