The invention relates to a method for controlling the oil pressure of an oil pump (40, 140) in a combustion engine (100). The combustion engine (100) comprises a crankcase (11) and a separator (14, 114) for separating oil present in a blow-by gas from the crankcase (11). The method comprises the step (201) of providing oil pressure demand for a set of different engine operation conditions, the oil pressure demand defining the theoretical required oil pressure of the oil pump (40, 140); the step (203) of controlling the oil pressure of the oil pump (40, 140) based on the oil pressure demand for at least one engine operation condition in the set of different engine operation conditions; the step (205) of driving the separator (14, 114) using oil from the oil pump (40, 140), the oil being pressurized based on the oil pressure demand.
A method for controlling oil pressure of an oil pump in a combustion engine, the combustion engine comprising a crankcase and a separator for separating oil present in a blow-by gas from the crankcase, the method comprising providing an oil pressure demand for a set of different engine operation conditions, the oil pressure demand defining a theoretical required oil pressure of the oil pump, wherein the theoretical required oil pressure is determined based on at least an amount of blow-by gases in the crankcase;
An oil pressure arrangement for a combustion engine comprising:
