The three-way catalytic converter can convert the main harmful substances in the exhaust gas into harmless substances, but due to the high sulfur content and poor oil quality in the fuel, the three-way catalytic converter will be attached to a large number of chemical complexes for a period of time, which will then block the three-way catalytic converter, and then it is necessary to clean the three-way catalytic converter.
First check whether the car engine is faulty, check whether there will be air leakage, and check whether the engine's air intake, ignition, and fuel supply system meet the requirements, if there is a fault, it should be repaired first, and then cleaned after elimination, if there are cracks or combustion lumps, etc. do not clean, it is recommended to replace it directly. If the fault light flashes due to occasional inferior fuel added, it will generally display the oxygen sensor failure, and in most cases it will occasionally fail, just clear the fault code.
Before cleaning the three-way catalysis, the fuel injection nozzle, air intake, and carbon deposition in the combustion chamber should be cleaned according to the situation, and the effect is better.
Our products can solve the problem of exhaust gas not up to standard, achieve the role of environmental protection of automobile travel, stable performance, reliable quality, durable, professional and technical personnel design and production, factory inspection quality assurance, easy installation and save manpower.
The first thing to say is: the carbon deposition produced by the engine is a normal phenomenon, and all cars have it. This is unavoidable, especially for direct injection engines. So some degree of carbon deposition yes.
It is mainly due to insufficient combustion of fuel in the place where the engine is generated, or the stones, gas accumulation, fuel injection, and spark plugs that cannot be completely burned in the fuel nozzle, and then act at high temperatures. carbon deposits.
If the carbon deposition lasts for a long time, it is easy to cause the normal operation of the engine components. The common phenomena are starting failure, unstable speed, power drop, or the phenomenon that the vehicle cannot be accelerated to work normally.
It is in daily travel that there are many situations that will lead to the formation of low carbon, idling, accumulating heat, and uninterrupted driving for a long time, resulting in insufficient fuel combustion in the vehicle, resulting in the formation of carbon on a global scale.
