AIR INDUCTION SYSTEM

AIR INJECTION
The air induction system burns unburned
exhaust
air(secondary air) into the exhaust port,
reducing the emission of hydrocarbons.
When there is negative pressure at the
exhaust port, the reed valve opens,
allowing secondary air to flow into the
exhaust port. The required temperature for
burning the unburned exhaust gases is
approximately 600 to 700º C.
