Fuel Evaporation Control; Washer Fluid - Porsche 911 CARRERA - 2003 Manual

Fuel Evaporation Control
Fuel
tank
venting
The evaporation chamber and the carbon canis-
ter prevent fuel from escaping to the atmos-
phere at extreme high outside temperatures,
when driving abruptly around curves and when
the car is parked at an incline or in any other
nonlevel position.
Vapor control
system and storage
When the fuel tank is filled, vapors are collected
in the evaporation chamber by a vent line lead-
ing 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.
Washer Fluid
The reservoir, with a blue screw cap, is in the
luggage compartment, to the rear left.
