What is the reason for the high consumption of urea in diesel vehicles?

The reason for the high urea consumption: the vehicle is weak, and the urea consumption is normal. Fault phenomenon: the owner reacts that the vehicle is weak, and the urea consumption is normal. If you refuel urgently, you can find a small amount of white smoke from the silencer. Fault analysis: Use the diagnostic instrument to read the fault code that the engine emission exceeds the standard, and there are no other faults.

The reason for the road conditions is that if you walk on the undulating section of the mountain road for a long time, it will cause insufficient combustion in the vehicle engine. The quality of the exhaust gas can be imagined, which is also the reason for the large consumption of urea.

It may be the use of poor quality car urea. Generally, good quality car urea is basically 3%-5% of the fuel consumption. Therefore, the rapid consumption of car urea is likely to be that the quality of car urea is not up to standard and the purity is insufficient. It's because of the size of the car's displacement.

What will happen if the national fifth engine does not burn urea?

Damage to the SCR injection system: If there is no urea for a long time, the nozzle, pipeline and urea pump in the SCR system may be crystallized and blocked, or damaged by high temperature.

If the national fifth truck does not burn urea, it will pollute the environment, weaken the power, and damage the SCR injection system. You should immediately go to a professional 4S store for testing and maintenance. The specific reasons may be: urea pump damage, urea pipe blockage, nozzle blockage, etc.

Polluting the environment, in order to take into account the particle emission performance, the national fifth SCR vehicle is marked in advance. If urea is not sprayed, the nitrogen oxide emission is more serious than that of the national third vehicle.If there is no urea cycle for a long time, nozzles, pipes and urea pumps are prone to crystallization and blockage or high temperature damage, and car repair is very expensive.

Guowu diesel vehicles that do not burn urea for a long time are easy to cause blockage of the exhaust pipe, reduce the torque of the engine, inevitably increase fuel consumption, and easily lead to the destruction of the sc r system. Automotive urea is a liquid used in SC R technology to reduce nitrogen oxide pollution in diesel vehicle exhaust.

[Pacific Automobile Network] The emission of diesel nitrogen and oxygen compounds without urea solution is 4 times higher than that of diesel vehicles without urea solution. At the same time, due to the twist-limiting function of OBD, diesel vehicles with urea liquid are more powerful, while vehicles without urea are less dynamic. Urea, also known as carbamide, is a kind of white crystal.

diesel car urea

The so-called "urea" of diesel cars actually does not refer to urine, but to the urea solution used by drivers, which is the common name of exhaust gas treatment liquid. Automotive urea is a liquid used to reduce nitrogen oxide pollution in diesel exhaust. It is composed of 35% high-purity urea and 65% deionized water.

Diesel vehicles must add urea. If urea is not used, the vehicle engine will automatically slow down. Moreover, if the urea is not pure enough or the quality is poor, it will also cause the automatic slowdown of the vehicle engine.

Urea is added to diesel vehicles to reduce automobile exhaust emissions and protect the atmospheric environment.

Urea is added to cars mainly to meet emission standards.Only diesel vehicles can add urea. The state stipulates that electric injection diesel locomotives must add urea, because the exhaust emissions of diesel vehicles are relatively large. The addition of urea can reduce carbon-oxy compounds in the exhaust gas and reduce the emission of pollutants, thus making diesel vehicles more environmentally friendly.

Diesel vehicles plus urea is used to purify exhaust gas. All cars using diesel engines need to use urea to purify the exhaust gas, otherwise the exhaust emissions of diesel vehicles will exceed the standard. Gasoline cars do not need to use urea to purify the exhaust gas.
