Uyini umehluko phakathi kwenzwa yezinga lokushisa kwamanzi kanye nepulaki yenzwa yezinga lokushisa kwamanzi?
Inzwa yokushisa kwamanzi, eyaziwa nangokuthi inzwa yokushisa epholile, ngokuvamile iyisistimu yezintambo ezingu-2, ukusetshenziswa kwayo okuyinhloko ngu-1, ukuhlinzeka ngemingcele yokushisa okupholisa injini kumlawuli wesistimu yokuphatha injini (ECM). Le parameter yezinga lokushisa ingalawula i-adaptha yabalandeli, ukuze ilawule ifeni epholile yenjini. 2. Isignali yokushisa kwamanzi iyipharamitha ebalulekile yokubala isilinganiso somoya/samafutha (isilinganiso sikaphethiloli womoya), i-Angle ethuthukisiwe (isikhathi sokuvutha) nezinye izilungiselelo zokulinganisa.
Ipulaki yezinga lokushisa kwamanzi isebenza injongo eyodwa kuphela: ukuhlinzeka ngemingcele yezinga lokushisa elipholile lenjini kudeshibhodi yemoto. Okuwukuhlinzeka ngesignali yezinga lokushisa ku-instrumentation yemoto
Ungase ungabi nayo ipulaki lokushisa kwamanzi enjinini, kodwa kufanele ube nenzwa yokushisa kwamanzi! Ngenxa yokuthi inzwa yokushisa kwamanzi ukunikeza ikhompuyutha injini isignali, ikhompyutha generator ngokuvumelana isignali inzwa ukulawula injini fan, umjovo uphethiloli, ukuthungela, nokunye okufana transmission othomathikhi, othomathikhi air conditioning nokunye.
Itholwa kanjani isignali yenzwa yezinga lokushisa kwamanzi?
Ingaphakathi lenzwa yokushisa kwamanzi ngokuyinhloko i-thermistor, engahlukaniswa ngama-coefficients okushisa amahle futhi angalungile. I-coefficient yokushisa enhle isho ukuthi izinga lokushisa lamanzi liphakeme, ukumelana kuzoba mkhulu, kuyilapho izinga lokushisa elibi lisho ukuthi inani elihle lenzwa yokushisa kwamanzi liyancipha ngemva kokukhuphuka kwamanzi. Inzwa yokushisa kwamanzi esetshenziswa ezimotweni ine-coefficient yezinga lokushisa elibi.
