IKit yeNozzle ye-Injector entsha M0027p155 yezitofu zeFuel A2c59507596 A2c53381618 1660000q1w

(1) Ngokutsho kwendawo yokusabalalisa, i-carbon deposits kwimigodi ye-jet ingahlulwa ibe ngamacandelo amathathu: i-carbon deposits ekuphumeni, i-carbon deposits yamaqhekeza amakhulu kwiipores kunye nekhabhoni kwindawo yangaphakathi yodonga lwama-pores. Ubume bokubekwa kwekhabhoni kwindawo yokuphuma buqhelekile kwaye busasazwe ngokulinganayo kwi-outlet kwimilo ye-arc.

Iidiphozithi zekhabhoni zibonisa imimandla eyahlukeneyo ye-compact kunye ne-fluffy. Amasuntswana amakhulu kwipore ane-carbon accumulation encinci kunye nokumila okungaqhelekanga. Ikhabhoni eludongeni lwangaphakathi lomngxuma lukhokelela ekwandeni koburhabaxa eludongeni kunye nokuqokelelwa kwekhabhoni encinci, kwaye icala lokuphuma lomngxuma libonakala ngakumbi kunecala lokungena.

(2) Ngokuskena i-electron microscopy, kunokufumaneka ukuba i-carbon ephantsi i-spherical, iincinci ze-spherical zicwangciswe ngokusondeleyo, isakhiwo sinzima, ubukhulu buvela kwii-microns ezimbalwa ukuya kwishumi le-microns; Ikhabhoni engaphezulu idityaniswe ngokupheleleyo, isakhiwo sidibene, kwaye umphezulu ucocekile kwaye usicaba; Iidiphozithi zekhabhoni zenziwa ikakhulu zii-athom ze-C kunye ne-O, ezinenani elincinci le-atom ze-Si, Fe, K, Mo, Cl kunye ne-Cr. Imithombo ephambili yamacandelo e-carbon deposition yimveliso yokutsha kwe-diesel, ioli kunye nezongezo zayo kunye neengqungquthela zetsimbi.

(3) Izikhundla ezahlukeneyo, iimilo kunye nobukhulu be-jet hole i-carbon deposition ineempembelelo ezahlukeneyo ekuhambeni komngxuma kunye neempawu zokutshiza.
