Is it a problem with three way catalysis or a problem with gasoline filters?

Hello, how many kilometers have you had, and can't you afford to refuel.

The three-way catalytic converter is the most important external purification device installed in the automobile exhaust system, which can convert harmful gases such as CO, HC and NOx from automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction. Because this catalytic converter can simultaneously convert the main hazardous substances in the exhaust gas into harmless substances. It is installed in the engine exhaust pipe and reacts with carbon dioxide and nitrogen through redox reactions, so it is also called ternary.

Introduction of automotive three-way catalytic converter filter elementThe main function of the three-way catalytic converter is to purify the harmful gases in the exhaust gas discharged from the car. The working principle of the three-way catalytic converter is that when the engine exhaust gas is discharged through the exhaust pipe, due to the catalytic effect of the purifying agent in the three-way catalytic converter, the harmful gases Co, HC and NOx are redox reacted at high temperature to become harmless gases, so that the exhaust gas emission of the engine is purified.

When the harmful gas passes through the three-way catalytic converter, the purifying agent will adsorb the harmful gas and carry out a chemical reaction, thus turning it into a harmless gas. It is an external purification device installed in the exhaust system, which can be used to filter harmful gases such as carbon monoxide and sulfide gas emitted by the car and convert them into harmless carbon dioxide, water and nitrogen.

The failure performance of the three-way catalytic converter is that the oil is not good, and the failure performance of the three-way catalytic converter is:

1. The first stage is the slight blockage stage. At this stage, the chemical complex is adsorbed on the surface of the catalyst. It is only manifested as a decrease in the exhaust gas purification function. Exhaust emissions exceed the standard;

2. The second stage is the moderate blockage stage: the chemical complex has accumulated eggplant dust on the surface of the catalyst to a certain extent, and the exhaust back pressure increases at this stage. Fuel consumption increases, power decreases;

3. The third stage is the stage of severe blockage. Due to severe clogging, the working temperature of the three-way catalytic converter increases. A high-temperature sintering jam is formed at the front end of the three-way catalytic converter;

4. High temperature sintering blockage. There are two types of high-temperature sintering plugging: one is metal sintering plugging.

One is carbon deposition, sintering, coking and blocking. It is determined by whether the fuel contains lead and manganese antiknock agents, and this stage is manifested as a serious decrease in power, frequent stalling, serious exhaust pipe red, and even cause spontaneous combustion of the vehicle.

Summary. That's for sure, friend. If the quality of your diesel is not good, it will lead to the blockage of this three-way catalysis, causing three-way catalysis and accelerating aging and damage.

Hello, I am helping you sort out the answer to your question, please wait a while Hello friend, if you say that your three-way catalytic damage will definitely lead to the failure of your diesel quality. Because the three-way catalysis is to catalyze these exhaust gases, if the exhaust gas is not qualified, it will cause you to inject the wrong amount of fuel. So there is a problem with this fuel injection system.

Is it really caused by the quality of diesel?

That's for sure, friend. If the quality of your diesel is not good, it will lead to the blockage of this three-way catalysis, causing three-way catalysis and accelerating aging and damage.

The purifying agent in the three-way catalytic converter will enhance the activity of CO, HC and NOx, and promote them to carry out a certain redox-reduction chemical reaction, in which CO is oxidized into colorless and non-toxic carbon dioxide gas at high temperature. HC compounds are oxidized to water (H20) and carbon dioxide at high temperatures; NOx is reduced to nitrogen and oxygen. The three harmful gases become harmless gases, so that the exhaust gas of the car can be purified.

Diesel particulate filter.

Extend the service life of the diesel engine;

Save fuel. Reduce the repair cost and maintenance time of the engine.

Diesel filter is a special diesel purification equipment for diesel for internal combustion engine, which can filter out more than 90% of mechanical impurities, gum, asphaltene, etc. in diesel, which can ensure the cleanliness of diesel fuel to the greatest extent and improve the service life of the engine. Unclean diesel will lead to abnormal wear and tear of the engine fuel injection system and cylinders, which will reduce the engine power, increase fuel consumption rapidly, and greatly reduce the service life of the generator. The use of the filter can greatly improve the filtration accuracy and efficiency of the engine using the felt filter purifier, extend the life of the imported high-quality several times, and the fuel-saving effect is obvious.

If the fuel is too low, the three-way catalyst will be damaged.

When the fuel level of some cars is too low, it cannot automatically protect the three-way catalytic converter, resulting in excessive wear.

The kinetic energy of manufacturing is not large enough to drive the catalytic converter to play.

Bad fuel is very damaging to ternary, and the low fuel level of EFI vehicles is often not good for gasoline pumps.

Hello, I haven't heard of this kind of saying, generally the gasoline is not good for the fuel pump after it is burned dry.

Some cars have too high or too low oil supply pressure, and the electronic control system is powerless against it.

Cart start is the most familiar and effective emergency starting method, but this is a means of self-help, can not be used often, because this has a certain damage to the engine and clutch, automatic transmission vehicles especially to avoid this method of starting.

The use limit of the catalytic converter cannot be reached.

It does not act on the place where the three-way catalytic converter reacts.

It will cause excessive loss of the three-way catalytic converter and affect the service life.

The three-way catalytic converter is a purification device in the exhaust system, and its function is to convert harmful gases such as CO, HC and NOx emitted from automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction. With the continuous improvement of emission standards, the requirements for three-way catalysis are also rising, although this is a problem that car companies should be concerned about, but they still encounter a variety of unexpected events in car life.

Not long ago, I was checking for a fault with weak acceleration, and the results of the inspection had to make people think deeply.

The fault phenomenon of this car (not to mention the brand) is the acceleration weakness, after inspection found that there is more carbon deposits at the throttle, inside the intake tract, fuel injector, and valve, so the throttle, intake tract and other places are cleaned, and the spark plug surface is cleaned after the test, and it is found that the situation after cleaning has improved, but the problem still exists, especially when the speed is higher. Since it has not been able to solve the problem, it is necessary to continue to check, and then the inspection focuses on the oxygen sensor, referring to the normal parameters of oxygen transmission slightly deviated, and directly reversing the processing, and then conducting a long-term test and finding that the effect is still not obvious, and the car still has obvious acceleration weakness. According to the inspection steps, almost all the items that should be inspected have been checked, except for gasoline, high-pressure oil circuit and three-way catalytic converter, which have not been checked or reversed.

The first thing to consider is the problem of gasoline, because it is more troublesome to remove the three-way catalytic, so the gasoline in the fuel tank is pumped, new gasoline is added, and the high-pressure test is carried out before the test. After the test run, it was found that the problem was not greatly improved, so the three-way catalysis could only be dismantled, and a big problem was found after the removal of the three-way catalysis - the three-way catalysis was almost blocked. The root of the problem has finally been found, the three-way catalytic converter is normally very difficult to damage, this failure is caused by poor exhaust, and the problem is solved after replacing the three-way catalytic converter (don't ask why it's not cleaning).

Through the above fault inspection, a question is revealed, why is the three-way catalysis blocked?

In fact, the answer to the question is very obvious, the ternary will not be blocked for no reason, and the key to the problem is the internal combustion of the engine. What will affect the combustion of the engine - gasoline (around a big circle, there is a bitterness), gasoline problem is a more sensitive topic, although it has also been specifically reported, in fact, the root of the problem is still in the gas station, the specific approach of many car owners believe that many car owners can also know, of course, this is just another case, we can not kill all with a stick, there are many conscience gas stations to serve us. In this can only remind the owner that he should pay more attention to the driving situation of the car, because the engine "eats oil" and does not taste good it itself is the most significant.
