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 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 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 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 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： An evaporative emissions (EVAP) system and its method of control comprise commanding a three-way valve to fluidly connect an auxiliary vapor canister and a bottom portion of a fuel tank, controlling at least one of an engine of the vehicle and a purge pump of the EVAP system disposed between the engine, a separate primary vapor canister, and the auxiliary vapor canister to draws fuel vapor from the fuel tank into the auxiliary vapor canister for storage, commanding the three-way valve to fluidly connect the bottom portion of the fuel tank to an atmosphere outside of the EVAP system to generate additional fuel vapor in the fuel tank, commanding the three-way valve to fluidly connect the auxiliary vapor canister to the atmosphere, and controlling at least one of the engine and the purge pump to draw the fuel vapor from the auxiliary vapor canister into the engine.

摘要： A Venturi-based purge vapor supply system for a turbulent jet ignition (TJI) engine and its method of operation utilize an air compressor configured to output pressurized air, a vapor canister configured to store purge vapor evaporated from liquid fuel housed in a fuel tank, a purge vapor injector configured to inject a mixture of air and purge vapor into a pre-chamber of the TJI engine and an ejector tee connected between the air compressor, the vapor canister, and the purge vapor injector, the ejector tee having a Venturi-based design such that the pressurized air from the air compressor draws the purge vapor into the ejector tee and combines the air and the purge vapor to form and output the mixture of air and purge vapor to the purge vapor injector.
