Inkcazo yokuxinana kwedizili kunye nokubaluleka kwayo
Ukuxinana kwedizili yeyona parameter yomzimba yokulinganisa umgangatho kunye nokusebenza kwamafutha edizili. Uxinaniso lubhekisa kubunzima beyunithi nganye yesibaso sedizili kwaye budla ngokubonakaliswa ngeekhilogram ngecubic meter nganye (kg/m³). Kwimizi-mveliso yeekhemikhali kunye namandla, ukuxinana kwe-diesel kunempembelelo ngqo kwiinkalo ezininzi zokusebenza kwamafutha, ukugcinwa kunye nokuthutha.
Uluhlu olusemgangathweni lwe-diesel density
Ngokwesiqhelo, ukuxinana kwamafutha edizili kuqhelekile kuluhlu lwama-800 ukuya kuma-900 kg/m³, kodwa olu luhlu lunokwahluka ngokuxhomekeke kwinkqubo yokuvelisa, imvelaphi yemathiriyeli ekrwada kunye nokwakheka kwezongezo. Umzekelo, uxinano lwamafutha edizili asemgangathweni (ongu-0. 0 amafutha edizili) luqhele ukuba malunga nama-835 kg/m³, ngelixa uxinano lwamafutha edizili acutshungulwe ngokukodwa lunokwahluka kancinci. Ngoko ke, xa ukhetha i-diesel fuel, ukwazi uluhlu lwazo lokuxinana kunokuncedisa ukugweba umgangatho kunye nokufaneleka kwayo.
Isiphumo soxinaniso lwe-diesel ekusebenzeni kokutsha
Uxinaniso lwe-diesel lunempembelelo ebalulekileyo ekusebenzeni kakuhle kokutsha. Ngokuqhelekileyo, i-diesel fuel enoxinano oluphezulu ikhupha amandla amaninzi ngexesha lokutsha ngenxa yokuba iqulethe ii-hydrocarbons ezininzi kwiyunithi nganye. Ukuxinana okugqithisileyo kunokukhokelela ekuncipheni komgangatho wokutshizwa kwee-injector, ngaloo ndlela kuchaphazela ukusebenza kakuhle kokutsha kunye nemigangatho yokukhupha. Ke ngoko, ingxinano yedizili kufuneka ilawulwe ngokuchanekileyo kukhetho lwamafutha kunye noyilo lwe-injini ukuze kuqinisekiswe ukutsha okugqibeleleyo kunye nokukhutshwa okuncinci kongcoliseko.
Impembelelo yobushushu be-ambient kwi-diesel density
Uxinzelelo lwamafutha e-diesel luyatshintsha kunye nobushushu. Ngokuqhelekileyo, ukuxinana kwamafutha edizili kuncipha kancinci njengoko ubushushu bunyuka. Oku kubangelwa yimpembelelo yokwanda kwe-thermal yee-molecule ze-diesel kumaqondo aphezulu. Enyanisweni, umphumo wokushisa kwi-density ye-diesel fuel kufuneka uqwalaselwe ngokucophelela, ngokukodwa ngexesha lokugcinwa kunye nokuthutha i-diesel fuel, apho ukulawulwa kokushisa okungafanelekanga kunokukhokelela kwiimpazamo ze-volumetric. Ngesi sizathu, iinkampani zeoyile zihlala zilungisa ukuxinana kwamafutha edizili kubushushu ukuqinisekisa ukuchaneka kweendawo ezahlukeneyo.
Indlela yokulinganisa ubuninzi bedizili
Umlinganiselo wobuninzi bedizili udla ngokuqhutywa kusetyenziswa i-densitometer okanye ibhotile ethile yomxhuzulane. Umsebenzisi uya kuqala agalele isampulu yedizili kwisixhobo sokulinganisa kwaye aqinisekise ukuba ubushushu besampulu buzinzile. Ixabiso loxinaniso lwepetroli yedizili lunokuthi emva koko luthathwe kufundo lwe-densitometer okanye ifomula yebhotile ethile yomxhuzulane. Le nkqubo, nangona ibonakala ilula, idinga iqondo elithile lobuchule kwicala lomqhubi ukuqinisekisa ukuchaneka nokuthembeka komlinganiselo.
Ubudlelwane phakathi koxinano lwedizili kunye neendawo zokusetyenziswa
Iimeko ezahlukeneyo zokusetyenziswa zineemfuno ezahlukeneyo zoxinaniso lwedizili. Ngokomzekelo, i-fuel ye-diesel ephantsi yobushushu esetyenziswa kwimimandla ebandayo iya kuhlengahlengiswa ukuxinana kwayo xa kuthelekiswa ne-fuel ye-diesel eqhelekileyo ukukhusela ukuqina phantsi kweemeko eziphantsi kobushushu. Ngakolunye uhlangothi, i-diesel fuel esetyenziswe kwiinjini zokusebenza eziphezulu zifuna ukulingana phakathi koxinano kunye nokusebenza kakuhle kokutsha ukuze kuqinisekiswe ukuphuma kwamandla kunye noqoqosho lwamafutha. Ngoko ke, ukuqonda ubuninzi be-diesel fuel kunye nokuyikhetha ngokweemfuno zesicelo sisitshixo sokuqinisekisa ukusebenza kakuhle kunye nokwandisa ubomi benkonzo yezixhobo.
Ukuqukumbela
Ubuninzi bedizili sesinye sezona zalathisi ezibalulekileyo zomgangatho wedizili kunye nokusebenza. Ngokuqonda uluhlu olusemgangathweni, izinto ezichaphazelayo kunye neendlela zokulinganisa ubuninzi bedizili, unokukhetha ngcono iimveliso zedizili ezifanelekileyo kwiimeko ezahlukeneyo zesicelo. Oku akuncedi nje ekuphuculeni ukusebenza kakuhle kwamafutha, kodwa kunciphisa ukukhutshwa kwezinto ezikhutshwayo kunye nokukhusela okusingqongileyo. Uxinaniso lwe-diesel luya kuqhubeka ludlala indima ebalulekileyo kwizicelo zedizili zexesha elizayo kunye nophando.
