Umhlahlandlela Ophelele we-BMW N52 Engine Tuning

Injini ye-N52 isalokhu iyikhethelo eliphezulu kubathandi bezimoto ngenxa yetorque yayo engenamthungo kanye nokusebenza okuthembekile. Iningi labanikazi bezinjini ze-BMW N52 bahlose ukusunduza ukusebenza kwayo ngaphezu kwamandla ayo ahlaba umxhwele.

Abanikazi bezimoto abafisa ukukhushulwa kancane kwamandla ehhashi noma ingoma ye-N52 yangokwezifiso ebanzi bangathola izinketho eziningi zokusiza ukufinyelela imigomo yabo yokusebenza. Le ndatshana izodingida izindlela zokushuna eziningi zenjini ye-N52 kanye nezingxenye ezidingekayo, izidingo zesoftware, nezithuthukisi zokusebenza ezilindelekile.

Ukuqonda injini ye-N52 namandla ayo

Kusukela ngo-2004 kuya ku-2015 iBMW yasebenzisa i-aspirated yemvelo i-inline-6 ​​N52 injini kuzo zonke izinhlobo zayo ze-E90 3 Series, E60 5 Series, Z4, X3, kanye ne-X5. I-BMW inikeze le njini ngezinguqulo eziningi enamandla aphumayo alungiselwe amamodeli nezimakethe ezahlukene.

• I-N52B25 (2.5L)

174 hp (130 kW) / 170 lb-ft (230 Nm)

215 hp (160 kW) / 184 lb-ft (250 Nm)

• I-N52B30 (3.0L)

215 hp (160 kW) / 200 lb-ft (270 Nm)

228 hp (170 kW) / 221 lb-ft (300 Nm)

255 hp (190 kW) / 220 lb-ft (300 Nm)

268 hp (200 kW) / 232 lb-ft (315 Nm)

Injini ejwayele ukushiselwa i-N52 inamandla okushuna uma iqhathaniswa nezinjini ze-turbocharged zakwa-BMW, ​​njenge-N54 noma i-B58. Naphezu kwemikhawulo, okunye ukuthuthukiswa kungasiza ukuletha ukuthuthukiswa okukhulu.

Izinketho zokushuna zeBMW N52

1. Indawo yokuqala: ukushuna kwesitoko kanye nokuthuthukiswa okuyisisekelo

Kubalulekile ukuqonda indawo yokuqala ngaphambi kokuhlola amasu okushuna athuthukile. Ishuni yasembonini yenjini ye-N52 ihlose ukuzuza ibhalansi phakathi kokuphehlwa kukagesi, ukonga kukaphethiloli, namazinga okukhishwa kwegesi. Injini iletha amandla aphumayo angashintshi kodwa isavulekele ukuthuthukiswa.

Abathandi bezimoto abaningi baqale bacabange ukushintsha indlela abayithathayo ngayo njengenketho yabo yokuqala yokulungisa. Ubuningi bokudla kwesitoko bungakwazi ukubhekana nezimo ezihlukahlukene kodwa bukhawulela amathuba okuthuthukisa ukusebenza. Ukufaka a ukuthathwa kwesiteji okuhlukahlukene kusuka ku-Active Autowerke idala ukuthuthuka okukhulu kwamandla ehhashi nokusebenza kwetorque. Iningi labanikazi liyayibona le modi yenjini ye-n52 njengenye yezinketho zabo eziphezulu.

Okunye ukuthuthukiswa okudumile yi-exhaust system. Ukushintshwa kwesistimu ye-exhaust esebenza kahle kakhulu kuholela ekusebenzeni okungcono kwenjini futhi kudala inothi lokukhipha elinolaka. Izihloko ziletha izithuthukisi zamandla ezibalulekile futhi zisebenza kahle nakakhulu uma zibhangqwe nezinguqulo ezengeziwe.

2. Ukushuna okuthuthukile: isofthiwe nokuguqulwa kwe-ECU

Uma ukulungiswa kwebhawodi sekuqediwe, abanikazi bangaqala ukuhlola izinketho zokushuna ezithuthukisiwe ukuze bathuthuke. Iyunithi yokulawula injini (ECU) isebenza njengobuchopho bemoto, futhi ukuguqulwa kwesofthiwe kungavula ukukhuphuka kwamandla okuphakathi kuka-10 nangu-15 wamahhashi.

Isoftware yeFlash iphakathi kwezindlela ezithandwayo zokulungisa ukusebenza kwenjini ye-N52. Izifaki zingalayisha amafayela amasha okulinganisa ku-BMW ECU ngokusebenzisa le nqubo, ezivumela ukuthi zilungise isikhathi sokubasa kanye nokulethwa kukaphethiloli eceleni kwamanye amapharamitha wesistimu. Ingoma ye-StageFP igqama njengenketho edumile eletha isisombululo somuntu siqu sokuhlela esiklanyelwe imoto yakho kanye nezinguqulo zayo.

Isoftware ye-Flash idinga amathuluzi afanele ukuze isetshenziswe ngempumelelo. Isibonelo, ukutshala imali kukhebuli yekhwalithi efana ne-Kline Ikhebula le-OBDII imele ukukhetha okubalulekile ngoba izintambo ezishibhile zivame ukukhiqiza izinkinga zokushuna kwe-ECU. Inqubo ye-flash idinga ukuthi ibhethri yemoto ishajwe ngokugcwele noma ixhunywe eshajani ukuvimbela ukuphazamiseka.

3. Ukuphindaphinda kwesiteji kanye namanye amaphakheji okusebenza

Ukuzuza ukushuna okuthuthukisiwe kwe-N52 kudinga ukufakwa kwenqwaba yesiteji (isiteji se-IM). Ukushintshwa kwenqwaba yesitoko ngomklamo othuthukisiwe kuholela ekugelezeni komoya okuthuthukisiwe kanye nokuphuma kwamandla engeziwe. Isiteji se-Active Autowerke IM iletha ukuthuthukiswa okubalulekile okuzuzwa amandla angu-20 kuye kwangama-25 kanye nokuphendula okuthuthukisiwe kwe-throttle.

Ukusebenzisa kokubili a ukuthathwa kwesiteji okuhlukahlukene kanye nezingxenye zokusebenza ezengeziwe ezifana nezihloko nezinhlelo zokuqeda amandla ziletha imiphumela ephakeme kakhulu. I-Weistec Engineering, ngokwesibonelo, ihlinzeka ngezithuthukisi eziningi zokusebenza kwenjini ye-N52 ngephakheji yayo yokulungisa i-Weistec N52. Ukuze kuthuthukiswe ukusebenza kwenjini, iphakheji ifaka ingoma yangokwezifiso eduze nezibuyekezo zefayela lokulinganisa kanye nezingxenye zehadiwe ezihambisanayo.

Okunye okucatshangwayo

1. Imiphumela ye-Dyno nokusebenza komhlaba wangempela

Imiphumela ye-Dyno ime njengebhentshimakhi eqondile yokuhlola impumelelo yokushuna. Abanikazi bangahlola ukuthuthukiswa kokusebenza kwangempela kusukela ekuthuthukisweni kwabo ngokuhlolwa kwe-dyno, okubonisa amamethrikhi okusebenza anembile.

Khumbula ukuthi idatha evela ekuhlolweni kwe-dyno ingase ibonise imiphumela ehlukene ngenxa yezimo zemvelo, ezifana nomswakamo ophezulu noma ikhwalithi yamafutha, kanye nezici ezihlukile zokusethwa kwemoto yakho.

Ukuguqulwa kwenjini ku-N52 kungaphazamisa kakhulu amazinga okusetshenziswa kukaphethiloli. Ukushuna kungakhuphula ukuphuma kwamandla kodwa kungase kubangele ukusetshenziswa kukaphethiloli okuphezulu kubashayeli abanolaka. Abashayeli kufanele baqaphe ukusebenzisa kwabo uphethiloli futhi bashintshe nesitayela sabo sokushayela ngokusekelwe kule datha.

2. Ukucatshangelwa kwezomthetho kanye nemvelo

Ukuqonda imithetho yendawo kanye neziqondiso kuhlala kubalulekile ngaphambi kokuqala noma yiziphi izinguquko zemoto. I-California Air Resource Board (CARB) isebenzisa izindinganiso eziqinile zokulungiswa kwezimoto kulo lonke elase-California. Ukuthuthukiswa kwemoto okuthile, njengokuqondile amasistimu wokuqeda noma ukuphindaphinda, ukuntula ukuthobela i-CARB, evimbela ukusetshenziswa kwazo emigwaqweni yaseCalifornia.

Kubalulekile futhi ukuhlola ukuthi ukuguqulwa kuzoyithinta kanjani imvelo. Ukushunwa kwemoto kungathuthukisa ukusebenza kodwa kunamandla okunyusa amazinga okukhishwa kwegesi. Ngakho-ke, abathengi kufanele bakhethe izingxenye nezinhlelo zesofthiwe eziklanyelwe ukunciphisa umthelela wendawo futhi balandele ngokuqinile imiyalelo yomkhiqizi.

Imicabango yokugcina

Injini ye-BMW N52 ingaletha ukusebenza okungcono ngokushuna ngenkathi igcina ukusebenza kwayo okuthembekile. Ukukhethwa kwamaphakheji okusebenza afanelekile nokulungiswa kuba semqoka uma ukhetha phakathi kokushuna okujwayelekile nokushuna kwamandla aphezulu.

Abathengi kufanele babuyekeze imithetho yabo yasendaweni, izinqubomgomo zokukhishelwa ngaphandle bese bakhetha isifaki sabo ngaphambi kokuqhubeka nokushuna. I-BMW izogcina ukwethembeka kwayo ngesikhathi sokushayela emgwaqeni womphakathi lapho ihlanganiswa nezindlela ezifanele zokushuna ze-ECU kanye nokuthuthukiswa kwamabholithi eduze kwendlela yokuthuthukisa yamasu.
