Abstract: A powered ratchet tool includes a housing with a battery receptacle, a motor within the housing with an output spindle driven about a first axis, a battery configured to be coupled to the battery receptacle to power the motor, a head pivotably coupled to the housing and configured to pivot with respect to the housing about a second axis perpendicular to the first axis and between a plurality of discrete orientations, the head including a ratchet mechanism driven by the output spindle and an output drive coupled to the ratchet mechanism and configured to rotate about an output drive axis, and a locking mechanism moveable between a first position, in which the head is locked in one of the plurality of discrete orientations with respect to the housing, and a second position, in which the head freely pivots between the plurality of discrete orientations about the second axis.

Abstract: A control system for a gaseous-fueled engine is disclosed. The gaseous-fueled engine may have an intake valve mechanically driven by a camshaft. The control system may have a variable valve timing device configured to adjust a cyclical opening and closing timing of the intake valve. The control system may further have a sensor configured to generate a signal indicative of a speed of the engine and a controller in communication with the variable valve timing device and the sensor. In addition, the controller may be configured to selectively initiate a first Miller Cycle timing and a second Miller Cycle timing based on the signal.

Abstract: A fuel air mixer includes a fuel air mixing tube having an inlet, an outlet, and an inlet inner diameter. A collar is attached at the mixing tube inlet and includes a first cylindrical portion upstream of the mixing tube inlet, and a body portion encircling the mixing tube at the mixing tube inlet and forming a fuel reservoir around the mixing tube inlet. The first cylindrical portion is spaced from the mixing tube inlet to create a gap placing the fuel reservoir in fluid communication with the mixing tube inlet. The first cylindrical portion has an inner diameter that is smaller than the inlet inner diameter so air flowing through the first cylindrical portion and into the mixing tube inlet draws gaseous fuel from the fuel reservoir into the mixing tube through the gap.
