摘要： An evaporative emissions (EVAP) system for an engine of a vehicle includes an ion sensing system configured to measure a fuel/air ratio (FAR) within cylinders of the engine and a controller configured to, during an engine cold start period, perform open-loop lambda control of the engine including obtaining, from the ion sensing system, the measured FAR within the cylinders of the engine, comparing the measured FAR within the cylinders of the engine to a target FAR within cylinders of the engine, and based on the comparing, adjusting operation of at least one of the EVAP system and fuel injectors of the engine to maintain a stoichiometric operation of the engine, wherein the use of the ion sensing system for open-loop lambda control of the engine eliminates the need for a hydrocarbon (HC) sensor in the EVAP system.

摘要： An evaporative emissions (EVAP) control system for a vehicle includes a purge pump configured to pump fuel vapor to a direct injection (DI) engine of the vehicle via a vapor line and a purge valve and a hydrocarbon (HC) sensor disposed configured to measure an amount of HC in the fuel vapor. The system also includes a controller configured to detect an HC vapor supply condition indicative of an operating condition of the Di engine where engine vacuum is less than an appropriate level for delivering the fuel vapor to the DI engine via the vapor line; and in response to detecting the HC vapor supply condition, controlling at least one of the purge pump and the purge valve, based on the measured amount of HC, to deliver a desired amount of fuel vapor to the DI engine to decrease particulate matter (PM) produced by the DI engine.

摘要： An evaporative emissions (EVAP) control system for a vehicle includes a purge pump configured to pump fuel vapor to an engine of the vehicle via a vapor line and a purge valve. The system includes a hydrocarbon (HC) sensor disposed in the vapor line and configured to measure an amount of HC in the fuel vapor pumped by the purge pump to the engine via the vapor line. A controller is configured to: detect an imminent cold start of the engine and, in response to the detecting, perform the cold start of the engine by controlling at least one of the purge pump and the purge valve, based on the measured amount of HC, to deliver a desired amount of fuel vapor to the engine, which decreases HC emissions by the engine.

摘要： A liquid collection device for removing a liquid from a catalyst brick is provided and includes a containment vessel having an inner volume and a receiver supported by the containment vessel and in fluid communication with the inner volume, whereby the receiver supports the catalyst brick relative to the containment vessel. The collection device further includes a vacuum source spaced apart from the receiver and in fluid communication with the inner volume. The vacuum source exerts a fluid force on the catalyst brick to draw the liquid from the catalyst brick and into the inner volume.

摘要： A catalyst degradation detection method for use with a zero ceria catalyst. The method uses techniques to measure transient responses to engine control events of upstream and downstream sensors to determine catalyst degradation and performance. By measuring transient behavior, the method can determine catalyst degradation and performance based on the limited oxygen storage of precious metal catalysts that do not include added ceria or other materials with high oxygen capture rates.

摘要： An evaporative emissions (EVAP) control system for a vehicle includes a purge pump configured to pump fuel vapor trapped in a vapor canister to an engine of the vehicle via a vapor line when engine vacuum is less than an appropriate level for delivering fuel vapor to the engine, the fuel vapor resulting from evaporation of a liquid fuel stored in a fuel tank of the engine. The EVAP control system includes a hydrocarbon (HC) sensor disposed in the vapor line and configured to measure an amount of HC in the fuel vapor pumped by the purge pump to the engine via the vapor line. The EVAP control system also includes a controller configured to, based on the measured amount of MC, control at least one of the purge pump and a purge valve to deliver a desired amount of fuel vapor to the engine.
