Cetane tus lej txhim kho kuj tseem hu ua diesel cetane tus lej txhim kho
Cetane naj npawb ntawm diesel yog lub ntsiab Performance index ntawm anti-knock cuab yeej ntawm diesel roj.
Qhov tshwm sim saum npoo ntawm lub cav diesel cav zoo ib yam li cov roj av cav, tab sis qhov ua rau lub khob yog qhov sib txawv.
Txawm hais tias ob qho tib si detonation tshwm sim los ntawm qhov tshwm sim ntawm cov roj spontaneous combustion, qhov ua rau ntawm diesel cav detonation tsuas yog qhov ntxeev ntawm roj av cav, vim hais tias diesel tsis yooj yim rau spontaneous combustion, pib ntawm spontaneous combustion, roj tsub zuj zuj nyob rau hauv lub tog raj kheej los ntawm ntau dhau lawm.
Yog li ntawd, tus naj npawb ntawm cetane ntawm diesel kuj sawv cev rau naturalness ntawm diesel.
Tus naj npawb ntawm cetane yog 100 n-cetane.Yog hais tias lub khob tsis kam ntawm qee cov roj yog tib yam li cov qauv roj uas muaj 52% n-cetane, tus naj npawb ntawm cov roj yog 52.
Kev siv cov roj diesel siab, diesel cav combustion uniformity, siab thermal zog, roj txuag.
Feem ntau hais lus, kev kub ceev diesel xyaw nrog qhov ceev ntawm 1000 RPM siv lub teeb diesel nrog tus nqi cetane ntawm 45-50, thaum nruab nrab thiab qis ceev diesel xyaw nrog qhov ceev ntawm tsawg dua 1000 RPM tuaj yeem siv hnyav diesel nrog tus nqi cetane ntawm 35. -49.
