भाप इंजन (Steam Engine) एक ऐसा यंत्र है जो भाप की ऊष्मा ऊर्जा को यांत्रिक ऊर्जा में बदलता है। बॉयलर में बनी भाप पिस्टन को धक्का देती है, जिससे गति और शक्ति उत्पन्न होती है।
A steam engine is a machine that converts heat energy of steam into mechanical energy. Steam produced in a boiler pushes the piston, which creates motion and power to run machines, trains, and engines. Educatormanoj
