Description

Low Back Pressure, PLC Controlled Intelligent Emission Control and Silencer The system Technical Area The invention applies to internal combustion engines, particularly diesel generators and industrial engines. Its applications relate to the fields of exhaust gas treatment and acoustic noise control. More specifically, the invention relates to diesel oxidation catalysts (DOC) and diesel particulate matter. Compact and integrated structure of after-exhaust treatment components such as the DPF filter. brought together inside and low back pressure of exhaust gas flow It is aimed at managing it in a way that will provide this. State of the Art Current exhaust systems use mufflers, diesel oxidation catalysts (DOC), and Diesel particulate filters (DPFs) are generally considered as independent units of equipment. It is mounted in different sections of the line. This traditional structure; high assembly space requirements, use of a large number of fasteners, high pressure losses and heat losses, sealing problems, and installation and maintenance costs This can lead to technical problems such as an increase in cases. Additionally, excessive back pressure in the motor can develop due to filter clogging. this can negatively affect its performance and the operational safety of the engine. This can pose a risk. Technical Problems That the Invention Aims to Solve The primary purpose of the invention is to improve exhaust emission control equipment and muffler functionality. by combining them within a compact and integrated system structure, the assembly area to reduce the number of connections and associated losses, and to maintain the system. The goal is to increase its ease of use. 1 However, among the aims of the invention is; the exhaust gas within the system Reducing back pressure by regulating flow, the DOC and DPF components are the same. to position inside the exhaust system and take temperature and pressure measurements. This involves creating connection points that provide opportunities. Solutions and Advantages of the Invention The invention consists of inlet and outlet fittings, and an inlet, within a common exhaust system. and outlet cones, DOC unit, DPF unit, quick clamps, integrated insulation and relies on the combined use of temperature / pressure sensor connections. Exhaust gas is drawn into the system via the inlet flange (20) and the inlet cone (30) It is directed to the DOC unit (40) via. Gas passing through the DOC unit (40), It is directed to the DPF unit (60) and then exits through the outlet cone (70). It is transferred to the flange (80). Quick clamps (50) are used for connections between the relevant modules of the system. to facilitate the implementation and maintenance / disassembly processes Integrated insulation (90) provides thermal management around the system components. It contributes to its provision. Inlet pressure sensor connection (100) and outlet pressure sensor connection (110), measuring the pressure values ​​at the inlet and outlet sides of the system; inlet temperature sensor connection (120) and output temperature sensor connection (130) It allows for the measurement of temperature values. Explanation of the Figures Figure 1: Technical view of the 3.5-inch application of the invention. Figure 2: Technical view of the 6-inch application of the invention. Figure 3: Technical view of the 5-inch application of the invention. 2 Detailed Description of the Invention The invention's system has different inlet and exhaust line applications depending on the engine and exhaust line. A modular after-exhaust treatment and muffler that can be produced in various outlet diameters. It is the structure. The submitted technical drawings show 3.5-inch, 5-inch, and 6-inch applications. Examples are available. In the drawings, the system length is given as 930 mm. It has been shown. The inlet flange (20) allows the gas from the exhaust line to be drawn into the system. Inlet The cone (30) allows passage from the inlet section to the treatment components within the system. DOC unit (40) measures the oxidation reactions in the exhaust gas. It forms the catalytic section for its implementation. The DPF unit (60) is located after the DOC unit (40). DPF unit (60) can be configured as a SiC-based particulate filter in particular. From the DPF unit Then, a transition is made from the outlet cone (70) to the outlet flange (80). Quick clamps (50) are used for connections between the relevant modules of the system. to facilitate the implementation and maintenance / disassembly processes Integrated insulation (90) provides thermal management around the system components. It contributes to its provision. Inlet pressure sensor connection (100), outlet pressure sensor connection (110), inlet temperature sensor connection (120) and outlet temperature sensor connection (130), connection points for measuring the operating parameters of the system It creates. PLC Controlled Bypass System – Technical Verification The PLC operates according to pressure and temperature data in the current source specification. a controlled bypass valve and filter line can be deactivated when necessary. The act of releasing / guiding has been described as one of the elements of the invention. 3 Reference Marks Reference Part / Element Integrated exhaust system / system body Inlet flange inlet cone 40 DOC units 50 Quick Clamps 60 DPF units (SiC) 70 Exit cones 80 Outlet flange 90 Integrated insulation 100 Inlet pressure sensor connection (P1) 110 Outlet pressure sensor connection (P2) 120 Inlet temperature sensor connection (T1) 130 Output temperature sensor connection (T2) 140 Bypass valve 150 Bypass line 160 Electric Actuators 170 Serving Lids 180 PLC Control Unit 4
