Systems and methods for adjusting an engine air flow transfer function and engine actuators based on the engine air flow transfer function are presented. The system and method may be applied to hybrid powertrains having a capability to estimate engine torque based on operating characteristics of a motor during vehicle operation.

Methods and systems for selectively adapting engine air flow

A method for adjusting an air-fuel ratio of an engine is disclosed. In one example, the engine air-fuel ratio is adjusted in response to a duty cycle and frequency of a post catalyst oxygen sensor. The method may improve catalyst efficiency.

Method for adjusting engine air-fuel ratio

One embodiment of the present invention is a seal apparatus () for an improved front-end to body-side joint () of a vehicle. The seal apparatus () includes a ring portion (), a gate portion (), and an intermediate portion () extending between the ring portion () and the gate portion (). The ring portion () is utilized for receiving an open-ended tubular front-end structure () of the improved front-end to body-side joint (). Additionally, the ring portion () is utilized for sealing an interface between the front-end structure () and a body-side structure (). Further, the gate portion () is sized for insertion into an interior cavity () of the front-end structure () and for blocking communication through the interior. Also, the ring portion () and/or the intermediate portion () have a self-locating construction for positioning the seal apparatus () in a predetermined location () on the front-end structure ().
