Indandatho yepiston.
Indandatho yePiston (Indandatho yePiston) isetshenziselwa ukufaka umsele wepiston ngaphakathi kwendandatho yensimbi, indandatho yepiston ihlukaniswe izinhlobo ezimbili: indandatho yokucindezela kanye nendandatho kawoyela. Indandatho yokucindezela ingasetshenziswa ukuvala igesi exubile evuthayo ekamelweni lokushisa; Indandatho kawoyela isetshenziselwa ukuklwebha uwoyela owengeziwe kusilinda. Indandatho yepiston uhlobo lwendandatho yensimbi enwebekayo enokuguquguquka okukhulu kokukhula kwangaphandle, ehlanganiswe kuphrofayili kanye nomsele wayo ohambisanayo. Amasongo episton aphindaphindayo najikelezayo ancike ekwehlukeni kwengcindezi yegesi noma uketshezi ukuze akhe uphawu phakathi kwendilinga yangaphandle yendandatho kanye nesilinda kanye nohlangothi olulodwa lwendandatho kanye nomsele wendandatho.
Umsebenzi wendandatho yepiston uhlanganisa ukuvala, ukulawula uwoyela (ukulawula uwoyela), ukuqhuba ukushisa (ukudlulisa ukushisa), isiqondiso (ukusekela) izindima ezine. Ukuvala: kubhekisela ekuvaleni igesi, ungavumeli igesi yegumbi lokusha ivuza iye ku-crankcase, ukuvuza kwegesi kulawulwa okungenani, kuthuthukise ukusebenza kahle kokushisa. Ukuvuza komoya ngeke kunciphise amandla enjini kuphela, kodwa futhi kuzobangela ukuwohloka kwamafutha, okuwumsebenzi oyinhloko wendandatho yegesi; Lungisa uwoyela (ukulawula uwoyela): uwoyela wokugcoba owengeziwe odongeni lwesilinda uyakhuhla, futhi udonga lwesilinda lumbozwe ngefilimu encane kawoyela ukuqinisekisa ukugcotshwa okuvamile kwesilinda nepiston nendandatho, okuwumsebenzi oyinhloko wendandatho kawoyela. Ezinjinini zesimanje ezinesivinini esikhulu, kugxilwa kakhulu endimeni yefilimu kawoyela yokulawula indandatho yepiston; Ukuqhuba ukushisa: ukushisa kwepiston kudluliselwa ku-liner yesilinda ngendandatho yepiston, okungukuthi, umphumela wokupholisa. Ngokusho kwedatha ethembekile, u-70 ~ 80% wokushisa okutholwa ngenhla kwepiston yepiston engapholi uhlakazwa ngendandatho yepiston uye odongeni lwesilinda, kanti u-30 ~ 40% wepiston yokupholisa uhlakazwa ngendandatho yepiston uye odongeni lwesilinda; Ukusekela: Indandatho yepiston igcina ipiston isilinda, ivimbela ukuxhumana okuqondile phakathi kwepiston nodonga lwesilinda, iqinisekisa ukunyakaza okubushelelezi kwepiston, inciphisa ukumelana nokungqubuzana, futhi ivimbela ipiston ekushayeni isilinda. Ngokuvamile, ipiston yenjini kaphethiloli isebenzisa amasongo amabili egesi kanye nendandatho eyodwa kawoyela, kuyilapho injini yedizili ivame ukusebenzisa amasongo amabili kawoyela kanye nendandatho eyodwa kaphethiloli.
Indlela efanele yokufaka indandatho ye-piston yile elandelayo:
1. Okokuqala udinga ukufaka indandatho kawoyela, bese kuba indandatho yegesi, i-oda liqala phansi liye phezulu;
2. Uma indandatho ngayinye ifakiwe, ukuvulwa kwendandatho yepiston akufanele kunwetshwe kakhulu, kwanele nje ukungena episton;
3. Faka indandatho yamafutha ehlanganisiwe:
Faka indandatho ye-liner emseleni wendandatho kawoyela we-piston, qaphela ukuthi ukuvuleka kwendandatho ye-liner akukwazi ukugqagqana; Faka amapuleti ensimbi aphansi naphezulu ngaphandle kokusebenzisa amathuluzi ukuvula izikhala. Uma ufaka, qala ubambe umkhawulo owodwa wepuleti lensimbi elingezansi endaweni yesikhala sendandatho, cindezela indawo yokuvula ipuleti lensimbi ngesithupha sakho, slayida isithupha sesinye isandla endaweni yesikhala sendandatho eceleni kwepuleti lensimbi, bese ulayisha ipuleti lensimbi elingaphezulu ngendlela efanayo. Ungafaki amapuleti ensimbi aphezulu naphansi kolunye uhlangothi lwendandatho ye-liner; Ukuze ugweme ukugqagqana okungenzeka kwezikhala zendandatho ye-liner lapho i-piston icindezelwa ku-cylinder, gxilisa izikhala zepuleti eliphezulu neliphansi ngamajoyinti endandatho ye-liner ngama-degree angu-90 kuya kwangu-120. Ngemva kokufaka, jikisa kancane indandatho kawoyela ehlanganisiwe ngesandla, futhi kufanele ibe bushelelezi ngaphandle kokunamathela.
4. Ukufakwa kwendandatho yegesi:
Sebenzisa amathuluzi akhethekile ukufaka izindandatho ezimbili zegesi kanye nendandatho eyodwa yegesi ngokulandelana, ungaphindiseli emuva indandatho yokuqala yegesi kanye nendandatho yesibili yegesi; Uma ifakiwe, uhlangothi luphawulwe (HYR, HY, CSR, TLK, ALS, H, R, njll.). Kufanele lubheke phezulu (ukuqondisa ikhanda le-piston); Nyakazisa ukuvulwa kwendandatho yegesi ngamadigri angu-180, ungaphenduli ukuvulwa uye ngakwephini le-piston.
5. Ngaphambi kokuhlanganisa indandatho yepiston kusilinda, kubalulekile ukulungisa indawo yokuvula yendandatho ngayinye yepiston.
Umsebenzi wendandatho yepiston:
1. Umphumela wokuvala
Indandatho yepiston ingagcina uphawu phakathi kwepiston nodonga lwesilinda, futhi ukuvuza kulawulwa okungenani, okuthwalwa yindandatho yegesi. Ingavimbela isilinda kanye nepiston noma isilinda kanye nendandatho yepiston ngenxa yokuvuza komoya phakathi kokuluma; Ingavimbela futhi ukwehluleka okubangelwa ukuwohloka kwamafutha okugcoba.
Isinyathelo 2 Ukulawula ukushisa
Indandatho yepiston ingadlulisela futhi isabalalise ukushisa okuphezulu okubangelwa ukusha odongeni lwesilinda, futhi ingadlala indima ekupholiseni ipiston.
3. Umsebenzi wokulawula uwoyela
Indandatho yepiston ingaklwebha uwoyela wokugcoba onamathele odongeni lwesilinda ukuze kugcinwe ukusetshenziswa kwamafutha okuvamile, okuthwalwa yindandatho kawoyela.
4. Umphumela wokusekela
Indandatho yepiston iya phezulu naphansi kusilinda, futhi ubuso bayo obushelelayo buthwalwa ngokuphelele yindandatho yepiston, okuvimbela ipiston ukuthi ixhumane nesilinda ngqo futhi idlale indima yokusekela.
Kunezinhlobo ezimbili zamasongo e-piston: amasongo egesi namasongo kawoyela. Indandatho yegesi isetshenziselwa ukuqinisekisa ukuvalwa phakathi kwe-piston nesilinda kanye nokuvala umoya ocindezelwe egumbini lokushiswa. Indandatho kawoyela isetshenziselwa ukuklwebha uwoyela owengeziwe esilinda, okungavimbela uwoyela ukuthi ungaphumi ungene esilinda bese usha.
