Khumbula ipetroli enelothe?
Ngenxa yempilo yethu kunye nangenxa ye-catalytic converters, eyaba sinyanzelo kuzo zonke iimoto ezintsha ukususela ngo-1993, ukusetyenziswa kunye nokuthengiswa kwepetroli kwakungavumelekanga.
Nangona kunjalo, oku akuzange kuthintele iimoto eziyisebenzisayo ukuba zingasasebenzi, njengoko esi songezo satshintshwa ngokubandakanya ezinye izongezo zokuqinisekisa umphumo ofanayo.
ULuís Serrano, umphandi kwi-ADAI, uMbutho woPhuhliso lwe-Industrial AerodynamicsAbavelisi bamafutha 'banyanzelwa' ukuba baphuhlise olunye uhlobo lwezongezo ezenziweyo, nto leyo eyenza ukuba kube lula ukuqinisekisa ukugcinwa kwenani le-octane ephezulu ngaphandle kokubhenela kwilothe. Oku kuvumela ukusetyenziswa kwee-catalysts, ukugcina amandla okusebenzisa amazinga aphezulu oxinzelelo, kubalulekile ukugcina ukusebenza kakuhle kweenjini, kwaye, ngenxa yoko, ukunciphisa ukusetyenziswa. Lo mzekelo wekhonkrithi ubonisa indima ebalulekileyo eyenziwa uphando kunye nophuhliso lwamafutha kunye nezongezelelo - kwaye iyaqhubeka idlala - ekuhlangabezaneni neenjongo zokukhutshwa kweenjini zokutsha zangaphakathi.
Ke ngoko, into yokuqala ebalulekileyo ukukhuthaza ukuncitshiswa kokukhutshwa kukunyusa ingeniso ye-injini. Ukwazi ukuba i-injini yokutsha inomlinganiselo wokusebenza ophakathi kwama-25%, oku kuthetha ukuba okukhona usezantsi umgangatho wepetroli, kokukhona ucikizeko oluphantsi lwe-injini lunikezelayo kwaye kokukhona ukukhutshwa okukhulu kweegesi okubangelwa kukutshiswa. Ngokuchasene noko, i-fuel efanelekileyo ivumela ukusebenza kakuhle, njengoko ukunyuka kwentsebenzo kufunyenwe ngamanani amancinci aphethiloli, okukhuthaza ukunciphisa ukukhutshwa kokukhutshwa ngokubonga kwisigaba esisebenzayo sokutshisa.
Uphononongo olwenziwa licandelo lemichiza ye-BASF ("I-Eco-Efficiency Study for Diesel Additives, Novemba 2009) ibonisa oku: izongezo ezikhoyo kumafutha ziyinxalenye ebalulekileyo ekuqinisekiseni ukusebenza kakuhle kweenjini, kungafuneki isixa esikhulu sezinto ezongezelelweyo. ukufikelela kwiziphumo ezizinzileyo nezihlala zihleli ngexesha lokusetyenziswa kwesithuthi.
Symbiosis phakathi abavelisi
Xa uthelekisa ukusebenza kwedizili eyongeziweyo kunye neyongezelelekileyo, lo msebenzi liqela laseJamani likhankanya ukuba into ebizwa ngokuba "yi-diesel elula" ayinakunceda ukusebenza kakuhle kwe-thermodynamic, nayo ibe nefuthe elibi kubomi obude bamacandelo.ULuís Serrano, umphandi kwi-ADAI, uMbutho woPhuhliso lwe-Industrial AerodynamicsIinjini zangoku zenziwe ngezinto ezinokunyamezelana kakhulu, ngoko ke kubalulekile ukuba amafutha aqinisekise ukucoceka okuhambelanayo kunye nokukhuthaza ukupholisa okufunekayo kumacandelo ahlukeneyo enkqubo yokutofa, kwaye iqinisekisa ukukhuselwa kwi-oxidation kunye nokuthotywa kwezinto kunye nokuqinisekisa ukuba ukuthanjiswa kwamacandelo.
Ngoko ke, "uphuhliso lweenjini kunye neenkqubo zokutshisa ezihambelanayo zinyanzelise ukuphuhliswa kwamafutha aneempawu ezingcono, ezikwazi ukuqinisekisa ukusebenza ngokufanelekileyo kwezi nkqubo kunye neenjini ezifanelekileyo", uqhubeka lo mphandi.
Ii-injini zangoku zokutofa ngokuthe ngqo, apho isibaso simelana noxinzelelo oluphezulu kakhulu kunye namanqanaba obushushu, zifuna ii-injection kunye neepompo ezisebenza ngokufanelekileyo, kodwa zikwanovelwano ngakumbi kwiimpawu kunye neepropathi zamafutha asetyenziswayo.
Oku kuthethelela imfuno ye-symbiosis phakathi kophuhliso lwamalungu kunye neenjini kunye neenkqubo zokuvelisa amafutha ezintsonkothileyo, ukomeleza uphando lwezongezo ezikwaziyo ukusabela kwiimfuno ezibekwe ngabavelisi beenjini.
ULuís Serrano, umphandi kwi-ADAI, uMbutho woPhuhliso lwe-Industrial AerodynamicsUkufumana umbono obambekayo wophuhliso lwamafutha kunye nezongezelelo zabo kunye nokubaluleka kwazo ekuthembekeni kweenjini (...) ukuba i-fuel ukusuka kwiminyaka eyi-15 okanye engama-20 eyadlulayo yayisetyenziswa kwi-injini yangoku, ngexesha elifutshane. sebenzisa, loo njini iya kuba neengxaki ezinzulu zokusebenza.
Gxininisa kwi-eco-efficiency
Ngeethagethi zokukhutshwa ziqiniswa ngakumbi nangakumbi kwicala labavelisi beemoto - ukusukela ngo-2021, iimpawu zibophelelekile ukuthoba inqanaba eliphakathi lokukhutshwa kweCO2 kwinqanawa ukuya kwi-95 g/km, phantsi kwesohlwayo sezohlwayo ezinzima -, Inkunkuma kunye nesuntswana. ugcino kunye neenkqubo zonyango ziya zisiba nzima kwaye zinovakalelo.
Kwaye zibiza kakhulu.
Ngokuchanekileyo ukuqinisekisa ukusebenza ngokufanelekileyo kobu buchwepheshe (abavelisi beemoto kufuneka baqinisekise ukuya kuthi ga kwiikhilomitha ezili-160 lamawaka, ngokwengcebiso yaseYurophu) kukuba amafutha athatha indima ebaluleke kakhulu kwaye ahlala ephuhliswa kwaye ekhuthazwa umsebenzi wawo.
SILANDELE KU-YOUTUBE Bhalisa kwitshaneli yethu
Kulo msebenzi we-BASF, i-fuel additive ifezekisa iziphumo ezingcono ngokubhekiselele kumandla kwaye, ngenxa yoko, nangokwemiqathango yokukhutshwa.
Kodwa, okubaluleke ngaphezu kwesi sigqibo, kukubonisa indlela ukusebenza kakuhle kunye nokusebenza kwepetroli eyongezelelweyo enkulu njengoko injini ixhomekeke kwimithwalo ephezulu. Eyomeleza ukubaluleka kwamafutha athembekileyo kwizithuthi zorhwebo okanye iimodeli ezikwaziyo ukusebenza ngamandla.
ULuís Serrano, umphandi kwi-ADAI, uMbutho woPhuhliso lwe-Industrial AerodynamicsUphando kunye nophuhliso lwamafutha kunye nezongezo ziqhubeka zidlala indima ebaluleke kakhulu ekuhlangabezaneni neenjongo zokukhutshwa kweenjini zokutsha zangaphakathi. Ngokomzekelo, ngokwemigaqo yedizili, ukuncitshiswa kwesulfure kucacile, nto leyo ephelisa ukukhutshwa kweekhompawundi zesulfure, ezingcolisa kakhulu kwaye ziphunyezwe ngokupheleleyo ngabavelisi bamafutha. I-sulfure yinto eqhelekileyo ekubunjweni kweoli yesiseko (engcolileyo) kwaye ibonakala rhoqo kakhulu kwi-diesel, ngoko ke kuyimfuneko ukususa le nto kwinkqubo yokucoca. Ngale ndlela kwakunokwenzeka ukuphelisa le nto, ukuqinisekisa ukuba ukukhutshwa kongcoliseko kwinqanaba leekhompawundi zesulfure ngoku kushiyekileyo ngokugqibeleleyo. Okwangoku, olu hlobo lokukhutshwa kwezinto ezikhutshwayo aluseyongxaki.
