Abstract: An engine includes an engine shaft and a piston configured to reciprocate within a cylinder chamber having an axis, each piston having an first piston part and piston stem to move in unison with or separately from a second piston part to define piston strokes for different thermal functions of the engine. The engine further includes a linkage assembly having a first end coupled to the engine and a second end coupled to the piston stem defining a copy point, an actuator that engages the linkage assembly, and a guide cam that engages a guide cam follower on the linkage assembly. The actuator and the guide cam are operable to control motion of the linkage assembly to thereby define substantially linear movement of the copy point along the cylinder chamber axis.

Abstract: The present application relates to a charging station operable in a charging cycle for charging an electric vehicle. The charging station has a key-activated controller for controlling the charging cycle. The application also relates to a key for operating the charging station. Furthermore, the application relates to a charging station having an interface for connecting the charging station to a data network. The application also relates to a charging station having a socket for receiving a plug and a key-operated locking mechanism for locking a plug in said socket. A frangible panel movable between an open position and a closed position may be provided. A processor may be provided for generating data to impose a financial charge on an individual for using the charging station.
