[3] REED VALVE

The reed valve is provided at the confluence of
exhaust gas after passing the EGR valve, and intake air.
It operates by the pressure difference between inside of
the crankcase and the atmosphere, and prevents
backflow of the mixture of exhaust gas and intake air
generated by the piston and valves. It is used as the
secondary air
countermeasure against exhaust gas of four-cycle
engines.
