I-LPG iye yaziswa kwimarike njengepetroli ecocekileyo. Emva kokusebenza endleleni iminyaka emininzi kangaka, ingaba icocekile ngokwenene? I-LPG inokuba yipetroli ecocekileyo. Ukusebenza kwayo kakuhle kokukhupha umbane sisizathu esibalulekileyo.
Iinkcukacha zezi zilandelayo:
Xa kuthelekiswa nenjini yepetroli, ukukhutshwa kwe-CO kuya kuncitshiswa (kungabi ngaphantsi njengenjini yedizili).
Akukho kukhutshwa kwee-hydrocarbons ezinzima.
Ukukhutshwa okuncinci kwezinto ezinobuthi ezifana ne-benzene kunye ne-butadiene.
Ukuqala okubandayo nokuphuma komoya okuphantsi.
Izinzile ngakumbi kunenjini yepetroli ngokubhekiselele ekugcineni ukukhutshwa okungcono komoya. Igesi enobungozi ye-LPG ayizukwanda ngenxa yokuguqulwa kwenjini kunye nokuguga kwayo. Ngenxa yokuvalwa kakuhle kwenkqubo yepetroli, akukho ngxaki yokufuma kunye nokuvuza kweoyile.
Ngenxa yezizathu ezahlukeneyo, i-LPG ayisetyenziswanga endaweni yepetroli yexesha elizayo. Indima yayo ithatyathelwe indawo yigesi yendalo ekhuphisana nedizili kunye nedizili yokwenziwa. Ngenxa yoko, iinjini ze-LPG ezintsonkothileyo azizange ziphuhliswe. Kwiminyaka elishumi edlulileyo, iinjini zepetroli kunye nokukhutshwa kwazo kuphuculwe kakhulu. Ke ngoko, ipetroli ye-LPG, eyayithathwa njengeneengenelo ezininzi kwixesha elidlulileyo, ingakumbi ukukhutshwa kwayo kwe-CO ephantsi, ayikhathalelwa.
Enyanisweni, zonke iinjini ze-LPG ziguqulwa kwiinjini zepetroli. Uyilo lobunjineli alusebenzisi ithuba lokukhupha i-LPG okuncinci okunokwenzeka. Ezi injini kunye neenkqubo zokulawula ipetroli azilungiselelwanga olu phawu lutsha, kwaye ziseneempawu zokusebenza kakubi kokuqala, ukusetyenziswa kwepetroli okuphezulu kunye nokukhupha okukhulu kweegesi eziyingozi. Ezi mpawu zokubonakalisa kunye nokukhupha igesi zihlala zahluka ngokuxhomekeke kwinjini kunye nokudibanisa kokuguqulwa. Isixhobo sokuguqula i-LPG se-elektroniki siya kubonelela ngokukhupha igesi okuncinci kunye nokusebenza kakuhle kokutsha. Kodwa akukho datha yaneleyo yokuqinisekisa eli bango. Injini eyenziwe ngokuguqulwa koomatshini yodwa ayifikeleli kwinqanaba elifanelekileyo lokukhupha igesi okuncinci kwe-LPG. Kububulumko ukucela idatha yokukhupha igesi kumthengisi xa uthenga isithuthi se-LPG sangaphakathi. Ngelishwa, nangona kunjalo, akukho nto intsha ukuba inqanaba lokukhupha i-CO kwizithuthi ezintsha ze-LPG li-2-4%. Njengomgangatho osisiseko, kuyamkeleka ukuba uxinzelelo lokukhupha igesi lwe-CO yenjini ye-LPG phantsi kwesimo esizinzileyo kufuneka lube ngaphantsi kwe-1%.
Ukukhutshwa kwe-LPG kuxhomekeke kakhulu kwimeko yokusebenza kwenjini. Ukususela kubuthathaka bokukhutshwa kwe-LPG ukuya kumlinganiselo womxube womoya neoyile, kunokubonwa ukuba xa umlinganiselo womxube ungaphezulu kowomoya, umxholo we-carbon monoxide uyanda ngokuthe ngqo. Sifanele sinikele ingqalelo enkulu kulungiso kunye nokugcinwa kwemeko yokusebenza eyiyo yenjini ukuze kubekho ukukhutshwa okuphantsi, kodwa akufuneki sixhomekeke kuphela kolu hlengahlengiso kunye nokugcinwa.
