Catalytic Converter

THE ADVANTAGES IN CHOOSING MTS
PIPES AND BOXES DIMENSIONS AS THE ORIGINAL EQUIPMENT PRODUCT
• Perfect fit-ability
COMPETITORS: changed dimensions to semplify the production
PIPES IN AISI409 WITH 1.5 MM
THICKNESS

• higher mechanical strenght
• greater protection against rust
• Avoids the detachment of metallic
particles, which would ruin the
monolith
COMPETITORS: aluminized with
1,2 mm thickness; risk of detaching
particles, which ruin the monolith
PIPES: BENT WITH INTERNAL BALL
AND NOT PRESSED

• regular bend diameter
• optimal back-pressure
• more engine power
• less fuel consumption
• less over-heating risk of the engine
COMPETITORS: pipes bent without
internal ball or pressed
FLEXIBLE
• Interlock as the original for a longer
life
COMPETITORS: simplified liner to
reduce the production costs
 
EXTERNAL WELDING WITH
GUARANTEED RESISTANCE

• robot welding of all the fl anges
ensures their perfect resistance
COMPETITORS: manual weldings with
risk of loss pressure and leaks
BOXES IN AISI409 WITH 1,2 MM
THICKNESS

• high resistance against vibrations and
hurts
• avoids the detachment of metal
particles that ruin the monolith
• high resistance against rust
COMPETITORS: 1,0 mm stainless steel
thickness with reduced resistance
CINTERNAL WITH SAME
CHARACTERISTICS OF THE ORIGINAL
EQUIPMENT PRODUCT

• same elements
• same dimension
• same volume
• same number of cells
COMPETITORS: semplified internal to
reduce the production costs, but with
less performance and shorter lifetime
 
CERAMIC MONOLITH WITH SAME
CHARACTERISTICS OF THE ORIGINAL
EQUIPMENT PRODUCT

• low back-pressure
• quick heating
• constant working temperature
• same surface covered by noble metals
COMPETITORS: metal internal with
lower performances
CERAMIC PAD PROTECTION
• isolates the monolith from the metal
housing
• compensates thermal expansions
• protects the monolith from excessive
vibrations
COMPETITORS: lower elastic
protections with brake-risk of the
monolith
AVAILABILITY OF MONTAGE KIT
• complete kit as Original
COMPETITORS: no kit or partial
kit, which miss some essential
components
CERTIFICATES AVAILABILITY
• Certificate of Homologation
• Certificate of Guarantee
COMPETITORS: absensce of certificates
that are very useful to the f nal
customer
CATALYTIC CONVERTERS

What it is and how it works
The European Community, which is becoming more careful to respect the environment and to limit the toxic issues, obliges the producers of car to furnish them with catalytic converters. The catalytic converter is a monolith, produced similar to a bees’ honeycomb structure in order to create a big surface, which is covered by precious metals (such as Platinum, Palladium and Rhodium).
The vehicle exhaust gases, which are of a very high temperature, come in touch with the precious metals within the unit, and they are subjected to a chemical reaction which oxidizes and reduces the poisonous gases making them less noxious.

Before the replacement:
It is necessary to solve any possible malfunction of the vehicle:
1 wrong electronic regulation or wrong balance between air / fuel
2 delayed or advanced ignition in the engine, faulty lambda sensor, faulty injectors, defective valves which can let unburned fuel reach the catalyst, inflames itself an burn out the catalytic converter.
3 time-worn engine components which let oil or antifreeze liquid reach the catalytic converter, creating ashes which increase the back-pressure and reduce the engine power and its life.
4 damaged spark plugs and cables, which can let unburned fuel reach the catalyst, inflames itself an burn out the catalytic converter.
5 damaged oxygen sensor, that send the wrong data to the electronic control unit, with the consequent creation of a wrong mixture of air / fuel, weather too rich, which would burn out the monolith or too poor that wouldn’t spark the chemical reaction, necessary to the oxidation of noxious gases.
6 anomalous vibrations, caused by damaged hangers, or received shocks which destroy the monolith, that is made of very thin and delicate ceramics. The broken ceramics interrupts the gas flow, increasing the back-pressure or comes out from the catalytic converter leaving it empty.

During the replacement:
1 always use new rubber.
2 put the catalytic converter perfectly in line, to avoid vibrations or abnormal pressures.
3 do not to use metal hammers or other hard tools which could break the monolith
4 as sealant use silicone and not the normal paste for the exhaust system
5 carefully verify the new emissions, to solve immediately eventual problems.

Guarantee:
Are not covered by guarantee all the damages caused by external factors as:
1 monolith braking caused by anomalous vibrations or impacts due to accidents or uneven road surfaces.
2 monoliths burning out, caused by a bad regulation of the engine
3 obstruction of the monolith caused by the use of paste instead of using the correct sealant silicone
4 obstruction of the monolith caused by wrong fuel
5 obstruction of the monolith caused by oil or antifreeze liquid contamination
