Embodiment Construction
[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0017] refer to Figure 1-2 , a diesel engine muffler, comprising an intake pipe 9 and an exhaust pipe 3, one end of the intake pipe 9 is connected with a coaxial intubation pipe 8, the diameter of the air intake pipe 9 is smaller than the diameter of the intubation pipe 8, and the outer wall of the intubation pipe 8 Small holes 7 are densely distributed on it, and one end of the exhaust pipe 3 is connected with a coaxial casing 6, and the inner wall of the casing 6 is evenly distributed with strip-shaped ribs 19. The diameter of the exhaust pipe 3 is smaller than the diameter of the sleeve pipe 6, and the insertion pipe 8 is inserted inside the sleeve pipe 6 and the...

The invention relates to the technical field of mufflers, in particular to a diesel engine muffler. The diesel engine muffler comprises an air inlet pipe and an exhaust pipe. One end of the air inletpipe is connected with an insertion pipe coaxial with the air inlet pipe, and the diameter of the air inlet pipe is smaller than the diameter of the insertion pipe, and small holes are densely distributed in the outer wall of the insertion pipe. One end of the exhaust pipe is connected with a sleeve pipe coaxial with the exhaust pipe, the diameter of the exhaust pipe is smaller than the diameter of the sleeve pipe, the insertion pipe is inserted into the sleeve pipe, and a gap is reserved between the insertion pipe and the inner wall of the sleeve pipe, and annular sealing blocks are connectedbetween the end part of the sleeve pipe and the end part of the insertion pipe. According to the diesel engine muffler, a plurality of sections of connecting pipes are adopted for nesting, and air, silencing cotton and other materials can be sealed between the connecting pipes, so that the silencing effect is improved; in addition, the joint is in threaded connection, so that disassembly and maintenance are facilitated.
Description
technical field [0001] The invention relates to the technical field of mufflers, in particular to a diesel engine muffler. Background technique [0002] The automobile muffler is mainly used to reduce the noise generated when the engine of the motor vehicle is working. The principle is that the automobile exhaust pipe is composed of two pipes with different lengths. The difference is equal to half of the wavelength of the sound waves emitted by the car, so that the two columns of sound waves interfere with each other when they are superimposed to cancel each other out and weaken the sound intensity, so that the transmitted sound is reduced, thereby achieving the effect of noise reduction. However, the silencer in the prior art has a general sound reduction effect, and is inconvenient to disassemble and thus inconvenient to maintain. Contents of the invention [0003] The object of the present invention is to solve the disadvantages of poor effect and inconvenient maintena...
