Abstract
An engine may include an engine body. A piston assembly may be positioned at least partially within the engine body and including a first piston and a second piston. A connection member may be operably coupling the first piston to the second piston and causing the first piston and the second piston to move in conjunction with one another. A sled may be operably coupled with the connection member. A load member may be operably coupled with sled, the load member movable with the sled. A sensor system may be positioned through at least a portion of the engine body and operably coupled with the sled. The sensor system may include a transmitter configured to direct modulated emitted light into a sled chamber and a receiver configured to receive reflected light from the light source.
