D-243 - injini evivinywa ngesikhathi

Imoto eyaziwa kakhulu yaseBelarusian, yiqiniso, iyithrekhi ye-MTZ. Kodwa kuzo zonke izindawo ze-post-Soviet isikhala, imikhiqizo ye-Minsk imishini isetshenziswa kakhulu, okwenza isintu sibe yi-D-243 - injini ehlukaniswa ngamandla ayo, ukwethenjwa, ukungathobeki kanye nezwe jikelele.

Injini ye-diesel D-243

D-243 - injini, isitshalo samandla e-diesel esine-inline line-cylinders (injini inezinsimbi ezine ezilinganayo). Ukuze ulawule ijubane le-crankshaft, kusetshenziswe umlawuli we mechanical. Ukupholisa ngokuvamile kuyamanzi, ngaphandle kokuthuthukisa. Iningi lokuthandwa ngenxa yokungathobeki kwalo lithole injini D-243. I-injini iyakwazi ukusebenza ngokushisa okuphansi kwezinga eliphansi lokushisa okuphakathi kwe-+44 kuya ku-44 degrees Celsius.

Inhloso eyinhloko ye-powertrains - ukufakwa kwamatrakta ngeklasi eliphakeme le-14-20 kN. Ngokuvamile bahlome imishini yokulima noma yezimboni, kanye nemishini yamasimu.

Kodwa ngokuvamile ukwakheka kwemishini ekhethekile kakhulu (izitshalo zamandla ze-AD series, i-dizeli eqhuba i-PD kanye nokudonsa amayunithi) futhi ihlanganisa amayunithi e-D-243. Izinjini kumele zinikezwe ngesimo esifanayo - sebenzisa ensimini ene-air exchange engenamkhawulo.

Ukucaciswa kobuchwepheshe

I-D-243 iyinjini eyanconywa ukuthi ifakwe kwiTT-82 neTT-80 tractors, futhi kufanele ihlanganiswe ngezinye izakhi zamagesi kagesi, ukulawula izinzwa, ama-radiators amanzi. Kule ndaba kuphela kuphela okuqaphela injini ye-D-243, izici zazo ezinikezwe ngezansi, wonke amandla awo.

1. Indlela yokwenza ingxube i-fuel injection ngqo.
2. Inombolo yezilinda zokusebenza ezine, ilungiselelo lomugqa.
3. Umthamo we-cylinder ungama-4.75 amalitha.
4. Amandla okusebenza angama-59.6 kW.
5. I-torque esiphezulu yi-258 N * m.
6. I-compression ratio iyunithi engu-16.
7. Isisindo esigcwele esingu-430 kg.

Kulesi simo, i-crankshaft ingashintsha kuphela ngesivinini esingenalutho ngesilinganiso se-2380 rpm, ngoba sinqunyelwe umlawuli.

Izinkomba zokusebenza

Ngaphandle kwezici zobuchwepheshe, nezinkomba zokusebenza ziveza ukufakwa kwe-D-243. Injini ikhiqiza imininingwane elandelayo ngesikhathi sokusebenza:

• Ukusetshenziswa kwamagesi uma usebenzisa amandla angu-100% nangejubane lika-1500 rpm - 220 g / kW * h;
• Ukusetshenziswa kwamafutha enjini "okushisa" - 0.9 g / kW * h; Ngomthwalo wemali engu-100% - angabi ngaphezu kuka-0.2 amalitha ngehora;
• Uhlobo lwamafutha asetshenzisiwe - I-CI-4 ekilasini ngokwezigaba ze-АР'I noma E3-96, 4-99, 5-02 ngokusho kwe-AS'ЕА;
• Uhlobo lwe-antifreeze - epholile ukushisa ama-"TC-40" noma "TC-65".

Izinjini ziqaliswa noma isiqalo segesi noma isitshalo sokuqala sokuqala. Esikhathini esilandelayo, incwadi "L" ingeziwe egameni. Ngokuya ngenhloso yerektri, lapho i-motor efakwe khona, i-unit ingahlonyiswa ngemishini eyengeziwe - i-compressors ye-pneumatic, imihlangano ye- clutch disc nezinye izingxenye. Lokhu kufanele kucatshangelwe lapho kwenziwa isondlo, bese injini ye-D-243 ingadingi ukulungiswa.
