Description

Technical Field

[0001] The utility model relates to the technical field of engines, and in particular to a compressor intake pipe assembly, an engine and a vehicle. Background Art

[0002] The compressor intake pipe is an important part of the diesel engine. It is installed at the rear end of the air filter and the front end of the supercharger. It plays a key role in the normal operation of the diesel engine. In the crankcase closed cycle setting, the oil that leaks into the crankcase needs to be separated by an oil-gas separator, and the separated oil is recycled and reused, and the separated gas is introduced into the supercharger through the compressor intake pipe for supercharging, and then passes through the intercooler and enters the engine for combustion.

[0003] When diesel engines are used in vehicle assembly, due to the differences in the structural layout of different engine models and vehicle models (the structural differences of different compressor intake pipes mainly lie in the position and angle of each air port), it is necessary to develop a variety of compressor intake pipes with different structures to meet the matching needs. However, the current compressor intake pipes are generally rubber pipes made of one-piece molding. A compressor intake pipe of one structural size can only meet the needs of one corresponding vehicle structure, and its versatility is poor.

[0004] In the prior art, the design and manufacture of the compressor intake duct is mainly designed according to the corresponding specific vehicle model structural layout requirements. Each vehicle model requires a specially designed and manufactured compressor intake duct assembly. Although the above method can meet the needs of a specific vehicle model for the compressor intake duct, once the vehicle model structural layout requirements change, the compressor intake duct needs to be redesigned and manufactured, which undoubtedly increases the cost of maintenance and replacement, and the manufacturing cost is relatively high. And because each vehicle model requires a specially designed and manufactured compressor intake duct, it is impossible to quickly respond to and meet customer needs, and it also reduces production efficiency.

[0005] Therefore, there is an urgent need for a compressor intake pipe assembly, an engine and a vehicle to solve the above problems. Utility Model Content
