Ukushintsha izimoto zethu kwaqala ukungenwa yigciwane kusukela kwasungulwa imoto yokuqala. Sonke sihlala sifuna okuthile okuzokwenza izimoto zethu zihluke futhi zihehe emgwaqeni. Njengoba umkhiqizo owodwa ungenele nje ukuhambisana nazo zonke izidingo, Max Racing Exhaust inikeza uhla olukhulu lwemikhiqizo ekuvumela ukuthi ujabulele intshiseko yokuguqula nokwenza ngokwezifiso izimoto zakho.
Isistimu ye-exhaust yaklanyelwe ukunciphisa ukungcoliswa kwamagagasi omsindo nokulawula izinga lokukhishwa kwenjini yomlilo yangaphakathi (ICE). Kunocwaningo oluningi nentuthuko eyenziwa kuleli gama ukukhulisa ukusebenza kwenjini ngaso sonke isikhathi, okuhlanganisa nathi. Nakuba isistimu ye-exhaust yayidinga imiklamo eyinkimbinkimbi yohlelo ngalunye oluhlukile, okuyisisekelo akushintshi: donsa amagesi avuthayo asuka ku-valve yokukhipha umoya, ikhiphele emkhathini ukuze uqinisekise ukuthi umjikelezo wokuvutha usebenza kahle. Okuguquguqukayo okubalulekile okushintshayo kuye ngezinhlelo zokusebenza ubude bepayipi, ububanzi, i-radius yokugoba, ivolumu ye-muffler kanye nomklamo we-baffle wangaphakathi kuthinta ukusebenza.
Ukukhetha i-exhaust efanele kungase kudideke futhi kudle isikhathi. Nakuba iningi lomsebenzisi likhetha isistimu yokukhipha umoya esekelwe emsindweni nasekubukekeni kuphela, kubalulekile ukuqaphela ukuthi ukuze kuzuzwe ukusebenza kahle, ubukhulu obufanele bepayipi kufanele bufaniswe nenhlanganisela yenjini, futhi okubaluleke kakhulu ububanzi be-rpm yamandla athile amahhashi. . Ngakho-ke, uma usebenza, thina, Max Racing Exhaust silapha ukuze sikunikeze isixazululo sokuqonda okuyisisekelo kwe-exhaust kanye nokukhetha okufanele ukufanisa nesistimu yokukhipha umoya elandelayo yemoto yakho.
Ukuze usebenze kahle, ukucushwa kwesistimu ye-exhaust kufanele kufaniswe nesistimu yokungenisa izinjini, osayizi bamasilinda kanye nesikhathi se-camshaft. Lezi zingxenye kufanele zishunwe ndawonye njengesistimu edidiyelwe yokusebenza okuphezulu kakhulu phakathi kwebanga elithile le-rpm. Uma ingxenye eyodwa ilungiswa, lonke iqembu lezingxenye kufanele libuyiselwe ukuze kulinganiswe ukusebenza okuphezulu.
Isistimu yokukhipha umoya ethuthukisiwe ifinyelela ibhalansi yengcindezi phakathi komthamo wenjini kanye namapheshana e-exhaust ngaphakathi kwebanga le-rpm elinikeziwe. Isibonelo se umgijimi womgwaqo, uma ufuna i-torque ethuthukisiwe endaweni ephansi naphakathi nendawo (2,500-4,500 rpm) ukuze uthole ukusheshisa okuhle kakhulu nokuhamba ngomgwaqo omkhulu kanye namandla ahloniphekile ekugcineni okuphezulu. Kodwa-ke, yonke imiklamo yamapayipi iwukuyekethisa. Isibonelo, uma ipayipi lidizayinelwe kuphela itorque engezansi, izoyeka amandla amahhashi aphezulu futhi ngokuphambene nalokho. okwamanje, ngoba abagijimi, izinjini ezinkulu zamahhashi amakhulu zivame ukuklama ipayipi lamandla aphezulu futhi zizokwehlisa i-torque ephansi, ngakho imoto izoqalisa kalula, okuholela ekusheshiseni ngokushesha. Isistimu yokukhipha umoya isebenza kuphela ngebanga elincane lebhendi yonke ye-rpm yenjini, ngakho-ke okubalulekile kufanele kubekwe futhi kuxegiswe ukuze kuzuzwe izici zokusebenza ezifiselekayo. Izingxenye ezinkulu zesistimu yokukhipha umoya zifaka i-exhaust header/ manifold, isiguquli se-catalytic, i-exhaust resonator, kanye ne-exhaust muffler. Ububanzi, ubude kanye nokucushwa komklamo jikelele kwalezi zingxenye kuzoba nomthelela omkhulu enjinini.
I-Exhaust Pipe Diameter
Idayamitha yepayipi ingenye yezingxenye ezibalulekile zokuthuthukisa ukusebenza kwemoto ngoba ububanzi bayo bunquma inani levolumu okufanele ligeleze kulo elinomthelela omkhulu esivinini segesi yokukhipha umoya. Ndawonye, ukugudluzwa kwenjini, isilinganiso sokuminyanisa, ububanzi be-valve, ukucaciswa kwe-camshaft kanye nebhendi ye-rpm kunquma ububanzi obufanele. I-exhaust backpressure izokhula uma ububanzi bepayipi buncane kakhulu. I-Backpressure ukumelana nokugeleza okudalwe ohlelweni lwe-exhaust. I-backpressure ephezulu inyusa ukulahleka kokupompa kwenjini, okuholela ekwenyukeni kwengcindezi ku-piston phakathi nomjikelezo wokukhipha umoya.
Ukwengeza, i-backpressure ephezulu inciphisa ukugeleza kokukhipha okuphansi ngesikhathi "sokushaywa". I-Blowdown yinto yokwandisa amagesi e-exhaust okusiza ukukhipha izinsalela zomlilo kusilinda futhi kuqala lapho kuvulwa ivalvu yokukhipha umoya. I-Blowdown isho indlela izinsalela zokuvutha ezikhishwa kahle ngayo kusilinda ngokwandisa amagesi okukhipha umoya. I-Blowdown iqala lapho i-valve yokukhipha umoya ivuleka futhi iphele lapho ukucindezela kwesilinda kanye nokucindezela kwesistimu yokukhipha amandla kulinganisa. Ukusebenzisa i-blowdown ukusiza ukukhipha amagesi e-exhaust kunciphisa ukulahlekelwa kokupompa kwenjini ngoba izidingo zomzimba ezincane zifakwa ku-piston phakathi nomjikelezo we-exhaust. Isimo esikahle siwukuba nebhalansi phakathi kwe-backpressure kanye ne-exhaust gas velocity. Ububanzi bepayipi elikhulu ngokwedlulele buzonciphisa umfutho obuyayo kodwa futhi kwehlise isivinini, kubangele itorque ephansi ephansi.
Ipayipi Lokukhipha Ubude
Ubude bepayipi bunqunywa uhlelo lwenjini (ukuvakasha, umgwaqo oshisayo, umjaho, njll.) kanye nobubanzi be-rpm. Ubude bepayipi bulawula inertia nokushuna kwamagagasi, okusungula umthelela wokukhipha amandla ekukhiqizweni kwamandla. I-Scavenging isebenzisa ikholomu yamagesi e-exhaust ahamba ngokushesha (i-inertia scavenging) noma i-supersonic energy pulse (i-wave scavenging) ukusiza ukuhlanza izinsalela ezivuthayo kusilinda. I-inertia kanye ne-wave scavenging nakho kungasiza ukushaja okungenayo kusilinda. Ngesikhathi sokusebenza kwenjini, amagagasi amahle namabi adalwa ohlelweni lokukhipha umoya futhi abuyele emuva naphambili kulo lonke ubude bepayipi. Uma ubude bepayipi buthuthukisiwe, igagasi elingalungile lizobekwa isikhathi ukuze lifike ku-valve yokukhipha umoya ngesikhathi sokugqagqana kwe-valve. Igagasi elingalungile elibekwe isikhathi ngendlela efanele lizonciphisa ukucindezela ku-valve futhi lisize ukuxosha amagesi avuthayo avela ekamelweni. Ibhendi yenjini ebaluleke kakhulu ye-rpm kufanele ikhonjwe ukuze ubude bepayipi bufaniswe ne-rpm efanele ngenxa yokuthi amaza omfutho angakwazi ukubekwa isikhathi kuphela ukusiza ukukhipha ukungcola ebangeni elincane le-rpm. Ubude bepayipi elide buthuthukisa amandla nge-rpm ephansi kuyilapho ubude obufushane buthuthukisa ukusebenza kwesiphetho esiphezulu.
I-Exhaust Muffler
Isistimu ye-exhaust kufanele ibe nevolumu eyanele ye-muffler ukuze ugcine ukucindezela okungemuva kuphansi nge-rpm ephezulu. Ukususwa kwenjini, isilinganiso sokucindezela, i-rpm, namandla ehhashi zonke izici ezinquma ivolumu ye-muffler eyanele. Ngokuvamile, ivolumu ye-muffler kufanele ibe cishe izikhathi ezingu-10 kunomthamo we-cylinder ukwenza amandla anele e-rpm aphezulu. Kodwa khumbula ukuthi njengoba amandla ehhashi enyuka, umthamo wegesi ephumayo nawo uyanda. Ngokukhuphuka kwevolumu yegesi yokukhipha, ukugeleza komoya kwe-muffler, nevolumu nakho kufanele kwandiswe. Lokho kusho ukuthi injini engu-96ci ekhiqiza amandla amahhashi angu-100 ikhiqiza amagesi e-exhaust amaningi kunenjini efanayo ekhiqiza amandla amahhashi angu-90 kuphela futhi idinga umthamo omkhulu we-muffler ukuze uthole amandla aphezulu aphezulu. Ngeshwa, ama-muffler amakhulu awathokozisi ngobuhle enjinini ye-V8, ngakho-ke kuyinselele ukuklama isistimu yokukhipha umoya wezinjini ezinkulu ezisuthisa kokubili ubuhle nokusebenza.
Amasistimu e-exhaust amabili-kubili asebenzisa ama-muffler e-exhaust amabili, anikeza amandla okwanda kwevolumu ye-muffler. Imiklamo enjalo futhi ijwayele ukufundeka ngokuguqulwa kwama-baffles angaphakathi. Ukwandisa inombolo kanye/noma usayizi wezimbobo ku-baffle noma ukunciphisa ama-baffle kunciphisa ukucindezeleka okungemuva futhi kungasiza amandla aphezulu. Noma kunjalo, khumbula ukuthi ukugeleza okwandayo kakhulu kungabulala i-torque esekupheleni. Ukwengeza, uhlelo lwe-2-into-1 oluguqulekayo lunikeza inzuzo enkulu ngaphezu kwesistimu yokuqoqwa engashintsheki, ikakhulukazi uma umthamo wenjini mkhulu.
iziphetho
Nakuba abashayeli abaningi bethenga i-exhaust system esekelwe kumsindo nokubukeka okudonsa amehlo, khumbula ukuthi ukuze usebenze kahle, ububanzi bepayipi, ubude kanye nomklamo kubalulekile. Cabangela i-exhaust system njengengxenye yenjini esemqoka okufanele ishuniselwe ukususwa kwenjini, i-cam kanye ne-induction system. Idayamitha yepayipi yokukhipha umoya ngokuvamile iyisici esibaluleke kakhulu ekwakhiweni kwesistimu yokukhipha umoya ngoba ibeka ijika letorque. I-diameter enkulu ithuthukisa amandla aphezulu ngezindleko ze-torque ephansi. Ukushintsha ubude bepayipi kuhambisa ijika letorque phezulu noma phansi kwebhendi ye-rpm. Ubude obufushane ngokuvamile buthuthukisa amandla amahhashi aphezulu kuyilapho ipayipi elide likhuphula i-torque yesiphetho esiphansi. Amapayipi aqondile ngokuvamile athuthukisa amandla angaphezu kuka-4,000 rpm kodwa anciphisa ukusabela kwe-throttle kumabanga aphansi we-rpm. Okokugcina, uma ingxenye eyinhloko noma ukucaciswa okufana nokugudluzwa, ikhamera, ipheshana lokungeniswa noma igumbi lomlilo kushintshwa, injini ingase idinge idizayini yepayipi ehlukile futhi kufanele ibuyiswe ukuze isebenze kahle kakhulu.
