A first blow-by pipe communicates the downstream side of the throttle valve located downstream of the supercharger with a ventilation case formed in the head cover of the engine, and a first blow-by pipe connects the ventilation case and the bypass valve. 2 blow-by pipes, and a flow rate control means for restricting only the flow from the bypass pipe to the ventilation case, and the bypass valve is configured to control the flow rate upstream of the supercharger when the pressure downstream of the throttle valve is positive. and a second blow-by pipe, and when the pressure on the downstream side of the throttle valve is a negative pressure greater than a predetermined value, the bypass pipe is brought into communication, and the bypass pipe and the second blow-by pipe are brought into communication with each other. Forced ventilation system for supercharged engines. 2. Utility model registration claim 1, characterized in that the flow rate control means is a pressure transmission valve mechanism having a check valve and an orifice that prevents flow from the bypass pipe to the ventilation case. forced ventilation system.
