    摘要: Systems and methods are disclosed for adjusting oil pressure supplied to engine components. In one example approach, a method for controlling oil flow in an engine comprises adjusting oil pressure supplied to the engine based on engine acceleration. For example, engine acceleration may be used to predict future engine lubrication requirements so that oil pressure adjustments may be scheduled accordingly.

    摘要: Methods and systems are provided for diagnosing each of a plurality of engine cooling system components including various valves and grill shutters. Each valve may be individually closed and opened for a specified duration, and corresponding changes in coolant temperature may be monitored. If all the components are functional, the various valves may be adjusted to stagnate coolant at the engine and expedite engine warm-up during a cold-start.
