Intelligent smoke exhaust improvement device

The present invention relates to an intelligent smoke exhausting improvement device for improving environmental hazards such as black smoke or odor of exhaust gas emitted from a diesel engine, and effectively reducing noise during exhaust gas discharge, and is particularly suitable for heavy engines and vehicles powered by diesel engines. Or similar structure.

Since 1892, German engineer Rudolph Diesel invented the new diesel engine (Diesel Engine), changing the application market of the past engine. Because the diesel engine has higher torque at lower and lower speeds than the past engine. The characteristics, therefore, have more obvious fuel-saving effect and low carbon dioxide emissions. However, the diesel engine can produce high-efficiency engine power, and relatively emits more polluting exhaust gas. The main substance of the exhaust gas is nitrogen oxides. (NO _x ) and ultra-fine aerosols (PM 2.5) are quite harmful and threatening to the environment and ecology.

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, the diesel engine has been designed in environmental pollution. Improved, but the effect is still not able to meet today's environmental standards, so diesel engines often need to add expensive exhaust gas recirculation system, carbon particulate filter and diesel The emission reduction catalyst can effectively improve the emission of polluted exhaust gas.

The inventors of the present invention have in view of the above-mentioned practical difficulties in the treatment of engine exhaust gas, particularly for diesel engines, and the lack of additional equipment to be improved, and hope to provide a breakthrough design to enhance practical effects, which is painstaking research and design. The group system, which combines the professional technical knowledge and practical experience of related product design and production for many years, and the results obtained from the research and design, finally develops an intelligent smoke exhausting improvement device of the present invention to provide users.

Bypass device can automatically control the micro-computer automatic control device with the back pressure setting value of the body. When the black smoke particles block the back pressure of the ceramic filter element, the microcomputer automatic control device can control the bypass device to open. The bypass valve will discharge most of the exhaust gas into the filter device to reduce the wind pressure and reduce the flow rate, so as to improve the burning time and efficiency of the black smoke particles on the ceramic filter to achieve automatic regeneration function, and When the back pressure reaches the set standard, the microcomputer automatic control device will control the bypass device to return to the normal intake state, and a cyclone mixing combustion chamber is disposed at the end of the body near the connecting pipe, and an electronically controlled fuel injection is inserted in front of the flow dividing device. The pre Each of the combustion chambers is plugged with an electronically controlled fuel injection plug and an ignition device connected to the fuel injection tube, and a gas combustion tube is connected above the pre-combustion chamber of the body to introduce fuel and gas into the pre-combustion chamber, and electronically controlled spraying The oil injection plug is controlled by the microcomputer automatic control device, so as to control the electronically controlled fuel injection plugging, the fuel is automatically injected when the fuel is injected, and the length of the different injection time can be set, and an ignition device is inserted into the pre-combustion chamber. In order to ignite the mixed fuel, a flow dividing device, and a plurality of split flow oblique ports, the engine waste smoke and the fuel oil are mixed and rotated to be heated and regenerated, and the flow dividing device is engaged with the pre-combustion chamber, and the cyclone mixing combustion chamber is arranged by a fixed clamp ring or a flange.
