A method for an engine, comprising adjusting a transmission ratio of a magnetic transmission in response to a temperature of an engine, wherein the magnetic transmission connects a water pump to a shaft of an oil mist separator of the engine.
A method for an engine, comprising in response to a cooling request of an engine, adjusting a magnetic transmission connecting a water pump and a shaft of an oil separator of the engine.
An engine system, comprising:
- a crankcase;
- a crankcase venting system coupled to the crankcase;
- an oil mist separator in the crankcase venting system, wherein the oil mist separator includes an electric drive and a shaft driven by the electric drive;
- a cooling circuit including a water pump;
- a magnetic transmission coupled to the shaft, the magnetic transmission connecting the shaft to the water pump;
- and
- a controller configured with computer readable instructions stored on non-transitory memory for adjusting a transmission ratio of the magnetic transmission in response to a temperature of the engine.
