I-Diesel Injector Fuel Injector 0445110743 Bosch ye-BMW, ​​Mini

Uhlelo lwesitimela oluvamile lubhekisela ohlelweni oluvaliwe lwe-loop olwakhiwe ipompo likawoyela elinomfutho ophezulu, inzwa yokucindezela kanye neyunithi yokulawula i-electronic (ECU), ehlukanisa ngokuphelele isizukulwane sokucindezela komjovo kanye nenqubo yomjovo komunye nomunye, ehluke ngokuphelele uhlelo lwangaphambilini lomjovo wedizili oluqhutshwa ama-camshafts. Iphampu kawoyela enengcindezi ephezulu yokuletha uphethiloli osezingeni eliphezulu kumzila kawoyela, ngokusebenzisa ingcindezi kawoyela esitimeleni ukuze kuzuzwe ukulawula okuqondile, ukuze umfutho wepayipi kawoyela ophakeme uzimele ngaphandle kwejubane lenjini, unganciphisa kakhulu. izinga lomfutho wokunikezwa kukawoyela wenjini ye-diesel ngokushintsha kwesivinini senjini.

Uhlelo lomjovo wesitimela lukadizili olujwayelekile luqukethe uhlelo olusebenza ngamanzi kanye nohlelo lokulawula ngogesi. Phakathi kwazo, i-hydraulic system ihlukaniswe yaba yi-low-pressure hydraulic system kanye ne-high-pressure hydraulic system. I-low-pressure hydraulic system ihlanganisa ithangi likaphethiloli, ipompo yokudlulisa uphethiloli, isihlungi sikaphethiloli kanye nomugqa wamafutha ophansi; Uhlelo olunomfutho ophezulu we-hydraulic luhlanganisa ipompo yokucindezela okuphezulu, umzila wesitimela kawoyela ocindezelwe kakhulu, umjovo kanye nepayipi likawoyela elinomfutho ophezulu; I-Electronic Diesel Control (EDC) ihlanganisa izinzwa, i-Electronic Control Unit (ECU), ama-actuator (okuhlanganisa ama-injection anamavalvu e-solenoid, ama-valve okulawula ukucindezela, amayunithi okulawula ipulaki elikhanyayo, izilawuli ze-booster pressure, izilawuli zokujikeleza kwegesi exhaust, ama-throttle valve, njll.) kanye nezintambo amahhanisi.

Ipayipi lesitimela elivamile lidlala indima yokusabalalisa uphethiloli wengcindezi ephezulu ohlinzekwa yiphampu kawoyela enengcindezi ephezulu kumjovo ngamunye. Ukucindezela kukadizili epayipini likaloliwe elivamile lingagcinwa kububanzi obungu-130~160 MPa. Ipayipi lesitimela elivamile lifakwe inzwa yokucindezela, edlulisela isignali evamile kawoyela wesitimela eyunithi yokulawula ye-elekthronikhi (ECU), futhi iyunithi yokulawula ye-elekthronikhi isebenzisa ukulawulwa kwempendulo ku-valve ye-PCV ukuze kunzinzise umfutho kawoyela wesitimela ovamile kulokho okuhlosiwe. inani. I-flow buffer (flow limiter) iqinisekisa ukuthi ukunikezwa kukawoyela kumjovo kuyanqanyulwa lapho ukuhluleka kokuvuza kukaphethiloli kwenzeka kumjovo, futhi kunganciphisa ukuguquguquka kwengcindezi kumzila wesitimela ovamile kanye nepayipi likawoyela elinomfutho ophezulu; I-pressure limiter iqinisekisa ukuthi ingcindezi kusitimela we-high-pressure iphuma ngokushesha uma kwenzeka kuba nokucindezela okungavamile.
