Where to treat the unqualified diesel vehicle exhaust?

Diesel cars can be governed, don't trust scalpers.

There are two main fuels for cars in our country, one is gasoline and one is diesel, of which the number of gasoline vehicles is more, and now the management of automobile exhaust has become more and more stringent, so the management of automobile exhaust has also become a key to do, but because there are more gasoline vehicles, so many places will only govern gasoline vehicles, and diesel cars will be treated a lot less.

Diesel car exhaust will naturally pollute the air, this point is not much to say, for the management of diesel vehicles people should know, diesel cars can really be governed, do not believe in the outside of those scalpers or something, say that diesel cars can not be governed, can only fool these words, the management of car exhaust is definitely good for people's bodies, if you really believe in those people, then your car can not be treated you will absorb a lot of exhaust, and will also endanger the health of your family.

Diesel car owners go to those professional car exhaust repair plants to treat car exhaust, or they may be cheated, these are possible, you can go to the Internet to search for more information before the treatment, so it will be very helpful.

In the management of gasoline vehicles and diesel vehicles, Green Shield Company can be governed, and will start according to the root of the problem, which can solve the problem of automobile exhaust more conveniently and quickly, and there are many enterprises to come to Green Shield to learn the technology of diesel vehicles. Natural Green Shield will also conduct training, so that more people can solve the problem of excessive car exhaust.

People need to believe in technology, diesel cars can be managed, there is no doubt about this, so if the exhaust is not qualified, find a professional and reliable maintenance shop, which will save the owner a lot of trouble.

You can only go to the garage.

1. Clean the air filter:Clean the air filter and fuel injector. The main function of the air filter is to prevent the pollutant particles in the car from entering the internal structure of the car through the car's cold air system, thereby affecting the normal operation of the parts.

Cleaning the filter in time can effectively prevent dust from entering the car parts and components, and avoid affecting the performance of other cars.

Precautions for the use of diesel vehicles.

For the emission is qualified but the wheel power is not up to standard, the solution: you can try to adjust the fuel injection volume a little higher, and at the same time use cleaning agent to add to the fuel to reduce the smoke value of a significant increase.

If the power of the wheel reaches the standard, but the emission value does not meet the standard, this situation is relatively easy to solve, and the solution is to try adding a cleaning agent such as smoke suppression, and adding a repair agent to the lubricating oil.

Owners of diesel vehicles should also pay attention not to use some inferior gasoline, and also pay attention to whether there is damage to the three-way catalytic converter on the vehicle, so that the emission problem can be well solved.

The above content refers to People's Daily Online - there are new tricks for diesel vehicle exhaust treatment.

Treatment methods for unqualified diesel vehicle exhaust testing:

1. The emission value is qualified, and the wheel power is not enough.

Consideration should be given to whether the cylinder is injected sufficiently, as it may be due to carbon deposits that cause the injector to be partially clogged or improperly adjusted. Cleaning agents can be added to the fuel; Add a repair agent to the lubricating oil and adjust the fuel injection pump appropriately.

2. The emission value exceeds the standard and the wheel power is insufficient.

The cylinder wears and the pressure is not enough, the air intake is not enough, and the combustion deteriorates. Cleaning agents can be added to the fuel; Add a repair agent to the lubricating oil. If the power cannot fully meet the standard, you can consider installing a vehicle and ship energy-saving purification chip device in the air intake system.

3. The power of the wheel side is qualified, and the emission exceeds the standard by less than 3 times.

The air intake is not enough, the combustion deteriorates, the cylinder is slightly worn or carbon is deposited. Emission reduction agents can be added to the fuel; Add a repair agent to the lubricating oil.

4. The wheel power is qualified, and the emission exceeds the standard by more than 3 times.

Insufficient air intake, deterioration of combustion, moderate wear or carbon build-up on the injector or cylinder. Add cleaning and emission reduction agent to the fuel (if it cannot meet the standard, it can be added again); Add a repair agent to the lubricating oil. Adjust the fuel injection pump appropriately.

5. The power of the wheel side is qualified, and the emission exceeds the standard by more than 10 times.

Fuel injector or cylinder is seriously worn or carbon deposited, the adjustment of the fuel injection pump is improperly adjusted, the lubricating oil is aging, the air intake is not enough, and the combustion deteriorates. You can first use cleaning agent to clean the engine and oil circuit, and replace the lubricating oil.

Then the fuel is added with a cleaning agent; Repair agent is added to the lubricating oil. Adjust the fuel injection pump appropriately. To add emission reduction agents to fuel, it is best to install and install vehicle and ship energy-saving purification chip devices in the air intake system, and replace them if there is any damage to the components.

After May 1, 2019, diesel vehicle exhaust is generally tested for 3 items, smoke (K value), wheel power, and NOx (nitrogen oxides). Most of the exhaust gas is not up to standard due to the smoke (that is, black smoke) caused by the exceedance, and some cars are not enough power on the wheels. If the wheel power is unqualified, the wheel power must be solved first.

The power of the wheel side of the large pump truck is relatively easy to get. Adjust the throttle or fuel injection volume normally, and it can be solved, and the power will be large if you adjust it high. If you adjust the throttle, use a 10 wrench to make the throttle a little bigger, and it is recommended to go to the repair shop to find a professional master to get it.

Note: The higher the power, the greater the black smoke, and the more smoke will be. If it's not the same, just adjust it a little.

If the smoke is not up to standard, you can remove the air filter, increase the air intake, increase the combustion, and the black smoke will be slightly improved if the combustion is sufficient. Repair the second fuel injector, because some cars will be blocked to varying degrees if the fuel nozzle is not maintained for a long time, resulting in poor atomization, insufficient combustion, and increased black smoke. The oil circuit of the third school oil pump has not been cleaned for a long time, and the carbon deposition is serious, resulting in an increase in black smoke.

These can only improve the smoke to varying degrees, you can try it).

Generally, if the smoke exceeds the standard of less than 10 points, a bottle of smoke elimination No. 1 can be added.

Diesel cars are easy to exhaust substandard, repair may not be easy to repair and high cost, a grease nozzle casually more than a thousand (good cars do not know), oil pump thousands of yuan, just to take the green label suggests to find a scalper, or remove the air filter, increase the air intake, so that the fuel is fully combusted, heat up the car in advance, and a few more big throttles before crossing the line can generally pass.

Go to those Green Shield exhaust gas treatment stations approved by the Environmental Protection Bureau to change the diesel level, do some maintenance, don't be deceived by scalpers anymore, what age is it now

Repair shop repair, this method is to replace all the parts that should be replaced, and then check the exhaust gas;

To clean the tail, you must first deal with the fuel injector; If the fuel injector does not work, you need to change the three-way catalysis;

Other small methods, replacing the spark plug and flushing the exhaust pipe with water, can change the exhaust gas in a short time.

It is not difficult to get a diesel car that exceeds the standard, clean the air filter, and add a bottle of Tongjue diesel car smoke suppressant. Petrol cars are a bit more complicated.

The main emissions of diesel engines are PM (particulate matter), NOx, CO and HC. The control of diesel exhaust emissions is mainly to control the generation of particulate matter PM and NO, and reduce the direct emissions of PM and NOx.

According to the requirements of the transformation and management of the diesel vehicle market in use, the dual-drop after-treatment system (DOC+DPF+SCR) of the self-catalyzed diesel vehicle not only meets the requirements of reducing particulate matter PM in exhaust gas, but also meets the requirements of reducing nitrogen oxide NOx.

The principle of the Chinese autocatalytic double drop system: the oxidation catalytic converter (DOC), particle trap (DPF), and NOX selective catalytic reduction (SCR: selective catalytic reduction) are integrated, and the DOC + CDPF + SCR double drop post-treatment product (coated with a layer of catalyst with *** catalyst on the DPF support, that is, CDPF) is successfully developed.

On the one hand, the DOC in this product oxidizes NO2 to NO2 in the appropriate temperature range, providing sufficient amount of NO2 for the smooth passive regeneration of downstream CDPF. At the same time, it also provides NO2 for the rapid reduction reaction of SCR. On the other hand, by taking advantage of DOC's excellent fuel ignition, the active regeneration of CDPF can be successfully realized, the active regeneration efficiency of CDPF can be improved, fuel consumption can be reduced, and fuel economy can be improved.

According to the test standard of the Ministry of Ecology and Environmental Protection and the industry test standard (HJ451-2008), the conversion efficiency of the catalyst DOC to HC and CO in the autocatalytic system is greater than 80%, the capture efficiency of DPF to particulate matter is more than 90%, and the regeneration efficiency of particulate matter is more than 90%.

Installing exhaust purification devices, Wuhan Lotford Power Technology **** is a professional diesel vehicle exhaust treatment enterprise, participated in almost all the domestic "yellow label car" exhaust treatment work, is a leading enterprise in the domestic industry, you can search for it.

How do you call the exhaust exhaust car boring or....

What exhaust gases! Whether it's black smoke or green smoke.

If the car is used for a long time, the car exhaust is easy to exceed the standard, and it is easy to fail in the annual inspection. In response to this problem, there is no need to worry, the old driver said that only three methods can be done, I hope it will help everyone.

Only then does the exhaust exceed the standard, and the exhaust gas test is unqualified, either the engine is replaced, or a filter is added in front of the engine.

Take a look at this car, the machine of the big pump of China 2, the account of the open loop EFI of China 3, the test results: the power of the wheel increases, the emission exceeds the country 6b, if you want to know the secret, consult me.

Replace the spark plug and clean the fuel injector: the spark plug ignition energy is insufficient, and the mixed oil and gas can not be completely burned, resulting in the HC content in the exhaust gas exceeding the standard, and the fuel injector has a poor atomization degree, and the mixed oil and gas is too concentrated may also lead to the pollutants in the exhaust gas being too high to pass the test.

Replace high-grade gasoline: Compared with low-grade gasoline, the advantages of high-grade gasoline are mainly reflected in the "two highs and two lows": higher knock resistance and power, and lower harmful substances and exhaust pollution in gasoline.

With high-grade gasoline, it is possible to pursue higher engine power and smaller displacement, and improve power and fuel economy. High-grade gasoline is cleaner, and the content of CO, NO, and HC pollutants produced after combustion will be greatly reduced.

Clean or replace the three-way catalytic converter: the exhaust gas is discharged through the exhaust pipe, and the three-way catalytic converter on the exhaust pipe is the most important external purification device in the automobile exhaust system, which can convert the CO, HC and other harmful gases discharged from the automobile exhaust into harmless carbon dioxide, water and nitrogen. Neglecting the maintenance of the three-ring catalytic converter for a long time will lead to the blockage of the three-ring catalytic converter, the ability to convert harmful gases will be reduced, and finally the exhaust emissions will not meet the standard.

If there is a problem with the three-way catalytic converter, you can buy a special cleaning agent to clean it, and if the blockage is serious, you can choose to replace it directly.

Just add a three-way catalytic device, it's very simple.

1. The detection of general diesel vehicle exhaust will include the smoke level, that is, the K value, and the power of the wheel. If the smoke and wheel power are not up to standard, you can add cleaning agent to the fuel;

2. Add repair agent to the lubricating oil. For the emission is qualified but the wheel power is not up to standard, you can try to adjust the fuel injection volume a little higher, and at the same time use cleaning agent to add to the fuel to reduce the smoke value and greatly increase.

3. If the power of the wheel side is up to standard, but the value of the row is not up to standard, this situation is relatively easy to solve, you can try to add cleaning agents such as smoke suppression, and add repair agents in the lubricating oil. If the emission value of the diesel vehicle is seriously exceeded, it is necessary to check whether the fuel injector or cylinder is seriously worn or carbon deposited, and the parts need to be cleaned or replaced in time.
