FUEL TANK (Continued)
An evaporation control system restricts fuel evapo-
ration into the atmosphere and reduces unburned
hydrocarbons. Vapors from the fuel tank are collected
in a charcoal filled canister. The vapors are held in
the canister until the engine is operating. When the
engine is running, the vapors are drawn through the
intake manifold into the combustion chambers.
The ORVR control valve manages the flow of vapor
during refueling. It also controls maximum fuel vol-
ume of the fuel tank (Fig. 29).
