History of the Steam Engine:
Early Origins
Reconstruction of Heron's aeolipile at the Kotsanas Museum of Ancient Greek Technology in Athens, Greece wikipediaThe history of the steam engine begins with ancient experiments in harnessing steam power. The earliest known device was the aeolipile, described by Hero of Alexandria in the 1st century CE in Roman Egypt. This simple machine used steam to create rotary motion but was considered more a scientific curiosity than a practical engine1245.
17th Century DevelopmentsIn the late 17th century, inventors began to explore steam for practical applications. In 1698, English engineer Thomas Savery patented the first commercial steam-powered device, a water pump known as the "Miner's Friend." Savery's engine used both the pressure of expanding steam and the vacuum created by condensing steam to raise water, primarily for draining mines. However, it was limited by low efficiency and a tendency for boiler explosions1478.
The Newcomen EngineA major breakthrough came in 1712 when Thomas Newcomen developed the first practical steam engine with a piston. Known as the atmospheric engine, it used steam to create a vacuum under a piston, which atmospheric pressure then pushed down. This engine was primarily used to pump water out of mines and marked the first time steam power was harnessed on an industrial scale. By 1800, around 2,000 Newcomen engines were in operation in England13456.
James Watt and Further Improvements

In 1765, Watt introduced a separate condenser to Newcomen's design, greatly improving efficiency by preventing the main cylinder from cooling down with each stroke. Watt also developed engines capable of rotary motion, making them suitable for driving machinery in factories, not just pumps. These innovations were pivotal in powering the Industrial Revolution, enabling factories to be located away from rivers and increasing industrial productivity1457.
Expansion and Applications

Richard Trevithick built the first full-scale working railway steam locomotive in 1804, and George Stephenson's "Rocket" in 1829 made steam-powered railways commercially viable. Steam engines also powered ships, factories, and agricultural machinery, becoming the dominant source of industrial power throughout the 19th century4510.
Decline and LegacySteam engines began to decline in the early 20th century with the advent of more efficient steam turbines and internal combustion engines. Steam turbines remain crucial in electricity generation today, while reciprocating steam engines are largely of historical interest. Nonetheless, the steam engine's development was central to the Industrial Revolution and modern technological society14.

History of the Internal Combustion Engine:
- Gunpowder Piston Engine: In 1673, a Dutchman named Chrstiaan Huygen attempt ed to stuff a piston in a tube like gun barrel and explode gunpowder that caused the piston to move. But it only worked once before the cylinder had to be filled with gunpowder.
- Watt’s and Newcomen’s steam engine: The Scottish mechanical engineer and chemist James Watt who improved on Thomas Newcomen’s 1712 Newcomens steam engine wt. his Watt steam engine, in 1776. which was fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of the world. The basic theory of push and pull of steam engine is to burn to water to high heat and liquid became steam gas and expanded by 1,700 times, high pressure steam pushed the piston forward,, then the cylinder will be cooled down by atmosphere. The steam condensed back to liquid water produced a “cheating vacuum” to pull the piston back to the original position.
- GAS-Atmospheric Engines : In 1859, a Belgian engineer Jean J. Lenoir's experimentation with electricity led him to develop the first internal combustion engine which burned a mixture of coal, gas and air ignited by a "jumping sparks" ignition system by Ruhmkorff coil,[2] and which he patented in 1860. The engine was a steam engine converted to burn gaseous fuel and thus pushed in both directions. The fuel mixture was not compressed before ignition (a system invented in 1801 by Philippe LeBon who developed the use of illuminating gas to light Paris), and the engine was quiet but inefficient,[3] with a power stroke at each end of the cylinder. In 1863, Lenoir demonstrated a second three-wheeled carriage, the Hippomobile, little more than a wagon body set atop a tricycle platform.[3] It was powered by a 2543 cc (155 in3; 180×100 mm, 7.1×3.9in)[2] 1.5 hp, "liquid hydrocarbon" (petroleum) engine with a primitive carburettor which was patented in 1886.[8] It successfully covered the 11 km (7 mi) from Paris to Joinville-le-Pont and back in about ninety minutes each way, an average speed less than that of a walking man (though doubtless there were breakdowns).[2] This succeeded in attracting the attention of Tsar Alexander II, and one was sent to Russia, where it vanished; Lenoir was not pleased. In 1863, he sold his patents to Compagnie parisienne de gaz and turned to motorboats, instead, building a naptha (Ligroin) fueled four-cycle in 1888.[3][2][9] Jules Verne wrote in his 1863 novel Paris in the Twentieth Century of boulevards crowded with horseless carriages, "the Lenoir machine applied to locomotion."
