Problems solved by technology
The air intake pressure after compression is high, and the matching displacement of the air compressor can be reduced to save costs, and at the same time reduce the failure of the air compressor such as oil leakage, but the air extraction after compression will cause air grabbing with the engine, which will affect the power of the engine

The invention relates to the technical field of pneumatic systems of vehicles and provides an air inlet system, a pneumatic system and an air inlet control method of an air compressor. One end of a first pipeline of the air inlet system is connected with a connecting pipeline between an air filter and a supercharger, and the other end of the first pipeline is connected with the air compressor through a first switching valve. One end of a second pipeline is connected with a connecting pipeline between the supercharger and an engine, and the other end of the second pipeline is connected with the air compressor through a second switching valve. On the basis of the air inlet system, a controller controls on and off of the first switching valve and the second switching valve according to air pressure data, measured by a pressure sensor, of an air cylinder and demanded air inlet amount of the vehicle engine, and switching between pre-compression air taking and post-compression air taking of the air compressor is achieved. According to the air inlet system, the pre-compression air taking and post-compression air taking of the air compressor are combined, the performance of the engine and the performance of the air compressor can be achieved simultaneously, and the influence of post-compression air taking on the performance of the engine is reduced while rapid air inflation of the air compressor is achieved and faults such as oil pumping of the air compressor are reduced.
Description
technical field [0001] The invention relates to the technical field of pneumatic systems of vehicles, in particular to an air intake system, a pneumatic system and an air intake control method of an air compressor. Background technique [0002] For the whole vehicle, the pneumatic system plays a key role, such as vehicle braking, pneumatic clutch, pneumatic power steering, pneumatic door and so on. Therefore, the whole vehicle has a greater demand for high-pressure air. The air compressor takes air from the engine intake pipe, the air compressor is connected to the cylinder, and relies on the mechanical power of the engine to provide high-pressure air for the vehicle's pneumatic system. [0003] At present, there are two forms of air intake for air compressors: air intake before compression and air intake after compression. [0004] In the form of air intake before pressure, that is, the air intake is taken after the air filter and before the supercharger, that is, the air...
