Isenzo sesembozo segiya lesikhathi semoto.
Amagiya okulinganisa isikhathi afakwa ezinhlelweni zokungenisa kanye nezokukhipha umoya ezinjinini zokushisa zangaphakathi, emawashini nakwezinye izinhlelo zasendaweni ezinobudlelwano obulandelanayo nemisebenzi ephelele yemishini.
Izindlela ezintathu zokudlulisa zegiya lesikhathi: ukushayela ngeketanga, ukushayela ngebhande lamazinyo, ukushayela ngegiya.
Amagiya amahle nangalungile enjini yemoto aqhutshwa yibhande elinomunwe, elinezinzuzo zesakhiwo esilula, umsindo ophansi, ukusebenza okubushelelezi, ukunemba okuphezulu kokudlulisela, ukuvumelanisa okuhle, njll., kodwa amandla alo aphansi, futhi kulula ukuguga, ukwelula ukuguquguquka noma ukuphuka ngemva kokusetshenziswa isikhathi eside. Ibhande elinomunwe lisesimweni esivaliwe esembozweni sangaphandle, okuyinto enzima ukubona isimo salo sokusebenza. Kukhona imoto ye-Mitsubishi, azikho izimpawu zokuqala, ngemva kokuhlolwa kwesekethe, iphutha lisakhona, bese uvula isembozo segumbi le-valve, uthole ukuthi ingalo ye-valve rocker ayisebenzi, kutholakale ukuthi ibhande lamazinyo lesikhathi liphukile. Ngemva kokufakwa esikhundleni somkhiqizo omusha, injini ayikaqali. Ngoba, uma ibhande lamazinyo seliphukile ekusebenzeni, i-camshaft iyayeka ukusebenza, futhi i-crankshaft izoqhubeka nokujikeleza i-Engela ethile noma inani lokujika ngaphansi kwesenzo se-inertia yokujikeleza ye-flywheel noma i-inertia yedivayisi yokudlulisela. Ngalesi sikhathi, injini ayikwazi ukusebenza, futhi okubaluleke kakhulu, isigaba se-valve siyabhujiswa, futhi i-piston izogoba induku ye-valve phezulu endaweni evulekile, okuholela ekutheni i-valve ivalwe kalula. Ngakho-ke, ezinye izinjini ezinamabhande anamazinyo aphukile, noma ngabe uphawu lwegiya lesikhathi lulungiswa kabusha, futhi ibhande elisha elinamamazinyo lesikhathi liyashintshwa, injini ayikalula ukuyiqala, noma ayikwazi ukuqala kahle, kodwa umsebenzi awuvamile, futhi kwenzeka into "yokushisa", "ukudubula", amandla anganele, nomsindo owandisiwe. Kulokhu, kuphela ngokususa ikhanda lesilinda nokushintsha i-valve lapho isimo sobuchwepheshe senjini singabuyiselwa khona ngokuphelele. Isikhathi kanye nesimo sesenzo se-valve kumele kuhambisane nesimo nesikhathi sokuhamba kwe-piston, futhi i-crankshaft kanye ne-camshaft azikho ku-axis, kumele zixhunywe ngohlelo lokudlulisa, uhlelo lokudlulisa luqedwa ngamagiya amabili kanye neketanga noma ibhande, bese amagiya amabili abizwa ngokuthi amagiya okulinganisa isikhathi, amagiya amabili ayaphawulwa, Ngemva kokufaka iketanga noma ibhande ngokophawu, kungaqinisekisa ukuthi isikhathi kanye nesenzo sesenzo se-valve kunembile.
Umsebenzi wesembozo segiya lesikhathi ukuvikela igiya lesikhathi othulini nasemanzini. Indima yegiya lesikhathi ukubeka isikali sesikhathi sokuqedela imisebenzi yokulawula efanele kudivayisi yomshini.
Igiya lesikhathi liyigiya elidlala indawo yesilinganiso sesikhathi sokuqedela imisebenzi yokulawula efanele kudivayisi yomshini. Amagiya esikhathi afakwa ezinhlelweni zokungenisa kanye nezokukhipha umoya ezinjinini zokushisa zangaphakathi, emawashini nakwezinye izinhlelo zasendaweni ezinobudlelwano obulandelanayo nemisebenzi ephelele yomshini.
Indima yegiya lesikhathi: lingadlala indima yokubeka isikhathi ekuqedeni imisebenzi yokulawula efanele kudivayisi yomshini.
Izindlela ezintathu zokudlulisa zegiya lesikhathi: ukushayela ngeketanga, ukushayela ngebhande lamazinyo, ukushayela ngegiya. Amagiya amahle nangalungile enjini yemoto aqhutshwa ngebhande elinamazinyo, elinezinzuzo zesakhiwo esilula, umsindo ophansi, ukusebenza kahle, ukunemba okuphezulu kokudlulisa, ukuvumelanisa okuhle, njll., kodwa amandla alo aphansi, kulula ukuwaguga, ukuguquguquka kokuthamba noma ukuphuka ngemva kokusetshenziswa isikhathi eside, futhi akulula ukubona isimo salo sokusebenza.
Isikhathi kanye nesimo sesenzo se-valve kumele kuhambisane nesimo kanye nesikhathi sokunyakaza kwe-piston, futhi i-crankshaft kanye ne-camshaft azikho ku-axis, futhi kumele kube nohlelo lokudlulisa phakathi kwazo ukuze zixhumeke, uhlelo lokudlulisa luqedwa ngamagiya amabili kanye neketanga noma ibhande, bese amagiya amabili abizwa ngokuthi amagiya okugcina isikhathi.
Ukwehluleka kwegiya lesikhathi senjini yemoto
Uma injini isebenza, yenza umsindo oqhubekayo noma onesigqi ngaphambili kwenjini. Ngaphansi kwezimo ezivamile, uma ijubane liphezulu, umsindo uba mkhulu; Umsindo awushintshi lapho izinga lokushisa lishintsha; Umsindo womlilo oqhumayo wesilinda esisodwa awunciphi.
Izimbangela ezingaba khona zomsindo ongajwayelekile wegiya lesikhathi
(1) Isikhala senhlanganisela yegiya sikhulu kakhulu noma sincane kakhulu
(2) Ibanga eliphakathi nendawo phakathi kwembobo enkulu ye-crankshaft kanye nembobo ye-camshaft liyashintsha ngesikhathi sokusetshenziswa noma ukulungiswa, liba likhulu noma lincane; Imigqa ephakathi ye-crankshaft kanye ne-camshaft ayilingani, okuholela ekungangeni kahle kwamagiya.
(3) Ukuma kwezinyo kwegiya akucutshungulwa, ukuguquguquka ngesikhathi sokwelashwa kokushisa noma ubuso bezinyo bugugile kakhulu;
(4) Isikhala sokuluma asiqinile noma ukusika impande kwenzeka ngesikhathi sokujikeleza kwegiya;
(5) ubuso bezinyo bunezibazi, ukuqhekeka kwezinyo noma ukuphuka kwezinyo;
(6) Igiya likhululekile noma lingaphandle kwe-crankshaft noma i-camshaft;
(7) i-runout eyindilinga yobuso begiya noma i-runout ye-radial inkulu kakhulu;
(8) i-axial clearance ye-crankshaft noma ye-camshaft inkulu kakhulu;
(9) Amagiya awashintshwa ngamabili.
(10) Ngemva kokushintsha i-crankshaft kanye ne-camshaft bearing bush, isikhundla se-gear meshing siyashintshwa.
(11) igiya lokulungisa isikhathi le-camshaft likhululekile.
(12) ukulahleka kwamazinyo kwegiya lesikhathi se-camshaft, noma ukuqhuma kwe-radial yegiya.
Izici zokusebenza komsindo okungavamile kwegiya lesikhathi
1) Umsindo uyinkimbinkimbi kakhulu, ngezinye izikhathi unesigqi, ngezinye izikhathi awukho isigqi, ngezinye izikhathi uyaqhubeka.
2) Uma injini ingasebenzi noma ijubane lishintsha, kuba nomsindo ongcolile noncane embozweni wegumbi legiya ngesikhathi, futhi umsindo uyanyamalala ngemva kokuba ijubane selikhuphukile, futhi umsindo uvela lapho injini yehla ngokushesha.
3) Eminye imisindo ayithintwa izinga lokushisa kanye nokuhlolwa komlilo wesilinda esisodwa, kanti eminye ithintwa izinga lokushisa, akukho msindo lapho izinga lokushisa liphansi, futhi lapho izinga lokushisa lenyuka liye kwejwayelekile, umsindo uyavela.
4) Eminye imisindo ihambisana nokudlidliza kwesembozo segumbi legiya lesikhathi, kanti eminye imisindo ayihambisani nokudlidliza.
