Abstract: Methods and systems are provided for a vehicle having a plurality of axles and a lift mechanism configured to dynamically transfer weight from one axle to another. In one example, the method comprises, responding to an operating condition by adjusting the lift mechanism to provide a determined amount of lift, and in response to vehicle braking, a vehicle stall risk, poor infrastructure conditions, and/or a high vehicle penalty, reducing the determined amount of lift.

Abstract: A method of operating an engine system is described in which a back-pressure valve of a low pressure EGR system can be modulated at a lower frequency during an EGR operation, and at a higher frequency when additional exhaust gas sensing is requested. Back-pressure valve modulation can therefore be used to promote exhaust gas mixing while providing EGR. Exhaust gas constituents in the mixed exhaust gas can then be sensed with higher accuracy by downstream exhaust gas sensors.

Abstract: Systems and methods for personalized media recommendation are provided. One example system may include a media server including a media database containing a plurality of media tracks and a database schema defining multiple media styles. The media server may further include a media delivery engine configured to transmit media tracks to each of a plurality of media clients. The system may further include a feedback module configured to receive history data from each of the media clients. Further still, the system may include a recommendation engine configured to compute a plurality of user-specific style weights, and to select one or more recommended media tracks for each user, The recommendation engine may be further configured to send a recommendation message to the media client including media links to the recommended media tracks on the media server, to cause the media client to display the media links to a user.

Abstract: A method for operation of an engine fuel system includes initiating a mitigating action based on a fuel rail pressure response, the fuel rail pressure response occurring after an engine shut-down. The mitigating action includes disabling vehicle operation if fuel rail pressure drops below a threshold value after activation of one of the higher or lower pressure pumps, the activation occurring before a subsequent engine start. In this way, a distinction can be made between internal and external leaks, allowing the mitigating action taken to be adjusted accordingly.

The multigame party module may be configured to establish a peer-to-peer connection between the computing device and a peer computing device of a remote peer in response to a request from a remote peer to join the party session, and place one or more selected party session members into a first game session of a first multiplayer game software application.

Abstract: An air induction system hydrocarbon trap is provided. In one example, the hydrocarbon trap includes an adsorber roll including an adsorbing material and a corrugate support, where the corrugate support is rolled with the adsorbing material to form a wound adsorber roll. A housing is further provided to retain the adsorber roll. A housing cap may be coupled to the housing.

Abstract: Methods are provided for operating an engine with a variable fuel blend in a cylinder, where the variable fuel blend varies a peak achievable engine torque for a given operating condition. One example method comprises selectively operating an engine actuator that affects engine torque and engine fuel economy at the given operating condition, and extending operation of the actuator to higher engine torques as a peak engine torque for the given operating condition increases.

In one example, the method provides for charging and purging two fuel vapor canisters independently or at the same time. The method may provide for improved fuel vapor processing under some conditions.

The system may include a first flange on a duct connection side, a second flange on an injector connection side, a stand-off separating the first flange from the second flange to form an air gap therebetween, and a seal offset from at least one of the first and the second flanges and located within the airgap and between the first flange and the second flange.

Abstract: Systems and methods for reducing NOx emissions using a branched exhaust system with a first and second turbine including an emission-control device containing a zeolite, are described. In one example approach, a method comprises: during a first duration when exhaust temperature is below a first temperature threshold, directing exhaust gas through the second turbine and the emission-control device, and adjusting the second turbine to control intake boost; and during a second duration following the first, directing exhaust gas through the first turbine, and adjusting the first turbine to control intake boost. In this way, the first and second turbines may provide a greater degree of boost control in order to reduce boost fluctuations while enabling storing cold start NOx emissions for later reduction.

In one example, during an engine shutdown, torsion is maintained in a transmission gear-train until an engine restart is requested by engaging one or more transmission clutches while applying wheel brakes.

One example method comprises, in response to a first vehicle moving condition, shutting down the engine and at least partially disengaging the transmission while the vehicle is moving; and during a subsequent restart, while the vehicle is moving, starting the engine using starter motor assistance and adjusting a degree of engagement of a transmission clutch to adjust a torque transmitted to a wheel of the vehicle.

Abstract: During operation of a spark ignition engine, an ignition system produces an output (e.g., breakdown voltage, peak secondary coil current, and spark duration) used to combust a charge (e.g., mixture of air and fuel) in an engine cylinder. Ignition output is important to consider in engines including a second fuel with high ignitability, for example in engines with a fuel reformer system. Example methods, devices and systems are included for adjusting ignition output.
