BMW N42B20 injini

Injini dze-in-line dzeimwe yeanogadzira mota hombe pasirese, BMW, haisiriyo chete quintessence yekuvandudza uye engineering audacity, asiwo mutakuri wenhoroondo refu.

Uchishandisa muenzaniso weinjini yakavakirwa paN42B20 cylinder block, unogona kunyatsotevera izvo nuances mainjiniya eBavaria akateera pakugadzira injini.

tsananguro

Kana iwe ukango pfuura nenhoroondo yeinjini dzeBMW, tinogona kugumisa kuti mainjiniya eBavaria anonyatso kukudza tsika dzavo, uye mhinduro dzavo itsva dzinobva pakutsvaga kwekukwana. Iwe unoti mota yakanaka mumativi ese haigone kuvapo? Chete kwete kune pfungwa dzekubvunza dzevanjiniya veGerman, nekuti ivo havana kubvumirana nechirevo ichi, nguva imwe neimwe vachityora stereotypes pamusoro pesimba rakaderera pamainjini madiki.

Nekudaro, zvakakosha kucherechedza kuti hunyanzvi hweinjiniya uye tekinoroji hadzina kugara kwenguva yakareba, nekuti pakati pe-90s - kutanga kwema2000, nguva yekushambadzira yakawedzera kukurira maindasitiri akasiyana, uye mota inenge yekutanga.

Aya ndiwo maratidziro akaita injini "guzzling" mafuta mumarita, silinda zvidhinha izvo zvinotadza chete nekuda kwekupisa zvishoma uye mamwe "matekinoroji" anosiririsa anosemesa kune vazhinji vane ruzivo varidzi vemotokari uye makanika emasevhisi emotokari.

Zvisinei, iyo yekupedzisira, iyi yemhando ye "tricks" yetekinoroji haisi kunyanya kunetseka, kana kwete kutaura zvinopesana.

Ngatirege kutaura pamusoro pezvinhu zvinosuwisa, ngatitarisei kurongeka kwekufamba kwenguva kwekugadzira injini dzeBMW dzepakati (nemusika zviyero) vhoriyamu, kureva, 2.0 malita. Yakanga iri vhoriyamu iyi, pamwe chete nehunyanzvi huripo, iyo mainjiniya eBavaria akafunga kuti inenge yakanaka maererano nezvose (!) Hunhu hunodiwa kubva mairi: simba, torque, uremu, kushandiswa kwemafuta, uye hupenyu hwebasa. Ichokwadi, mainjiniya haana kuuya kuvhoriyamu iyi pakarepo, asi zvese zvakatanga neinjini ine M10 index, iri pamwe naye iyo iyo nhoroondo yakakura-yakakura yemutsara mana-cylinder zvikamu zveBMW brand inotanga.

Ndinofanira kubvuma kuti panguva iyoyo, BMW yakagadzira, kana isiri injini yakanaka, saka zvechokwadi imwe yeakanakisa munhoroondo yekambani. Yakanga iri iyo M10 block iyo yakashanda seimwe nzvimbo yehuwandu hukuru hweinjiniya mhinduro, iyo iyo kambani yakazotanga kuunza muzvikamu zvayo zvitsva. Paive nenhamba huru yekusiyana kwehunyanzvi hwemotor kubva paM10 block, pakati pavo:

• kuyedza nehuwandu hweinjini dzinopisa mukati;
• miedzo ne cylinder head;
• akasiyana mafuta ekupa masisitimu (1 carburetor, mapatya carburetors, mechanical jekiseni).

Mune ramangwana, iyo M10 block yakatanga kupedzwa, matekinoroji matsva "akamhanyisa", pakupedzisira, akawanda einjini akabudiswa, ayo akavakirwa pa "ngano" M10. Paive nemhinduro dzakawanda dzetekinoroji panguva iyoyo, kubva kune masisitimu ekupa mafuta kusvika pakuyedzwa nemisoro yemasilinda (maviri-shaft cylinder misoro) uye kugoverwa kwehuremu hweinjini nemuchina zvakazara. Iyo tekinoroji runyorwa rwemotor, iyo yaive yakavakirwa paM10 zvakanyanya, tinopa runyoro rupfupi maererano nekukura kwekufamba kwenguva:

• M115/M116;
• M10B15/M10B16;
• M117/M118;
• M42, M43;
• M15 - M19, M22/23, M31;
• M64, M75 - ekunze shanduro dzeinjini dzeUS (M64) uye Japan (M75) misika.

Mune ramangwana, pamwe nekumwe kusikwa kwemamotor, mainjiniya eBavaria akasvika pakugumisa kuti iyo yakanyanya kufunga uye tekinoroji yakakwira M10 mota ichava mutsivi wemotor kubva kuBC (cylinder block) M40. Uye saka injini dzakazotevera dzakaonekwa, pakati pavo paiva neM43 uye N42B20, iyo yainyanya kukosha kwatiri.

Ruzivo rwese uye tekinoroji maitiro eiyo mukati combustion injini BMW N42B20

Masimba emagetsi akavakirwa paN42B20 block akagadzirwa maererano ne "canons" yemazuva ano ekuvaka injini. Prototype mota pane iyi block yakavimbisa kubwinya kwakareba kwechikamu ichi, asi zvese hazvina kushanda sezvaitarisirwa. Yakatangira N42 yaive mota ine M43 index, iyo "yakatora" matekinoroji ese akanakisa akaedzwa pa-in-line mana:

• kushanda kwemavharuvhu nenzira ye roller pushers;
• timing chain mechanism;
• kuwedzera kuoma uye kuderera kwehuremu hwe cylinder block;
• anti-knock kugadzirisa (nekushanda kwakasiyana kune imwe neimwe silinda);
• tekinoroji yakagadziridzwa pistons (ine cutout mune siketi).

Kusiyana kweinjini paN42 block, kuruboshwe - N42B18 (vhoriyamu - 1.8 l), kurudyi - N42B20 (vhoriyamu - 2.0 l).

Zvichakadaro, mumwe wemisiyano mikuru pakati peinjini dzeN42B20 uye kumwe kusiyanisa paN42 block yaive kutaridzika kweaviri-shaft cylinder musoro pamwe chete neakasimba nguva yevharuvhu (nekuda kweiyo VANOS system) uye yeValvetronic variable valve lift system. Kushandiswa kwezvirongwa izvi zvose uye matekinoroji kwakaita kuti zvibvirire kuderedza kushandiswa kwemafuta uye kubvisa simba rakawanda (zvichienzaniswa neshanduro dzakapfuura) kubva mujini, asi, zvinosuruvarisa, hazvina kuwedzera kuvimbika.

Kana pane kudikanwa kwekuziva iyo chaiyo yekumaka yeinjini uye nhamba yekuzivikanwa kwayo, saka iwe unofanirwa kuvimba nedhayagiramu iri pazasi.

Kazhinji, injini haigoni kuzvirumbidza pamusoro pekuita kwakakosha, kunyanya kana ichienzaniswa nezvizvarwa zvekare zvemotor. Sezvinogona kuonekwa, kusiyana kukuru ndiko kuderedza kushandiswa kwemafuta uye kuwedzera kuduku kwesimba. Zvinosuruvarisa chete, iwe unogona kuona kuwedzera kwesimba kwakakura chete nekumhanya kwakanyanya, uye kunyangwe musanganiswa neotomatiki kutapurirana, unogona kukanganwa nezve simba uye nekukurumidza mijaho.

Maronda chaiwo ICE BMW N42B20

Injini dzakavakirwa paN42 block dzakava dzinenge dzakanyanya tekinoroji dzemukati dzinopisa injini dzenguva iyoyo. Kusiyana nevakatangira, maBavarian vakasarudza kuomesa dhizaini nekuwedzera 2 camshafts kumusoro wecylinder, uye iyo Double-VANOS system yakawedzerwa kwavari. Muchokwadi, kugadzirwa kwese kwakaunza mukurumbira kune mota idzi, kunyangwe zvisiri izvo izvo zvakarotwa nevagadziri vemota idzi.

Macamshaft maviri akakura, hongu, asi yakakura seti yakaoma yehunyanzvi mhinduro, seDouble-VANOS, inova chigumbuso. Zvose izvi zvine maitiro akanaka pakushanda kwemazuva ose, nokuti kushandiswa kwemafuta kunoderedzwa, asi pane pfungwa mune izvi here? Kunyanya munyaya iyo motokari dzinoshandiswa munyika dzeRussian Federation neCIS, uko kunaka kwemafuta nemafuta kunosiya zvakawanda zvinoda kudiwa. Zvinova pachena kune muverengi anokurumidza-witted kuti kushandiswa kwemafuta emhando yakaderera uye mafuta emafuta ane mhedzisiro yakaipa kwazvo pamanode emota. Kunyangwe iyo yekufungidzira hupfumi hwemafuta yakakosha kugadziriswa kunodhura kweinjini yekupisa kwemukati - rega munhu wese azvipindure.

Isu, zvichibva pane data data, tichaona mamwe nuances maererano nekuchengetedza kwemota idzi, asi ngatitorei zvakarongeka, nekuti usati wataura nezvekugadzirisa, unofanirwa kuziva izvo zvinowanzoputsika mumamotor aya. Uye pano zvinhu zvose zvatove zvakanyanya kuoma, nokuti dambudziko guru reinjini idzi ndiro kupisa kwavo uye kusimba kwakasimba kwemafuta.

BMW mainjiniya anogadzika bhawa yakakwira yekudzora tembiricha yejinjini - pamusoro pe110 madhigirii, semhedzisiro - kupisa mafuta mu crankcase kusvika 120-130 madhigirii, uye kana iwe ukafungawo nezve diki rekuzadza vhoriyamu, ipapo zvese zvinoshanduka kuve zvakanyanya. regrettable.

Mafuta anopisa makoki uye anovhara nzira dzemafuta, nekufamba kwenguva, iyo Valvetronic system drive inotanga "kurumwa", uye iyo Double-VANOS system actuators inotadza.

Nekuda kweizvozvo, injini inowana yakakosha coking, inomira kufema, uye kana iwe uchifunga kuti matekinoroji ari pamusoro anoitwa pane aruminiyamu cylinder block uye cylinder musoro, nyora zvakaraswa. Vazhinji varidzi veBMW vanoziva pachavo nezve "yakayangarara" silinda misoro nekuda kwekupisa, "matekinoroji" akadaro anodiwa here? Zvinogoneka kuti mumamiriro eEurope, nekudziya kwakadzikira, kushomeka kwemotokari dzemotokari uye mafuta emhando yepamusoro, matekinoroji aya aizozviratidza zvakakwana. Asi mumamiriro ezvinhu akaoma eRussia - zvechokwadi kwete.

Kana iwe ukasabata pane yakakomba uye isingaperi dambudziko reN42B20 / N42B18 mota dzine chekuita nekupisa, asi inokanganisa zvimwe zvese zveinjini, saka hapana hunhu husina simba, kunze kwekunge zvichida:

• nguva cheni tensioner (resource ~ 90 - 000 km);
• kukundikana kazhinji kweBREMI mhando yekubatidza coils (inogadziriswa nekutsiva makoiri neEPA);
• "zhor" oiri nekuda kwekutyoka kwevhavha stem seals (kazhinji kuchinja kwemafuta kunodiwa uye kupisa kweinjini yekupisa kwemukati hakugamuchirwe).

Shandura uye kugadzirisa ICE BMW N42B20

Iyo N42B20 mota haigone kunzi inochengetedzwa uye iri nyore kuchengetedza, zvisinei, nekushanda kwakaringana, neanogara achichinja oiri (kamwe chete 4000 km) uye kusavapo kwekupisa, inogona kugara kwenguva refu. Uye kunyange kana "capital" ichidiwa neimwe nguva, iri kure nechokwadi chokuti motokari yemazuva ano inofanira kukandwa kunze.

Mukushaikwa kwekupisa uye "kurarama" silinda misoro, kugadziridza hakuzove kwemuchadenga, asi kunotoda mari. Mamiriro ezvinhu zvakare akarerutswa nenhamba huru yezvisiri zvepakutanga zvakafanana zvakasara pamutengo wakaderera, izvo zvinogona kuwedzera hupenyu hwemota kune imwe nguva yenguva (zvichienderana nemhando yezvisara).

Kazhinji, varidzi veBMWs vane N42B20 / N42B18 injini vanoenda kune mhinduro yakadai sekuchinjanisa mota kune imwe. Kusada kushivirira kushaya simba kweinjini paN42 block kazhinji kunomanikidza varidzi vazhinji kutsiva yavo "yakaoma" ina nechimwe chinhu chine simba.

Kazhinji, imwe yeinjini huru yekuchinjisa panzvimbo yeN42B20 ndeinotevera injini dzemoto dzemukati (mumutsara matanhatu-cylinder):

• BMW M54B30;
• Toyota 2JZ-GTE.

Iwo mamotor ari pamusoro haana matambudziko akakomba seN42B20, ane simba rakawanda uye akavimbika, uye anokwenenzverwa nyore.
