While fully-variable fan drives are proven and standard equipment on heavy-duty commercial vehicles (e.g. semi-trucks) as a means to reduce fuel consumption and noise, they are not standard on generator sets. Moreover, their effect on generator set operation has not been deeply studied. The goals of this study were to determine if a fully-variable fan drive cooling system could reduce fuel consumption and noise on a 100kW generator set and whether those results might be extrapolated to other generator sets.
