1. **Ukuma Okubalulekile** I-Exhaust Gas Recirculation (EGR) Temperature Sensor (EGR TS) iyisici esibalulekile sokuhlola ohlelweni lwe-EGR lwezimoto. Iqondile kakhulu efakwe emnyango/uphuma kwe-EGR valve kanye neziteshi ngaphambi/nemva kwe-EGR cooler. Ngokubheka isikhathi sangempela ushintsho lokushisa kwegesi ephumayo, iguqula isignali yokushisa ibe isignali kagesi futhi ithumele kwi-Engine Control Unit (ECU). I-ECU ilungisa ngokunembile ukuvulwa kwe-EGR valve futhi ilawule ukusebenza kwe-cooler ngokusekelwe kule datha, ifinyelela ekuvumelaneni okuhle kwevolumu yokuphuma kwegesi nokushisa. Lokhu akunciphisi kuphela ukukhiqizwa kwe-nitrogen oxides (NOx) ngesikhathi sokushiswa kwemoto ukuze kuhlangabezane nemithetho eqinile yokukhishwa efana ne-China National Emission Standard VI (GB 18352.6-2016) kanye ne-Euro 6d, kodwa futhi kuvikela ukonakala kwe-EGR valve okubangelwa ukushisa okweqile nokuvinjelwa kokwakheka kwekhabhoni ngenxa yokushisa okuphansi. Kusebenza ohlelweni lwe-EGR lwezimoto ze-diesel, izimoto ze-petrol, kanye nezimoto ezihlanganisiwe. 2. **Imisebenzi Eyisisekelo** Ukumelana Nokushisa Okuphezulu & Ukuhlola Okunembile: Umkhawulo wokukala kokushisa uhlanganisa -40℃ kuya ku-850℃ (kuze kube ku-1000℃ kumamodeli okwenziwa ngokwezifiso okuphezulu). Ihlongozwe ngezici zokushisa okuphezulu kwegesi ye-EGR, ukunemba kokukala ku-±3℃ emkhawulweni oyinhloko we-200℃-600℃. Isebenzisa i-Type K thermocouple noma i-high-temperature NTC thermistor njengento yokuhlola ukuze ibambe kahle ukushintsha kokushisa kwegesi ephumayo; Impendulo Yesignali Esisheshayo: Isikhathi sokuphendula kwesignali singu-＜500ms (nxa ukushisa kushintsha ngo-50℃ ngendlela ye-stepwise). Isekela ukuphuma kwe-analog (0-5V/4-20mA) noma kwe-digital (CAN bus), enokulibaziseka okuphansi kokuxhumana ne-ECU, iqinisekisa ukulungiswa kwesikhathi sangempela kohlelo lwe-EGR; Ukuvikelwa Kokushisa Okweqile & Ukuhlolwa Kwephutha: Nxa ukushisa kwegesi ephumayo okukhonjwe kudlula umkhawulo wezokuphepha (isb. ＞850℃), kuthumela ngokuzenzakalelayo isignali yokuxwayisa ku-ECU ukuze kuqale ukuvalwa kwe-EGR valve ukuze kuvikelwe. Nxa isikhumbuzo sine-open circuit, short circuit, noma ukunemba okuphambene nokulinganiselwa, kudala amakhodi ephutha (isb. P0403/P0409) ukuze kube lula ukuxazulula izinkinga ngokushesha ngabantu abaphatha; Ukumelana Nezimo Ezibucayi: I-probe yenziwe nge-316L stainless steel, ukumelana nokugqwala kwegesi ephumayo (ukumelana nokugqwala kwe-sulfide kanye ne-nitrogen oxide). I-housing inenani lokuvikela le-IP6K9K, ikwazi ukumelana nokudlidliza kwekhamera yemoto (10-2000Hz) kanye nokuphazamiseka kwe-electromagnetic (EMC Class 4), ikwazi ukujolisa ezimweni zokusebenza ezishisayo nezinezinkinga zokungcola kwe-EGR pipelines. 3. **Izici Eziyinhloko & Izinzuzo** Ukumelana Nokushisa Okuphezulu & Ukuthembeka: Into yokuhlola iyakwazi ukumelana nokuguga kokushisa okuphezulu, inempilo yokusebenza ye-≥3 iminyaka noma ama-100,000 kilometers uma isebenza endaweni ye-800℃, idlula kakhulu umkhawulo wokumelana nokushisa wezikhumbuzo ezijwayelekile, ihlangabezana nezidingo zokuphindaphinda okuphezulu kokushisa kohlelo lwe-EGR; Ukuhambisana Okuphelele: Ithole i-IATF16949:2016 isitifiketi sohlelo lwekhwalithi lwezimoto kanye ne-ISO 14001:2015 isitifiketi semvelo, ihambisana ne-EU RoHS, China National Emission Standard VI, kanye ne-US EPA emission standards, iqinisekisa ukufinyelela kwemoto ehambisanayo; Ukufakwa Kalula & Ukuvumelana: Iphakela izixhumi ezithile ze-EGR pipeline ezifana ne-M18×1.5 ne-M20×1.5, ivumelana nokuhlelwa kohlelo lwe-EGR lwezimoto ezahlukene. Isekela ukufakwa okuqondile kwezinsiza zokuqala (OE-compatible, isb. izspecifications ezifanayo ne-Bosch ne-Continental) ngaphandle kokushintsha iziteshi; Ukuvumelana Kwezinhlaka Ezinhlobonhlobo: Ihambisana nezinhlobo ezahlukene ze-EGR systems (high-pressure EGR, low-pressure EGR), futhi isekela ukuhlola ukusebenza kwe-EGR cooler (kuqhathaniswa nokushisa kwegesi ngaphambi nangemva kokupholisa) ukusiza ukuhlela kahle ukuphathwa kokushisa kwemoto. 4. **Ukuvumelana** Ukufinyelela Kwezimoto: Ihambisana nezimoto eziphakathi kwe-diesel (isb. Volkswagen Touareg TDI, BMW X5 xDrive30d), izimoto zokuhweba (amathrekhi anzima: Dongfeng Tianlong, Foton Auman; amathrekhi alula: Jiangling Shunda, Foton Ollin), kanye nezimoto ezihlanganisiwe (isb. Toyota Prius Hybrid, BYD Song Pro DM-i), isekela izimoto zokukhishwa kwe-National V, National VI, Euro 5, kanye ne-Euro 6d; Ukuvumelana Kohlelo: Iphendukela ezindaweni ezibalulekile zokuhlola ezifana nomnyango/uphuma kwe-EGR valve ephezulu, i-EGR pipeline ephansi, kanye nomnyango/uphuma kwe-EGR cooler. Ingakwazi ukwenza ngokwezifiso ukujula kokufakwa kwesikhumbuzo (isb. 20mm/30mm) kanye ne-signali protocol (isb. SAE J1939) ngokwezidingo zamakhasimende. 5. **Ukusekela Kwesevisi** Ukuze uthole imininingwane ethile yepharamitha yezobuchwepheshe bomkhiqizo (isb. umfanekiso wokumelana nokushisa, umdwebo wezokufaka), uhlu lokuhambisana nezimoto, noma uhlelo lokuhlola lokubambisana lwe-EGR, sicela uxhumane neqembu lesikhungo sokukhonza ukuze uthole ukwesekwa okukhethekile; sinikeza ukuhlinzekwa kokufakwa kwesikhumbuzo mahhala kanye nezikhombisi zokulungisa kanye nokusekela kwezobuchwepheshe ngemva kokuthengisa ukuze kuqinisekiswe ukuvumelana okungaphazamiseki nohlelo lwe-EGR.
