Abstract
A crank case ventilation system for ventilation of blow by gases from an internal combustion engine includes a crank case ventilation pipe connectable with a first end to the internal combustion engine for receiving blow by gases from the internal combustion engine and with a second end to an air inlet pipe provided upstream of a turbo and/or a super charger, where the second end of the crank case ventilation pipe is provided for delivering blow by gases to the air inlet. At least a part of at least one heat pipe is provided inside the crank case ventilation pipe, where the at least one heat pipe is provided for transporting compressed air to an inlet downstream the turbo and/or the super charger.

A crank case ventilation system for ventilation of blow by gases from an internal combustion engine, the system comprising a crank case ventilation pipe connectable with a first end to the internal combustion engine for receiving blow by gases from the internal combustion engine and with a second end to an air inlet pipe provided upstream of a turbo and/or a super charger, where the second end of the crank case ventilation pipe is provided for delivering blow by gases to the air inlet, wherein at least a part of at least one heat pipe is provided inside the crank case ventilation pipe, where the at least one heat pipe is provided for transporting compressed air to an inlet downstream the turbo and/or the super charger.
A method for ventilating blow by gases from a crank case of an internal combustion engine, comprising:
- providing a crank case ventilation pipe for receiving blow by gases from the crank case of the internal combustion engine,
- transporting the blow by gases from the crank case to an inlet of the internal combustion engine, where the inlet is provided upstream of a turbo and/or a super charger,
- providing at least a part of one heat pipe inside the crank case ventilation pipe, where the at least one heat pipe is provided for transporting compressed air to an inlet downstream of the turbo and/or the super charger.
