Vim li cas cov roj lubricating tau nplaim taws?
Raws li lub zog sib xyaw ua ke ntawm kev nyiam muaj zog, cov khoom zoo li cov roj cav yuav tsis hlawv ntawm chav tsev kub. Ib yam khoom xws li cov roj cav yuav tsum yog raug rau qhov kub siab tshaj 150 ° C, rau nws tsim cov vapors txaus kom ignite nyob rau hauv qhov chaw ignition.
