    摘要： A method is provided to diagnose a failure of an OPCJ valve of an internal combustion engine. The OPCJ valve is located in an auxiliary line connecting an engine lubrication line to at least an oil jet for squirting lubricating oil from the engine lubrication line towards a piston surface. The method provides for monitoring the pressure variation in the engine lubrication line due to a switching signal sent to the OPCJ valve.

    摘要： Methods for diagnosing a fault of an oil piston cooling jets valve of an internal combustion engine are provided. A method includes sensing a pressure value in a main oil gallery and checking whether the oil piston cooling jets valve is commanded in a state for opening a communication between the main oil gallery and an auxiliary oil gallery or in a state for closing the communication. A pressure value in the auxiliary oil gallery is checked to as to whether it exceeds a predetermined threshold value thereof, above which a jet nozzle of the auxiliary oil gallery automatically opens. A fault of the valve is identified if the pressure value in the main oil gallery exceeds the predetermined threshold value by a predetermined quantity and if a pressure value in the auxiliary oil gallery is different than expected on a basis of the state of the valve.

    摘要： A method is provided to operate an electrically driven OPCJ valve of an internal combustion engine that includes, but is not limited to cyclically performing a control method able to generate an opening request for the OPCJ valve, of opening (which includes, but is not limited to keeping opened the OPCJ valve), when the control method generates an opening request, and of closing (which includes, but is not limited to or keeping closed the OPCJ valve), when the control method does not generate an opening request. The control method comprises the steps of determining a value of a control parameter related to an engine torque, and of generating an opening request for the OPCJ valve, if the control parameter value exceeds a threshold value of the control parameter.

    摘要： A system includes a temperature determination module and a flow determination module. The temperature determination module determines an engine coolant temperature based on input received from an engine coolant temperature sensor and determines an engine material temperature based on input received from an engine material temperature sensor. The engine coolant temperature is a temperature of coolant in an engine, and the engine material temperature is a temperature of at least one of an engine block and a cylinder head. The flow determination module selectively determines coolant flow through the engine based on the engine coolant temperature and the engine material temperature.

    摘要： A method of monitoring an engine coolant system includes modeling the total energy stored within an engine coolant. If an actual temperature of the engine coolant is below a minimum target temperature, the modeled total energy stored within the energy coolant is compared to a maximum stored energy limit to determine if sufficient energy exists within the engine coolant to heat the engine coolant to a temperature equal to or greater than the minimum target temperature. The engine coolant system fails the diagnostic check when the modeled total energy stored within the energy coolant is greater than the maximum stored energy limit, and the minimum target temperature has not been reached.
