I-Professional Manufacture Diesel Fuel Injector A6510702787 Common Rail Injector yezingxenye Zenjini ye-Mercedes-Benz

1. Umehluko phakathi kwamandla netorque

Ngaphansi kwezimo ezijwayelekile, ukushaywa kwesilinda kwenjini kaphethiloli kufushane. Isizathu esenza lo mklamo wamukelwe ukukhuphula isivinini esiphezulu senjini, ukuze kuqhume amandla engeziwe. Ngokuphambene nalokho, izinjini zikadizili zinaka kakhulu itorque yemoto, futhi ukushaywa kwesilinda kuhlelwa ukuba kube kude, okunganciphisa ijubane lemoto futhi kukhulise kangcono itorque. Ngakho-ke, lesi futhi isizathu esenza izimoto ezisindayo ezingekho emgwaqeni, ama-SUV, amaloli, njll. zonke zikhetha uwoyela wenjini ye-diesel njengomthombo wazo wamandla.

2. ukonga amafutha

Okubizwa ngokuthi umnotho wamafutha, ukuqhathanisa okunembile ukuqhathanisa ukusebenza kahle kwezinjini ezimbili ekuguquleni amandla ashisayo abe amandla emishini. Kodwa-ke, ngenxa yomehluko othile kubuchwepheshe benjini evela kubakhiqizi abahlukene, kunomehluko othile ekusebenzeni kahle kokuguqulwa kwamandla ashisayo ezinjini. Okwamanje, ukuguqulwa okushisayo kwezinjini zezimoto bekulokhu kuyinkinga. Ukusebenza kahle kokushisa kwezinjini eziningi zikaphethiloli kungafinyelela cishe ku-40%. Kuphela ukuguqulwa okushisayo kwezinjini ezikhiqizwa izinhlobo ezifana ne-Nissan ne-Mazda kungadlula u-40%. Ngakolunye uhlangothi, ezinjinini zikadizili, ukuguqulwa okuncane kokusebenza kahle kokushisa kungaphezu kwama-35%, futhi kulula ukweqa ama-40%. Kukhona ngisho nezinjini ezinye ukusebenza kahle kwazo ezishisayo kungadlula ama-45%. Ngakho-ke, uma idla isilinganiso esifanayo sikaphethiloli, injini kadizili ingaguqula amandla amaningi ashisayo ibe amandla asetshenziswayo, okusho ukuthi iyonga kakhulu.

Ngaphezu kwalokho, ukusebenza kahle okuphansi kokushisa kwezinjini zikaphethiloli nakho kuhlobene kakhulu nokwakheka kukaphethiloli. Ngokombono wamakhemikhali, uphethiloli kanye nedizili zakhiwe ngama-molecule amancane, futhi ku-molecule ngayinye ye-hydrocarbon compound, kunama-molecule e-petroli angu-8-10. ama-athomu e-carbon, kuyilapho ama-molecule e-diesel angafinyelela ama-athomu e-carbon angu-12-15. Uma kuphezulu okuqukethwe kwe-athomu yekhabhoni, amandla aqukethwe ngemuva kokusha abe maningi. Ngakho-ke, ukuze kuzuzwe amandla afanayo, injini kaphethiloli idinga ukujova uphethiloli omningi kunenjini kadizili, futhi ukusetshenziswa kukaphethiloli ngokwemvelo kuyoba kuphakeme.

 3. Ukuthembeka kwenjini nokuphepha

Impilo yesevisi yenjini ihlobene eduze nesivinini sokujikeleza. Lapho isivinini sokusebenza siphezulu, impilo yesevisi iba mfishane. Isibonelo, injini esetshenziswa ezimotweni zomjaho i-F1 inejubane lokungenzi lutho elingu-3,000 rpm, futhi isivinini senjini esimaphakathi singaphezu kuka-15,000 rpm lapho injini isebenza, ngakho-ke kuthatha imijaho embalwa kuphela ukuthi injini ithunyelwe ukuze izolahlwa. . Uma zibuyela eqinisweni, izinjini zikadizili zinaka kakhulu itorque ephansi, ngakho lapho amandla afanayo efinyelela isivinini esifanayo, ijubane lenjini kadizili liphansi. Ngaphezu kwalokho, ngisho nangesivinini esiphezulu, isivinini injini diesel ngokuvamile ingeqi 4500 rpm, kuyilapho injini uphethiloli has isivinini esiphezulu okungenani 6500 rpm ukuze akhiphe amahhashi amaningi. Ngakho-ke, izinjini zikadizili ezine-rpm ephansi zithembeke ngokwemvelo.

Udizili awuguquguquki futhi akulula ukuwuvutha emazingeni okushisa ajwayelekile okusebenza. Ngakho-ke, uma kwenzeka ingozi yenjini kadizili, ithuba lokuthi imoto izishise ngokuzenzekelayo nalo lincane kakhulu. Ngokungafani nemoto kaphethiloli, uma ithangi likaphethiloli selivuza, yinhlansi encane kuphela engayithungela. Ngokushesha ithungele yonke imoto.
