Hidea HDF6 - Blowby Gas Reburning System

Power unit system
Blowby gas reburning system
A blowby gas reburning system is adopted to be respectful with the environment.
To reburn the blowby gases, this engine separates oil from the blowby gases in two labyrinths.
First, oil is separated from the blowby gases in the cylinder block labyrinth, and then in the intake
silencer labyrinth.
The oil separated from the blowby gases flows back to the crankcase, and the blowby gases sepa-
rated from the oil are sucked into the combustion chamber.
