Full-Load Mode Crankcase Ventilation Function

WARNING: This page is about a different car, the 2018 Infiniti Q60. However, it is still accessible from the selected car via links, so may be relevant.

Blow-by gas is sucked into the air intake pipe from the oil separator.

The full-load operation vent line heater element is installed to the ventilation line connected to the air filter downstream and heats excessive gas according to a signal from ECM when ambient air temperature becomes less than 7 deg.C (44.6 deg.F).

This prevents damage to engine caused by frozen excessive gas.
