Fuel Evaporation Control; Washer Fluid - Porsche CARRERA GT-2004 Manual

Fuel Evaporation Control

Fuel tank venting
The evaporation chamber and the carbon canister
prevent fuel vapors from escaping to the atmo-
sphere at extreme high outside temperatures,
when driving abruptly around curves and when the
car is parked at an incline or in any other non-level
position.
Vapor control system and storage
When the fuel tank is filled, vapors are collected in
the evaporation chamber by a vent line leading the
vapors to the carbon canister where they are
stored as long as the engine does not run.
Purge system
When the engine is running, the fuel vapors from
the canister will be mixed with fresh air from the
ambient air of the canister. This mixture will be
directed to the intake air housing by the tank vent
line, mixed with the intake air and burned during
normal combustion.
