Internal Combustion Engine vs External Combustion Engine

On a larger scale, the example of a Lego made motors efficiency can relate to that of a modern day car and the efficiency / energy waste that comes from it. The internal combustion engine is an engine in which the combustion of a fossil fuel mixes with air in a chamber of the operational fluid flow circuit.

The invention of the internal combustion engine sprouted from the work of several engineers and inventors across Europe and into America. First, in 1859, Jean-Joseph Etienne Lenoir developed the first practical internal combustion engine which after many modifications and changes, led to the modern engine that plays a crucial role in today’s society. Prior to Lenoir, external combustion engines such as the steam engine and early hydrogen engine

The continuing rotation of the crankshaft drives the piston back up, ready for the next cycle. The piston moves in a reciprocating motion, which is converted into circular motion of the crankshaft, which ultimately propels the car. Gas engines usually have about the same about of horsepower as they do torque. The diesel engine usually has twice as much torque as it does horsepower, thus it is the better hill climber and load carrier.

The final and most important steps of the Internal Combustion Engine are the movements of the pistons. At this point in the process fuel, and air are both present inside the chamber and are combined into a ratio, this is called the air fuel ratio, short AFR. There are four motions of each piston; they are in perfect balance and harmony, much like watching an orchestra perform. These motions (strokes) are detailed as follows:

One significant innovation was the engine that was created in 1712 by Thomas Newcomen. It was, first created to be used in navigation and succeeding to power machinery which revolutionized the world and started the industrial era. The engine acts as a powerhouse making machines move, but needs fuel to keep it running. Mechanical Engineers are assigned to learn the functions of the engine itself and understand how to further improve it by making it reduce the consumption of fuel or to increase the power output. Unlike automobiles, ships and airplanes with their size, still need lots of fuel due to tremendous power needed to be able to move. Cars that run using electricity do not handle gas for fuel, making it eco-friendly, however they do not provide as much power as the cars that run with gas.

First of all, what are the steam engine and internal combustion engine? The steam engine was first created in 1698, then was reintroduced in 1763 by James Watt. A steam engine works by boiling a big tank of water, called the boiler, under high pressure to produce steam. Tubes run from the firebox to the chimney and carry the

Steam engines were the first engine type to see use in industrial purposes. A fire heats water which turns to steam and the steam then has the ability to move things. They were first invented by Thomas Newcomen in 1705, and James Watt (a Scottish inventor) made big improvements to steam engines in 1769. Steam engines powered all early cars, steamboats and factories.

He created this steam-powered toy for the Chinese Emperor Chien Lung. There is no recorded information about the vehicle itself, only the event. This marked the beginning of the steam-propelled era. The first full size automobile able to move by its own power was built in 1769 by Nicholas Joseph Cugnot. This vehicle was powered by a steam engine and mainly used as a military tractor. Because of its weight, it could only accelerate to 2.5 miles per hour. Then during 1885 and 1886, the first gasoline vehicle was designed and built by Karl Benz in Germany; this was the first true automobile (Bellis- “The History of the Automobile”). Others before tried to build a full-sized vehicle that could move under its own power, but none succeeded until Benz. Although Benz built what is considered the first true automobile, it had mechanical errors and there were no suitable roads to drive on. Another seven years passed before the first successful gas-powered car was built in America by Frank and Charles Edgar Duryea in 1893. They later set up the first car manufacturing plant in America to produce identical automobiles (Bruno).

When Nicolaus Otto built his famous four-stroke engine in 1876, he chose it to use gasoline (Gilles 2). It was probably because gasoline was the most abundant fuel, and because it had a relatively high energy density

Steam engines were invented on February 21, 1804 by Richard Trevithick. The locomotives use steam as a power source. These locomotives use combustible material such as coal, wood, and oil as fuel. Water and fuel supplies are usually on the locomotive or in a trailer behind it. Steam engines were first invented in great britain in the 19th century. It was mostly used for railroad transport until about halfway through the 20th century. In this paper I will explain the history of steam locomotives and how they changed people's lives and America as a whole.

These experimental cars ran on steam, gasoline, or electricity. By the 1890 europeans were buying and driving cars made by Duryea, Haynes Winton, and others. A steam car burned fuel that heated water in a boiler.

engine uses fuel combustion to pump its cylinders to produce power. The more air that is in the

The invention and use of the internal combustion engine was a pivotal point in the history of the automobile. The first attempt at an internal combustion engine was in 1673 by Christian Huygens, using gunpowder as the fuel source, though it was basically worthless as you had to open the engine up and put new gunpowder in it after every single stroke ("The Fuel & Engine"). This lack of a fuel for internal combustion engines sidelined its development for a couple hundred years. In 1860 Jean Joseph Etienne Lenoir built the first effective internal combustion engine using natural gas (Bottorff). The ignition of the gas would create a vacuum and the resulting pressure difference between the vacuum and the atmosphere would drive the power stroke (Bottorff). This gas-atmospheric engine, as it is known, was an effective system capable generating 20hp, still it was imperfect. It was further improved with the development

A very common variant of the internal combustion engine is the four stroke engine. These engines have four "strokes" for each combustion cycle. These engines are

The first engine invented was the internal combustion engine in France in 1860. The engine was unreliable though, so this lead to improvements. These improvements led to the invention of the V-engines. As the years pasted new versions of the V-engines were made with more cylinders. If the original internal combustion engines were used in the original cars, it could have led to horrible disasters. The Invention of the V-engines improved car efficiency with its mpg and will always improve due to newer versions being made such as the V12 engine. These improvements helped cars become efficient and engines will always continue to
