Silencer for gasoline engine of heavy truck

Abstract

The invention discloses a muffler for a heavy-duty gasoline engine, comprising a muffler shell and a muffler area, one side of the outer surface of the muffler shell is provided with a muffler inlet and a pressure gauge, and the inner outer surface of the pressure gauge is fixedly connected to the The outer surface of the upper end of the muffler inlet, the outer surface of the front end of the muffler shell is movably connected with a pop-up window, the outer surface of the upper end of the muffler shell is fixedly connected with a signal receiver, and the outer surface of the other side of the muffler shell is fixed A slanted refraction plate is connected, and the outer surface of one side of the slanted refraction plate is fixedly connected with a sound leakage pipe, and the outer surface of the upper end of the sound leakage pipe is fixedly connected with a sound leakage port. A muffler for heavy-duty gasoline engines according to the present invention can release the pressure urgently when the pressure is high, and can elastically expand and contract to intensify the conversion of sound waves into heat energy, and can also produce sound waves of the same frequency to offset the sound waves of gasoline engines, bringing better prospects for use.

Description

technical field [0001] The invention relates to the field of mufflers, in particular to a muffler for heavy-duty gasoline engines. Background technique [0002] With the rapid development of science and technology and the rapid improvement of people's living standards, people pay more attention to spiritual enjoyment, especially wanting a quiet space, but the rapid development of automobiles makes the world's noise aggravated, especially the noise of heavy truck gasoline engines, The muffler has been developed rapidly; the existing heavy-duty gasoline engine mufflers have certain disadvantages in use. First, the sound of the gasoline engine cannot be eliminated more thoroughly, so that the practicability of the heavy-duty gasoline engine muffler is greatly reduced. Secondly, the heavy-duty gasoline engine During the use of the muffler, if the pressure is too high, the muffler may burst, and there are certain safety hazards. Finally, the muffler of the heavy-duty gasoline eng...

[0002] With the rapid development of science and technology and the rapid improvement of people's living standards, people pay more attention to spiritual enjoyment, especially wanting a quiet space, but the rapid development of automobiles makes the world's noise aggravated, especially the noise of heavy truck gasoline engines, The muffler has been developed rapidly; the existing heavy-duty gasoline engine mufflers have certain disadvantages in use. First, the sound of the gasoline engine cannot be eliminated more thoroughly, so that the practicability of the heavy-duty gasoline engine muffler is greatly reduced. Secondly, the heavy-duty gasoline engine During the use of the muffler, if the pressure is too high, the muffler may burst, and there are certain safety hazards. Finally, the muffler of the heavy-duty gasoline engine can only eliminate the sound of a certain frequency, which is not comprehensive enough to bring a certain impact on people's use process. Therefore, we propose a muffler for heavy-duty gasoline engines
