LOW-TEMPERATURE ENGINE OIL PUMPABILITY IN FULL-SCALE ENGINES

Pumpability data were obtained using thirteen ASTM Pumpability Reference Oils in seven full-scale engines. Borderline pumping conditions were determined for each oil-engine combination investigated. The mode of pumping failure in the engines and the times required to lubricate the rocker arms were also obtained. The results indicate that substantial differences in pumpability exist among both engines and oils. Possible reasons for these differences are suggested, based on engine oil pump inlet system characteristics and the viscometric properties of the oils. /GMRL/
