| 发明名称 | Engine efficiency system for a vehicle and method of operating an engine efficiency system | ||
| 摘要 | An engine efficiency system for a vehicle includes an electromechanically operated oil distribution device disposed proximate an oil environment of the vehicle. Also included is a current detection system for detecting a current change rate of the electromechanically operated oil distribution device, wherein the current change rate corresponds to a viscosity of an oil disposed in the oil environment of the vehicle. Further included is at least one efficiency device activated over a range of the viscosity of the oil. | ||
