Problems solved by technology

[0002] The working environment in coal mines and other places is harsh. When trucks are loading coal in coal plants, unloading coal in power plants, and transporting coal on roads, due to excessive dust content in the air, the filter elements in the filter are often blocked, resulting in engine power loss and fuel consumption. Different degrees of increase will increase the frequency and cost of car owners to replace filter elements, which will bring inconvenience to car owners; currently, when ordinary mufflers are used in the exhaust system of automobile engines, the filter elements need to be maintained once every two or three days, which reduces the use of filter elements Life, and increase the cost of the owner, bring inconvenience to the owner

Abstract

The invention provides an exhaust gas ejection muffler. An exhaust gas ejection port and a gas inlet are formed in one side of a shell, and an exhaust port is formed in the lower part of the shell, wherein a Venturi tube is arranged in the shell; the exhaust gas ejection port is connected with an inlet in one side of the Venturi tube; the gas inlet is connected with the rear part of the Venturi tube; the exhaust port is connected with an outlet in the lower part of the Venturi tube; the Venturi tube is connected with the shell through brackets comprising brackets 1 and 2. Compared with the prior art, the exhaust gas ejection muffler has the advantages that the muffler is communicated with a filter under the condition of no influence on the performance of the muffler, and negative pressure is generated in the muffler to suck dust away from a filter element of the filter, so that the service life of the filter element is prolonged, the replacement frequency of the filter element can be reduced, the maintenance period of the filter element is prolonged, and the cost is lowered.

Description

technical field [0001] The invention relates to a muffler for an automobile engine exhaust system. Background technique [0002] The working environment in coal mines and other places is harsh. When trucks are loading coal in coal plants, unloading coal in power plants, and transporting coal on roads, due to excessive dust content in the air, the filter elements in the filter are often blocked, resulting in engine power loss and fuel consumption. Different degrees of increase will increase the frequency and cost of car owners to replace filter elements, which will bring inconvenience to car owners; currently, when ordinary mufflers are used in the exhaust system of automobile engines, the filter elements need to be maintained once every two or three days, which reduces the use of filter elements life, and increased the cost of the owner, to the owner of the inconvenience. Contents of the invention [0003] The purpose of the present invention is to overcome the above-ment...
