Ukuqaliswa kwe-carbon commutator yokugqibela

Ukusetyenziswa kweekhompawundi zekhabhoni kunye nekhabhoni ukuvelisa ii-DC motor commutators kwaphononongwa zizazinzulu zaseJamani kwasekuqaleni kweMfazwe Yehlabathi II.
Emva kokoyiswa kweJamani, izazinzulu zaseJamani zabanjwa ngumkhosi wase-US kwaye zangena ukuqhubeka nophando lwabo.
Kodwa xa i-brushless motor yaphuma, yafumana ingqalelo kubomi bayo obude. Umsebenzi wophando kwiukuphelisa abahambisi bekhabhoniilibaziseke kangangexesha elithile.
Emva kokuba isithuthi samkele isixhobo se-EFI, ipompo yepetroli ayikwazi ukusebenzisa i-brushless motor ngenxa yokulinganiselwa komthamo. Ipompo yepetroli yemoto ye-EFI intywiliselwa kumafutha ukuze isebenze, kwaye i-petroli eveliswa ngoku kwaye ithengiswa kwilizwe lam inomxholo wesulfure ophantsi. Iphezulu, indawo yokusebenza yobhedu, ngaphezu kokutshiswa kweentlantsi zombane xa iibrashi zekhabhoni zitshintshwa, kuya kukhawulezisa ukunxiba ngenxa yokubola kweekhemikhali zesulfure. Ngaphaya koko, ukuze kuhlangatyezwane nokungafumaneki ngokwaneleyo kwepetroli kwimarike yamafutha exesha elizayo kunye nokulawula ukungcoliseka kombhobho weenqwelo-mafutha, urhulumente waseTshayina uqalisile ukuthengisa i-ethanol petroli eyonakalisayo kwisiseko sokulinga. Uvavanyo oludibeneyo yi-Chinese Academy of Sciences kunye neYunivesithi yaseTsinghua lubonisa ukuba izongezo zangoku kwipetroli ye-ethanol ziya kubangela ukubola okunamandla kwi-commutator yensimbi, okukhokelela ekunciphiseni okubonakalayo kubomi benkonzo yemoto, kwaye kukhokelela ngokuthe ngqo kwiintsilelo ezahlukeneyo ze-injini.

Ngeli nqanaba, i-European Union kunye namanye amazwe sele eqalisile ukwenza imigangatho efanelekileyo, kwaye sele eqalisile ukukhuthaza nokusebenzisa iimpompo zamafutha e-elektroniki.ukuphelisa abahambisi bekhabhonikwiimpompo zabo zokuthatha indawo yobhedu kunye nezinye ii-commutators zetsimbi ukwandisa ubomi benkonzo yeempompo zamafutha. Ixesha lokwamkelwa ngokubanzi kweukuphelisa abahambisi bekhabhonikwiimpompo zamafutha emoto ziye zafika.
