  • Method and system for purge control
    Patent number: 10968846
    Abstract: Methods and systems are provided for reducing engine stall incidence during canister purging. A fuel vapor canister is purged at a higher purge ramp rate to an engine with one or more cylinders selectively deactivated. In response to an indication of potential or partial engine stall, the deactivated cylinders are reactivated and the canister purge ramp rate is lowered.

  • Systems and methods for improving vehicle engine stability
    Patent number: 10961937
    Abstract: Methods and systems are provided for conducting a diagnostic on a fuel tank isolation valve that regulates a flow of fuel vapors from a fuel tank to an evaporative emissions system. In one example, a method comprises determining whether the fuel tank isolation valve is stuck in a first open position or a second open position based on a time duration between commanding open a canister purge valve to direct fuel vapors to an engine, and an exhaust gas sensor indicating a rich air-fuel ratio. In this way, appropriate mitigating action may be taken in response to the fuel tank isolation valve being stuck in either the first open position or the second open position.

  • Systems and methods for reducing vehicle evaporative emissions
    Patent number: 10940854
    Abstract: Methods and systems are provided for reducing bleed emissions and exhaust emissions from a vehicle that may be operated autonomously as well as part of a car-sharing model. A parking location of the vehicle is selected at the end of a vehicle event requested by an operator as a function of fuel system and evaporative emissions system variables such that the solar loading of the parking location enables reduced emissions. The parking location selection is further coordinated with the pick-up time and location of a subsequent vehicle event requested by another vehicle operator.

  • Method and system for evaporative emissions system purging during engine restart
    Patent number: 10914249
    Abstract: Methods and systems are provided for purging a fuel vapor storage canister in an evaporative emissions system of a vehicle. In one example, a method may include generating vacuum in a fuel tank fluidically coupled to the fuel vapor storage canister during an auto-stop of an engine while the engine spins down to rest, and purging vapors to an intake manifold of the engine during a subsequent restart of the engine. In this way, the fuel tank may be held at a vacuum while the engine is off, enabling more efficient purging of the fuel vapor storage canister when the engine is restarted.

  • Cooling fans for engine cooling system
    Patent number: 10900499
    Abstract: Systems and methods are provided for a bladeless radiator cooling fan. In one example, a system may include a plurality of bladeless entrainment discs surrounded by a shroud, each bladeless entrainment disc including a hollow central opening that enables unrestricted ambient airflow through the cooling fan, and a source fan for providing airflow to the bladeless entrainment that is encased by a housing. In this way, airflow through the bladeless radiator cooling fan may be increased, decreasing powered fan usage and decreasing fan noise.

  • Methods and system for conducting an engine system diagnostic based on ambient noise
    Patent number: 10900444
    Abstract: Methods and systems are provided for conducting an engine diagnostic for a vehicle based on an amount of noise proximate to the vehicle. In one example, a method (or system) for a vehicle may include determining an ambient noise level surrounding the vehicle based on data received from autonomous vehicle sensors and conducting an engine diagnostic by operating a pump, motor, and/or actuators responsive to the determined ambient noise level. The engine diagnostic may be conducted while the vehicle is keyed off or while the engine is running and may be further conducted based on a proximity of human activity to the vehicle.

  • SYSTEMS AND METHODS FOR PREVENTING ENGINE STALL
    Publication number: 20200347804
    Abstract: Methods and systems are provided for reducing or avoiding engine hesitation and/or stall during engine idle conditions. In one example, a method may include inferring an engine idle condition, and in response, controlling a speed of an engine to a compensated engine idle speed that is a function of an extent to which a canister purge valve that regulates an amount of fluid flow to the engine from a fuel system and/or an evaporative emissions system, is degraded. In this way, an amount of fuel utilized to compensate for the degraded canister purge valve may be proportionate to the extent to which the canister purge valve is degraded.

  • Systems and methods for controlling fuel vapor canister purging operations
    Patent number: 10794312
    Abstract: Methods and systems are provided for increasing an efficiency of a purging operation of a fuel vapor storage canister of a vehicle, the fuel vapor storage canister configured to capture and store fuel vapors stemming from a fuel tank of the vehicle. As one example, a method comprises reactivating one or more cylinders of an engine during a purging operation, in response to an indication that the purging of stored fuel vapors from the fuel vapor storage canister is compromised as a result of fuel vaporization stemming from the fuel tank. In this way, the canister may be effectively cleaned even under high fuel vaporization circumstances, which may improve fuel economy and may reduce release of undesired evaporative emissions to atmosphere.

  • SYSTEMS AND METHODS FOR REDUCING ENGINE OVERHEATING USING LIQUID FUEL
    Publication number: 20200300155
    Abstract: Systems and methods are provided for cooling an overheated engine using a combination of variable displacement engine (VDE) technology and direct injection technology. In one example, a method may include deactivating a subset of engine cylinders based on an engine temperature and directly injecting liquid fuel into the deactivated cylinders. In this way, an increased thermal conductivity of the liquid fuel compared to air decreases the engine temperature at a faster rate than when air-based engine cooling methods are used, thereby preventing overheating-related engine degradation.

  • SYSTEMS AND METHODS FOR DIAGNOSING EJECTOR SYSTEM DEGRADATION FOR DUAL-PATH PURGE ENGINE SYSTEMS
    Publication number: 20200291879
    Abstract: Methods and systems are provided for conducting an ejector system diagnostic under conditions where an engine of a vehicle is not combusting air and fuel. In one example, a method comprises directing a positive pressure to the ejector system while the engine is off in order to communicate a negative pressure with respect to atmospheric pressure on a fuel system and an evaporative emissions system of the vehicle, and indicating that the ejector system is degraded responsive to the negative pressure not reaching a vacuum build threshold. In this way, the ejector system may be diagnosed under conditions where boosted engine operation is infrequent and/or of durations insufficient for conducting such an ejector system diagnostic.

  • Systems and methods for onboard canister purge valve flow mapping
    Patent number: 10767599
    Abstract: Methods and systems are provided for controlling a duty cycle of a purge valve configured to regulate a purge flow from a fuel vapor storage canister to an intake of an engine during canister purging events. In one example, a method includes controlling a duty cycle of a purge valve configured to regulate a purge flow from a fuel vapor storage canister to an intake of an engine during a canister purging event based on a degradation factor obtained by comparison of durations at which a predetermined pressure is reached in an evaporative emissions system at multiple purge valve activation levels. In this way, a flow map stored at a controller may be updated for controlling the purge valve during subsequent purging events.
