❓ Frequently Asked Questions
What is a steam engine?
A heat engine that uses steam to convert thermal energy into mechanical work by moving a piston inside a cylinder.
How does a steam engine work?
Water is heated to produce steam which enters a cylinder, pushes the piston, and the motion is converted to rotary motion by a connecting rod and crank; valves control steam intake and exhaust.
What are the main parts of a steam engine?
Boiler to create steam, cylinder and piston, connecting rod and crankshaft to convert motion, valve gear to admit/exhaust steam, and often a condenser or exhaust system.
What improvements did James Watt bring to steam engines?
He introduced a separate condenser and other refinements that greatly increased efficiency, enabling more practical and widespread use of steam engines.
