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.

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 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： A vapor canister of an evaporative emissions (EVAP) system is configured to store fuel vapor evaporated from a liquid fuel housed in a fuel tank of a vehicle. A boost line is connected between a high-pressure side of a boost system of an engine and the vapor canister, a boost pressure control valve is disposed in-line along the boost line and configured to control an amount of boost pressure provided to the vapor canister, and a set of purge lines are connected between the vapor canister and at least one of the engine, an induction system of the engine, and an exhaust treatment system of the engine. A controller is configured to control the boost pressure control valve to control the boost pressure provided to the vapor canister to control an amount of fuel vapor forced from the vapor canister through at least one of the set of purge lines.

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： 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： 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 loose or missing fuel cap detection method for an evaporative emission control system of an automotive vehicle detects a loose or missing fuel cap based in part on whether fuel level changed. The method determines whether the fuel level changed, which is indicative of a refueling event. The method then determines if one or more leaks are present. If the fuel level changed and one or more leaks are present, the method determines that the fuel cap is loose or missing.

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.
