What Kind of Air Compressor is Suitable for National V Vehicles?96

With the continuous improvement of China's environmental protection requirements, the emission standards for vehicles have also been continuously upgraded. At present, the national emission standards for vehicles in China have reached the National VI level. For vehicles with different emission standards, the requirements for car air compressors are also different. So, what kind of car air compressor is suitable for National V vehicles?

Characteristics of National V Vehicles

National V vehicles are vehicles that meet the emission standards of the fifth stage of the "Emission Standards for Light-Duty Vehicles" (GB18352.5-2013). Compared with National IV vehicles, National V vehicles have stricter requirements on exhaust emissions, especially in terms of particulate matter (PM) and nitrogen oxides (NOx). The emission limits for PM and NOx have been reduced by 40% and 30% respectively compared with National IV vehicles.

Requirements for Air Compressors for National V Vehicles

Due to the stricter emission standards of National V vehicles, the air compressors used on these vehicles must also meet higher requirements. The main requirements are as follows:
Higher air flow rate: National V vehicles have higher requirements for air intake, so the air compressor must have a higher air flow rate to meet the needs of the engine.
Lower noise: National V vehicles have stricter noise limits, so the air compressor must have lower noise to reduce the overall noise of the vehicle.
Better durability: National V vehicles have longer warranty periods, so the air compressor must have better durability to ensure long-term stable operation.

Types of Air Compressors Suitable for National V Vehicles

There are two main types of air compressors suitable for National V vehicles: diaphragm air compressors and rotary vane air compressors.
Diaphragm air compressors: Diaphragm air compressors use a diaphragm to compress air. They have the advantages of simple structure, low noise, and good durability. However, their air flow rate is relatively low.
Rotary vane air compressors: Rotary vane air compressors use rotating vanes to compress air. They have the advantages of high air flow rate, good efficiency, and low noise. However, their structure is more complex than diaphragm air compressors.

For National V vehicles, rotary vane air compressors are generally more suitable. This is because rotary vane air compressors have a higher air flow rate, which can better meet the needs of the engine. In addition, rotary vane air compressors have lower noise, which can help to reduce the overall noise of the vehicle.

Recommended Air Compressor Brands for National V Vehicles

There are many brands of air compressors on the market, but not all brands are suitable for National V vehicles. The following are some recommended air compressor brands for National V vehicles:
Bosch: Bosch is a world-renowned auto parts manufacturer. The air compressors produced by Bosch have excellent performance and are widely used in various vehicles, including National V vehicles.
Denso: Denso is a Japanese auto parts manufacturer. The air compressors produced by Denso are also of high quality and are used in many Japanese vehicles, including Toyota and Honda.
Hitachi: Hitachi is a Japanese electronics and machinery manufacturer. The air compressors produced by Hitachi are also of high quality and are used in many Japanese vehicles, including Nissan and Mazda.

When choosing an air compressor for a National V vehicle, it is important to consider the following factors:
The air flow rate of the air compressor should be greater than or equal to the air intake requirements of the engine.
The noise of the air compressor should be as low as possible to reduce the overall noise of the vehicle.
The durability of the air compressor should be good to ensure long-term stable operation.

By following these guidelines, you can choose the right air compressor for your National V vehicle.
