EGT – Exhaust gas temperature Monitoring

[Gertc]

I like my KZTE in a running condition and sins this is my first diesel vehicle my knowledge is about ZERO on diesels. I heard about this EGT monitor system but had no idée what it is and what you use it for.

Well sins Saturday I have found out that you can cook you diesel if you are running it too hard for to long or if you are towing the wrong way. So this EGT is a pre warning system that warns you that you engine are been over worked.

I also found out that it is a temperature probe that is being installed in the exhaust manifold just before the turbo. That measures temperatures between 650 and 850 degrees Celsius. As 850 is close to cooking the engine.

I got some prices on the EGT Monitors of between R2200 and R3500.

Can anyone advise me if is money wel spend or is it only a sales gimmick.

Please let me know if I got the wrong facts.

Hi Gert,

All the guys running Turbo Diesels speak highly of the EGT modification. Some guys have actually built their own EGT conversions using Aircraft gauges. Your theory as you explained it is correct - heat destroys Diesel engines, although the KZTE is fairly reliable as is.

You could also speak to (forgot his name - Piet? Nic?) at JY Motors in Orkney, on the main FS road just across the second turn-off to Orkney. He does various conversions for Petrol engines, not sure about Diesel, but give him a buzz.

I`m also planning on building my own. I’m just waiting for some prizes on the thermal couple K-Type temp. probe. and a 12volt Indicator.

Like you, after learning about how "easy" it is to cook a diesel engine, I also decided to fit one.
Just didnt get round to it yet.

Seems the best one to buy is the MGL Avionics one. About R3500.

Will you please do an article on building your EGT Monitor and post it for us?

Gert lyk my die Diesel gogga het jou gebyt ou maat :o Ek hoop jy kan daai meter bou vir goedkoop want om so baie geld te spandeer om temperatuur dop te hou is nie vir my logies nie, want as jy nou sien die perd hardloop warm wat gaan en kan jy dan doen om dit koeller te kry Ek dink jy moet ligter op die voet wees dan hardloop alles gewoonlik koeller :D

[Gertc]

Ja wel dit is al wat jy kan doen om hom koeler teloop is om jou voet bietjie op tetel. Maar hy behoort jou darm `n goeie idee tegee wanneer om dit tedoen.

Eben, die monitor waarsku jou as die enjin begin warm loop. Hy moet so gestel wees dat hy jou vroegtydig laat weet. Sodoende kan jy stadiger ry om skade te voorkom. As die hoe temperature dan aanhoudend is, weet jy jy het n probleem, en kan jy laat kyk en regmaak voor jy groot skade op die enjin kry.

Ek sleep redelik gereeld swaar vragte. Het nog nie n EGT monitor op nie, maar voel al is R3000 baie geld, dit my moontlik n klomp geld kan spaar sou iets verkeerd gaan.

Gert, I forgot about this. Saw it today in my inbox. If do not build the monitor yourself, check out this site:
http://www.turbologix.co.za

Thys quote me R1500 last year some time.

This monitor has a turbo protector, which will idle the engine to reach a preset temp before switching off, as well as
diesel pump cut off, which will shut down the diesel pump should the alarm be ignored on the preset temp settings.



Just waiting for Thys to get to work again and I'm gonna fit it.

[Knersus]

Ja klink baie prakties maar sal die temperatuur naald van die bakkie nie begin klim sodra die enjin begin warm word nie of waarsky die meter jou voor die bakkie se naald jou sal waarsku. Kyk ek ken nie die goed nie maar my klien koppie se vir my hitte ontstaan mos in die cylinder head se "combustion chamber" wat die afrikaans ookal is, so as die meter die uitlaat gas se temperatuur meet en dit begin styg dan moet die water temp mos ook klim. Kyk ek kan mos nou baie ver verkeerd wees maar my logika se vir my hitte is hitte :|

Miskien kan ek bietjie meer uitvind oor die ding

The TC1 gauge is a single Probe gauge that are being used in aircrafts to measure the EGT.

http://www.mglavionics.co.za/

I phoned MGL AVIONICS (011 455 4203) and got a price on the TC1 and TC2 gauges and a probe.

TC1 = R 850 Vat inc.
TC2 = R 1166 vat inc.
Probe = R 226 vat inc.

So far the best price jet

Gert, dis goeie pryse.
Ek kan nie onthou nie, maar iewers het ek iets gelees of gehoor van MGL se EGT monitors wat R3000 is.
Dalk verwar ek dit met iets anders.

Lyk my MGL Avionics is die beste EGT monitor wat jy kan insit.
In daai geval gan ek hom sterk oorweeg.

Wat is die verskil tussen TC1 en TC2?

[Gertc]

Wat is die verskil tussen TC1 en TC2?

omtrend R316 !

Nee ek weet nie ek het hul prys gevra op die TC 2. Die verkoopsman het toe net gese dat die tC2 het glo nog `n probe op wat nie op `n voertuig gebuik word nie. So kan ek met TC1 oor die weg kom.

So die R316 betaal bus vir die probe en jy kry nog kleingeld.

Manne die goed word duidelik in vliegtuie gebuik :roll: Julle ry Hi lux's en dit het nie vlerke nie

Hi Guys

I think this is the same equipment..

http://www.madman.co.za

If I am getting the posting of the URL wrong, I do appoligies. I only joined here this morning and still not sure how the buttons work here.

[ToyX4]

Thanks David

Got prices for them as well, October last year
EMS1 = R 1450 + vat
EMS2 = R 1100 + vat
Probe = R 160 + vat

I'm leaning towards the Turbologix unit, has it has the turbo protector feature. Sometimes it's a hassle to sit and wait for the one or 2 minutes to idle the engine.

[Bfreesani]

Can you by-pass the turbo protector in case you are prepared or need to switch off in a hurry/emergency.

The madman setup will do a cutout if rollover is detected. Wonder which system would win if it figures the turbo is too hot and wants to keep the engine running to cool it down :roll: ... just wondering..

I suppose each system has it's merits. I like the comprehensive display but even the facility to scroll through all the sensors still does not give me the constant monitoring of everything at a glance. unless I get a display unit for every sensor I install..

You can't have everything I suppose, well not on our budgets anyway.

correct me if I'm wrong, but isn't the whole idea of a turboprotector to be able to switch off the vehicle, lock up and go where ever it is you're going, while the engine shuts off by itself? :) Why would you want to by pass it?

Don't know

Yip, we can't have everything we want :)

Is dit nie onwettig om 'n enjin te laat loop van 'n voertuig sonder dat daar iemand is wat aanspreeklik is vir die voertuig nie.

Good point about the emergency cut out for the engine. Say there is a fire under the hood and you need to switch off the engine to stop the fire Interesting point :?

Goeie punt. Ek aanvaar dis onwettig, en ek los altyd my voertuig in 1ste rat so ek gaan dit seker nie gebruik nie.
Sal soms gemaklik wees hier op die plaas, waar dit nie onwettig is nie

Ek kan nie onthou nie, maar iewers het ek iets gelees of gehoor van MGL se EGT monitors wat R3000 is.
Dalk verwar ek dit met iets anders.

Ek onthou nou, dit is omtrent wat SAC vra om n EGT in te sit! Maar dis nie n MGL eenheid nie.

[SuidWes]

Ja dit is onwettig. Ons het verlede jaar probleme opgetel by Onseepkans toe ons die bakkie aan gelos het aan die SA kant - daai manne kan darem vinnig moeilik raak......

We seem to be going off the point slightly... This thread started off discussing EGT Monitoring and we have ended up on the Turbo Saving.

I put my 2 cents in on another active thread yesterday regarding the Turbo. Running the engine is not going to drop the EGT, OK well it dose, but it is just about instantaneous according to the EGT meter which is measuring the combustion temperature. The temp drops as soon as the fuel is removed from the equation.
