Izinkinga Zomjovo Wamafutha kanye Nokuxazulula Izinkinga
Izijovo zezinaliti… Ezinjinini zesimanje, izijovo zezinaliti zisetshenziswa kakhulu ezinjinini zikaphethiloli, futhi ikakhulukazi ku-GDI (umjovo oqondile wegesi). Njengoba sixoxile ezihlokweni ezedlule, i-GDI i-atomize futhi ifake ama-athomu uphethiloli ngqo ekamelweni elivuthayo, phezu kwepiston. Ngenxa yokucushwa kwe-pintal, amadiphozi ekhabhoni enza i-pintal cone, ephazamisa iphethini yesifutho. Njengoba i-buildup ikhula, ukusabalalisa okungalingani kwejethi kuzoholela ekushiseni okungalingani okuzokhula kube ukungaqhubi kahle noma ukuhlengezela...futhi ngokunokwenzeka kungadala indawo eshisayo ku-piston noma, ezimweni ezimbi kakhulu, kuncibilikise imbobo ku-piston. Ngeshwa, lesi simo siyalungiswa (mhlawumbe) ngokusebenzisa isithasiselo sikaphethiloli "sokuhlanza", ngokushayela isistimu yomjovo ngemishini ekhethekile nesixazululo esigxilile, noma ukukhipha ama-injector ukuze asetshenziswe noma ashintshwe.
Ama-injection anemigodi eminingi ama-injection amakhulu asetshenziswa ezinjinini zikadizili. Inkinga enkulu ebhekene nanoma iyiphi injini yesimanje kadizili izinga nokuhlanzeka kukaphethiloli. Njengoba kushiwo ngaphambili, izinhlelo zesimanje ze-Common Rail zifinyelela izingcindezi ezifika ku-30,000 psi. Ukuze kuzuzwe izingcindezi eziphakeme kangaka, ukubekezelelana kwangaphakathi kuqinile kakhulu kunezinguqulo zangaphambilini zama-nozzles (okunye ukubekezelelana kokujikeleza kungama-microns angu-2). Njengoba uphethiloli kuwukuphela kokugcoba ama-injection ngakho-ke ama-injection, uphethiloli ohlanzekile uyadingeka. Ngisho noma ushintsha izihlungi ngesikhathi esifanele, ingxenye yenkinga ukunikezwa kukaphethiloli... cishe wonke amathangi angaphansi komhlaba anokungcola (ukungcola, amanzi noma ulwelwe) okubekwe phansi ethangini. UNGALINGE ugcwalise uphethiloli uma ubona iloli likaphethiloli lilethela uphethiloli (ngoba isivinini samafutha angenayo sithinta into engaphakathi ethangini) - inkinga ukuthi iveni lingase livele lihambe kanti awulibonanga!!
Amanzi kuphethiloli ayinkinga enkulu njengoba amanzi enyusa izinga lokubila likaphethiloli, kodwa nakakhulu athinta kabi ukuthambisa kukaphethiloli okubalulekile...ikakhulukazi njengoba isibabule esasikhona njengesithambiso sasuswa ngomthetho we-EPA. . Amanzi akuphethiloli ayimbangela eyinhloko yokungasebenzi kwethiphu lomjovo. Uma unamathange akho okugcina ngaphezu komhlaba, i-condensate eyakha ngaphakathi kwethangi ngaphezu kolayini kaphethiloli (ikakhulukazi emazingeni okushisa ashintsha ngokushesha) izokwakha amaconsi futhi iye ngqo phansi ethangini. Ukugcina la mathangi okugcina egcwele kuzonciphisa le nkinga… Ukuxhuma kabusha ithange lokugcina kuyanconywa uma unesiphakeli samandla adonsela phansi ngaphansi kwethangi.
Uphethiloli ongcolile noma we-algae nawo uyinkinga ngezinhlelo zesimanje zomfutho ophezulu. Ungakwazi ukubona uma ukungcola kuyinkinga ekuhlolweni... izithombe ezimbalwa zinamathiselwe encwadini.
Enye inkinga esibhekene nayo eNyakatho Melika izinga langempela noma ukuvutha kukaphethiloli uqobo. Inombolo ye-cetane iyisilinganiso salokhu. Uphethiloli we-diesel uqukethe izingxenye ezingaphezu kwe-100 ezithinta inombolo ye-cetane (efana nenombolo ye-octane kaphethiloli).
ENyakatho Melika, inani elincane le-cetane lingama-40... e-Europe, ubuncane bungama-51. Kubi kakhulu kunalokho okuzwakalayo ngoba yisikali se-logarithmic. Okuwukuphela kwento engenziwa ukusebenzisa isithasiselo ukuthuthukisa kokubili inombolo ye-cetane kanye nokuthambisa. Atholakala kalula… vele uqhelelane nalabo abanotshwala…kufanele asetshenziswe kuphela njengendlela yokugcina lapho ulayini wamafutha uqandisiwe noma upharafini ukhona. Utshwala buzobhubhisa ukuthambisa kukaphethiloli, kubangele ukuba iphampu noma ama-injection abambe.
