I-LPG (igesi eliwuketshezi lukaphethiloli)
I-LPG iyingxube ewuketshezi ye-propane, i-butane nezinye izithasiselo, ezakheka ngesikhathi sokucutshungulwa kwe-petroleum feedstock. Esimweni sokuqala, ayinawo umbala, ukunambitheka kanye nephunga, ngakho-ke, i-ejenti yephunga yengezwa engxubeni - iphunga (into enephunga elibonakalayo). I-LPG ayinabo ubuthi, kodwa ayingeni emoyeni futhi inomphumela onobuthi omaphakathi. Esimeni segesi, inzima kunomoya, futhi esimweni samanzi, ilula kunamanzi. Ngakho-ke, izimoto ze-LPG akufanele zishiywe emagaraji angaphansi komhlaba, njengoba uma kwenzeka kuvuza, i-LPG izohlala ihlezi ezindaweni eziphansi kakhulu futhi isuse umoya ophefumulayo.
I-LPG ikhiqizwa ngenkathi kusetshenzwa ama-petroleum feedstocks. Iyancibilikiswa ngokupholisa noma ngokucindezela ukunciphisa ivolumu yayo izikhathi ezingama-260. I-LPG isetshenziswa njengenye indlela eshibhile kunophethiloli njengoba izakhiwo zayo zifana kakhulu. Unguphethiloli omuhle kakhulu onesilinganiso se-octane cishe esingu-101-111. Ezimweni zethu, ingxube ebizwa ngokuthi yi-LPG yasebusika (60% P no-40% B) kanye nenhlanganisela ye-LPG yasehlobo (40% P no-60% B), i.e. ushintsho kuzilinganiso ezihambisanayo ze-propane ne-butane.

Ukuveza okuqondile (inani lekhalori, inani lekhalori, njll.), I- "Theoretical Equivalence Coefficient" ichazwa ngevolumu kaphethiloli equkethe inani elithile lamandla elilingana nenani lekhalori likaphethiloli. Bese kuthi “isilinganiso sangempela sokulingana” phakathi kokusetshenziswa kwenjini sinqunywe, esingakuqhathanisa ngangokunokwenzeka.

Masithathe imoto ene-mileage kagesi emaphakathi engaba ngamalitha ayi-7. Ngemuva kwalokho (sicabangela ukwakheka kwenhlanganisela yasehlobo kanye ne-coefficient yokulingana, sithola ifomula:
(ukusetshenziswa kukaphethiloli * (40% propane ngokulingana kuka-1,27 + 60% butane ngokulingana kuka-1,11)) = Ukusetshenziswa kwe-LPG
7 * (0,4 * 1,27 + 0,6 * 1,11) = 7 * 1,174 = 8,218 l / 100 km v lete
7 * (0,6 * 1,27 + 0,4 * 1,11) = 7 * 1,206 = 8,442 l / 100 km ebusika
Ngakho-ke, umehluko kuzimo ezifanayo zesimo sezulu uzoba njalo 0,224/ 100 km. Kuze kube manje, zonke lezi zibalo zethiyori, kodwa zichaza iqiniso lokuthi ukusetshenziswa kuzokhula kuphela ngenxa yokupholisa. Yiqiniso, nabo banesibopho sokwanda okwengeziwe kokusetshenziswa - amathayi ebusika, ukuqala kwebusika, ukukhanya okwengeziwe, iqhwa emgwaqeni, mhlawumbe ngisho nokuzwa okuncane komlenze, njll.
