Ukujongana neengxaki eziqhelekileyo kunye nezilayishi (36-40)

36. Xa i-oyile ixutywa namanzi, i-oyile ye-injini iba mhlophe

Unobangela wengxaki:Amacandelo angonelanga oxinzelelo lokuvaleka kwamanzi anokubangela ukuvuza kwamanzi okanye ukuvaleka kwamanzi. I-cylinder head gasket yonakaliswe okanye intloko ye-cylinder iqhekekile, umzimba unemingxuma, kwaye i-oyile epholileyo iyaqhekeka okanye i-welded.
Iindlela zokusombulula ingxaki:buyisela ibloko lamanzi, buyisela igasket yentloko yesilinda okanye intloko yesilinda, buyisela umzimba, khangela kwaye ulungise okanye utshintshe isipholile se-oyile.

37. Idizili exutywe ne-oyile ye-injini yonyusa amanqanaba e-oyile ye-injini

Unobangela wengxaki:I-injector ye-fuel ye-cylinder ethile yonakalisiwe, i-valve yenaliti ibambekile, intloko yeoli eqhekekileyo iyatshiswa, njl.
Iindlela zokusombulula ingxaki:Jonga, lungisa okanye utshintshe isipholile se-oyile, jonga isirinji yokulinganisa okanye uyitshintshe, buyisela okanye lungisa impompo ye-oyile enoxinzelelo oluphezulu, buyisela impompo yeoli.

38. I-injini ikhupha umsi omnyama, owanda njengoko isantya se-injini sinyuka.

Izizathu zale ngxaki:Inaliti yepetroli engalinganiyo kakhulu okanye iatomization engalunganga, uxinzelelo lwesilinda olungonelanga, ukutsha okunganelanga, i-oyile ingena kwigumbi lokutsha, kunye nomgangatho ophantsi wedizili.
Indlela yokulungisa ingxaki:Coca into yokucoca umoya ukuqinisekisa inqanaba elichanekileyo lokuhanjiswa komoya, isantya esiphezulu sokutofa i-oyile yempompo yokubonelela nge-engile, i-piston ring cylinder liner inxitywe kakhulu. Ukuba i-valve ayivalwanga ngokuqinileyo, i-injector kufuneka itshintshwe. Khangela isahluli samanzi e-oyile kunye ne-turbocharger ukuvaleka okanye umonakalo; kufuneka zitshintshwe. Buyisela isibaso sedizili ngenye ehambelana neleyibhile, kwaye kufuneka uyenze ngokuchanekileyo. Umzekelo, ukuba ubetha i-accelerator, umsi omnyama uya kuvela.

39. Umlayishi we-ZL50C ukwimeko yokungenzi nto, kwaye isantya sokunciphisa kunye nokuphakamisa i-boom siyacotha.

Isiganeko esikhaphayo:Xa usebenza ixesha elide, inkqubo ye-hydraulic esebenzayo ivelisa ubushushu obuninzi.
Unobangela wengxaki:Uxinzelelo lokumisela ivalve yempompo yokulingwa luphantsi; i-spool yokulingwa kwempompo yokukhulula ivalve ixingile okanye intwasahlobo yaphukile; ukusebenza kwempompo yokulinga kuncitshisiwe. ;
Indlela yokulungisa ingxaki:Ukusetha kwakhona uxinzelelo kwixabiso lokulinganisa le-2.5 MPa; buyisela ivalve yokunceda impompo yokulinga; buyisela impompo yokulinga
Uhlalutyo lokusilela:Isizathu esithe ngqo sokunciphisa ukunyusa kunye nokunciphisa isantya se-boom kukwehla kokuhamba kweoyile ukuya kwisilinda sokuphakamisa. Esinye sezizathu zokuhamba kwe-cylinder ephantsi kukunciphisa ukusebenza kwempompo yokusebenza. Ukunikezelwa kwamafutha okwenene kuncitshisiwe, kwaye okwesibini, ukuvulwa kwe-valve stem esebenzayo kuba yincinci. Eyesithathu kukuvuza. Le glitch ingentla inomba wentshukumo ecothayo ngenxa yokunyuka nokuhla kweemeko. Isizathu sokuqala nesesithathu sinokukhutshwa. Isizathu sokuba ukuvulwa kwesikhondo sevalve yevalvu esebenzayo ibe ncinci kukutenxa kwiprosesa yesikhondo sevalve kunye nomzimba wevalvu. Ke ngoko, le mpazamo ikhona kumzi-mveliso, kwaye ngokuphuculwa kokuchaneka komatshini, ezo ngxaki nazo ziyancipha. Isizathu sesibini kukuba uxinzelelo lomqhubi luphantsi kakhulu kwaye alukwazi ukutyhala isikhondo sevalve kwindawo echaziweyo. Kwimilinganiselo yokwenyani, kwafunyaniswa ukuba xa uxinzelelo lomqhubi wenqwelomoya luncitshiswa ukuya kutsho kwi-13kgf/cm2, isantya se-idling siyakucotha ukuya kwimizuzwana eyi-17. Ngexesha lolondolozo olululo, qala ngokususa ivalve yokhuseleko kwimpompo yokulinga kwaye ujonge ukuba undoqo wevalve kunye nentwasahlobo yokubuya yonakele. Ukuba yinto eqhelekileyo, phinda usethe uxinzelelo emva kokucoca. Ukuba umphumo wokulungelelanisa awubonakali, oku kungenxa yokunciphisa ukusebenza kwempompo yokulinga. Kuphela endaweni yomqhubi. Impompo. Ukongeza, njengoko umthamo we-oyile we-valve stem uyancipha, i-throttling kwi-valve port iya kubangela ilahleko, eya kubangela ngokuthe ngqo ukunyuka kweqondo lokushisa kweoyile. Xa le mpazamo isenzeka, kuba i-accelerator ngokuqhelekileyo iphakathi kunye nesantya esiphezulu xa isebenza, kwaye i-fuel supply yepompo inkulu, ngokuqhelekileyo ayibonakali xa iphakamisa. Xa uhla, ngokuqhelekileyo i-throttle ephantsi okanye i-idling, kwaye inkqubo yokunikezelwa kwamafutha iyancitshiswa. Ngoko ke, Isantya sokwehla siya kuthotywa kakhulu kwaye ingqalelo ekhethekileyo kufuneka ihlawulwe ngexesha lokuhlolwa.

40. Xa umatshini wonke usebenza ngokuqhelekileyo, uyayeka ngokukhawuleza ukusebenza emva kokuzibandakanya kwesibini. Jonga ukuba uxinzelelo lokusebenza kwesi sixhobo kunye nezinye iigiya ziqhelekile.

Unobangela wengxaki:I-clutch shaft yonakele.
Indlela yokulungisa ingxaki:Buyisela i-clutch shaft kwaye ulungise i-bearing clearance.

Ukujongana neengxaki eziqhelekileyo kunye nezilayishi (36-40)

Ukuba ufuna ukuthengaizincedisi umlayishixa usebenzisa isilayishi sakho okanye unomdla kuyoXCMG abalayishi, nceda uqhagamshelane nathi kwaye i-CCMIE iya kukukhonza ngentliziyo epheleleyo.
