Motoarele diesel alimenteaz\u0103 o gam\u0103 larg\u0103 de vehicule \u0219i utilaje, de la camioane de marf\u0103 \u0219i utilaje agricole p\u00e2n\u0103 la generatoare \u0219i utilaje industriale.<\/p>\n

Acestea sunt apreciate pentru puterea, durabilitatea \u0219i eficien\u021ba lor \u00een ceea ce prive\u0219te consumul de combustibil, potrivit ScienceDaily<\/a>.<\/p>\n

Exist\u0103 \u00eens\u0103 \u0219i un dezavantaj. Gazele de e\u0219apament ale motoarelor diesel reprezint\u0103 o surs\u0103 major\u0103 de poluare a aerului, eliber\u00e2nd gaze \u0219i particule care pot d\u0103una s\u0103n\u0103t\u0103\u021bii umane.<\/p>\n

Cercet\u0103torii afirm\u0103 c\u0103 o solu\u021bie surprinz\u0103tor de simpl\u0103 ar putea ajuta la rezolvarea acestei probleme. Conform unei analize, amestecarea unor cantit\u0103\u021bi mici de ap\u0103 \u00een motorin\u0103 ar putea reduce dramatic emisiile nocive. \u00cen acela\u0219i timp, men\u021bine \u0219i chiar \u00eembun\u0103t\u0103\u021be\u0219te, performan\u021ba motorului.<\/p>\n

Echipa de cercetare a examinat dovezile privind tehnologia emulsiei de ap\u0103 \u00een motorin\u0103 (WiDE), o abordare care amestec\u0103 pic\u0103turi minuscule de ap\u0103 \u00een motorin\u0103. Concluziile sugereaz\u0103 c\u0103 aceast\u0103 modificare relativ simpl\u0103 a combustibilului ar putea oferi o modalitate practic\u0103 de a face motoarele diesel mai ecologice, f\u0103r\u0103 a fi necesare reproiect\u0103ri costisitoare.<\/p>\n

De ce poluarea cu motorin\u0103 reprezint\u0103 o provocare<\/h2>\n

\u00cen ciuda numeroaselor avantaje, motoarele diesel produc cantit\u0103\u021bi semnificative de poluan\u021bi. Printre cei mai \u00eengrijor\u0103tori se num\u0103r\u0103 oxizii de azot, denumi\u021bi adesea NOx, \u0219i particulele \u00een suspensie.<\/p>\n

Oxizii de azot contribuie la formarea smogului \u0219i pot irita pl\u0103m\u00e2nii, \u00een timp ce particulele fine constau \u00een particule microscopice care pot fi inhalate ad\u00e2nc \u00een sistemul respirator. Expunerea la ace\u0219ti poluan\u021bi a fost asociat\u0103 cu afec\u021biuni respiratorii \u0219i alte probleme de s\u0103n\u0103tate. Emisiile de motorin\u0103 joac\u0103, de asemenea, un rol \u00een impactul asupra mediului legat de schimb\u0103rile climatice.<\/p>\n

Vehiculele moderne cu motor diesel se bazeaz\u0103 adesea pe tehnologii precum convertizoarele catalitice \u0219i filtrele de particule pentru a reduce poluarea. De\u0219i eficiente, aceste sisteme pot spori at\u00e2t complexitatea, c\u00e2t \u0219i costul motoarelor.<\/p>\n

Cercet\u0103torii sugereaz\u0103 c\u0103 tehnologia emulsiei de ap\u0103 \u00een motorin\u0103 ar putea oferi o abordare complementar\u0103 mai simpl\u0103.<\/p>\n

Cum func\u021bioneaz\u0103 combustibilul de tip \u201eap\u0103 \u00een motorin\u0103\u201d<\/h2>\n

La prima vedere, ad\u0103ugarea de ap\u0103 \u00een motorin\u0103 poate p\u0103rea contraintuitiv\u0103. Apa \u0219i combustibilul sunt de obicei considerate o combina\u021bie nefavorabil\u0103 \u00een interiorul unui motor.<\/p>\n

Cheia const\u0103 \u00een faptul c\u0103 apa nu este pur \u0219i simplu turnat\u0103 \u00een rezervorul de combustibil. \u00cen schimb, pic\u0103turi minuscule de ap\u0103 sunt dispersate uniform \u00een motorin\u0103 cu ajutorul unor compu\u0219i cunoscu\u021bi sub numele de surfactan\u021bi. Surfactan\u021bii ac\u021bioneaz\u0103 ca stabilizatori. Ace\u0219tia ajut\u0103 apa s\u0103 r\u0103m\u00e2n\u0103 \u00een suspensie \u00een combustibil \u0219i \u00eempiedic\u00e2nd separarea amestecului. Emulsiile formulate corespunz\u0103tor pot r\u0103m\u00e2ne stabile p\u00e2n\u0103 la \u0219aizeci de zile.<\/p>\n

C\u00e2nd combustibilul este injectat \u00een motor \u0219i se aprinde, se \u00eent\u00e2mpl\u0103 ceva neobi\u0219nuit. Apa captat\u0103 se transform\u0103 rapid \u00een vapori. Aceast\u0103 expansiune brusc\u0103 creeaz\u0103 ceea ce cercet\u0103torii numesc o \u201emicro-explozie\u201d, care fragmenteaz\u0103 combustibilul \u00een pic\u0103turi mai fine \u0219i \u00eembun\u0103t\u0103\u021be\u0219te modul \u00een care acesta se amestec\u0103 cu aerul.<\/p>\n

O amestecare mai bun\u0103 duce la o ardere mai complet\u0103. \u00cen acela\u0219i timp, prezen\u021ba apei contribuie la sc\u0103derea temperaturilor maxime de ardere din interiorul motorului. Aceast\u0103 combina\u021bie ofer\u0103 dou\u0103 beneficii importante. Temperaturile mai sc\u0103zute reduc formarea oxizilor de azot, \u00een timp ce o combustie mai complet\u0103 reduce emisiile de funingine \u0219i de particule.<\/p>\n

Pentru industriile care continu\u0103 s\u0103 depind\u0103 de energia pe baz\u0103 de motorin\u0103, un amestec simplu de ap\u0103 \u0219i combustibil ar putea oferi o cale nea\u0219teptat de eficient\u0103 c\u0103tre un aer mai curat.<\/p>\n","protected":false},"excerpt":{"rendered":"
