DURATION
As the catalyst is not actively involved in the chemical reac-
tion it provokes, its life is theoretically unlimited. However,
due to certain conditions, such as engine not perfectly tuned,
vehicle vibrations and the abrasive effect of fumes on the
support, the life of the catalyst may be shortened. Indeed, the
life of the catalytic purier is about 10000 working hours.
MAINTENANCE
The catalyst is activated by the high temperature of the
fumes which also prevents any particles from depositing on
the honeycomb; less maintenance is, consequently, needed.
We recommend cleaning the catalyst every 500 working
hours. Contact an authorised dieci service centre for cata-
lytic purier cleaning.
WATER DRIVEN PURIFIER (optional)
(g.98/C)
The water driven purifier is manufactured entirely in stain-
less steel with titanium and is resistant to high temperatures
and to corrosive sulphurous compounds which are present
in the exhaust fumes.
It consists of a horizontal cylindrical body (diameter varies
according to engine size) which makes up the water tank,
two xing brackets and a cylindrical tower located in the up-
per part of the water tank equipped with a separator.
The fumes are conveyed through an entry tube to the inte-
rior part of the purier and are passed through the water in
ne bubbles. The carbonaceous particles become heavier
upon contact with the water and fall to the bottom of the
water tank. The fumes are then directed towards the sepa-
rator which recovers the carbonaceous particles which have
not fused with the water. The white smoke emitted from the
exhaust is simply water vapour.
MAINTENANCE
Maintenance of the water driven purifier is EXTREMELY
IMPORTANT and the water must absolutely be changed
every 8 working hours. The tank must be emptied through
the spherical drain valve and clean water added through the
loading and level cock.
You can see how effective the purier is from the black slud-
ge which comes out when changing the water. The purifier
should be cleaned every 300 working hours: drain off the
water and clean the inside for a few minutes with a pressuri-
sed jet. DIECI also provides the additive TAM which, added
to the water at every change, helps to keep the purier clean.
The additive TAM also improves the performance of the puri-
er by neutralising sulphuric and sulphurous acids.
