TH5909C3 - Muffler For diesel cars - Google Patents

Abstract

DC60 (04/08/52) The exhaust muffler for diesel cars, according to this invention, has a whole structure made of shaped stainless steel. Outwardly cylindrical The internal structure is divided into 3 parts: the front structure. (Exhaust gas inlet) consists of 2 sets of perforated tubes covered with a cylindrical tube. With 4 curved fins fixed between 2 sets of cylindrical tubes and acts to control the flow of exhaust gas to flow along the curve of the fins causing black soot to accumulate in the cylinder in the inner wall Of muffle pot And central structure It consists of a cylindrical basket with a protrusion plate connected to the inner wall of the muffler. To help absorb loud sounds and Accumulated black smoke from the front structure of the muffler, next is the rear structure (exhaust gas outlet) consisting of four curved fins, which are used to control the flow of exhaust gases from the front. And the central part to flow along the curve of the fins causing most of the black soot to accumulate in the cylinder cage. And the volume of all exhaust gas will expand through the bell-shaped tube. The shell of the pot is rest. The outer surface has bolts attached to the top of the structure, the rear part and the bottom of the front section for filling the carbon black smoke inside the structure. The fabricated structure uses all stainless steel so it will not rust. Has a long service life Can add water to clean the internal structure of the pot. And when the exhaust gases flow through the structure of 3 parts continuously, it will make a noise. And reduced engine soot Muffler For diesel cars, according to this invention, the entire structure is made of stainless steel, the external shape is cylindrical. The internal structure is divided into 3 parts: the front structure. (Exhaust gas inlet) consists of 2 sets of perforated tubes covered with a cylindrical tube. With curved fins 4 welding fins are held between two cylindrical tubes and act to direct the flue gas flow along the curve of the fin. Causing black smoke to accumulate in the cylindrical basket on the inner wall of the muffler And the central frame It consists of a cylindrical basket with a protrusion plate connected to the inner wall of the muffler. To help absorb noise and accumulate black smoke from the front structure of the muffler, next is the rear structure. (Exhaust gas exit) consists of four curved fins, which are used to control the flow of exhaust gases from the front and center to flow along the curve of the fins, causing most of the black soot to accumulate in the cylinder. And the amount of all exhaust gas will expand through the bell-shaped tube. On the outer surface of the shell, the bolts are attached to the top of the rear and the bottom of the front. For adding water to the bottom, soot and black smoke inside the structure From the fabricated structure in all stainless steel, it will not rust. Has a long service life, can add water to clean the internal structure of the pot. And when the exhaust gases flow through the structure of the 3 gardens continuously, making noise And reduced engine soot

Claims (1)

Disclaimer (all) which will not appear on the advertisement page: 1 This invention Is the muffler For diesel cars Which has a structure consisting of 3 parts as follows: - Frontal structure It consists of an outer cover (16) for connecting the muffler, the front end is a stainless steel cylinder (6,12) with a 9,13 perforated tube inside and a curved fin ( 10) The head appearance uses a smaller bending radius than the fin components. Thus creating a volute that is used to control the flow of exhaust gas to flow out through the fin. And since there are four curved flanges fixed between the cylindrical stainless steel (6) and (12), there is an opening for the exhaust gas pressure to expand through, thus creating a spiral flow. The radial curve of the arc causes some of the black soot to be mixed with the exhaust gases. Spread into compression on the interior wall of the muffler. And adhesion around the cylinder cage (19) that is connected to the inner cover (14), the stainless steel nut (5) will be connected to the shell of the pot below for the discharge of water when washing. Clean the soot and black smoke inside the muffler. - central structure It consists of a cylindrical perforated stainless steel (2) inside and a protrusion plate (3) for bonding to the inner wall of the muffler shell. And inside there is no structure that impedes the flow, causing exhaust gases containing sooty black smoke to expand quickly and adhere to the large number of interpolation baskets (2) - the rear structure consists of a curved fin plate (22). That have the characteristics of The head uses a lower bending radius than the tip of the fin, thus creating a volute that directs the flue gas flow through the fin. And since there are four curved flanges connected between the inner cap (20) and the cylindrical stainless steel (12), there is an opening for the exhaust gas pressure to expand through, thus creating a spiral flow. The radial curve of the curved fins causes some of the black soot that is mixed with the exhaust gases to disperse, compressing the interior wall of the muffler. And adheres around the cylinder (30) that is connected to the inner cover (20). Next, there is a bell-shaped mouthpiece (27) to help absorb the exhaust gas pressure to make it easier. And connected to the inner cap (24) and the outer cover (28) with the unique characteristics The internal structure of the silencer is divided into 3 parts, with a curved fin plate with the characteristic of the head, using a less bending radius than the tip of the fin, thus creating a volute that controls the flow of exhaust gas to circulate. Out through the end of the four fins within the structure, the front and the end. And in the interior wall of the exhaust silencer, all 3 parts have a stainless steel cylinder that is used to collect black smoke and absorb engine noise. The outer shell of the muffler also has a stainless steel nut connected at the bottom, front and top, back. For adding water to the bottom to clean the black smoke
