Here is what all the EGR
(Exhaust Gas Recirculation) fuss is about...
An EGR System is a simple
emissions reducing system specifically introduced to reduce NOx emission. The
EGR system allows recirculated exhaust gas back into the inlet side of the
engine. This is a continuous process and the EGR valve remains open on cruise
and all the way up to just before wide open throttle. At wide open
throttle (WOT) emissions are not tested and so manufacturers close the valve and
allow a full shot of fresh air to allow the engine to develop max power.
Mixing hot exhaust gasses with
the intake air reduces engine efficiency. The sole reason for using an
intercooler is to lower the intake air temps. This makes the air more dense, so
we get more air into the combustion chamber. The EGR works effectively to negate
the function of the intercooler.
So, the EGR will make you use
more fuel, give you less power, cause carbon build-up in the intake manifold and
ultimately reduce your engine life. But it does reduce NOx emissions, so we are
expected to accept it. Blocking the EGR system gives us two main benefits
1) Blocking the EGR will
certainly stop the soot from the exhaust clogging up the inlet
manifold.
2) When blocking the EGR port
you are redirecting the exhaust gases back out via the turbo, (where it was
meant to go).
The turbo now has more
pressure turning the blades and the turbo will spool quicker. Most people
will even be able to feel this by the “seat of their pants” dyno. ie you
will feel a marginal increase in performance and that’s a good thing.
There are many benefits
to blocking the EGR port/pipe...
-
Cooler intake air
temps.
-
More
performance.
-
Less engine oil
contamination.
-
Cleaner engine oil means
increased engine life.
-
Cooler exhaust
temps.
-
No Soot in intake which
keeps vacuum / boost lines clean
-
Increase turbo
response
-
Stop the carbon build-up in
the manifold
Compared to the negatives of
blocking the EGR System...
-
It is against the law to
change the way the vehicle’s emission control systems function. However, in
Australia there is no road side diesel testing.
-
When hot gasses from the EGR
mix with the oil ladened air, oil vapour that comes from the engine’s
crankcase, the hot air cooks the oil and causes carbon build up on the inside
of the intake manifold. In the pics below you can see the excessive
buildup of carbon.
This is what your standard air
intake manifold and plumbing will look like if you have not done any
modifications, this is not a one off, every late model diesel fitted with an EGR
are like this, an EGR plate & Oil Catch Can will prevent this allowing your
engine to run on cool, clean air.
Our EGR Blanking Plate
allows the engine to breathe oxygenated air rather than hot exhausted air.
The EGR blank is easy fit
design with slots so that you do not need to fully disassemble the EGR System …
just slot the Blanking Plate in.
Whilst we mentioned Catch
Cans for your PCV (Pressurised Crankcase Ventilation valve), here is some
related info...
Catch can not
included in this sale.
Burnt fuel contains
contaminates that used to go straight out the exhaust pipe. Now, some of these
contaminates (including soot) are being redirected back into the combustion
chamber. Engines experience varying levels of piston blow-by, where some of the
exhaust will go past the rings and into the engine sump. The more contaminates
there are in the exhaust gasses, the more contaminates end up in the engine oil.
Contaminated oil will have detrimental effects on engine oil thus reducing its
ability to protect the parts its was designed to protect.
The positive
crankcase ventilation (PCV) valve can vent a small amount of oily mist into the
intake manifold. When this oily mist comes into contact with the soot from the
exhaust gas it can form deposits on the walls of the intake manifold. Over time
these deposits get baked into a solid mass which can seriously affect air flow
through the manifold, as seen in the pictures
above.
