Evaporative Emissions: Overview




Evaporative Emissions

Overview

The EVAP (Evaporative Emission) system prevents hydrocarbon emissions from entering the atmosphere by storing fuel vapors and routing the vapors to the engine to be consumed during normal engine operation.

The EVAP (Evaporative Emission) system consists of:

- EVAP (Evaporative Emission) canister

- EVAP (Evaporative Emission) canister purge valve

- Dual check valve (2.0L GTDI (Gasoline Turbocharged Direct Injection) engine) (part of the canister purge valve)

- Vapor ejector (2.0L GTDI (Gasoline Turbocharged Direct Injection) engine) (part of the canister purge valve)

- Dust separator

- EVAP (Evaporative Emission) canister vent solenoid

- Fuel vapor tube assembly (includes the FTP (Fuel Tank Pressure) sensor)

- Easy Fuel(TM) (capless) fuel tank filler pipe.
