Engine friction optimisation using Virtual Dynamics

Engine friction reduction has always been of interest to improve efficiency and fuel economy. Automotive industry pay an increased particular attention to engine friction in the recent years to achieve the aggressive CO2 emission targets.
Software & Testing Solutions`s advanced multibody dynamics simulation software Virtual Dynamics is used to optimize the engine friction in components level. The method includes calibration of multi-body simulation models using system level measurement or database information and split the friction shares of the engine subsystems and components using physical friction modeling approaches. Parametric studies of components are carried out to investigate their influence on friction without the necessity to acquire and operate costly hardware.
