Injini Mitsubishi 4a31

Injini kaphethiloli eyi-four-cylinder in-line 16-valve, 1,1 l (1094 cc). I-Mitsubishi 4A31 ikhiqizwa kusukela ngo-1999 kuze kube manje.

Kuthuthukiswe ngesisekelo esandulela 4A30 nge umthamo 660 cubic metres. cm, ifakwe enguqulweni yokuqala nge-carburetor, futhi enguqulweni yakamuva enesistimu yokunikezela uphethiloli womjovo.

Injini ye-Mitsubishi 4A31 itholakala ngezinguqulo ezimbili. Kolunye uhlobo lwenjini evuthayo yangaphakathi, kwasetshenziswa uhlelo olujwayelekile lwe-ECI lokujova uphethiloli olunamaphuzu amaningi, ngakolunye, uhlelo lwe-GDI (okuvumela injini ukuthi isebenzise ingxube ethambile kahle kakhulu). Eyakamuva inyuse ukusebenza kahle kwezimoto ebifakwe kuzo cishe ngo-15%.

Izici zokuqhathanisa zezinguquko ezimbili:

Umlando wendalo

I-Mitsubishi Motors idinga amandla angaphezu kuka-4A30, futhi ngesikhathi esifanayo injini yokonga ukuze ithathe "i-niche" phakathi kwe-Minica key-car ethandwayo (izimoto ezincane ezinezinjini ezifika ku-700 cc), kanye namayunithi amandla anevolumu engu-1,3 -1,5 .XNUMX l. Abaqambi benkampani banqume ukucwenga eyokuqala kulayini wezinjini ezine-cylinder, ukuyihlomisa ngohlelo lwe-GDI.

Umanduleli "amashumi amathathu nanye" - injini 4A30 ibekwe ukusakaza ngo-1993. Yafakwa emotweni yedolobha elincane iMitsubishi Minica, ebonisa izinga lokusetshenziswa elingu-1:30 (30 km ilitha likaphethiloli ngalinye). Inkomba yephesenti yokusebenza kahle okuphezulu yalungiswa ngempumelelo, ngenkathi ikhulisa ivolumu namandla enjini, futhi ishiya ukwakheka kwangaphambilini kweyunithi.

Izinguquko zokuklama zithinte umthamo we-cylinder, ububanzi besilinda (kusuka ku-60 kuya ku-6,6), indawo yama-valve nama-injection. Isilinganiso sokucindezela sinyusiwe sisuka ku-9:1 saya ku-9,5:1 kanye no-11,0:1.

Izici

Isilinganiso sempilo yesevisi yeyunithi yamandla we-4A31 ngaphambi kokushintshwa cishe imakhilomitha angama-300 wokugijima kwemoto. I-motor ifakwe ama-valve angu-000 isilinda ngasinye, ishayelwa yi-camshaft eyodwa evamile engaphezulu. I-cylinder block yenziwe ngensimbi ekhonjiwe. Izindlu zepompo epholile kanye nekhanda lesilinda zenziwe nge-aluminium alloy. I-motor iwuketshezi olupholile.

Izici ze-KSHG, CPG:

• Ukulandelana kwesilinda: 1–3–2–4.
• I-valve impahla: insimbi.
• Impahla ye-piston: i-aluminium.
• Isihlalo sePiston: esintantayo.
• Iringithoni: insimbi eyinsimbi.
• Inombolo yezindandatho: 3 (izisebenzi ezi-2, i-scraper yamafutha engu-1).
• I-Crankshaft: ama-bearing angu-5.
• I-Camshaft: i-cast 5.
• Isikhathi sokushayela: ibhande elinamazinyo.

Inani elilinganiselwe le-clearance ku-valve drive:

Enjinini efudumele
ama-valve wokungena	0,25 mm
ama-valve wokukhipha	0,30 mm
Enjinini ebandayo
ama-valve wokungena	0,14 mm
ama-valve wokukhipha	0,20 mm
I-Torque	9 +- 11 N m

Umthamo kawoyela injini 4A31 injini 3,5 amalitha. Kulezi: ku-oyela sump - 3,3 amalitha; kusihlungi 0,2 l. Original Mitsubishi oil 10W30 (SAE) kanye SJ (API). Kuvunyelwe ukugcwalisa i-motor ene-mileage ephezulu ene-analogue ene-viscosity index ye-173 (Texaco, Castrol, ZIC, njll.). Ukusetshenziswa kwamafutha okwenziwa kuvimbela "ukuguga" okusheshayo kwezinto zezimpawu ze-valve stem. Ukusetshenziswa koketshezi lokugcoba okuvunyelwe umenzi akukho ngaphezu kwe-1 ilitha nge-1000 km.

isithunzi

I-Mitsubishi 4A31 motor iyiyunithi yamandla ethembekile futhi ehlala isikhathi eside enokugcinwa okuphezulu. Ngokuya ngokuvama kokugcinwa, ukushintshwa okufika ngesikhathi kwebhande lokushayela kanye nebhande lesikhathi, ukusetshenziswa kwamafutha aphezulu kanye nophethiloli, insiza yayo esebenzayo (ngokusho kokubuyekezwa) izoba ngu-280 km noma ngaphezulu.

Izindawo ezibuthakathaka

Uma sibheka ukubuyekezwa kwabanikazi, kunesici esithile senkinga yePajero Junior "abadala" - ukwanda kokusetshenziswa kukaphethiloli. I-exhaust iqhekeka ngokuphindaphindiwe kusukela ekudlidlizeni futhi inzwa ye-oxygen isetha imingcele engalungile yesistimu yokulawula uphethiloli.

Amaphutha ajwayelekile:

• Ukuthambekela kokwenyusa ukusetshenziswa kukawoyela ngemuva kophawu lwe-100 km. Ukulahlekelwa ngokuvamile kufinyelela ku-000-2000 ml nge-3000 km.
• Ukwehluleka njalo kwe-lambda probe.
• Ukuthambekela kokuthi amasongo e-piston aqambe amanga (kuncike kwikhwalithi kaphethiloli kanye nezindlela zokusebenza ezikhethwayo - isivinini esikhulu noma esiphansi).

Isisetshenziswa sebhande lesikhathi se-4A31 esimenyezelwe umenzi ngaphambi kokushintshwa sisuka ku-120 kuya ku-150 km ayizinkulungwane (ochwepheshe batusa ukuqapha isimo saso njalo, kusukela ekugijimeni kuka-80 km, futhi ukushintshwa uma kuvela imihuzuko ebalulekile). Ukushintsha ibhande lesikhathi kuyatuswa uma ushintsha injini ye-Mitsubishi 000A4 engalungile ngenkontileka, kungakhathaliseki ukuthi ingakanani ibanga layo.

Izimoto zifakwe injini ye-Mitsubishi 4a31

Zonke izimoto lapho injini ye-Mitsubishi 4A31 ifakwe khona zakhiwe ngesisekelo sesizukulwane sesi-6 semodeli ye-Mitsubishi Minica (E22A) ka-1989. Imoto yayinenjini engu-40-horsepower 0,7-litre. Abalandela iMitsubishi Minik bashayela kwesokudla, ekuqaleni okuhloswe ngaso emakethe yaseJapan.

UMitsubishi Pajero Junior

I-Mitsubishi Pajero Junior (H57A) 1995-1998 I-SUV edumile edonsa ngawo wonke amasondo - eyesithathu ngemuva kweMini emndenini wakwaPajero. Ikhiqizwa ngamazinga amabili okunquma: i-ZR-1 inesabelomali esiningi, kanti i-ZR-2 ifakwe ikhiye emaphakathi, isiteringi samandla kanye nokuhlobisa izinkuni. Kuqedwe ngo-3-st. Ukudlulisa okuzenzakalelayo, 5-st. transmission manual. Inguqulo ye-manual transmission isithandwa kakhulu phakathi kwabathandi be-off-road.

I-Mitsubishi Pistachio

Mitsubishi Pistachio (H44A) 1999 Igama lihunyushwa ngokuthi "pistachio". I-Economical front-wheel drive enezicabha ezintathu hatchback. Izinguquko zesakhiwo zathinta umzimba ongaphambili - ukuwuhlanganisa neqembu losayizi wesihlanu, kanye nokudluliselwa - imishini engu-5-speed. transmission manual. Imodeli yokuhlola, ekhiqizwa ngamakhophi angu-50 kuphela, ayizange ingene kunethiwekhi yokudayisa, kodwa yangena enkonzweni yezinhlangano zikahulumeni.

Mitsubishi Town Box Wide

I-Mitsubishi TB Wide (U56W, U66W) 1999–2011 Iminivan enezicabha ezinhlanu wonke amasondo anama-4-speed. Ukudlulisa okuzenzakalelayo noma i-5-st. Ukudluliselwa okwenziwa ngesandla kwemakethe yasekhaya yaseJapan. Ngo-2007, yathengiswa ngaphansi kohlobo lweNissan (Clipper Rio). Iphinde ikhiqizwe ngaphansi kwelayisensi e-Malaysia ngaphansi kwegama lomkhiqizo i-Proton Juara.

I-Mitsubishi Toppo BJ Wide

I-wheel drive yangaphambili noma i-4WD yesikhathi esigcwele, iveni elincane elino-4 tbsp. ukudluliswa okuzenzakalelayo. Ukuguqulwa kwe-Mitsubishi Toppo BJ, ehlukile kuyo, ngaphandle kwenjini, ngenani elikhulayo lezihlalo ku-cabin (5) kanye nesethi ephelele.

Ukushintsha injini

I-Mitsubishi 4А31 isetshenziswa njengomnikeli we-SWAP ukuze ifakwe ku-Mitsubishi Pajero Mini, esikhundleni seyunithi yayo engu-660-cc engasasebenzi. Ukushintshwa kwenziwa kanye ne-multifold exhaust, i-wiring kanye neyunithi yokulawula ye-elekthronikhi. Inombolo yenjini enamadijithi ayisithupha (izinhlamvu ezi-2 namadijithi angu-4) iphrintwa endizeni ye-crankcase engu-10 cm ngaphansi kwe-exhaust eningi.
