Dizilo Injector Fuel Injector 0445110743 Bosch ya BMW, Mini

Dongosolo la njanji wamba limatanthawuza njira yotsekeka yopangidwa ndi pampu yamafuta othamanga kwambiri, sensa yamagetsi ndi gawo lowongolera zamagetsi (ECU), lomwe limalekanitsa m'badwo wa kuthamanga kwa jekeseni ndi jekeseni wina ndi mnzake, womwe ndi wosiyana kwambiri. jekeseni wa dizilo wam'mbuyo woyendetsedwa ndi ma camshafts. Ndi pampu yamafuta othamanga kwambiri kuti ipereke mafuta othamanga kwambiri ku njanji yamafuta, kudzera pakuthamanga kwamafuta mu njanji kuti akwaniritse kuwongolera bwino, kotero kuti kuthamanga kwa chitoliro chamafuta othamanga kwambiri sikudalira liwiro la injini, kumatha kuchepetsa kwambiri. kuchuluka kwa mafuta a injini ya dizilo ndi kusintha kwa liwiro la injini.

Dongosolo la jakisoni wa njanji wa dizilo limapangidwa ndi hydraulic system ndi electronic control system. Pakati pawo, ma hydraulic system amagawidwa kukhala otsika-pressure hydraulic system ndi high-pressure hydraulic system. Dongosolo la hydraulic low-pressure hydraulic system limaphatikizapo tanki yamafuta, pampu yotumizira mafuta, fyuluta yamafuta ndi mzere wamafuta ochepa; Dongosolo lamphamvu la hydraulic system limaphatikizapo pampu yothamanga kwambiri, njanji yamafuta othamanga kwambiri, injector ndi chitoliro chamafuta othamanga kwambiri; Electronic Diesel Control (EDC) imaphatikizapo masensa, Electronic Control Unit (ECU), ma actuators (kuphatikiza ma jekeseni okhala ndi ma valve solenoid, ma valve owongolera kuthamanga, mayunitsi owongolera ma plug, owongolera mphamvu, owongolera mpweya wotulutsa mpweya, ma valve othamanga, ndi zina zambiri.) zingwe.

Chitoliro cha njanji wamba chimagwira ntchito yogawa mafuta othamanga kwambiri omwe amaperekedwa ndi pampu yamafuta othamanga kwambiri ku jekeseni iliyonse. Kuthamanga kwa dizilo mu chitoliro cha njanji wamba kumatha kusungidwa mumtundu wa 130 ~ 160 MPa. Chitoliro cha njanji wamba chimakhala ndi sensor yokakamiza, yomwe imatumiza chizindikiro chamafuta amtundu wa njanji kupita kumagetsi owongolera (ECU), ndipo gawo loyang'anira zamagetsi limagwiritsa ntchito kuwongolera kwamayankho pa valavu ya PCV kuti akhazikitse kuthamanga kwamafuta a njanji ku chandamale. mtengo. Kuthamanga kwamadzi (otsika malire) kumatsimikizira kuti mafuta operekedwa kwa jekeseni amadulidwa pamene kulephera kwa mafuta kutayika mu jekeseni, ndipo kungachepetse kusinthasintha kwa kuthamanga kwa njanji wamba ndi chitoliro chapamwamba cha mafuta; The pressure limiter imatsimikizira kuti kupanikizika kwa njanji yothamanga kwambiri kumatuluka mwamsanga pakachitika kupanikizika kwachilendo.
