Egr 3 and High pressure 3
For highly effective cleaning of the exhaust recirculation
system and the fuel system, Wynn’s have developed the EGR
The EGR3 Aerosol cleans soot deposits from the EGR system,
inlet tract and inlet valve. High pressure 3 cleans and
lubricates the wet part of the fuel system including the fuel
pump, injectors and combustion chamber.
When the temperature in the combustion chamber of an
engine is too high (over 2500 Degrees Fahrenheit), it
produces nitrogen. When nitrogen is mixed with oxygen,
nitrogen oxides, or NOx is produced. NOx mixed with other engine emissions
such as hydrocarbons, form what we know as smog.
One way to reduce these harmful emissions is to
recirculate some of the spent exhaust gases back
into the engine by way of an Exhaust Recirculation
The main component of the EGR system is a valve
that metres the exhaust gases back into the
The concept is simple. A small amount of exhaust gas is recirculated back into
the combustion chamber when the engine is prone to producing nitrogen
oxides. Since exhaust gases are inert, in the sense that they cannot be burnt
again, combustion temperatures are reduced and the production of NOx is
When the EGR system is working well, your vehicle will run efficiently and
harmful emission will be reduced.
However, if the EGR system malfunctions, too much or too little exhaust gas
will be reintroduced back into the combustion chamber. This may result in poor
running, rough idling, stalling and lack of power.
If the EGR valve sticks closed at higher engine speeds, the combustion
temperature will become too hot causing knocking or pinking; this sounds like
rattling ball bearings in a tin and is the result of fuel burning at the wrong time
(before the piston has reached the top of it's compression stroke). This kind of
detonation is very harmful to the engine. Prolonged periods of pinking will
shorten engine life or worse cause the engine failure.
If the EGR valve malfunctions at lower engine speeds, the engine may stall or
run rough at idle. Although not damaging, it may trigger the 'check engine light'
and the engine management may cut power to the engine to reduce the chance
of engine damage.
Why does the EGR system malfunction?
The major cause of EGR failure is the valve mechanism
getting stuck either open or closed. This is usually the
result of carbon deposits clogging up the EGR system.
These deposits also restrict the flow of air into the
engine, reducing engine power, increasing fuel
consumption and harmful emissions.
On modern 'direct injection' engines, the problem is increased because there is
no fuel to wash over the inlet valve to keep it clean. Carbon on the inlet valve
can also contribute to poor running.
In order to keep the EGR system in optimum condition, Wynn's have developed
EGR3 for diesel engines and DIP3 for petrol engines.
'Exhaust Gas Recirculation 3' is an aerosol developed for cleaning the air intake
system, inlet valves and
EGR valves of all diesel engines.
Provides immediate thorough cleaning and lubrication of air intake
system, inlet valves, EGR valve and connecting
tube between EGR valve and air intake manifold.
Strong power jet spray to support cleaning action.
Dissolves gum, lacquer, tar, carbon and deposits.
Easy to use, cleaning takes only 5 to 10 minutes, with a minimum
necessity to dismantle components.
Restores air flow towards the combustion chamber.
Improves engine idling.
Restores or maintains the engine performance and fuel consumption.
Eliminates and avoids starting problems.
Reduces black exhaust emissions and harmful NOx emissions
Can turn out engine emission light by restoring proper function to the EGR
For optimum results we recommend a combination of the EGR3 aerosol and a
DP3 or an HP3 liquid. As you can see in the picture below. Whilst the EGR3
cleans the EGR system and the inlet, the DP3/HP3 cleans and lubricates the
'wet' part of the fuel system.
