I-Diesel Injini yokucindezela kukaphethiloli izoba ngaphansi kakhulu noma hhayi ingcindezi ngenxa yokugqokwa kwezingxenye zenjini, umhlangano ongafanele noma amanye amaphutha. Amaphutha afana nokucindezela kukagesi ngokweqile noma i-pointer ye-oscillating yokucindezela kwegeji. Ngenxa yalokho, izingozi zenzeka ekusebenziseni imishini yokwakha, okuholela ekulahlekelweni okungadingekile.
1. Ingcindezi ephansi kaphethiloli
Lapho ingcindezi eboniswa yi-Fuel Pressure Gauge itholakala iphansi kunenani elijwayelekile (0.15-0.4 MPA), vala umshini ngokushesha. Ngemuva kokulinda imizuzu engama-3-5, khipha igeji kaphethiloli ukuze uhlole ikhwalithi nenani likaphethiloli. Uma inani likagesi alwanele, kufanele lingezwe. Uma i-viscosity kaphethiloli iphansi, izinga likaphethiloli likhuphuka futhi kwenzeka iphunga likagesi, uphethiloli uxutshwe nophethiloli. Uma uphethiloli ungoMily White White, amanzi axutshwe uphethiloli. Bheka futhi ususe ukuvuza uphethiloli noma ukuvuza kwamanzi bese ushintsha uphethiloli njengoba kudingeka. Uma uphethiloli uhlangabezana nezidingo zalolu hlobo lwenjini yedizili futhi inani lanele, khulula ipulaki yesikulufa sendima enkulu kaphethiloli bese uguqula i-crankshaft. Uma uphethiloli othe xaxa ukhishwa, imvume yokuhlangana yokuthwala okuphambili, ukuxhuma induku ephethe induku kanye ne-camshaft ukuthwala kungaba nkulu kakhulu. Ukuvulwa kwe-bearing kufanele kuhlolwe futhi kulungiswe. Uma kunokukhishwa okuncane kukaphethiloli, kungavinjelwa isihlungi, ukuvuza kwengcindezi kukhawulela i-valve noma ukulungiswa okungafanele. Ngalesi sikhathi, isihlungi kufanele sihlanzwe noma sihlolwe futhi sicindezelwe i-valve elungisiwe. Ukulungiswa kwe-Varvel I-Valve ekhawulelwe kufanele kwenziwe ekumeni kokuhlola futhi akufanele kwenziwe ngentando. Ngaphezu kwalokho, uma ipompo kaphethiloli igqokwa kakhulu noma i-gasket ye-Seal ilimele, okwenza ukuthi ipompo kaphethiloli ingabi ukupompa uphethiloli, kuzokwenza futhi kube nengcindezi kaphethiloli ephansi kakhulu. Ngalesi sikhathi, kuyadingeka ukuhlola nokulungisa iphampu yamafutha. Uma kungekho okungajwayelekile okutholakala ngemuva kwamasheke angenhla, kusho ukuthi igeji yengcindezi kaphethiloli iphelelwe yi-oda futhi igeji entsha yokucindezela kawoyela idinga ukushintshwa.
2. Akukho ukucindezela kukagesi
Ngesikhathi sokusebenza kwemishini yokwakha, uma inkomba kaphethiloli ikhanyisa kanye ne-pocket Pressure Gauge Pointer ikhomba ku-0, umshini kufanele umiswe ngokushesha bese umlilo umiswe. Bese uhlola ukuthi ngabe ipayipi likaphethiloli livuza kakhulu ngenxa yokuqhuma okungazelelwe. Uma kungekho ukuvuza kwamafutha amakhulu enjini yangaphandle, kukhulula ukuhlanganiswa kwegeji yengcindezi kaphethiloli. Uma uphethiloli uphuthuma ngokushesha, igeji yokucindezela kukaphethiloli yonakele. Njengoba isihlungi sikaphethiloli senziwe ku-cylinder block, kufanele kube khona i-cushion yephepha. Uma i-cushion yephepha ifakwe ngokungalungile noma i-petrol inlet hole ixhumeke nomgodi kazwelonke kaphethiloli, uphethiloli awukwazi ukungena endimeni enkulu kaphethiloli. Lokhu kuyingozi impela, ikakhulukazi enjini yedizili evele yagcwala. Uma kungekho nto engajwayelekile etholakala ngamasheke angenhla, iphutha kungenzeka libe sephampu kawoyela kanye nepompo kaphethiloli kudingeka ihlolwe futhi ilungiswe.

Ebusika, lapho injini yedizili isaqala nje, izotholakala ukuthi ukucindezela kukaphethiloli kusehlangothini oluphakeme futhi kuzokwehla kokujwayelekile ngemuva kokushiswa kabusha ngemuva kokushiswa. Uma inani elikhonjisiwe le-Fuel Pressure Gauge lidlula inani elijwayelekile, i-valve yokucindezela kufanele ilungiswe ukuze ihlangabezane nenani elishiwo. Ngemuva kokukhomisha, uma umfutho kaphethiloli usephezulu kakhulu, umkhiqizo wamafutha udinga ukuhlolwa ukuze ubone ukuthi ngabe i-petroly viscosity ephezulu kakhulu. Uma uphethiloli ungaboni kahle, kungenzeka ukuthi i-duct kaphethiloli yokuthambisa ivaliwe futhi ihlanzwe ngophethiloli ohlanzekile wedizili. Ngenxa yokugcotshwa kwe-diebity kawoyela wedizili, kungenzeka kuphela ukushintshanisa i-Starter nge-crankshaft imizuzu emi-3-4 ngesikhathi sokuhlanza (Qaphela ukuthi injini akufanele iqale). Uma injini kufanele iqalwe ngokuhlanza, ingahlanzwa ngemuva kokuxubana ngo-2/3 kaphethiloli kanye no-1/3 wamafutha angadluli imizuzu emi-3.
4. I-pointer ye-Fuel Pressure Gauge Oscillates emuva naphambili
Ngemuva kokuqala injini yedizili, uma inkomba ye-Fuel Pressure Gauge Oscillates emuva naphambili, igeji kaphethiloli kufanele ikhishwe kuqala ukuze ihlole ukuthi ngabe uphethiloli wanele, futhi uma kungenjalo, uphethiloli ofanelekayo kufanele wengezwe ngokwezinga. I-Bypass Valve kufanele ihlolwe uma kukhona uphethiloli owanele. Uma i-Bypass Valve Spring ichithekile noma inokuqina okunganele, i-Bypass Valve Spring kufanele ithathelwe indawo; Uma i-bypass valve ayivali kahle, kufanele ilungiswe
