Evaporative Emission
Control System prevents fuel vapor stored in fuel tank from vaporizing
into the atmosphere. When the fuel evaporates in the fuel tank, the vapor
passes through vent hoses or tubes to canister filled with charcoal. The
canister temporarily holds the vapor in the charcoal. If ECM determines to
draw the gathered vapor into the combustion chambers during certain
operating conditions, it will vacuum into intake manifold.
