  • Turbocharged engine purge flow monitor diagnostic
    Patent number: 9062637
    Abstract: A method is provided for testing the evaporative emission system of a vehicle having a forced induction engine. The method includes controlling a vacuum bypass valve and a purge flow control valve to create the necessary conditions to perform the testing of the evaporative emission system. The method determines whether an evaporative system integrity monitor switch is open after a timer is initiated and the vacuum bypass valve is opened.
    Type: Grant

  • Turbocharged engine canister system and diagnostic method
    Patent number: 8924133
    Abstract: An evaporative emission control system for a turbocharged engine. The system includes a fuel vapor canister in fluid communication with an intake manifold of the engine, a purge valve positioned between the intake manifold and the canister, a bypass valve positioned between the purge valve and the canister and connected to the atmosphere, and an evaporative system integrity monitor operable to seal the canister from the atmosphere when the engine is off. In operation, the monitor is closed so as to seal the canister from the atmosphere, the purge valve is closed so as to isolate the intake manifold from the canister, and the bypass valve is opened so as to connect the canister to the atmosphere. Proper operation of the monitor is determined if the monitor toggles from closed to open when a vacuum in the fuel vapor canister reaches a predetermined level.
