    摘要: This disclosure relates a water pump, a system for cooling internal combustion engine components including a water pump, and a method for operating an internal combustion engine including a water pump. The water pump, system and method provide protection of the pump impeller during dry pump operation, such as when a watercraft engine is started while the watercraft is out of water, by dispensing fluid from a reservoir to the pump's impeller chamber. The fluid enters the chamber via a controllable flow path and interacts with the impeller and chamber walls to cool and lubricate the impeller.

    摘要: A method and system for identifying or determining degradation in performance of an engine cooling subsystem having an electric motor for powering a fan in a locomotive is provided. The method allows for monitoring a signal indicative of an electrical imbalance in one or more phases in the fan motor of the cooling subsystem, and for adjusting the value of the monitored signal for deviations from an estimated nominal phase signal value due to predetermined external variables so as to generate an adjusted phase signal value. The method further allows for comparing the value of the adjusted phase signal value against the nominal phase signal value to determine the performance of the cooling subsystem.
