摘要： A vehicle engine system includes an internal combustion engine, an air induction system configured to supply intake air to the internal combustion engine, and an evaporative emissions control (EVAP) system is configured to selectively supply purge fuel vapor to the EHC for subsequent combustion and rapid heating to a predetermined catalyst light-off temperature. The system additionally includes a booster configured to charge the intake air, and an engine bypass conduit fluidly coupled between the booster and the exhaust aftertreatment system. When the internal combustion engine is off, the booster selectively supplies a flow of intake air through the engine bypass conduit to the exhaust aftertreatment system. The flow of intake air draws purge fuel vapor from the EVAP system into the exhaust aftertreatment system.

摘要： A method of diagnosing an operating condition of a short runner valve in an intake manifold of an internal combustion engine using an exhaust sensor in an exhaust manifold of the internal combustion engine. The short runner valve is commanded to an open position for a test period, it is resolved whether the test period has elapsed, and it is determined whether a sensed exhaust gas parameter has exceeded a threshold during the test period. A pass signal is issued if the sensed exhaust gas parameter has exceeded the threshold within the test period. Otherwise, a fail signal is issued if the sensed exhaust gas parameter has not exceeded the threshold within the test period.

摘要： A diagnostic method for an evaporative emission control system of an automotive vehicle determines functionality of one of a purge valve and/or a vacuum switch and valve assembly. The vacuum switch and valve assembly is located between a carbon canister and atmosphere and is either open or closed according to whether the system is in a high or low negative pressure condition. A controller determines if the vacuum switch and valve assembly is functioning properly according to the high or low negative pressure condition. The controller determines if the purge valve is functioning properly based on engine performance characteristics.

摘要： A diagnostic method and system includes a control valve configured to control an amount of air drawn into an evaporative emissions (EVAP) system through an air filter and a vapor canister, and a pressure sensor configured to measure pressure in the EVAP system. The system also includes a controller configured to detect an engine idle-to-off transition and, in response to detecting the engine idle-to-off transition: receive a first pressure from the pressure sensor, fully open a purge valve connected between the vapor canister and an intake port of an engine, fully close the control valve, monitor one or more second pressures received from the pressure sensor, and detect a malfunction of the EVAP system based on the first pressure, at least one of the one or more second pressures, and a diagnostic threshold.

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 HC, control at least one of the purge pump and a purge valve to deliver a desired amount of fuel vapor to the engine.

摘要： A boost purge ejector tee arrangement for a fuel vapor emissions system can include a boost purge ejector tee having a body that can define a first inlet port, a second inlet port and an outlet port. The first inlet port and the outlet port can be fluidly coupled along a first flow path. The body can define a second flow path from the second inlet port that can intersect the first flow path upstream of the outlet port. A nozzle can be positioned in the first flow path such that an outlet of the nozzle can be proximate the intersection of the second flow path with the first flow path. The boost purge ejector tee can be integrated into an air box that can be associated with an engine such that the outlet port exits into an inside of the air box.

摘要： 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.

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.
