New description: [New technical field] This creation relates to a method for effectively removing carbon deposits from a filter device installed at the rear end of a diesel engine exhaust pipe to maintain a smooth discharge of exhaust gas from a diesel engine. [Prior Art] Diesel engine vehicles ignite diesel or alternative fuels by compression ignition. After the combustion reaction in the cylinder, the chemical energy of the fuel is sequentially converted into heat energy and power output, so the combustion process is also Produces a variety of gas, liquid, solid pollutants, the most important are granular (PM), black smoke (smoke), nitrogen oxides (ΝΟχ) and so on. It also emits gaseous pollutants such as carbon monoxide (C0), sulfur oxides (S0〇, carbon dioxide (C〇2), and hydrocarbons (HC), causing global environmental damage such as ozone depletion, acid rain, and greenhouse effect. Destruction problems also cause harm to human health, so it is of concern to the public. For example, nitrogen oxides form acid rain through the formation of nitric acid, which also breaks the bad ozone layer and acts with sunlight to produce actinic smoke; granular pollutants or black smoke. If polycyclic aromatic hydrocarbons (PAHs) or metal compounds are present, it may cause lung, trachea, respiratory tract and other diseases. According to the TED4.2 version of the national air pollution source discharge database, the estimated data shows 3% of the national mobile The number of vehicles with diesel emissions is 46% PM and 51% of all mobile pollution sources. In particular, almost all national passenger and cargo operators use diesel vehicles as transportation vehicles. Therefore, how to prevent diesel vehicle exhaust pollution by prevention technology or control strategy In order to improve the air quality, it is an important issue today. 4 The car industry that has witnessed has been constantly proposing various solutions. The method is to use the over-age system installed in the rear end of the exhaust pipe of the diesel engine. The exhaust gas of the effective overage oil engine is more than the sister. However, this kind of loading engine is the end of the system. - The carbon formed by the segment will cause blockage at the core, which will not only affect the effect of the exhaust gas from the diesel engine, but also affect the function of the diesel engine. The exhaust gas from the diesel engine passes through the filtration system. After that, carbon deposits will be generated in the enthalpy of the over-the-counter system. When the carbon deposit reaches a certain thickness, a blockage will occur, resulting in an increase in the pressure (back pressure) in the exhaust pipe. Therefore, the automobile industry is currently backing. The pressure sensor is installed in the pressure value of the diesel engine to correct the tracheal swaying over the ageing filter, and thus can detect the blocked state of the carbon deposit, and the exhaust gas of the diesel vehicle engine passes through the filter system. When the thickness of the exhaust clogging is detected, an elevated exhaust back pressure is detected. At this time, the engine management system will send a signal to raise the working temperature of the engine and deposit carbon on the filter surface of the filter system. Burn off, to eliminate the filter plug. But because the car environment is not good (such as Taiwan's major metropolitan areas) 'vehicles often stop and go' 妓 personal wealth (Mr. often on the highway), often idle Driving in the state, so that the diesel vehicle equipped with the filtration system may not be able to increase the operating temperature of the engine because the engine speed is not high, and it is impossible to burn the carbon accumulated on the surface of the filter system, which not only affects the filtered diesel. The effect of the engine exhausting the exhaust gas, and affecting the normal operation of the diesel engine. At this time, the car can only be driven to the car service factory. The technician burns the carbon on the surface of the old age, which is not only time-consuming but also uneconomical. Very troublesome.

The new patent of Taiwan M362299 "Dust-smoke and transient combustion purification device for diesel vehicles" approved by the applicant in this case is located in the exhaust pipe from the inlet end to the outlet end. When the pressure of the exhaust gas in the exhaust pipe is higher than the preset value by the helium-pressure sensor, the microcomputer control system sends the oil to the -__ box, and the material is supplied to the ship. The four-year-old material is used to heat the simultaneous ignition tank in the combustion system to about 働. c, let the gas heated to high temperature pass through the system, to ignite the carbon deposit, and when the second pressure sensor measures the exhaust gas pressure below the preset value, then the micro-electricity (10) The fuel is supplied from the __ bin, so that the exhaust gas generated by the diesel engine is naturally discharged through the transition system to maintain the smooth discharge of the diesel engine.

Smooth problems with the performance of diesel engines. Another purpose of this creation is to improve the Taiwan M362299 patent case where the ignition device is placed on the path of the exhaust gas flow passage so that it is easily blown out by the air flow during ignition, which causes the carbon deposition of the filtration system to be incomplete. . The main feature of this creation is that a combustion system and an exhaust gas buffer filtration system are sequentially arranged in the direction from the intake end to the outlet end of the exhaust pipe; when the exhaust gas passes through the combustion system®, it is forcibly diverted through a plurality of air guiding passages. Then, after the fuel is sprayed and atomized by the fuel atomizing nozzle which is not blown by the exhaust gas flow, the igniter is immediately ignited and burned, and the exhaust gas flow passing through the air guiding passage uses the siphon to heat the burned chamber. Aspirating to increase the exhaust gas temperature by mixing the exhaust gas; the high-temperature exhaust gas sequentially passes through the exhaust gas buffer unit and the filtering unit of the exhaust gas buffer filter system, uses the exhaust gas buffer unit to slow down the exhaust gas flow rate, and avoids the exhaust gas recirculation to blow out the ignited flame, and The exhaust gas flow is homogenized and then passed through the filter unit' to further remove the carbon accumulated in the filter unit by the high temperature of the exhaust gas to maintain the smooth discharge of the diesel engine exhaust gas.
