This invention is related to a non-contact sensor device for electric throttle, comprising a body and a cover. A drive assembly is set in the body and has a shaft corresponded to the on/off state of a throttle valve. An adaptor is installed on the shaft, and a magnet element is set on the adaptor. A Hall element is set on the cover to correspond to the magnet element for detecting the rotation angle of the shaft, thereby knowing the air inflow value and the open angle of the throttle valve to control the fuel injection of fuel-air mixture.

An exhaust gas flap drive for an internal combustion engine, including a driveshaft which has a central axis m, an exhaust gas flap shaft, which is indirectly connected to the driveshaft and has a central axis k, and a coupling element, which is designed as a spring. The coupling element has a first end portion which is rotationally fixed to the driveshaft, and the driveshaft has a receiving area in which the end portion is mounted. The coupling element additionally has a second end portion which is rotationally fixed to the exhaust gas flap shaft via a coupling element, and the receiving area is designed as a groove which is provided on the end face of the driveshaft. The groove has a groove base and two groove flanks which delimit a width b of the groove. The width b decreases towards the groove base, and/or the coupling element has a form-fitting connection with the second end portion in a direction of the central axis k.

Methods and systems for operating an engine that is coupled to a transmission that includes a power take off output are presented. In one non-limiting example, the engine may be operated in a speed control mode and a user may request smoother engine operation or more efficient engine operation via a human/machine interface. The more efficient engine operation may include operating the engine with fewer activated cylinders as compared to operating the engine for smoother engine operation.

Fuel injection control of an engine is executed by setting a required injection amount and an air-fuel ratio correction amount. When setting conditions are met, the air-fuel ratio correction amount is set for a corresponding region to which a current intake air amount or load ratio belongs among a plurality of regions into which the range of the intake air amount or the load ratio is divided such that a region of a larger intake air amount or a higher load ratio becomes wider than a region of a smaller intake air amount or a lower load ratio. When purge conditions are met, a purge control valve is controlled such that purge of supplying an evaporated fuel gas to an intake pipe is executed based on a required purge ratio.
