Naturally aspirated gasoline engine three way catalytic plugging will cause the mixture to be over h

Summary. In the case of natural gas, the three-way catalytic converter will also be blocked. Whether it is burning natural gas or fuel, the three-way catalytic converter of these cars may be blocked.

Although the natural gas is relatively clean, the air filter element of the engine is relatively dirty. In the process of engine air intake, there are more impurities in it, which will also lead to the blockage of the three catalytic converters.

Hello, don't worry, I can ask for your question, but wait a minute, I need text for about 2 minutes.

In the case of the natural gas Huibu car, the three-way catalytic converter will also be blocked. Whether it is burning natural gas or fuel, the three-way catalytic converter of these cars may be blocked. Although the natural gas is said to be relatively clean and the front ear is good, the air filter element of the engine is relatively dirty.

In the process of engine air intake, there are more impurities in it, which will also lead to the blockage of the three catalytic converters.

Probably how many kilometers will be blocked.

This is not necessarily, and it is related to the environment in which the vehicle is used.

Will 200,000 kilometers be blocked.

Some run hundreds of thousands of kilometers and have to run tens of thousands of kilometers. This has something to do with the environment of the exercise, for example, there is a lot of dust or impurities in the air. This is easy to get clogged.

If the air is particularly clean in the southern region, then the possibility of this outgoing attack making the current blockage is relatively small.

Summary. Hello, Car Master Mechanic is here to serve you. Attentive, careful, attentive, for you to answer the car fault problems, for you to find the corresponding problem solutions and maintenance methods.

We will provide you with a satisfactory answer to your questions, I hope this service can help you, if it is helpful to you, I look forward to your praise and attention. I wish you a blessed Year of the Tiger and good luck. After the three-way catalytic converter is blocked, there will be no phenomenon of too thin mixture, and the obvious phenomenon after the three-way catalytic converter is blocked is that the exhaust gas is very unpleasant, and the vehicle will have a weak acceleration phenomenon.

The reason for the excessive dilute of the crown mixture is that the oxygen sensor is damaged and the electrical internal circuit is short-circuited. There is also an air flow meter, the data is inaccurate, which means that the air flow meter is damaged. Then there is a problem inside the engine, a crack just lifted, or the valve is not tightly closed.

Hope it helps.

Regular cleaning of the three-way catalytic converter not only helps to improve the performance of the vehicle engine, but also reduces the frequent alarm of the oxygen sensor of the exhaust system, which is very suitable for closed-loop EFI locomotives, and the vehicles with good driving habits can be cleaned at 10,000-20,000 kilometers.

Surface area carbon. When the car works at low temperature for a long time, the three-way catalytic converter cannot be started, and the soot emitted by the engine will adhere to the surface of the catalyst, resulting in the inability to contact with CO and HC, and in the long run, the pores of the carrier will be blocked, affecting its conversion efficiency. In addition, if the exhaust emissions are not smooth, it is difficult to exert the power of the engine, which is also the reason why many cars cannot run at high speeds.

The oxygen sensor fails.

In order to make the exhaust gas catalytic rate reach the best (more than 90), it is necessary to install an oxygen sensor in the engine exhaust pipe and realize closed-loop control, and its working principle is that the oxygen sensor will measure the concentration of oxygen in the exhaust gas, convert it into an electrical signal and send it to the ECU, so that the air-fuel ratio of the engine is controlled in a narrow, close to the ideal area (14 7:1) to ensure that the oxygen sensor works normally. If the fuel contains lead and silicon, it will cause oxygen sensor poisoning.

In addition, improper use will also cause carbon deposition of the oxygen sensor, ceramic fragmentation, heater resistance wire burning, internal circuit disconnection and other failures. The failure of the oxygen sensor will lead to inaccurate air-fuel ratio, deterioration of exhaust conditions, reduced efficiency of the catalytic converter, and a long time will reduce the service life of the catalytic converter.

The problems of shortening the service life, frequent blockage, and affecting the power of the automobile three-way catalytic converter make cleaning the three-way catalytic converter the most needed cleaning and maintenance method for vehicles. At present, the major automobile maintenance companies launched every 10,000 kilometers of "car ternary cleaning and maintenance" business is "fuel injector, air inlet maintenance" upgrade of the maintenance technology, it is specially developed for closed-loop EFI vehicles, it can clean the automobile engine air intake, combustion chamber colloidal carbon and oxygen sensor, three-way catalytic converter attached to the chemical complex. It can dredge the blockage caused by the attachment of chemical complexes to the three-way catalytic converter, restore the exhaust gas purification function of the three-way catalytic converter, and prolong the service life of the three-way catalytic converter.

It can solve the problems of increased fuel consumption, power decline and excessive exhaust gas caused by colloidal carbon deposition and chemical complexes of closed-loop EFI vehicles.

Hello <>

It is a pleasure to serve you [Flower Huai Judgment God] three-way catalytic converter is a common equipment in the exhaust gas treatment system of modern automobiles, and its main role is to convert the harmful gases emitted by the engine into harmless lead loss substances through chemical reactions. If the three-way catalytic converter is blocked, it will lead to problems such as reduced engine performance and increased fuel consumption, but it will not necessarily lead to high temperatures. Because the three-way catalytic converter also produces high temperatures under normal working conditions, the engine high temperature problem may be caused by other reasons, such as heat dissipation system failure, excessive load, etc.

Will the three-way catalyst of the natural gas vehicle be blocked: A: It will not be blocked.

1. The three-way catalytic converter converts the harmful gases discharged by the car into harmless gases.

2. The main harmful gases in automobile exhaust are carbon monoxide (CO), nitrogen oxides (NO), and hydrocarbons (HC). Three-way catalysis is the use of some chemical agents to carry out a series of chemical reactions with harmful gases in the tail gas to convert them into harmless gases.

3. If the three-way catalytic converter is broken, of course, it will lose the function of conversion, and the harmful exhaust gas will be directly discharged into the atmosphere, causing air pollution.

It is your and my responsibility to take care of the environment.

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 piece, 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 reflected, 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.
