Technical Field
The utility model relates to a gasoline engine technical field, in particular to silencer structure of gasoline engine.
Background
Gasoline engines are engines that convert internal energy into kinetic energy using gasoline as a fuel. The power output by the gasoline engine can drive the vehicle to run, generate electricity and the like. However, since gasoline engines generate a large amount of noise in their exhaust gas, it is necessary to reduce the noise by providing a muffler. The noise of the gasoline engine set is in broadband spectrum characteristic, and the silencing equipment is required to resist high air flow speed, high temperature and high pressure, and is not afraid of water and moisture, and when the temperature rises, the performance of the silencer is not changed greatly, so that a micro-perforated plate composite silencer is mostly adopted. However, only by providing the minute holes, the reduction of noise is limited. There is a need to further develop a muffler capable of reducing exhaust noise.

Detailed Description
The essential features and advantages of the invention will be further explained below with reference to examples, but the invention is not limited to the embodiments listed.
As shown in fig. 1 to 3, the muffler structure of a gasoline engine of the present embodiment includes a base 1, a housing 2, a cylinder 3 and a silencer 4, wherein the cylinder 3 is disposed on the base 1. The cylinder 3 is provided with first through holes 31, the first through holes 31 are arranged on the surface of the cylinder 3 at intervals, one end of the cylinder 3 is provided with an opening 32, and the other end is closed. The silencing part 4 is sleeved outside the barrel 3, a silencing cover 5 is arranged in the silencing part 4, the silencing cover 5 surrounds the barrel 3, the silencing cover 5 is provided with a second through hole 51, and the first through hole 31 and the second through hole 51 are arranged in a staggered mode. The outer cover 2 is arranged on the base 1, and an air outlet 21 is arranged at the top of the outer cover 2. In the above technical solution, the air flow enters the silencer through the opening 32, is discharged to the periphery through the first through hole 31 on the cylinder 3, and can absorb sound through the silencing part 4, so as to reduce noise, and the silencing part can be made of sound-absorbing materials such as sound-absorbing cotton. By providing the second through holes 51 in the muffling cover 5, the second through holes 51 are staggered with respect to the first through holes 31, and the flow velocity and pressure of the air flow can be further reduced. When the airflow enters the housing 2, the space increases, and the sound can be further reduced. Through above-mentioned technical scheme, can reduce the carminative sound of gasoline engine, effective noise reduction.
In this embodiment, base 1 is equipped with mounting hole 11, and a plurality of mounting hole 11 are arranged and are the annular, dustcoat 2 is equipped with the mating holes 22, and a plurality of mating holes 22 are arranged and are the annular, and mating holes 22 correspond with mounting hole 11 and set up. Through the technical scheme, the base 1 can be locked with the outer cover 2 through the screws, meanwhile, the matching holes and the mounting holes which are distributed in an annular mode can be adjusted when the mounting holes are convenient to mount, and the air outlet orientation of the air outlet 21 can be adjusted.
In this embodiment, the opening 32 is directed downward, and the opening 32 is connected to the exhaust pipe 6, so that the air flow of the exhaust pipe can enter the cylindrical body 3 upward through the opening 32. In this embodiment, the opening 32 has a tapered inner cavity 321, so that the airflow can be more concentrated. The air outlet 21 is oriented in a horizontal direction. In this embodiment, the end of the exhaust pipe 6 is provided with an air intake cover 7, and the exhaust pipe is located on the side of the air intake cover 7, so that the airflow discharged from the gasoline engine firstly enters the silencing cavity of the air intake cover 7, and the flow rate of the airflow is buffered by the air intake cover 7.
