Morphology
The compound combines 'reciprocate' (move alternately/back-and-forth) with 'engine' (a machine), so its meaning — an engine whose parts move back-and-forth (pistons moving up and down) — is directly derivable from the constituents. This is a regular compositional technical compound found cross-linguistically, so a learner who knows both words would readily infer the MWE meaning.
Etymology
Reciprocating engine gets its name from the clear 'back-and-forth' motion inside: pistons move up and down in cylinders and push a shaft that turns to make power. That's why the term means an engine where parts move 'back and forth' to create motion.
