Hyundai Santa Fe: Evaporative Emission Control System / Description and operation
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 the canister filled with charcoal
and 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 use vacuum in intake manifold to move
it.
Schematic Diagram
Canister
Canister is filled with charcoal and absorbs evaporated vapor in fuel tank.
The gathered fuel vapor in canister is drawn into the intake manifold by the
ECM/PCM when appropriate conditions are set...

Replacement
•
Put on gloves to prevent hand injuries.
•
When removing with a flat-tip screwdriver or remover, wrap protective
tape around the tools to prevent damage to components...
Description
Continuous Variable Valve Timing (CVVT) system advances or retards the valve
timing of the intake and exhaust valve in accordance with the ECM control signal
which is calculated by the engine speed and load.
By controlling CVVT, the valve over-lap or under-lap occurs, which makes better
fuel economy and reduces exhaust gases (NOx, HC) and improves engine performance
through reduction of pumping loss, internal EGR effect, improvement of combustion
stability, improvement of volumetric efficiency, and increase of expansion work...
