[Vwdiesel] Glowplug as a Monitor of engine temperature.--( works like stink )

[H . Hagar.]

There are a LOT of ways to make observations. ---- ---BUT in a diesel  ?  --Temperature is
a very important  ---TOOL.   for TUNING.

Thermistors are thermally sensitive resistors and have, according to type, a negative
(NTC), or positive (PTC) resistance/temperature coefficient.


The German Aircraft diesels that I worked on , had "Pyrometers"  at every exhaust port.
20 in all on each engine.

Electrically there are two common ways of reading temperature ----Thermistor (best)  and
Thermocouple (not so good) ---In this context the Ballast Resistor in the NEW plugs is by
far the best way of doing it.

Looks to me that Area31  --is using dissimilar metals in plugs as a thermocouple----that
will be very problematic compared to monitoring the Ballast Resistor..    For you
ewbies  --do not let my nick Hillbilly Hagar fool you ----I use my high tech as a way of
coming up with simple Cheap and practical ways of doing things.   Val Christian started
using infrared long time ago and so did I.  I even take Infrared Photographs of
things ---color. ----Pain in the butt is the thermos with Liquid Nitrogen  ---that is
required by the camera.
There are on the market --really GOOD cheap  IR   Thermometers.  ---if you have the money
?---get one --they work. Read my lips.---BUT they take a lot of practice to use.NOT
simple.

Hagar.

PS :    Today I am checking voltage   --Aluminium Head to Cast Iron block ----Ja ?
Jahwohl.   may be the best thermocouple we have ?. We shall see.
