Umphuculi wenombolo ye-Cetane ukwabizwa ngokuba yi-diesel cetane number improver
Inombolo yeCetane yedizili sesona salathisi sepropathi ye-anti-knock yeoli ye-diesel.
Into eyenzeka kumphezulu wokunkqonkqozwa kwe-injini ye-diesel iyafana naleyo ye-injini yepetroli, kodwa unobangela wokunkqonkqoza wahlukile.
Nangona zombini ukuqhushumba kwavela kukutsha okuzenzekelayo kwepetroli, unobangela wokuqhushumba kwe-injini ye-diesel yinto echaseneyo ne-injini yepetroli, kuba i-diesel ayilulanga ukutsha okuzenzekelayo, ukuqala kokutsha okuzenzekelayo, ukuqokelelwa kwepetroli kwi-cylinder okubangelwa kakhulu.
Ke ngoko, inani le-cetane ledizili likwamele indalo yedizili.
Inombolo yecetane yi-100 n-cetane.Ukuba i-knock resistance ye-oyile ethile iyafana naleyo ye-fuel eqhelekileyo equlethe i-52% ye-n-cetane, inani le-cetane yeoli ngama-52.
Ukusetyenziswa kwamafutha edizili aphezulu, ukufana kwe-injini ye-diesel yokutsha, amandla aphezulu ashushu, ukonga amafutha.
Ngokuqhelekileyo, iinjini ze-diesel ezikhawulezayo ngesantya se-1000 RPM zisebenzisa i-diesel elula kunye nexabiso le-cetane le-45-50, ngelixa iinjini ze-diesel eziphakathi kunye nezantsi ngesantya esingaphantsi kwe-1000 RPM zingasebenzisa idizili enzima enexabiso le-cetane le-35. -49.
