Fig. 13 Evaporative emission control system.:

The evaporative emission control system, Fig. 13, is designed to lead fuel vapor emitted from the fuel tank into the engine crankcase, where it is mixed with blow-by gasses and drawn into the intake manifold for combustion. This system consists of a charcoal canister, evaporator valve, intake manifold, vapor separator tank, purge control valve, roll over and float valve, two-way valve and tubes connecting these parts.
