Izingozi zokucindezela komjovo ophansi

Ulwazi lomuntu siqu lokukhuluma ngezingozi zokucindezela komjovo ophansi. NgoMeyi wonyaka odlule, endaweni yokwakhiwa kweGuan 18-21 kahle, umqhubi wabika intuthu emnyama evela enjinini, ukwanda kokusetshenziswa kukaphethiloli, kanye nokukhuphuka kwezinga likawoyela wokugcoba ku-crankcase. Isizathu singase sibe ukucindezela okuphansi komjovo, ngakho ngilethe isethi yama-injection. Uwoyela kanye namalitha angu-30 kawoyela wenjini bafike endaweni yesigameko. Lapho isilinda sinqanyulwa, kwatholakala ukuthi isilinda esingu-1,356 sasingasebenzi kahle. Ngemva kokuhlakaza ama-injection enjini angu-6, kwatholakala ukuthi amasilinda angu-1, 3, no-56 ayevuza uwoyela ngamazinga ahlukahlukene, futhi angu-136 ayebonakala ngokukhethekile. , Ngemva kokuhlakazwa, ibhantshi lamanzi le-three-cylinder fuel injector ligcwele amafutha edizili. Ingcindezi yokulinganisa yaleli qembu lama-injection ingaphakathi kuka-140+10kgf/cm. Kuyabonakala ukuthi izimpawu ezingenhla zibangelwa ukucindezela komjovo womjovo uphansi kakhulu, i-atomization kaphethiloli impofu, izinhlayiya zenkungu kawoyela ziba mkhulu, futhi uwoyela uyaconsa noma ugeleze. , imibhangqwana yesijovo sikaphethiloli eyisilinda eyodwa noma enamasilinda amaningi iconsa uwoyela omningi, futhi uphethiloli owuketshezi uvuza ku-crankcase ngokusebenzisa indawo eseceleni ye-cylinder liner neringi yepiston, okubangela ukuthi izinga likawoyela likhuphuke noma ligcwale ngesikhathi sokuhlolwa okuvamile. kanye namandla. umbusi. Ngasikhathi sinye, umfutho womjovo kaphethiloli uphansi kakhulu, okuholela kuphethiloli ongekho kahle we-athomu, ububanzi obufushanisiwe futhi awukwazi ukungena kulo lonke igumbi elivuthayo, okuholela ekuhlanganiseni kabi kukaphethiloli nomoya kusilinda, okuholela kuntuthu omnyama ophuma ekukhishweni kwegesi. injini ye-diesel, ukwanda kwe-carbon deposits ku-cylinder, nobunzima ekuqaliseni injini.
