Is the cloud inner tail post-processing system supported by the engine factory

1. The body of the cloud engine constitutes the skeleton of the engine, which is the various mechanisms of the engine and each The installation foundation of the system is that all the main parts and accessories of the engine are installed inside and outside, bearing various loads. Therefore, the body must have sufficient strength and rigidity. The uselage group is mainly composed of cylinder block, cylinder liner, cylinder head, cylinder pad and other parts.

2. In fact, cloud power is one of the top three multi-cylinder diesel engines in China. ( If Cummins' business in China is merged, Yunnei ranks fourth), the first is Chai Wei, the second is Yuchai, and the third is Yunnai Power, but YunnaiMost of the power engines are diesel engines installed on light trucks and pickup trucks. Founded in 1956, it has a history of more than 60 years.

3. Yunnan. According to the query enterprise check APP, the Yunnei engine is produced by Kunming Yunnei Power Co., Ltd. The company is located in Jingjing Road, Jingkai District, Kunming Area, China (Yunnan) Free Trade Pilot Zone.

What is the working principle of the post-processing system

1. Selective catalytic reduction, abbreviated as SCR, is a kind of post-processing system. Its technical principle is that under the action of the catalyst, the reducing agent is used to selectively reduce nitrogen oxides into nitrogen and water in an oxygen-rich environment.

2. The truck post-processing system refers to how the mixed exhaust gas generated during the driving process of the truck is converted into low-emission exhaust gas through the post-treatment device.

3. Selective catalytic reduction (SCR) is an effective means of treating NOx in exhaust gas. The article describes the working principle and precautions of the SCR system.

Detailed explanation of the configuration of FAW autonomous engine post-treatment system of national six b

1. The national six B standard requires that the nitrogen oxide (NOx) emissions of gasoline vehicles be reduced to 50% of the original standard, and the particulate matter (PM) emissions to 30% of the original standard. This means that automobile manufacturers need to adopt more advanced engine technology and exhaust gas aftertreatment systems to meet stricter emission standards.

2. Get the bottom price for free. In terms of power, the Red Flag HS5 uses a 20T engine coded CA4GC20TD32, with a maximum power of 165kW. At the same time, it meets the national six emission standards. The CA4C20TD32 engine is actually used by Red Flag H7. The upgraded product of the code-named CA4GC20T engine can be said to be independently developed.

3. National 6b emissions are: carbon monoxide emissions are required to not exceed 500 mg per kilometer of driving; non-methane hydrocarbons are required to be more than 35 mg per kilometer of driving; nitrogen oxides are required to be emitted per kilometer of no more than 35 mg per kilometer of driving; and the pm emission per kilometer is required to be fine The particulate matter should not exceed 3 mg.

4. The national six B standard is based on the national six standards, which has stricter technical requirements for engines, fuel, lubricating oil, exhaust gas post-treatment systems, etc.

5. Technical level: In order to meet the national 6B emission standards, automobile manufacturers need to use more advanced technologies and materials, such as adopting efficient emission purification equipment, improving the thermal efficiency of the engine, etc., which also means that the vehicles purchased by consumers will be more high-end and advanced.
