The invention discloses a variable-mode valve drying system and belongs to the field of engine vale driving, cylinder stopping and auxiliary braking. The variable-mode valve driving system comprises an exhaust braking cam, an exhaust drive cam, a gas inlet drive cam and a gas inlet braking cam, wherein all the cams drive a valve through push rods, rocker arms and the like. The variable-mode valve driving system further comprises an exhaust braking fulcrum assembly, an exhaust drive fulcrum assembly, a gas inlet drive fulcrum assembly and a gas inlet braking fulcrum assembly which are arranged between all the cams and correspond valve assemblies or all the cams and corresponding valve bridge assemblies. Modes of four-stroke driving, two-stroke braking, cylinder stopping and the like are achieved by controlling the states of all the fulcrums, and the purposes of low oil consumption, low emission and efficient braking are achieved. The variable-mode valve driving system is compact in structure, high in reliability and low in cost.
