Vuzani Imfundo Yekharity Yakho Yokufaka Isilwane
Ukufaka Isilwane Ngendlela Yokufaka, Ukufaka Ngendlela Yokufaka Ngokwezinye, Nakwezinye Zokufaka Isilwane: Ukulandela Uhlobo Lwesiphumo Ngokwezinye Zokufaka Isilwane
Indlela okuyisikwe ngayo umsindo kumoto yisibonelo sokuthi sifuna iphampu ephinde yini futhi iyisebenza ngaphansi kwemiphumela yini. Amamotolo emsindo othile okusebenzisa ukuthumela umsindo kuyasebenzisa amaphampu atholakala ngokuphathelene ne-30 ku-85 psi ukuze abhale umsindo kumkhumbi wokuvula, okulawulwa ngokucophelela ngumkhiqizo wemoto. Amamotolo okwesikhathi esidliweyo okusebenzisa i-carburetor ayisebenzisa amaphampu atholakala ngokuphathelene ne-4 ku-7 psi, okuyisibonelo sokuthi kuyasebenzisa isibonelo se-venturi ukuze kwenziwe ukuchazwa kahle kwehloko nomsindo. Uma kubhekwa emamotoleni emsindo yokuqondisa, ikakhulu emamotoleni amasha okwesibonelo se-common rail, izinto ziyabuka kakhulu ngezimiphumela ezihamba ku-15,000 ku-30,000 psi kuphela ukuze kwenziwe ukuvula ngokugcina, okusho ukuthi izinkampani zokuthumela emiphumelweni ephakeme ziyadingeka. Uma iphampu engafanele ibhalwe, abadrayivha bangaqonda izinkinga zokuthi umsindo uyavula, ukudla kungafanele kususwa, ukukhula kungafanele, noma kufanele kakhulu ukuthi umkhumbi wabo uyadlula ngokuphela kumhlaba.
Ukufaka kwe-Fuel Pump ngaphakathi vs. ngaphandle kwe-Tank: Ukufaka, Ukuchitha Kuhlangothi, Nokudala Kwakho
Ukubeka kwe-fuel pump kuyaphatha kakhulu ukuchitha kuhlangothi, ubunzima bomshado, ubudala bokusebenza, nokubanzi kokufaka:
| Isici | Ukufaka kwe-Pump ngaphakathi kwe-Tank | Ukufaka kwe-Pump ngaphandle kwe-Tank |
|---|---|---|
| Ukulamula | Kwakhiwe ngaphakathi kwe-fuel (ukuchitha kuhlangothi kuhle kakhulu) | Kuchithwa ngohlobo lwehlobo (kuphela kwe-overheating) |
| Indlela yamahlaba | Kusebenza ngokushesha kakhulu | Kubonakala ukuthi kushesha kakhulu |
| Usuku lwesibophelelo | 100,000+ miles (okujwayelekile) | 50,000–70,000 miles (okujwayelekile) |
| Ukufakwa | Kudinga ukususa isitanki noma ukufinyelela ngokuphakama phansi | Kufinyelela ngaphansi kwesikhumba sokubeka |
Amaphumpa esitankini ayisebenza kakhulu emazwini amasha ngokuthi aqondiswe ngokuphelele ukuchitha, ukugcina umbono wokushusha, nokuthembekile. Amaphumpa esilayini ayisisekelo esihle kubantu abasebenzisa izithombe zezindaba zemvelo, izindaba zokuphepha nezinkundla zokuphakama, noma izindlela ezinokuthi amafueli ashiywe ngokungafanele ngokuphakama kakhulu kwezindaba zokuhamba noma ukuphakama.
Determine Precise Fuel Flow and Pressure Requirements
Ukubala Ukuvimba Kwamafueli Okudingekayo (LPH/GPH) Ngokusebenzisa i-BSFC Nokuhlanganisa I-Horsepower
Ukufumana isibonelo sokuphakamisa amafuel esifanayo sivame kusukela ngokuzazi ukuthi indawo yokuqala iyayidinga ngokwezimali zokubhala. Lokhu kuyaphakama ngokubhala kwe-Brake Specific Fuel Consumption, okungathi kusho ngokufuphi ngokuthi i-BSFC, okuyisibonelo sokuthi indawo yokuqala iyayihle kangakanani xa kubhekwa ngamapound we-fuel ngamahpower e-hour. Amathuluzi asebenza kahle asebenzisa i-gasoline ayasebenza phakade kuhlanganisa phakade kuma-0.50 ku-0.60 lbs/HP/hr. Kodwa izinto ziyagcina xa sizihlalisele izinkotho zezithuthi zokugcina noma amathuluzi athengisiwe ngokwesibonelo sokuphakamisa kakhulu—lezi ziyadinga kahle kuma-0.60 noma kungenye. Ukuzazi ukuthi kuzoba yini ukubhala kwe-volume, kufuneka sifunde i-specific gravity yefuel esebenzisa. Kuma-gasoline asebenza kahle, lo nomhla uyisibonelo sokuthi kuhlanganisa kuma-0.737. Lokhu kukhomba kanjani ukubhala: gijima i-horsepower eyidinga kanye ne-BSFC, emva koko yahlula lokho ngokuthi i-specific gravity yefuel ukuze ufumele ukubhala okuncane kwe-pounds per hour. Emva kwalokho, ukuguqula kwi-liters per hour kuyakwazi kahle.
Umsebenzi wokuhlukanisa, injini yomthwalo wokuzimela engu-400 HP nesibonelo se-BSFC = 0.55 ne-gasoline (SG = 0.737): (400 × 0.55) ÷ 0.737 ≈ 298 lbs/hr ≈ ~404 LPH
Emva koko yisebenzisa izilungiselelo eziphambili:
- Faka isikhundla sesihlukahluka se-15–20% ukubuyeza ukuphakanyiswa kwemithwalo emaphiltara, emalayini, nemaregulateri
- Phakanya umkhawulo ngama-~30% kuma-E85 (ngoba yisikhundla sesihlukahluka sokuphakanyiswa kwe-energy kanye nokuphakanyiswa kwe-stoichiometric air/fuel ratio)
Amathuluzi amaningi okuhamba kahle noma amathuluzi okuhamba kahle akhuluma kahle ayadinga ukuthi kubhekeke kwi-500–1,000+ LPH.
Ukuchaza iindlela zokubala imithwalo: Ukubhala ngokuvula vs. Ukusebenza kwenqubo ekhuluma kahle
Izilungiselelo zemathuluzi zokubhala ziyincwadi ezimbili zokubala imithwalo ozinikwe ziyabonakala kuzo izimo zokusebenza ezihlukene:
- Imithwalo yokuvula : Umkhawulo omkhulu kuzo zonke izinto ezingavuli (isibonelo, “100 LPH @ 0 PSI”) — kuyasebenza kuphela njengokubhala ngokulinganisa
- Imithwalo yokusebenza kwenqubo ukuhambisa okuphakanyisiweyo ngokuphakanyiswa kwezinhlobo zokuhambisa, izihluzi, nezinkampani zokulungisa ukuphakanyiswa
| Uhlobo Lwesimo | Isilinganiso Sekuphakanyiswa Kwenkampani | Ingeno EYenzekelayo | Iphondo Lokungahlinzeka |
|---|---|---|---|
| Kwakhiwe Ngokusebenzisa Ikarbureta | 4–7 PSI | ±1 PSI | Ukuvula kwesikhumba sokufa noma ukungafani kwezinye izinto |
| Ukubhala Kwesikhumba Sokufa Ngokusebenzisa I-Port | 40–65 PSI | ±5 PSI | Ukuphakanyiswa okubi, ukuzimisela, noma izikhathi zokufana noma zokubeka kwezinye izinto |
| Uhlu lwenqanawe oluzenzakalelayo | 1,500–3,000 PSI | ±200 PSI | Ukuphakanyiswa okungakwaziwa kahle, ukuthabatha kwemithambo, noma ukugqitywa kwemithambo yokuqala |
Iziqu zokuphakanyiswa ezisuselwa kuzo zibiza ngokushesha izinkinga zokusebenza: isikhathi sokuphakanyiswa esincane sibiza izimo zokufana (ukuphakanyiswa okungakwaziwa kahle, ukuphakanyiswa kabefore, ukugqitywa kwemithambo yokuqala); isikhathi sokuphakanyiswa esikhulu sibiza ukuthenga kwezinye izinto futhi sibiza ukuthabatha kwezinye izinto. Qiniseka ukusebenza ngokusebenzisa i-OBD-II live data—hlengahlengisa “Isikhathi Sokuphakanyiswa Kwesikhumba Sokuthenga” noma “Isikhathi Sokuphakanyiswa Kwesikhumba Sokuthenga Ngempela” ngaphansi kwesikhathi sokuphakanyiswa kahle futhi ngaphansi kwesikhathi sokuphakanyiswa esisuselwa kuzo.
