Systems and methods determining a presence or absence of engine misfire at low engine load are disclosed. In one example, the presence or absence of engine misfire is based on a fuel target error value and an exhaust temperature error. Operation of an engine may be adjusted when engine misfire is detected.

System and method for detecting engine misfire

Methods and systems are provided for fueling an engine of a vehicle during an exit from a deceleration fuel shut-off (DFSO) condition. In one example, a method may include fueling the engine using a compression stroke direct injection during the exit from the DFSO condition to reach a first engine torque threshold, and may further include increasing a separation between the compression stroke direct injection and a spark to gradually increase the engine torque to a second, higher engine torque threshold, and thereafter transitioning engine fueling from the compression stroke direct injection to an intake stroke direct injection. In this way, torque bumps may be reduced during DFSO exit.

Engine fueling during exit from a deceleration fuel shut-off condition

Embodiments for reactivating a catalyst are provided. In one example, a method for reactivating a catalyst coupled to an engine comprises when the engine is restarted following deactivation, adjusting a degree of fuel enrichment based on an engine off duration and an engine air amount during the restart.

Methods and system for catalyst reactivation

The umbrella of the preferred embodiments includes a shaft, a canopy, and a spoke system, coupled to the shaft and to the canopy, which supports the canopy and provides a mechanism to open and close the canopy. The spoke system of the preferred embodiments includes a canopy spoke, coupled to the shaft and to the canopy, having a geometry that defines a canopy coupling element; a support spoke, coupled to the shaft and to the canopy spoke, having a geometry that defines a support coupling element; and a first release mechanism that includes the canopy coupling element and the support coupling element. The umbrellais preferably designed to prevent the passage of precipitation or sun and, more specifically, designed to be an umbrella that can be easily assembled, disassembled, repaired, and recycled. The umbrella, however, may be alternatively used in any suitable environment and for any suitable reason.
