Mhando dzakasiyana dzemoto usina kunaka unoburitsa maburrs.

Kupisa kwakashata kunokonzerwa nejekiseni risina kuenzana remanozzles rinongori mumajini ejekiseni akawanda. Kupisa kwakashata kunokonzerwa nekuwanda kana kuonda musanganiswa wemafuta muhumburumbira imwe kunokonzerwa nemafuta akawandisa kana mashoma anobaiwa nemuromo wega wega (muromo wakavharwa kana kubatirwa). Kana chiyero chemhepo-mafuta emusanganiswa wemhepo-mafuta mucylinder imwe kana akati wandei peturu ichipfuura njodzi, kudzima kwakashata kunoitika kana reshiyo yemafuta emhepo ichipfuura 17: 1, uye kupisa kwakashata kunoitika kana reshiyo yemafuta emhepo yakaderera kupfuura 13: 1, iyo inoguma nekupisa kwakashata kunokonzerwa nekusagadzikana jekiseni remafuta kubva kune jekiseni remafuta. Kazhinji, inogona kutongwa nekusabvisa mukana wekupisa kwakashata kunokonzerwa neiyo ignition system, kusabatidza kwakashata kwecylinder pressure uye vacuum leak yeimwe silinda. Unbalanced fuel injection. Iyo oscilloscope yemotokari inogona kushandiswa kubvisa kudzima kwakashata kunokonzerwa neiyo self-ignition system uye cylinder pressure (kuwana hurombo hunokonzerwa neiyo ignition system uye dambudziko re dynamic balance cylinder pressure). Kubvisa iyo vacuum kuvuza inoenderana nemasilinda ega, propane (yekudya yakawanda, carburetor pad, nezvimwewo) inowanzowedzerwa munzvimbo kana yakatenderedza iyo vacuum leak inogona kuitika, uye panguva imwe chete, sezvambotaurwa, iyo chiratidzo waveform yeokisijeni. sensor inocherechedzwa kubva kune oscilloscope kuzadzisa chinangwa. Kazhinji, mune yakawanda-point mafuta jekiseni injini, kana misfire inokonzerwa nemhando A, B, uye C isingagone kuratidzwa, ipapo mukana wekusaenzana unokonzera kusakwana kwakakomba mune waveform yeokisijeni sensor inogona kutariswa. Mitemo yekutonga iyo clutter yeokisijeni sensor Kana paine pachena clutter pachiratidzo cheokisijeni sensor, iyo isina kujairika kune inotongwa sisitimu, inowanzo perekedzwa neinodzokororwa uye testable injini kutadza pakumhanya kusingaite (semuenzaniso, kugogodza pane imwe silinda. kubatidza). Kazhinji, kana clutter iri pachena, kukanganisa kweinjini kunozopedzisira kwave kwakabatana nemhando dzakasiyana-siyana dzemasaisai, uye clutter pasina injini yekukanganisa haisi nyore kubvisa (iyo yakarurama mune dzimwe nguva), ndiko kuti, apo iwo mapeji ega ega pane waveform haana chekuita neinjini kukanganisa, hazvigoneke kubviswa mukugadzirisa. Kupfupisa, mutemo wekutonga clutter ndewekuti: Kana zvichigona kugumiswa kuti hapana vacuum leakage mune yakawanda yekudyara, zviri mukati memahydrocarbons (HC) uye oxygen mumhepo yekubuda gasi zvakajairika, uye kutenderera kana kusashanda kumhanya kwe. injini yacho yakadzikama, ipapo clutter inogona kugamuchirwa kana yakajairika.
