  • Hydrocarbon retaining and purging system
    Patent number: 8161733
    Abstract: Methods and systems are provided for operating an engine having a hydrocarbon retaining system and an emission control device coupled to an engine exhaust, the engine exhaust comprising a venturi. One example method comprises, during a storing condition, routing exhaust gas through the venturi without generating a venturi action, and then to the hydrocarbon retaining system, while bypassing the emission control device, to store hydrocarbons in the hydrocarbon retaining system, and during a purging condition, routing exhaust gas through the venturi while generating venturi action, then to the emission control device, and then to the hydrocarbon retaining system, to purge stored hydrocarbons, wherein a flow of purged hydrocarbons is drawn back to the venturi via venturi action.

  • METHOD AND SYSTEM FOR FUEL VAPOR CONTROL
    Publication number: 20120055452
    Abstract: A method and system for fuel vapor control in a hybrid vehicle (HEV). The HEV fuel vapor recovery system includes a fuel tank isolation valve, which is normally closed to isolate storage of refueling from storage of diurnal vapors. The method for fuel vapor control includes selectively actuating the fuel tank isolation valve during interrelated routines for refueling, fuel vapor purging, and emission system leak detection diagnostics to improve regulation of pressure and vacuum the HEV fuel vapor recovery system.

  • Methods and Systems for Variable Displacement Engine Control
    Publication number: 20110265771
    Abstract: Methods and systems are provided for selecting a group of cylinders for selective deactivation, in a variable displacement engine system, based at least on a regeneration state of an exhaust catalyst. The position of one or more valves and throttles may be adjusted based on the selective deactivation to reduce back-flow through the disabled cylinders while also maintaining conditions of a downstream exhaust catalyst. Pre-ignition and knock detection windows and thresholds may also be adjusted based on the deactivation to improve the efficiency of knock and pre-ignition detection.

  • Method and System for Fuel Vapor Control
    Publication number: 20110265768
    Abstract: Methods and systems are provided for operating a fuel vapor recovery system having a fuel tank isolation valve coupled between a fuel tank and a canister. Fuel vapors are purged from the fuel tank to a canister buffer over a plurality of purge pulses. The pulses are adjusted based on the buffer capacity, a purge flow rate, and a fuel tank pressure to improve control of canister loading and reduce air-to-fuel ratio disturbances.
