| Sumario: | The motored engine friction torque test has been developed for the purpose of evaluating various additive formulations. Difference in frictional behavior using different additive chemistries were observed and the importance of the additive chemistry for fuel economy was indicated. Sequence VID engine testing was conducted and the correlation between the motored engine friction torque test and Sequence VID was considered. Excellent correlation between the motored friction torque tests and Sequence VID FEI 1 was demonstrated. However, excellent correlation with FEI 2 was not observed at any conditions of the motored engine friction torque test. Also, the motored engine friction torque test correlates with vehicle fuel consumption with JC08H and 10.15 modes on a chassis dynamometer test. |
