A Kylpor ejector is a type of steam locomotive exhaust system developed by noted Argentine locomotive engineer Livio Dante Porta.
The Kylchap was not the only advanced steam locomotive exhaust: another design, the Lemaître, had some success in France and England; noted Argentinian engineer Livio Dante Porta designed several, the Kylpor, Lempor and Lemprex designs; and several U.S. railroads including the Norfolk & Western used a concentric nozzle known as the waffle iron exhaust.
