More than a pretty face
The cowling surrounding a reciprocating engine is a sophisticated aerial garbage disposal. Its job is to throw away about $1.50 out of every $6 you spend on avgas. Gasoline contains more energy per pound than TNT, but engines turn only about a quarter of that energy into useful power. What happens to the rest? It dribbles off as waste heat, to be absorbed by the atmosphere. Half blows out the exhaust pipe; some of that, however, can be harvested and put to good use by a turbocharger.
