Or similar structure.

German engineer Rudolf since 1892. Rudolph Diesel invented the diesel engine (Diesel Engine), changing the market for past engine applications. Since the diesel engine has the characteristics of generating higher torque at a medium and low speed compared to the past engine, it has a more practical effect of fuel economy and low carbon dioxide emissions. However, the diesel engine can produce high-efficiency engine power, and relatively emits more polluting exhaust gas. The main substances of the exhaust gas are nitrogen compounds (NO _x ) and ultra-fine aerosols (PM2.5), which are environmentally friendly. Quite hurt and threat.

Therefore, in the 1990s, the Italian high-speed Common Rail diesel engine was used to accurately control the diesel supply and fuel supply time into the cylinder, due to the pressure in the fuel supply pipe. High, and thus improve the effect of fuel atomization, so that the fuel is burned more completely and cleanly in the engine fuel room, and the noise and vibration are also greatly reduced, which becomes the standard for the development and design of the subsequent diesel engine. At present, diesel engines have improved environmental pollution compared to earlier designs, but their effects are still unable to meet today's environmental standards. Therefore, diesel engines often require additional exhaust gas recirculation systems, carbon particulate filters and diesel fuel. The emission reduction catalyst can effectively improve the emission of polluted exhaust gas.

The main purpose of the present invention is to provide a smart filter smoke muffler that improves the black smoke and odor of the exhaust gas emitted by the diesel engine to reduce the environmental pollution of the exhaust gas while reducing the noise generated by the engine exhaust gas. .

In order to achieve the above object, the smart filter muffler device of the present invention comprises: a body having one end as an engagement port and the other end as an exhaust port; and a cyclone mixing combustion chamber being disposed at the end of the body near the joint port, The cyclone mixing combustion chamber and each of the fuel injection pipe and a gas injection pipe extend to introduce the fuel and gas into the cyclone mixing combustion chamber, and the cyclone mixing combustion chamber has an ignition rod to ignite the gas and the fuel. And a microcomputer automatic control device electrically connected with the cyclone mixed combustion chamber to ignite the ignition rod and control the temperature of the cyclone mixed combustion chamber; thereby connecting the engine through the joint port of the body to exhaust the exhaust gas from the engine In the cyclone mixing combustion chamber, a large rotation of the gas is generated, and then uniformly mixed with the atomized fuel to be ignited and ignited by the ignition rod, and the high-heat is provided by the cyclonic combustion method, and the filter device in the exhaust of the diesel engine is captured on the ceramic filter. The black smoke particles are burned again to purify the engine exhaust.

The advantages of this new model over the prior art are: (1) elimination of 90~99% black smoke in the exhaust gas; (2) noise reduction of about 30dBA when reducing exhaust emissions; (3) use of a catalyst filter to reduce exhaust gas 96 % of odor; (4) Cyclonic combustion to reduce the regenerative capacity of black smoke particles and eliminate 98% of carbon particles in black smoke.

Due to the high-pressure condominium diesel engine produced in the 1990s, the exhaust gas including black smoke and incomplete combustion gas, the exhaust gas is still flammable in a high temperature environment, and the exhaust gas can be reduced by secondary combustion and filter catalyst conversion. Environmental pollution, therefore, the present invention creates a smart filter smoke silencer that supplies a cyclonic combustion environment that makes the exhaust gas high The high-temperature hot-spin type combustion, and the drainage structure in the smart filter smoke-removing device not only re-combust the exhaust gas but also reduce the emission noise volume. In addition, the present invention relates to a smart filter smoke suppressing device, in which a filter is connected to filter the burned gas, thereby reducing the emission of harmful substances into the environment.
