Factory Direct High Quality Engine Parts Exhaust Manifold Catalytic Converter

Product Description

What`s Catalytic Converter
A catalytic converter is a device that uses a catalyst to convert three harmful compounds in car exhaust into harmless compounds.The three harmful compounds are: 

-Hydrocarbons VOCs (in the form of unburned gasoline, produce smog)
-Carbon monoxide CO (is a poison for any air-breathing anima)
- Nitrogen oxides NOx (lead to smog and acid rain)

How does catalytic converter work
In a catalytic converter, the catalyst (in the form of platinum and palladium) is coated onto a ceramic honeycomb that are housed in a muffler-like package attached to the exhaust pipe. The catalyst helps to convert carbon monoxide into carbon dioxide(CO to CO2 ). It converts the hydrocarbons into carbon dioxide(CO2 ) and water. It also converts the nitrogen oxides back into nitrogen and oxygen.

Warranty Information of Aftermarket Catalytic converter:

  Our catalytic converter is warranted for 1 year or 30,000 kilometers, whichever comes first. At the conclusion of the 1 year or 30,000 kilometers period, whichever is applicable, all liability under this limited warranty shall terminate.
  Although every effort is made to ensure our catalytic converters will not fail, sometimes a problem with the vehicle will cause them to break down. The following problems are NOT covered under our warranty: 

Road Damage 
  This is external damage caused to the catalytic converter by hitting solid objects in the road. i.e., speed bumps, large rocks etc.
Plugged Or Contaminated.
  Plugged or contaminated catalytic converters are caused by using the wrong sort of fuel in your car. Using leaded or lead replacement fuel will plug up the monolith and cause it to stop working. A similar thing will happen if fuel additives are used that are not suitable for use with a catalytic converter.

Oil Fouled
This is caused by oil getting into the exhaust system and contaminating the catalytic converter. The most likely cause is a leaking gasket.

Melted/Broken Substrate 
  A monolith is usually broken when it is impacted by an object or when it suffers a sudden change in temperature. If the cat suffers road damage (See section on "Road Damage") the monolith inside can be cracked due to it being crushed by the movement of the steel can.
  The use of exhaust paste before the cat can also cause the monolith to break. When the exhaust paste has hardened small pellets can break away and shoot into the cat. The monolith will gradually be destroyed by these pellets and break down. The cat can also be destroyed by excessive engine vibration.
  A rapid change of temperature can also break the monolith. (See number 7 in "Caring for your Catalytic Converter") 
  The monolith can be melted when unburned fuel is injected into the cat. This can be caused by the car being tow or bump started, or if the car's engine requires several turns before firing. More information on the causes of melting monoliths can be found in the section on "Overheating".

Overheating
  There are many problems that can cause a cat to overheat or fail. The most common cause is unburned fuel entering the cat. Also faulty spark plugs and leads will cause the engine to misfire and ruin the converter. The cat will also be ruined if the distributor timing is out.

Oxygen Sensor
  An oxygen sensor collects and sends information to the Electronic Control Unit. This is used to control the air/fuel mix . If the oxygen sensor is faulty, or it has been contaminated with silicone from anti-freeze or sealant, the air/fuel mixture will not be corrected and excess fuel will enter the cat, causing it to overheat. 

Fuel Injection Systems 
  If a fuel injector is leaking internally or dribbling fuel into the engine the converter may be damaged. The excess fuel will enter the exhaust system and cause the cat to overheat. Due to the varying fuel injector systems the proper manual should always be consulted when trying to diagnose a problem.

Map Sensors
  Map Sensors tell the Electronic Control Unit the load on the engine and the amount of air entering it. If this sensor fails it causes a rich condition in the engine which can overheat the cat and cause it to fail.

Carburettor Systems
  A worn or defective carburettor can cause a cat to overheat. Problems such as improper float or air/fuel mix adjustments and worn metering rods can damage the cat. The choke system also needs to be operating properly so the right level of fuel enters the system. If too much fuel enters the system the cat will overheat and eventually fail.

Canister Purge Valve Control
  This vacuum operated valve vents fuel vapour from the carburettor bowl to the charcoal canister. If the vacuum is breached the charcoal canister will flood, causing the air/fuel mixture to become very rich. This will cause the converter to overheat and eventually fail.

Noise
  A cat should not be considered to be a silencer although it does have some silencing qualities. Noise can be caused by excessive fuel getting into the converter
