Morphology

outstroke = stroke (semi-transparent) = out + stroke

The prefix 'out-' suggests a direction or movement outward, but the specific technical meaning related to engine pistons may not be immediately clear to all learners.

Etymology

The word outstroke is made from the parts out ('away') and stroke ('a single movement', as in a swimming stroke or the stroke of a pen). So, an outstroke is the piston moving 'out' toward the crankshaft during the engine cycle.
