Kuvhura kwevhavha yekumanikidza yekumanikidza yakakamurwa kuita maviri mamiriro: inoshanda kuvhura uye

kuvhura chete.

Active kuvhura

Paunenge uchigamuchira ruzivo rwekukanganisa kubva kune zvimwe zvine chekuita nezvikamu, iyo injini yemagetsi control unit (ECU) ichaita nzira yekudzivirira uye kuraira iyo yekumanikidza inomisa vharafu kuti ivhure (kunyangwe kana njanji isinganyanyi kukwira), nekudaro kudzivirira kwakakomba injini kutadza. Ndeipi chikamu chekutadza ruzivo chinokonzeresa ECU kuita chirongwa chekudzivirira?

1. Rail pressure sensor signal

Kana iyo njanji inomanikidza sensor inotumira njanji kudzvanya pamusoro-muganho chiratidzo kuECU, ingave yakanyanya kukwirira kana kuderera, ichaita kuti ECU iite chirongwa chekudzivirira uye kuvhura iyo yekumanikidza inomisa valve. Pane zvikonzero zvakawanda zveiyo track pressure sensor yekushuma meseji yekukanganisa. Izvo zvakakosha ndeyekusajairika kwemafuta inlet kudzvanywa kana kudzoserwa kweoiri, sekunge kusakwana kwemafuta mumutsara weoiri-yakadzika, kupfeka kwepombi-yakanyanya-kudzvanywa, kuvharika kwakashata kwevhavha inodzikamisa, uye yakawandisa mafuta ekudzosa vhoriyamu kubva kune jekiseni. . Oil line yakavharwa, etc.

2. Fuel metering valve kutadza chiratidzo

Kuti uvandudze kushanda zvakanaka, iyo yakakwirira-yekudzvanya pombi yeyakajairwa njanji sisitimu inoshongedzerwa metering unit yehuni yekudzora huwandu hwemafuta, iyo inonzi mafuta metering valve. Iyo inodzora kudzvanywa kwemafuta mune yakakwira-kudzvanywa njanji nekugadzirisa huwandu hwemafuta anopinda pombi yepamusoro. Iyo ECU inodzora iyo metering unit nekushandura duty cycle mukati me metering unit kuburikidza nepulse masaini. Kana iyo metering valve ikakundikana, zvinoreva kuti ECU haigone kupedzisa kutonga kwakaringana kwekumanikidza kwenjanji. Naizvozvo, kana ichinge yawana ruzivo rwekukanganisa rwakabatana nevhavhavhavha, senge pfupi dunhu, rakavhurika redunhu kukanganisa, kana kusajairika tembiricha kukanganisa, ECU ichaita chirongwa chekudzivirira kudzikamisa Ivhavha yekumanikidza ichavhurawo.

3. Sensor power supply module 3 kukanganisa chiratidzo

Iyo sensor magetsi ekupa module 3 inopa 5V magetsi ekupa akawanda ma sensors, kusanganisira njanji yekumanikidza sensors. Kana iyo sensor magetsi ekupa module 3 ikatadza, zvinoreva kuti ese ma sensors ayo ane basa nawo anogona kushanda zvisina kujairika. Naizvozvo, kana ECU yangowana ruzivo rwekukanganisa ine chekuita ne sensor power supply module 3, ichaita chirongwa chekudzivirira uye iyo yekumanikidza inomisa vharafu ichavhura.

4. ECU inoenderana nezvikanganiso

Semukuru-mukuru weiyo common rail system, mhedzisiro yekutadza kweECU inogona kufungidzirwa. Naizvozvo, kana sisitimu yaona ECU-inoenderana nekukanganisa ruzivo, ichaitawo nzira yekudzivirira.

Kuvhura chete

Zvikonzero zvakajairwa zvekuvhurika zvinosanganisira: mafuta metering vharafu kana yekuyamura vharafu kutadza, yakanyanya-kudzvanywa pombi kutadza, njanji yekumanikidza sensor kukuvara kunokonzeresa kumanikidzwa kwenjanji kusadzora, kuvharika kwepombi yemafuta, nezvimwe.
