  • Patent number: 11852056
    Abstract: The present invention relates to a method for controlling lubrication of a connecting rod bearing of an internal combustion engine arrangement. The method comprises the steps of controlling an inlet valve to be maintained in the closed position during a movement of the reciprocating piston from the top dead center during an intake stroke for a predetermined number of crank angle degrees; and positioning the inlet valve in the open position when the reciprocating piston has traveled the predetermined number of crank angle degrees from the top dead center, wherein lubricating medium is provided to the connecting rod bearing within a predetermined time period before the inlet valve is arranged in the open position.
