Parametric Studies on Critical Parameters of Variable Displacement Oil Pump for Automotive Application

Abstract:

Currently, the fixed-displacement oil pump supplies the oil for lubrication. Most of the time, these oil pump consumes more power and deliver significantly higher oil pressure than the required. This leads to the excess power consumption of the engine to run the pump; in turn lower fuel efficiency and higher CO₂ emissions. In this study, the concept of variable delivery oil pump is taken and critical design parameters that affect the oil flow rate are identified and studies are carried out to arrive at the correlation. From the results it can be observed both positive and negative correlation exists between the different critical parameters and the oil flow rate.
