Auto parts chigadzirwa chinoumba imwe neimwe unit yemota yese uye inoshandisa mota. Kune marudzi akawanda ezvikamu zvemotokari, nekuvandudzwa kwemararamiro evanhu, kudyiwa kwevanhu kwemotokari kuri kuwedzerawo, uye misika yezvikamu zvemotokari iri kuramba ichikura. Mumakore achangopfuura, vagadziri vezvikamu zvemotokari vari kukurawo nekukurumidza. Kutanga, injini cylinder sealing test
Pane zvinhu zvinomwe zvinokanganisa kuiswa chisimbiso kwecylinder, kunyanya kupfeka silinda, kukuvara kwepiston mhete, kupfeka piston, kukuvara kwechigaro chevharuvhu, kupfeka gwara revhavha, kukuvara kwecylinder gasket, valve clearance uye zvimwe zvinhu zvedambudziko.
Ndedzipi nzira dzakajairika dzekuongorora? Iyo huru kuyerwa silinda kumanikidzwa, crankcase gasi chiteshi, silinda kuvuza uye kudonha chiyero, yekupinda pombi vacuum, silinda piston boka nekuda kwekupfeka kwakanyanya kunokonzerwa neabnormal vibration kuyerwa, crankcase kupfeka simbi ndiko kutsunga kwechikamu chemukati.
Pakuyera kwecylinder compression pressure, ndiyo inonyanya kudzvanywa pakupera kwechina-stroke injini compression. Nekuda kwekudzvanywa kwecylinder uye viscosity yemafuta uye cylinder piston boka, kugadziridzwa kwevhavhavha yemagetsi kwakaringana, kuiswa chisimbiso kwe cylinder pad nezvimwe zvinhu, saka, kana uchiyera kudzvanywa kweinjini cylinder, unogona kuongorora. chisimbiso cheboka re cylinder piston, kana piston mhete, vharafu, cylinder pad seal yakanaka, ipapo kubvumidzwa kwevharuvhu kunofanirwa kuve kwakakodzera.
