1. Utsi hutema kana injini yedhiziri ichishanda
Kutanga, teerera kutarisa iyo air supply system. Kana injini yedhiziri isina kukwana kwemhepo, huwandu hwemhepo muimba yekupisa haigoni kuzadzisa zvinodiwa, izvo zvichaita kuti dizeli isapisa zvakakwana. Kana dhiziri isingakwanisi kupisa zvakakwana, zviri nyore kwazvo kugadzira utsi hutema pasi pekumanikidzwa kwakanyanya. Panguva ino, nzira yekupinza uye sefa yemhepo inofanirwa kutariswa kuti ione kana paine kuvharika, kana supercharger iri kushanda zvakajairika, uye kana paine kuvuza mupombi yekupinza. Panguva imwecheteyo, tarisa kurongeka kwevhavha kuti uone kuti hapana dambudziko rekudonha muzvigaro zvekutora uye kupera kwevhavha, uye dambudziko rehukama hwepiston, cylinder liner, uye piston mhete. Chechipiri, teerera kutarisa dhiziri rekupa system. Kana injini yedhiziri isina kupihwa mafuta, zvinokanganisa kusanganiswa kunotevera. Kunyange kana ikasvika kuhuwandu hwekudya, haigoni kupiswa zvachose, uye utsi hutema huchagadzirwa panguva ino. Munguva yekuongorora, pfungwa dzinotevera dzinofanirwa kucherechedzwa: Chenjerera kutarisa pombi yepamusoro yemafuta kuti uone kuti inosangana nezvinodiwa. Chenjerera kutarisa kupihwa kwemafuta kuti udzivise kuwandisa kwemafuta. Ngwarira kutarisa mamiriro ekushanda kwevhavha yemafuta kuti uone kuti iri mumamiriro akanaka. Chenjerera kutarisa kushata kweatomization kunokonzerwa nekusakwana kweinjector pressure. Ngwarira kutarisa jekiseni rechipiri uye kubuda kwemafuta kweinjector. Ngwarira kutarisa dambudziko remajekiseni akawandisa ejekiseni uye jekiseni remafuta risingaenzaniswi. Chenjerera kutarisa dhiziri uye mhando.
2. Simba risina kukwana rejini injini
Munguva yekushanda kweinjini yedhiziri, zviri nyore kwazvo kuve nedambudziko resimba risina kukwana. Pakusangana nematambudziko akadai, nzira dzakawanda dzinofanirwa kushandiswa kuona chikonzero chekukanganisa. Kutanga, tarisa utsi uye zvinetso zvekupfeka. Panguva yekushanda kweinjini, vhura chivharo chemafuta. Kana chiutsi chakakora chawanikwa, zvinoreva kuti injini yedhiziri ine dambudziko guru rehutsi hushoma, zvichiratidza kuti silinda liner, piston, piston ring uye zvimwe zvikamu zvakasakara. Kana chivharo chevhavha chichivhurwa, kana utsi hwecyan uye utsi huchena huchionekwa pamudzi wevhavha, zvinoreva kuti utsi hwepamusoro hunoitika. Kana utsi hwepamusoro huchiitika, zvinoreva kuti valve uye chigaro chevharuvhu chakatsva zvakanyanya uye chakapfekwa, uye chinogonawo kukonzerwa nediki diki revharuvhu kana kusava nemvumo. Nokucherechedza chiitiko chepamusoro cheutsi, inogona kuonekwa kuti ndeipi valve kana silinda ine dambudziko rekudonha, uye matanho anofanirwa kutorwa munguva yekugadzirisa nayo. Chechipiri, tarisa kabhoni deposits uye mamiriro ekushanda. Kana madhipoziti eblack kabhoni achionekwa pachiteshi chekuburitsa cheinjini yedhiziri, yakafanana nechando chechando, uye ukobvu hwakatetepa, zvinoreva kuti injini yedhiziri iri mumamiriro ekushanda zvakanaka. Kana yakasviba uye yakajeka kabhoni deposits ichionekwa, asi iyo kabhoni deposits haina kunyorova, inoratidza kuti dizeli injini yemafuta inopedzwa zvakanyanya, uye iyo kabhoni deposits inofanira kunyatsocheneswa. Kana ukobvu hwekabhoni huchiiswa pahumburumbira yekuburitsa pombi yakakura zvakanyanya kupfuura iyo kune mamwe silinda exhaust ports, zvinoreva kuti cylinder injector haisi mumamiriro ekushanda zvakanaka, uye silinda inogona kunge isina kuvharwa zvakanaka, saka inofanirwa kuongororwa uye yakatsiviwa. Kune zviteshi zvemunhu ekunze, kana zvanyorova kana kuti mafuta, zvinoreva kuti kune huwandu hukuru hwekubuda kwemafuta mukati mehumburumbira, uye kugadzirisa kunofanirwa kuitwa nenguva. Kana ukobvu hwekabhoni inoisa pahumburumbira yekuburitsa chiteshi yakakura uye ruvara rwakasviba, zvinoreva kuti tembiricha yakadzikira uye jekiseni remafuta haripo, zvichikonzera matambudziko akakomba mushure mekupisa muinjini yedhiziri. Izvo zvinodikanwa kuve nechokwadi chekuti injini yedhiziri inoshanda nemazvo uye kugadzirisa optimization.
