Many motorists think about tuning their vehicle, not always realizing how it can affect the operation of the purification system. The installed converter contains precious metals – platinum, palladium and rhodium – that provide chemical reactions to neutralize harmful substances. It is noteworthy that when replacing an old neutralizer, it is not necessary to send it to a landfill – Autocatalyst service offers favorable conditions for the sale of used parts.
Effect of engine modifications on the converter
Any changes in the design of the motor directly affect the efficiency of the converter. As power increases, the temperature of the exhaust gasses rises, which can damage the ceramic filler. Before replacing the converter, many owners study the current catalytic converter scrap prices list, assessing the possibility of offsetting part of the cost of a new part. It is important to remember that improper selection of system components can cause even a new converter to fail quickly.
Technical aspects of compatibility
There are several key points to consider when installing sports equipment:
- The throughput of the converter must match the planned engine output after modifications.
- The converter housing material must be able to withstand increased temperature loads during aggressive operation.
- The location of the neutralizer relative to other components requires consideration of the thermal expansion of the metal.
- The cross-section of the converter channels should be selected with a reserve to prevent back pressure.
- The quality of the fuel used directly affects the service life of the cleaning element.
Compliance with these technical requirements will significantly extend the service life of the converter and ensure its efficient operation even under increased loads. It is especially important to consider these aspects when installing a turbocharger or other serious engine modifications.
Program settings and calibration
Changing the engine’s operating modes requires adjustments to the control parameters. When tuning, it is important to control:
- Converter overheating due to improper fuel mixture composition.
- Destruction of the ceramic block by detonation.
- Clogging of converter channels when operating on a rich mixture.
- Reduction of cleaning efficiency at suboptimal operating modes.
- Premature failure of lambda probes.
Proper calibration of the electronic control unit will help to find the optimal balance between performance and preservation of the resource of the cleaning system. At the same time, it is worth remembering that even minor deviations in the settings can significantly reduce the service life of the converter.
Legal aspects of modification
Legislation strictly regulates changes in the design of the car’s cleaning system. The use of non-standard components must be confirmed by appropriate certificates. Replacing the converter with a straight-through system can lead to problems when passing technical inspection and imposing fines. At the same time, modern technologies make it possible to find a compromise between increasing power and maintaining environmental performance within acceptable limits.
