Injini kaphethiloli yakwaBMW N43 - yayinedumela?

Injini enamasilinda amane ngokwemvelo yakhiqizwa yiBayerische Motoren Werke iminyaka engu-7. Iyunithi yayihlukaniswa ngomklamo olula, okuyinto, nokho, yayibiza kakhulu ukuyinakekela. Injini ye-N43 ithole i-rap embi ngebhadi, kodwa ingabe kunjalo? Kungakanani ukwehluleka okubangelwa umklamo ngokwawo, futhi kangakanani - umphumela wokunganaki kwabasebenzisi ngokwabo. Sizozama ukuphendula. Funda!

Injini ye-N43 - kungani ithathe indawo ye-N42, N46 ne-N45?

Injini ye-N43 yasungulwa ukuze ithathe indawo yezinjini ze-N42, N46 kanye ne-N45. Kumele kuqashelwe ukuthi iyunithi entsha ayizange isatshalaliswe emazweni lapho kwakusetshenziswa khona uphethiloli onesulfure ephezulu. Ngenxa yalesi sizathu, ukukhiqizwa kwe-N46 ne-N45 akukamiswa. Ingabe amayunithi okulinganisa ayehluke ngempela?

Inguqulo entsha ifakwe umjovo kaphethiloli oqondile. Ngo-2011, njengengxenye yokusetshenziswa kobuchwepheshe obusha ezinjinini ze-BMW, ​​iyunithi ye-N43 yathathelwa indawo inguqulo ye-turbocharged eyi-four-cylinder ye-N13. 

Yiziphi izinkinga zobuchwepheshe abasebenzisi benjini ye-N43 ababa nazo?

Phakathi kokuwohloka okushiwo kaningi okwenzeka ngesikhathi kusetshenziswa iyunithi, abanikazi bezimoto babonisile:

• ukuqhekeka kweziqondiso ze-plastic time chain;
• izinkinga zomjovo;
• ukungasebenzi kahle kweyunithi yekhoyili;
• ukulimala kwenzwa ye-NOx.

I-N43 design - yini okudingeka ukwazi?

Kufanelekile ukusho izici zeyunithi. Injini ye-N43 yayiphawuleka ngomklamo wayo, owawenziwa ngama-alloys alula. Ngaphezu kwalokho, abaklami banquma ukuyihlomisa ngobuchwepheshe bokuqalisa - ngenxa yalokhu, imoto enalolu phiko bekufanele ihambisane nemvelo. Konke lokhu kwahambisana nohlelo lokuvuselela amandla ngesikhathi sokubhuleka.

Inguqulo N43B16 - ulwazi olubalulekile

Iyunithi kule nguqulo bekuwukungena esikhundleni se-N42B18. Zombili bezisekelwe ku-N43B20, kodwa injini entsha ifakwe amasilinda amancane - 82 mm, i-N43B16 nayo ibe ne-crankshaft emfushane ene-stroke engu-75,7 mm. Ukushintshwa kwenjini nakho kwehlisiwe kwafinyelela ku-1,6 litres.

Ku-N43B16, ama-piston ayenesilinganiso esiphezulu sokucindezela (12). Ngesikhathi esifanayo, abaklami be-BMW banquma ukufaka umjovo oqondile, owawuhlanganisa ukususwa kwe-Valvetronic. Le nguqulo yenjini yayisetshenziselwa ikakhulukazi izinhlobo ze-BMW 16i. Ngakolunye uhlangothi, i-N43 yashintshwa ngo-13 yi-N16B2011 - yayiyi-1,6-litre four-cylinder turbocharged injini. 

Inguqulo ye-N43B16 - ukucaciswa kwedrayivu

Le njini iyinguqulo entsha engu-2 litre ye-N42B20 ekhiqizwe ngezinguqulo eziningi. Le njini ye-N43 isebenzisa i-ia direct fuel injection system kanye ne-Valvetronic variable variable valve lift system isusiwe.

Ukufakwa kwama-pistons amasha kwakufanele kukhuphule isilinganiso sokucindezela sibe ngu-12. Yonke into ihambisana nokusetshenziswa kweyunithi yokulawula ye-Siemens MSD 81.2. Injini ye-N43B16 yashintshwa ngo-2011 yiyunithi ye-turbocharged ye-N13B16. 

Ukuqhekeka yizinkinga ezivame kakhulu ngenjini ye-N43

Kuzo zombili izinguqulo zokuqala nezesibili zenjini ye-N43, enye yezinkinga ezivame kakhulu eziphakamayo ukudlidliza kweyunithi. Uma ukungasebenzi okunjalo kwenzeka, ama-injection azodinga ukushintshwa. Abashayeli bezimoto abanalolu phiko bangase bakhononde ngokungalingani kwenjini. Imbangela ngokuvamile kuba amakhoyili okuthungela anephutha. Kulokhu, kuzoba usizo futhi ukufaka esikhundleni sezingxenye ezindala ngezintsha.

Ungazivikela kanjani ezinkingeni ngale njini?

Kuyenzeka futhi ukuthi ipompo ye-vacuum iyavuza. Lokhu kuvame ukwenzeka ngemva kokugijima amakhilomitha angu-60 kuya kwangu-000. Isixazululo esisebenzayo ukushintshwa kwezingxenye. Uma usebenzisa izimoto ezinenjini ye-N43, kubalulekile ukuhlola njalo isimo sesistimu yokupholisa. Lokhu kuyivimbela ekushiseni ngokweqile.

Noma ngubani onemoto enalolu phiko kufanele anakekele izinga lamafutha enjini asetshenziswayo. Lokhu kubalulekile ngoba izinga lokushisa lokusebenza kweyunithi ngokuvamile liphakeme ngokwanele ukuthi ukusetshenziswa kukawoyela wezinga eliphansi kungaholela ekulimaleni okukhulu. 

Injini ye-N43 ingabangela izinkinga kubashayeli abaningi, kodwa ngokusebenza kahle, ungasebenzisa injini ngaphandle kokulungiswa okubizayo okwenziwa umakhenikha. Kuyadingeka ukusevisa iyunithi njalo futhi usebenzise uwoyela omuhle wenjini. Ngokulungiswa okufanele kanye nokushintshwa ngezikhathi ezithile kwezingxenye ezibalulekile, imoto enenjini ye-N43 izosebenzela umnikazi wayo futhi igweme izinkinga ezinkulu.
