Because of the low viscosity of emulsion, valve type orifice was used in emulsion motor and the volumetric efficiency was ensued.
Experimental research on measuring the output of piston pump based on suction volumetric efficiency
clearance volumetric efficiency
volumetric efficiency
volumetric efficiency of mine air
Because of the lower volumetric efficiency, the initial throttle openings for the start and idling of the LPG engine are larger than those of the gasoline engine.
The hydraulic fluid viscosity, the volumetric efficiency and the hydraulic system working efficiency drops, divulging increases, even causes the mechanical device to be unable the normal work.
