Problems solved by technology
However, while improving the performance of the exhaust muffler, it will also have a certain negative impact on the performance of the engine, such as power reduction, fuel consumption increase, etc., which violates the requirements of the automotive industry for energy conservation and environmental protection. Therefore, a muffler with good noise reduction performance has been developed. At the same time It is very important to take into account the engine's power, fuel economy and other requirements

The invention discloses a particulate matter purifying and noise elimination integrated device comprising a cylindrical shell body which comprises an upper shell body and a lower shell body. The interior of the shell body is divided into two cavities through a supporting cover, wherein the first cavity is located between the lower shell body and the supporting cover, and the second cavity is located between the upper shell body and the supporting cover. Air holes communicating with the two cavities are formed in the periphery of the surface of the supporting cover. A longitudinal perforated pipe is arranged inside the first cavity. A filter element is arranged outside the longitudinal perforated pipe. One end of the longitudinal perforated pipe penetrates through the bottom wall of the lower shell body to form an air inlet. An air exhaust outlet is formed in one side of the upper shell body. A transverse perforated pipe is arranged inside the second cavity. One end of the transverse perforated pipe is of a closed structure, and the other end of the transverse perforated pipe communicates with the air exhaust outlet. The particulate matter purifying and noise elimination integrated device has good performance of high mechanical strength, high-temperature resistance and the like and good anti-impact performance, and using of off-road vehicles is achieved.
Description
technical field [0001] The invention relates to the field of after-treatment control of motor vehicle exhaust, relates to a device integrating particle purification and noise reduction, in particular to a diesel engine particle purifier using stainless steel fiber as a filter material, which is effective in pressure drop, replacement convenience and reliability Exhaust particulate matter trapping device with strict requirements. Background technique [0002] Due to the incomplete combustion of the diesel engine during the combustion process, the emissions contain a large amount of particulate matter (PM), which consists of hundreds of organic and inorganic components. The main components of the particulate matter include soot particles (41%), unburned Fuel (7%), lubricating oil (25%), sulfate and water (14%), and ash (13%), etc., these components are the same as the elements of soot particles, and the percentage changes are different from the type and use of diesel engines ...
