Nissan Qashqai three way catalytic conversion system cylinder set 1

The three-way catalysis needs to be cleaned.

Three-way catalytic lack of town device.

The three-way catalytic converter is on the exhaust manifold, which is the head section of the exhaust pipe.

The three-way catalytic converter is installed in the exhaust system of the car and is the most important external purification device.

This kind of travel intellector can simultaneously remove car exhaust.

The main hazardous substances in are converted into harmless substances. With the increasingly stringent requirements of environmental protection, more and more Fushu vehicles are equipped with exhaust gas catalytic converters and oxygen sensor devices, which can convert harmful gases such as CO, HC and NOx emitted from automobile exhaust into harmless carbon dioxide through oxidation and reduction.

Water and nitrogen. Because this catalytic converter can convert various major harmful substances in the exhaust gas into harmless substances at the same time, it is called ternary.

Summary. Qashqai's three-way catalytic converter is a device used to reduce three harmful gases (carbon monoxide, nitrogen oxides, hydrocarbons) in automobile exhaust gases. If the three-way catalytic converter is broken, resulting in high emissions, then it needs to be replaced.

However, if it is not clear which specific part of the problem is wrong, it is necessary to use professional testing equipment to check and find out the problem. In general, if the catalyst layer is aged or damaged, then the entire catalytic converter assembly needs to be replaced. If it is a other problem such as an air leak, the corresponding parts need to be replaced.

In short, which section to replace depends on the actual situation, and it is recommended to go to a regular car after-sales repair shop for inspection and replacement.

However, if it is not clear which specific part has the problem, the crack needs to be checked with professional loss detection equipment to find out the problem.

In general, if the catalyst layer is aged or damaged, then the entire catalytic converter assembly needs to be replaced. If it is an air leak and other problems with its pin width, you need to replace the corresponding parts.

You've done a great job! Can you elaborate on that?

The temperature of the exhaust gas and exhaust system is high. People, animals, and flammable materials should be kept away from exhaust system components.

Do not park your vehicle on flammable materials such as hay, waste paper, or rags. Failure to do so may ignite and start a fire.

A three-way catalytic converter is an emission control device installed in an exhaust system. The exhaust gases are burned at high temperatures in a three-way catalytic converter to help reduce pollutants.

It should be noted that:

Do not use leaded gasoline. The sediment produced by leaded gasoline can severely impair the ability of the catalytic converter to reduce exhaust pollutants and/or damage the catalytic converter.

Please keep the engine working properly. Ignition failures, fuel injection failures, or electrical system failures can cause too much fuel to flow into the catalytic converter, causing the catalytic converter to overheat. Do not continue driving if the engine lacks fire or if significant loss of performance or other abnormal operation is detected.

Please go to the Dongfeng Nissan franchise store immediately to inspect the vehicle.

Driving with the fuel level too low should be avoided. Running out of fuel can cause the engine to lack fire, which can lead to damage to the three-way catalytic converter.

Do not allow the engine to idle during warm-up.

Do not use leaded gasoline. Using leaded gasoline can damage the three-way catalytic converter.

MR20DD engine type shed:

Please use unleaded regular gasoline that meets the Beijing V standard (at least No. 92) or the Bisock country III or IV standard (at least No. 93).

HRA2DDT hair chain number scatter motif model:

Please use unleaded regular gasoline or ethanol gasoline (not exceeding E10*) that meets the Beijing V standard (at least No. 92) or China III or IV standard (at least No. 93).

Ethanol gasoline is a mixture of ethanol and gasoline. For example, "E10" is a mixture of about 10% fuel ethanol and 90% unleaded gasoline.
