Oil management system for an internal combustion engine, and a method for oil management of such an engine

A method for oil management of an internal combustion engine that includes a crankcase, the method comprising:

• determining a predetermined oil level in the crankcase of the internal combustion engine;
• providing a first container and a second container in fluid communication with each other, the first container including a first quantity of oil, the second container configured to temporarily store a predetermined second quantity of oil;
• providing a pump that is configured to operate in a first mode and a second mode, oil being transferable respectively to and from the second container in the first and second modes;
• providing a flow measuring unit configured to measure an oil flow to or from the second container when the pump is operating, the flow measuring unit including a first sensor configured to detect a predetermined first oil level between a minimum oil level and a maximum oil level in the second container;
• when the pump is operating in the first mode of operation,
• determining, by the flow measuring unit, a first time interval required for the oil level in the second container to reach the predetermined first oil level,
• calculating, by the flow measuring unit, the oil flow to the second container using the predetermined first oil level and the first time interval,
• consecutively calculating, by the flow measuring unit, a second time interval required for the oil level in the second container to reach the maximum oil level, and
• one or more of switching off the pump, and switching the pump into the second mode of operation, by the flow measuring unit, when the oil level reaches the maximum oil level;
• and
• delivering the predetermined second quantity of oil from the second container to the crankcase of the internal combustion engine depending on the measured oil flow.
