    摘要: An oil circulating control system for an engine includes an engine speed module and a mode selection module. The engine speed module determines a speed of the engine. The mode selection module is configured to select a first pressure mode and a second pressure mode of an oil pump of the engine for the speed. The selection module selects one of the first pressure mode and the second pressure mode based on at least one mode request signal. The mode selection module signals a solenoid valve of a variable oil pressure circuit of the oil pump to transition to a first position when operating in the first pressure mode and to a second position when operating in the second pressure mode.

    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: 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 method is disclosed for managing the transition between a lean combustion mode and a rich combustion mode, or vice versa. After a regeneration demand, or at the end of the regeneration phase, the air mass flow is modified from a first set point to a new set point within a predetermined time depending on the engine conditions. An air mass percentage value is cyclically calculated and compared with a target value. When the target value is reached, the fuel path is then suddenly switched to compensate the torque change due to different combustion modes and to achieve the desired rich or lean condition.
