Mukuchengetedza kwe-high-pressure common rail systems, high-pressure oil circuit failure idambudziko rinowanzoitika. Kutadza kweiyo high-pressure oil circuit kunogona kukonzera kutadza kutanga, kuomerwa nekutanga, nekumira panguva yekushanda. Idzi imhosvaphenomenaizvo zvinowanzonetsa vashandi vekuchengetedza.

Iyo Fuel Injector Haisi Kupinza Mafuta

Kana jekiseni rikatadza kubaya mafuta, zviratidzo zvakaita sejitter yakakura isingaite uye pasina pulsation mupombi yemafuta ekudzvanya inowanzoitika. Panguva imwecheteyo, kana chimbo chekuongorora chikanganiso chikashandiswa kuona, chinogona kuratidza ruzivo rwakadai sekuwedzera kukurumidza kumhanyisa mafuta vhoriyamu uye jekiseni remafuta dhiraivha kutadza.

Solution

1.Kutanga, tarisa kana pane dambudziko nejekiseni drive circuit, ingave yakakuvadzwa, kana pane pfupi pfupi kana kushayikwa kwedunhu rakazaruka.

2.Cheka pombi yemafuta epamusoro-soro yekudonha.

3.Check kana jekiseni remafuta pacharo rakashata, senge yakawandisa kabhoni deposits inokonzera kunamatira, kana jekiseni remafuta rakundikana.

Rail Pressure Yakaoma Kumisa

Kana kukanganisa kukaitika kuti njanji yakaoma kumisa, kushandisa mudziyo wekuongorora kuti uone kukanganisa uchawana ruzivo nezve njanji yekumanikidza yakadzikira. Izvi zvinowanzokonzerwa nezvinetso zvakadai sekushaya kukwana kwehuni yekupa simba yepombi yepamusoro-soro, kukundikana kwevhavha yemafuta metering valve, kana kuvharwa kwechisimbiso chekubatanidza kwepombi yepamusoro.

Solution

1. Tarisa uone kana pombi yemafuta epamusoro-soro inogona kupa zvakakwana njanji.

2. Kana iyo pombi yepamusoro-yepamusoro pepombi yakajairika, tarisa kana mafuta ekuisa metering valve akanganisa.

3. Tarisa kuti indentation pamusoro pechisimbiso chepamusoro pakubatanidzwa pakati pepombi yepamusoro yekubatanidza pombi uye jekiseni inowanzoitika.

Rail Pressure Inoramba Yakanyanya Kunyanya

Kana kukanganisa uku kuchiitika, chimbo chekuongorora chinokanganisa chinogona kushandiswa kuona kuti deraiilment pressure inodarika muganho kwenguva yakareba kupfuura kukosha kwakatarwa. Zvinowanzokonzeresa dambudziko iri kukanganisa metering uye kumanikidza kudzikamisa valve kutadza.

Solution

1. Tarisa mafuta metering valve kuti haashande.

2. Tarisa uone kana vharuvhu inomisa pressure ye common rail system yakanganisa.
