Description

Technical Field

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

[0002] A supercharger is a device that increases the intake pressure of the engine cylinder. The air before entering the engine cylinder is first compressed by the supercharger to increase the density of the air, allowing more air to enter the cylinder, thereby increasing the power of the engine. With the development and application of large-bore engines, the temperature and pressure of the gas after supercharged by the supercharger are getting higher and higher, which will cause the temperature and pressure of the hose at the supercharger outlet to increase. Long-term use will cause the surface rubber of the hose to fall off, the rubber to crack and leak, and the rubber to the connected pipe to stick and bond. Utility Model Content
