Abstract: Methods and systems are provided for improving the efficiency of canister purge completion. Based on engine operating conditions, a canister is purged to a compressor inlet or a throttle outlet. During purging conditions, as canister loads change, a purge flow through the canister is varied so that a fixed preselected portion of total engine fueling is delivered as fuel vapors.

Abstract: A vehicle system includes a memory device, a communication interface, and a processing device. The memory device stores a primary keyless entry code associated with a vehicle. The communication interface receives an update command to change the primary keyless entry code to an updated keyless entry code. The processing device stores the updated keyless entry code in the memory device. When an authorized person provides the updated keyless entry code to the vehicle via, e.g., a keypad, the authorized person may gain access to the vehicle.

Abstract: Methods and systems are provided for estimating a fuel concentration in engine oil in an engine crankcase. In one example, an engine controller may adjust engine operation such as EGR flow and engine fueling based on the estimated fuel concentration in engine oil. The fuel concentration may be based on an output of an intake oxygen sensor when purge and EGR flow are disabled, engine oil temperature, and fuel composition.

Abstract: A chabazite (CHA) zeolite catalyst containing iron and copper is provided as an SCR catalyst for reducing nitrogen oxides (NOx) from vehicle engine exhausts. The catalyst is formed by incorporating iron during synthesis of the chabazite zeolite, followed by incorporating copper in an ion-exchange step. The resulting catalyst reduces nitrogen oxides over a wide range of temperatures from about 200° C. to about 700° C.

Abstract: A vehicle traction battery system may include a battery pack, a fan configured to direct air flow to the pack, and a controller. The controller may be programmed to, in response to a predicted pack temperature being greater than a first predefined temperature, direct the fan to operate at a predefined generally constant speed that does not change with vehicle speed or engine on/off state until the predicted battery pack temperature falls below a second predefined temperature. A method is also provided for cooling the vehicle traction battery system based on a predicted battery pack temperature and a heat generation rate.

A release aperture is disposed on one of either the first and second retention tabs and is configured to receive a tool for releasing the first and second retention tabs from the open frame portion of the hook member to release the hook member from the mounting bracket.

Abstract: An adjustable front fascia for vehicles includes a second vehicle structure that is fixed to a first vehicle structure at a location that is predefined relative to a hood of the vehicle. During assembly, the front fascia is movably supported on the second vehicle structure utilizing a temporary retaining mechanism that prevents unintended fore-aft movement of the front fascia unless a force exceeding a predefined release force is applied to the fascia. The front fascia can be fixed at a location providing a predefined gap relative to a front edge of the hood. The vertical position of the fascia relative to the hood can also be adjusted during assembly.
