Uxinzelelo lwamafutha e-injini ye-diesel luya kuba phantsi kakhulu okanye alukho uxinzelelo ngenxa yokuguga kwamalungu e-injini, ukudityaniswa ngokungafanelekanga okanye ezinye iimpazamo.Iimpazamo ezifana noxinzelelo olugqithisileyo lwamafutha okanye isalathisi esijikelezayo segeyiji yoxinzelelo.Ngenxa yoko, kwenzeka iingozi ekusebenziseni oomatshini bokwakha, nto leyo ekhokelela kwilahleko engeyomfuneko.
1. Uxinzelelo lwamafutha aphantsi
Xa uxinzelelo olubonakaliswe yi-fuel gauge gauge lufunyenwe luphantsi kunexabiso eliqhelekileyo (0.15-0.4 MPa), misa umatshini ngokukhawuleza.Emva kokulinda imizuzu emi-3-5, khupha igeyiji yepetroli ukujonga umgangatho kunye nobungakanani bamafutha.Ukuba ubungakanani bamafutha alanelanga, kufuneka bongezwe.Ukuba i-fuel viscosity iphantsi, izinga le-fuel liyenyuka kwaye iphunga le-fuel lenzeka, i-fuel ixutywe ne-fuel.Ukuba isibaso simhlophe qhwa, ngamanzi axutywe kwisibaso.Jonga kwaye uphelise isibaso okanye ukuvuza kwamanzi kwaye ubuyisele isibaso njengoko kufuneka.Ukuba i-fuel ihlangabezana neemfuno zolu hlobo lwe-injini ye-diesel kwaye ubuninzi banele, khulula iplagi ye-screw ye-paseji enkulu yamafutha kwaye ujike i-crankshaft.Ukuba i-fuel engaphezulu ikhutshwe, ukuchithwa kwe-mating ye-bearing engundoqo, i-rod bearing bearing kunye ne-camshaft bearing ingaba nkulu kakhulu.Ukukhutshwa kwempahla kufuneka kuhlolwe kwaye kulungiswe.Ukuba kukho imveliso encinci yamafutha, inokuvaleka isihluzo, ukuvuza kwevalve yokunciphisa uxinzelelo okanye uhlengahlengiso olungafanelekanga.Ngeli xesha, isihluzi kufuneka sicocwe okanye sihlolwe kwaye ivalve yokunciphisa uxinzelelo ihlengahlengiswe.Ukulungelelaniswa kwevalve yokunciphisa uxinzelelo kufuneka kuqhutywe kwindawo yovavanyo kwaye akufanele kwenziwe ngokuthanda.Ukongezelela, ukuba ipompo yepetroli igugile kakhulu okanye i-gasket ye-seal yonakaliswe, ibangela ukuba ipompo yepetroli ingayipompa i-fuel, iya kubangela ukuba uxinzelelo lwe-fuel luphantsi kakhulu.Ngeli xesha, kuyimfuneko ukujonga nokulungisa impompo yamafutha.Ukuba akukho nto ingaqhelekanga ifunyaniswayo emva kokutshekishwa okungentla, oko kuthetha ukuba igeyiji yoxinzelelo lwamafutha ayisebenzi kwaye kufuneka kutshintshwe igeyiji yoxinzelelo lwamafutha entsha.
2. Akukho xinzelelo lwamafutha
Ngethuba lokusebenza koomatshini bokwakha, ukuba isalathisi se-fuel sikhanyisa kwaye isalathisi se-fuel gauge pointer point to 0, umatshini kufuneka umiswe ngokukhawuleza kwaye umlilo kufuneka umiswe.Emva koko khangela ukuba umbhobho wamafutha uvuza kakhulu na ngenxa yokugqabhuka ngesiquphe.Ukuba akukho kuvuza kwamafutha kuninzi kumphandle we-injini, khulula ukudityaniswa kwegeyiji yoxinzelelo lwamafutha.Ukuba amafutha aphuma ngokukhawuleza, igeyiji yoxinzelelo lwepetroli yonakele.Ekubeni i-fuel filter ifakwe kwibhloko ye-cylinder, kufuneka ngokubanzi kubekho i-cushion yephepha.Ukuba i-cushion yephepha ifakwe ngokungalunganga okanye i-fuel inlet hole idibaniswe ne-fuel hole yesizwe, i-fuel ayikwazi ukungena kwi-passage enkulu.Oku kuyingozi kakhulu, ngakumbi kwi-injini ye-diesel esanda kulungiswa.Ukuba akukho ziganeko zingaqhelekanga zifunyenweyo ngezi zitshekisho zingentla, impazamo isenokuba kwimpompo yamafutha kwaye impompo yamafutha kufuneka ijongwe kwaye ilungiswe.
3. Uxinzelelo lwamafutha olugqithisileyo
Ebusika, xa i-injini ye-diesel isanda kuqaliswa, kuya kufunyanwa ukuba uxinzelelo lwe-fuel lukwicala eliphezulu kwaye luya kuhla luye kwisiqhelo emva kokufudumeza.Ukuba ixabiso elibonisiweyo legeyiji yoxinzelelo lwamafutha lisadlula ixabiso eliqhelekileyo, ivalve yokunciphisa uxinzelelo kufuneka ihlengahlengiswe ukuhlangabezana nexabiso elichaziweyo.Emva kokugunyaziswa, ukuba uxinzelelo lwamafutha lusephezulu kakhulu, uphawu lwe-fuel kufuneka luhlolwe ukuze kubonwe ukuba i-viscosity yamafutha iphezulu kakhulu.Ukuba i-fuel ayinayo i-viscous, mhlawumbi i-lubricating fuel duct ivaliwe kwaye ihlanjululwe nge-diesel fuel ecocekileyo.Ngenxa ye-lubricity embi ye-diesel fuel, kunokwenzeka kuphela ukujikeleza i-starter nge-crankshaft ye-3-4 imizuzu ngexesha lokucoca (qaphela ukuba injini kufuneka ingaqaliswa).Ukuba injini kufuneka iqaliswe ukucoca, inokucocwa emva kokuxuba i-2/3 yepetroli kunye ne-1/3 yepetroli engekho ngaphezu kwemizuzu emi-3.
4. Isalathisi segeyiji yoxinzelelo lwamafutha sijikela emva naphambili
Emva kokuqala i-injini ye-diesel, ukuba i-pointer ye-fuel pressure gauge i-oscillates ngasemva naphambili, i-gauge ye-fuel kufuneka ikhutshwe kuqala ukujonga ukuba i-fuel yanele, kwaye ukuba akunjalo, i-fuel efanelekayo kufuneka yongezwe ngokuhambelana nomgangatho.Ivalve ye-bypass kufuneka ihlolwe ukuba kukho amafutha aneleyo.Ukuba i-valve ye-bypass spring ikhubazekile okanye ayinayo i-elasticity eyaneleyo, i-valve ye-bypass spring kufuneka itshintshwe;Ukuba ivalve ye-bypass ayivali ngokufanelekileyo, kufuneka ilungiswe
