CATALYTIC CONVERTER REMOVAL / DELETE

A catalytic converter is an exhaust emission control device that converts toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalyzing a redox reaction. Catalytic converters are usually used with internal combustion engines fueled by gasoline or diesel.

                                              

For compression-ignition - diesel engines the most commonly used catalytic converter is the diesel oxidation catalyst. This catalyst converts particulate matter, hydrocarbons, and carbon monoxide to carbon dioxide and water. These converters often operate at 90 percent efficiency, virtually eliminating diesel odor and helping reduce visible particulates. 

Many vehicles have a close-coupled catalytic converter located near the engine's exhaust manifold. The converter heats up quickly, due to its exposure to the very hot exhaust gases, enabling it to reduce undesirable emissions during the engine warm-up period. This is achieved by burning off the excess hydrocarbons which result from the extra-rich mixture required for a cold start.

Many factors affect the life of the catalyst, тhe most notable contaminant is lead, sulfur, manganese (used in gasoline additive), and silicon, пhosphorus, which can enter the exhaust stream if the engine has a leak that allows coolant into the combustion chamber. Zinc is another catalyst contaminant that is widely used in engine oil anti-wear additives.

The removal of a catalytic converter has two parts, emptying the ceramic and reprogramming the engine control unit (ECU). It is not recommended to electronically remove a catalytic converter without removing the ceramics.
