Injini Mitsubishi 4m40

Idizili entsha engu-4M40

Lena iyunithi yamandla edizili engu-4-cylinder ene-camshaft engaphezulu. I-4m40 ifakwe i-cast-iron cylinder block kanye nekhanda le-semi-aluminium cylinder. Umthamo wenjini 2835 cmXNUMX.

Incazelo yenjini

Noma yikuphi ukufakwa kwemoto kufanele kulinganiswe amandla angenayo. 4m40 injalo. 2 ama-balancer shaft engeziwe anesibopho salo msebenzi. Ashayelwa amagiya aphakathi asuka ku-crankshaft, futhi atholakala kanje: phezulu kwesokudla naphansi kwesokunxele. I-crankshaft yenjini iyinsimbi, isekelwe kuma-bearings angu-5. I-piston yohlobo olukhethekile, i-semi-aluminium, ixhunywe kwinduku yokuxhuma ngokusebenzisa iphini elintantayo.

Izindandatho zenziwe ngensimbi ekhonjiwe. Ama-Swirl combustion chamber (VCS) afakwe ekhanda lesilinda, okwenza kube nokwenzeka ukwandisa inkomba yokusebenza kahle kukaphethiloli. Eqinisweni, lawa ngamakamelo ensimbi avaliwe afakwe ekhanda le-cylinder. Ngaphakathi kukhona i-ceramic-metal insert kanye nesikrini esiyindilinga esakha igebe lomoya nengaphakathi lekamelo. Ngaphezu kokuqinisekisa ukuvutha okuphelele kukaphethiloli, i-VCS ivumela ukunciphisa inani lama-nitrogen oxide.

I-camshaft yenjini engu-4m40 kanye ne-high pressure fuel futha iphuma ku-crankshaft ngegiya.

Ukusebenza kanye nokugcinwa kwenjini ye-diesel

I-4m40 yaziwa kangcono ngenjini yePajero 2. Yaqala ukufakwa kule SUV ngo-1993. Uphiko lukadizili lwethulwa ukuze luthathe indawo ye-4d56 endala, kodwa lena yakamuva isakhiqizwa ngemuva kwalokho isikhathi eside.

Into yokuqala ukuthi ochwepheshe bezimoto ze-diesel banake i-turbine - insiza yayo ingu-4m40 esifundeni esingamakhilomitha ayizinkulungwane ezingu-300. Kanye ngonyaka, qiniseka ukuthi uhlanza i-valve ye-EGR. Ngokuvamile, i-motor inokwethenjelwa, ngokulungiswa okufanele njalo kanye nokufaka i-refueling ngophethiloli omuhle we-diesel namafutha, izohlala okungenani amakhilomitha ayizinkulungwane ezingu-350 wokugijima kwemoto.

Ukulungiswa kwe-valve ku-4m40

Ngemuva kwamakhilomitha ayizinkulungwane ezingu-15 enjini, kuyadingeka ukuhlola / ukulungisa ama-valve. Ukucaciswa kwenjini yomlilo yangaphakathi "eshisayo" kufanele kube kanje:

• ama-valve wokungena - 0,25 mm;
• kokuthweswa iziqu - 0,35 mm.

Kubaluleke kakhulu ukulungisa ama-valve ku-4m40, noma kunjalo, njengamanye ama-motor. I-Diesel 4m40 iyindlela eyinkimbinkimbi, efakwe izingxenye eziningi ezahlukene. Ukuze yonke into isebenze kahle isikhathi eside, kuyadingeka ukwenza ukugcinwa ngesikhathi.

Ukulungiswa kwe-valve 4m40

Amavalvu ngenye indlela "amapuleti" aneziqu ezinde. Wafake kusilinda block. Kunama-valve amabili isilinda. Uma ivaliwe, ihlezi phezu kwezihlalo ezenziwe ngensimbi eqinile. Ukuze izinto "zamapuleti" zingalimazi, ama-valve enziwe ngama-alloys akhethekile angakwazi ukumelana nemithwalo ebalulekile yemishini neyokushisa.

Amavalvu ayizingxenye ezibalulekile zesistimu yesikhathi. Ngokuvamile zihlukaniswa zibe i-inlet ne-outlet. Abokuqala banomthwalo wemfanelo wokungena kwengxube kaphethiloli, le yokugcina ngamagesi okukhipha umoya.

Enkambweni yokusebenza kwesikhathi eside kwenjini, "amapuleti" ayanda, futhi izinduku zawo zinde. Ngakho-ke, ubukhulu bezikhala phakathi kwamakhamera aphushayo neziphetho nazo ziyashintsha. Uma ukuchezuka kudlula amanani aphezulu avumelekile, kuzodingeka ukulungiswa okuphoqelekile.

Kubaluleke kakhulu ukwenza izinguquko ngesikhathi. Isibonelo, ngezikhala ezincane, "ukuvutha" kuzokwenzeka nakanjani - ukusebenza kwesistimu yokusabalalisa igesi kuzophazamiseka, ngoba ungqimba oluningi kakhulu lwe-soot luzoqoqwa ezibukweni "zamapuleti". Ngokukhuphuka kwezikhala, ama-valve ngeke akwazi ukuvuleka ngokugcwele. Ngenxa yalokhu, amandla enjini azoncishiswa kakhulu, ama-valve azoqala ukungqongqoza.

I-Timing chain drive: okuhle nokubi

Injini engu-4m40 isebenzisa uchungechunge lwesikhathi lwemigqa emibili. Ihlala isikhathi eside kakhulu kunebhande - cishe, cishe amakhilomitha ayizinkulungwane ezingu-250. Lesi yisixazululo esihlolwe isikhathi esizibonakalise sithembekile impela. I-chain drive ihlala isikhathi eside, nakuba inenani lokungalungi.

1. Izinga elikhulayo lomsindo wenjini engu-4m40 libangelwa ukusetshenziswa kwe-timing chain drive. Kodwa-ke, lokhu kungalungile kunxeshezelwa kalula nge-shvi eqhutshwa kahle yegumbi lenjini.
2. Ngemva kwamakhilomitha ayizinkulungwane ezingu-250, iketango liqala ukwelula, umsindo wesici uvela. Yiqiniso, lokhu akuthembisi izinkinga ezinkulu - ingxenye ayisheleli kumagiya, izigaba ze-GDS aziduki, injini iyaqhubeka nokusebenza ngokuzinzile.
3. Ama-metal chain motors anzima kakhulu kunama-motor aqhutshwa ngamabhande. Lokhu kuthinta kabi imisebenzi yokukhiqiza yesimanje. Njengoba wazi, emncintiswaneni wezimbangi, wonke umuntu ugxile ezinjini ezivuthayo zangaphakathi ezihlangene, ngakho-ke bazama ukunciphisa ubukhulu beyunithi yamandla nesisindo sayo. Iketango lemigqa ephindwe kabili alihlangabezani namazinga anjalo nganoma iyiphi indlela, ngaphandle kokuthi umugqa owodwa mncane, kodwa akuyona eyedizili enamandla engu-4m.
4. I-chain drive isebenzisa i-hydraulic tensioner, ezwela kakhulu kumfutho kawoyela. Uma "igxuma" nganoma yisiphi isizathu, amazinyo eketango azoqala ukushibilika njengokushayela ibhande elijwayelekile.

Valve isitimela chain

Kodwa i-chain drive, kanye nama-minus, inama-pluses amaningi.

1. Iketango liyingxenye yangaphakathi yenjini, futhi ayikhiphi njengebhande elihlukile. Lokhu kusho ukuthi ivikelwe ngendlela enokwethenjelwa ekungcoleni, othulini nasemanzini.
2. Ngenxa yokusebenzisa i-chain drive, kungenzeka ukusetha kangcono izigaba ze-GDS. Iketanga alikho ngaphansi kokwelula isikhathi eside (izinkulungwane ezingama-250-300 km), ngakho-ke, alinandaba nemithwalo ekhulayo enjini - injini ngeke ilahlekelwe amandla ayo okuqala ngesivinini esikhulayo kanye nesivinini esiphezulu.

I-HPFP 4m40

Injini engu-4m40 ekuqaleni yayisebenzisa iphampu yomjovo ewumshini. Iphampu isebenze ne-MHI turbine kanye ne-intercooler. Lena kwakuyinguqulo ye-4m40, ethuthukisa i-125 hp. ngo-4000 rpm.

Kakade ngo-May 1996, abaklami bethula ukusetshenziswa kwenjini ye-diesel nge-turbine ye-EFI. Inguqulo entsha ithuthukiswe i-140 hp. ngesivinini esifanayo, i-torque yanda, futhi konke lokhu kwafezwa ngokusebenzisa uhlobo olusha lwepompo lomjovo.

Iphampu ye-high pressure iyisici esibalulekile senjini ye-diesel. Idivayisi iyinkimbinkimbi, yakhelwe ukunikeza uphethiloli enjinini ngaphansi kwengcindezi enamandla. Uma kwenzeka ukungasebenzi kahle, ukulungiswa okuphoqelekile kochwepheshe noma ukulungiswa kwemishini ekhethekile kuyadingeka.

I-HPFP 4m40

Ezimweni eziningi, iphampu yomjovo wedizili engu-4m40 iyehluleka ngenxa yezinga eliphansi likaphethiloli kanye nowoyela. Uthuli, izinhlayiya eziqinile zokungcola, amanzi - uma ekhona kuphethiloli noma ku-lubricant, ingena empompini, bese ifaka isandla ekuwohlokeni kwamapheya abizayo e-plunger. Ukufakwa kokugcina kwenziwa kuphela ngemishini ene-micron tolerance.

Kulula ukunquma ukungasebenzi kahle kwephampu yomjovo:

• imibhobho esebenza ngokufafaza nokujova uphethiloli wedizili iyawohloka;
• ukusetshenziswa kukaphethiloli kuyanda;
• ukwanda kwentuthu yokukhipha;
• umsindo wenjini ye-diesel uyanda;
• amandla ayancipha;
• okunzima ukuqala.

Njengoba wazi, i-Pajero yesimanje, i-Delica ne-Pajero Sport, ifakwe i-4m40, ine-ECU - umjovo kaphethiloli ulawulwa yi-electronic system. Ukuze unqume ukungasebenzi kahle, kufanele uthinte isevisi yedizili, lapho kukhona imishini yokuhlola yochwepheshe. Phakathi nezinqubo zokuxilonga, kungenzeka ukuhlonza izinga lokugqoka, impilo eyinsalela yezingxenye ezisele zeyunithi yedizili, ukufana kokunikezwa kukaphethiloli, ukuzinza kwengcindezi, nokunye okuningi.

Amaphampu omjovo wemishini, afakwe ezinguqulweni zokuqala ze-4m40, awazange esakwazi ukunikeza ukunemba kwe-dosing edingekayo, njengoba onjiniyela baqhubeka beshintsha umklamo, bewuletha kumazinga amasha e-ECO. Izindinganiso zokukhishwa kwegesi zaqiniswa yonke indawo, futhi uhlobo oludala lwepompo elinomfutho omkhulu lwabonakala lungakhiqizi ngokwanele.

Kuzinhlelo ze-elekthronikhi, baqhamuke namaphampu amasha omjovo kaphethiloli ohlobo lokusabalalisa, alekelelwa ama-actuator alawulwayo. Bakwenza kwaba nokwenzeka ukulungisa indawo ye-dispenser kanye ne-automatic fuel injection advance valve.

I-4m40 izenzele yona njengeyunithi yamandla enamandla futhi ethembekile. Nokho, isikhathi asimile - i-3m4 entsha enevolumu yokusebenza engu-41 amalitha isivele ifakiwe ku-Pajero 3,2. Le njini ingumphumela weminyaka eminingi yokusebenza konjiniyela abahlonze futhi baqeda izindawo ezibuthakathaka ezinhle, kodwa eziphelelwe yisikhathi ze-4m40.
