Description

Micrometer-sized control gasoline engine air inlet channel Technical Field The utility model relates to the technical field of gasoline engine air intake, in particular to a micrometer-sized size control gasoline engine air intake channel. Background Under the background of modern petrol engine technical development, in order to realize more efficient combustion, lower emission and better dynamic performance, put forward higher requirement to the size control of intake duct, micron-sized size control can accurately adjust the internal structure size of intake duct, and then optimizes the air current characteristic of intake for the gas mixture that gets into the combustion chamber is more even, improves combustion efficiency. Along with the development of modern industry and the change of environment, various impurities are contained in the air, such as dust particles, tiny solid suspended matters, harmful gases and the like, in order to reduce the entry of the impurities, a filter screen is installed in some air inlets to filter, however, a great deal of problems exist in the use process of the existing filter screen, on one hand, after the filter screen filters the impurities for a long time, a large amount of impurities are easily accumulated on the surface of the filter screen, if the impurities are not cleaned timely, the filter screen is blocked, the air inlet resistance is increased once the filter screen is blocked, the air inlet amount of the gasoline engine is influenced, the power output of the gasoline engine is further reduced, the insufficient combustion is caused, the oil consumption and the pollutant emission are increased, on the other hand, the traditional filter screen cleaning mode is often dependent on manual disassembly and cleaning, the mode is complex in operation and needs to be stopped, the normal use of the gasoline engine is seriously influenced, and meanwhile, the frequent disassembly and installation of the filter screen can damage the connecting parts of the filter screen and the air inlets, the sealing performance is influenced, and the air inlet effect is further influenced. Disclosure of utility model In order to solve the technical problems, the utility model provides a micrometer-sized air inlet channel of a gasoline engine, which comprises an air inlet channel, wherein the surface of the air inlet channel is fixedly connected with a filter box, the inner wall of the filter box is fixedly connected with a mounting support block, the surface of the mounting support block is fixedly connected with a limiting slide bar, the surface of the limiting slide bar is sheathed with a mounting ring, the surface of the mounting ring is fixedly connected with a reset spring, the inside of the mounting ring is fixedly connected with an activated carbon filter screen, the inner wall of the filter box is provided with a collecting tank, and the inside of the filter box is provided with a cleaning mechanism; the cleaning mechanism comprises a driving motor, the output end of the driving motor is fixedly connected with a transmission shaft, the surface of the transmission shaft is fixedly connected with a plurality of cam blocks, and the surface of the driving motor is sleeved with a protective shell.
