| What
Temperature is Safe? |
In the days gone
by, these specifications would have been classified
as SAC Trade Secrets, today however, we are more
than happy to reveal this information. |
Our ongoing efforts
to constantly offer our customers the most recent
technology available in the world will never stop. |
What we want to achieve
with the new EGT gauge is that the client must be
aware of what is happening and the client must be
able to take correct action to ensure maximum mileage
from his vehicle, before any unnecessary major expenses
are incurred. |
|
|
|
No matter what the
driving condition, altitude or even ambient temperature,
the EGT should not exceed 770ºC. |
| In fact, we
are more comfortable with 720ºC for that
extra peace of mind. |
In most cases the maximum EGT will only be
reached when driving full throttle, but with
diesels that's more often than not. |
Towing
even a small load would also bring out the
maximum EGT. |
Some diesel
turbos exceed the maximum permissible EGT
while driving at a constant speed of 120 km/h. |
The biggest
problem is and will always be -
How will you know what the EGT is if there
is no gauge to show you? |
Our experience
is that with the help of the EGT gauge you
can also achieve extremely good fuel consumption
because it is directly related to the EGT. |
|
|
|
| What
if the EGT limit is periodically exceeded? |
Piston crown failure and cracking
is very common, however different makes and models use different
material for pistons and sleeves. |
Some can handle the excessive
temperature better than others. |
The first area that
will take strain is the exhaust manifold and the
turbocharger. |
Exhaust manifold
cracks and/or broken studs are a first occurrence. |
The waste gate valve area in the turbocharger starts
to melt and because one cannot see inside the turbo,
you wouldn't know. |
|
 |
|
The colouring of
the turbo is one way of establishing the inner condition. |
If the turbo is
a shade of blue, the damage is probably already
there. |
Once the waste gate has any sign
of damage, the boost pressure will change and once again one
wouldn't know because there is no boost gauge in the vehicle. |
The cylinder head in the combustion
area starts to crack, just light hair cracks at first and eventually
they crack into the water channels. |
Piston crown failure and
cracking is very common, however different makes and models
use different material for pistons and sleeves. |

Engines that continually exceed
the permissible EGT, generally don't last more than 60 000km
before they fail completely. |
Surely all this information will
make one wonder why vehicles today aren’t all fitted with
EGT gauges as standard equipment. |
Fitting an EGT gauge will not
affect your new vehicle warranty and is there to help preserve
your vehicle's engine and save money in more ways than one. |
