The first practical steam engine was patented by James Watt in 1769. Steam engines worked like this. The water in a holding tank would be heated up and pressure would build in the tank. Once the water pressure was built up high enough the pressure was released to make power and propel the vehicle. Some examples of steam powered vehicles are Trains, ships, and cars. There were ups and downs for this type of engine though. On the up side of steam power it’s has the ability to convert raw heat into mechanical work. Also steam engines burn fuel cleanly and efficiently, with relatively little pollution. One down fall to the steam engine is, the engine would loss pressure and you would have to stop and let the pressure rebuild itself before you could move on. Without steam engines being invented, nuclear engines probably would not have been invented. The gasoline engine is a engine that is ran off of gas. The gas gets sprayed into a cylinder and mixed with air. When that happens a spark is ignited and makes a explosion in the cylinder. This makes the piston move up and down at a very high speed. The piston is connected to a crank shaft and that is connected to a transmission. The transmission will turn a drive shaft and that will make your car move. This was a improvement over the steam engine. There was not any more stop and wait for the pressure to build. This kept you moving for longer periods of time. This also gave you a lot more power and speed. The downfall to this is the pollution that is given off from these engines. There are also other types of internal combustion engines like the two stroke engine. This is normally used for smaller engines like chainsaws, jet skis, and small motorcycles. In 1897 Rudolf Diesel made his firs successful diesel powered engine. He proved that fuel can be ignited without spark. Diesel engines are often…...

...Steam Turbines The invention of the water turbine was so successful that eventually, the idea came about for extracting power from steam. Steam has one great advantage over water-it expands in volume with tremendous velocity. To be the most effective, a steam turbine must run at a very high speed. No wheel made can revolve at any speed approaching the velocity that a steam turbine can. By utilizing the kinetic energy of steam flow, the turbine could achieve a higher efficiency. As a result, the steam turbine has supplanted the reciprocating engine as a prime mover in large electricity-generating plants and is also used as a means of jet propulsion. The action of the steam turbine is based on the thermodynamic principle that when a vapor is allowed to expand, its temperature drops. In turn, its internal energy is decreased. This reduction in internal energy is transformed into mechanical energy in the form of an acceleration of the particles of vapor. The transformation that occurs, provides a large amount of available work energy. The essential parts of all steam turbines consist of nozzles or jets through which the steam can flow and expand. Thus, the temperature drops, and kinetic energy is gained. In addition, there are blades, on which high pressure steam is exerted. Stationary blades shift the steam onto rotating blades, which provide power. Also, turbines are equipped with wheels or drums where the blades are mounted. A shaft for......

Being a soldier, killing the bad guys, or being the new star of European soccer fields scoring in the final of the UEFA Champions League, every men “normally” constituted has dreamed at least once to be in that situation, and video games can procure that kind of excitement. This is the reason why I choose to make my final e-business assignment on video games. Concerning my choice for the company, for me it was obvious to choose Steam. In my point of view, they have been the precursor of many things in e-business, or at least they were one of the first that used “e-novations”. Through the years, they have succeeded in being one of the most important company in this sector. Many factors have to be pointed out. First, the fact that they have created one of the best games ever made which is Half-Life. It allows them to have a world-wide recognition. Secondly, the Valve platforms, with its large numbre of games available, the exchange of data and information between players and users, have made them the first online retailer for video games.

James Watt: Perfecter of the Steam Engine

...the Steam Engine The world we live in today is is fast paced, competitive, and ever evolving. Being accustomed to such a rapidly changing and highly inventive society can make it very difficult to imagine the way people lived centuries ago. Before the Industrial Revolution, most everything was done by hand, required a great deal of time and effort, and was terribly expensive. During the eighteenth and nineteenth centuries, intuitive thinkers would invent and perfect machines, tools, and devices, forever changing the ways of the world. In the following paragraphs, James Watt and his steam engine will be discussed in detail, along with their enormous influence in modernizing the world's industries, trade, transportation, and economy. James Watt was born in Scotland in 1736, and died in 1819. His life spanned many of the years in the most dynamic period in the history of the world. Watt also lived in the United Kingdom, which, at the time, was the most rapidly evolving country on earth. Contrary to popular belief, James Watt did not invent the steam engine. In The Scientific Monthly, authors accurately portray Watt as, "a scientist rather than inventor" (Ambrosius and Reed 272). People had been using steam for power several centuries before Watt's time, but "English military engineer and inventor, Thomas Savery, [was] the first to create a specific device to harness and channel the power of steam" (Ambrosius and Reed 272). It was Savery who patented the first......

The Engine

...The Engine The engine is a machine that converts chemical energy of fuel into mechanical energy. The heat from combustion of a fuel produces power which propels the car. Sometimes the engine is even called the power plant of a car.  There are two types of engine 1. Internal combustion engine( combustion of fuel takes place internally) 2.External combustion engine( combustion of fuel takes place externally) In the external combustion engines the power is generated outside the engine cylinder    by burning the fuel and it is transferred to the cylinder by means of some working fluid (steam) to do work.The example for an external combustion engine is a steam engine which was used in the locomotives,this is a double acting engine which means the pressure acts on both sides of the piston alternatively making it to reciprocate  inside the cylinder. In an Internal combustion engine the power is developed inside the engine cylinder by burning the fuel in the cylinder itself.The heat energy produced during the combustion of fuel is converted into mechanical energy by the expansion of gases against the piston due to which it rotates the crankshaft attached to it by means of a connecting rod (connecting rod is used to connect the piston with the crankshaft to convert the reciprocating motion of piston into rotary motion of the crankshaft). Types of internal combustion engine Engines can be classified in many different ways: By the engine cycle used, the layout......

Locomotive Engine Design

...Name Course Tutor Date Steam engine design Steam engines powered a good number trains as of the early 1800s to the 1950s. Although the engines differed in size and complexity, their basic operation remained basic as illustrated in this paper. The engine is a double-acting steam engine since the valve lets high-pressure steam to function alternately on the two surfaces of the piston. The control rod for the valve is typically hooked into a connection attached to the cross-head; therefore, the movement of the cross-head slips the valve as well. On a steam engine, this connection in addition lets the engineer to set the train into reverse. The exhaust steam just escapes out into the air. On a steam locomotive, the cross-head typically connects to a drive rod, and from there to pairing rods that force the steam engine's wheels (Brain howstuffworks.com). In a steam train, the boiler which is fueled by wood, oil, or coal, constantly boils water in an enclosed compartment, creating high-pressure vapor. The cross-head is linked to a drive rod that attaches to one of drive wheels of the locomotive. The three wheels are linked using coupling rods thus they turn in harmony First stroke and exhaust Steam commencing from the boiler goes into the steam chestand is admitted to the front ending of the cylinder by way of a valve slide. The high pressure steam presses the piston to the back, forcing the locomotive wheels around single half turn.At the end of the piston stroke, the......

Driven by a Steam Engine

...Driven by a Steam Engine The Second Industrial Revolution was characterized by the enormous advances in production technology ushered in by the advent of steel and harnessing of electricity. The beneficiary of these advancements were railway manufacturers, who utilized these innovations to move past the cumbersome steam engine railways to electric railways powered by diesel engines and built on cheaper, stronger steel tracks. Railroads became faster, cheaper, and more comfortable, and the rapidly growing industry provided many North Americans with dreams of building the first transcontinental railway that would propel them into generations of prosperity. Two such North Americans were William Mackenzie and James J. Hill, Canadians who made it their lifelong goal to build the first transcontinental railway. Ultimately, Hill succeeded in achieving his dream while Mackenzie’s railway floundered through bankruptcy and shoddy assembly. The difference between Hill’s success and Mackenzie’s failure lay in their approaches to building railway empires. Where Hill was the single-minded perfectionist, relying only on himself in every aspect of his Great Northern Railway, Mackenzie treated his Canadian Northern Railway as one of his many hobbies, giving his attention only to facets of the railway that interested him and frequently relying on others for aid. Mackenzie and Hill’s different attitudes set them apart in their devotion to their dream, attention to detail, and varying levels......

Diesel Engine

...The diesel engine (also known as a compression-ignition or CI engine) is an internal combustion engine in which ignition of the fuel that has been injected into the combustion chamber is initiated by the high temperature which a gas achieves when greatly compressed (adiabatic compression). This contrasts with spark-ignition engines such as a petrol engine (gasoline engine) or gas engine (using a gaseous fuel as opposed to petrol), which use a spark plug to ignite an air-fuel mixture. A Diesel engine built by MAN AG in 1906 The diesel engine has the highest thermal efficiency (engine efficiency) of any practical internal or external combustion engine due to its very high expansion ratio and inherent lean burn which enables heat dissipation by the excess air. A small efficiency loss is also avoided compared to two-stroke non-direct-injection gasoline engines since unburnt fuel is not present at valve overlap and therefore no fuel goes directly from the intake/injection to the exhaust. Low-speed diesel engines (as used in ships and other applications where overall engine weight is relatively unimportant) can have a thermal efficiency that exceeds 50%.[1][2] Diesel engines are manufactured in two-stroke and four-stroke versions. They were originally used as a more efficient replacement for stationary steam engines. Since the 1910s they have been used in submarines and ships. Use in locomotives, trucks, heavy equipment and electricity generation plants followed later. In the......

Steam Engine

...Steam engines are external combustion engines,[1] where the working fluid is separate from the combustion products. Non-combustion heat sources such as solar power, nuclear power or geothermal energy may be used. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In the cycle, water is heated and transforms into steam within a boiler operating at a high pressure. When expanded through pistons or turbines, mechanical work is done. The reduced-pressure steam is then condensed and pumped back into the boiler. In general usage, the term steam engine can refer to either the integrated steam plants (including boilers etc.) such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Specialized devices such as steam hammers and steam pile drivers are dependent on the steam pressure supplied from a separate boiler. Using boiling water to produce mechanical motion goes back over 2000 years, but early devices were not practical. The Spanish inventor Jerónimo de Ayanz y Beaumont obtained the first patent for a steam engine in 1606.[2] In 1698 Thomas Savery patented a steam pump that used steam in direct contact with the water being pumped. Savery's steam pump used condensing steam to create a vacuum and draw water into a chamber, and then applied pressurized steam to further pump the water. Thomas Newcomen's atmospheric engine was the first......

Turbine Engines

...Turbine Engines The history of turbine engines date back to nearly a century ago when Frank Whittle was the first to register a patent in 1930; six years later Hans von Ohain registered his independent work (Bellis, 2012). Frank Whittle, as an English aviation engineer and pilot, gained private financial support to start designing and manufacturing his first turbojet in January 1930 (Bellis, 2012). His first engine was a single-stage centrifugal compressor attached to a single-stage turbine was tested in 1937 (Bellis, 2012). The jet engine has become very complex engine based on simple concepts; in simplest terms, the jet engine produces thrust for flight by compressing, combustion, and accelerating air out the exhaust faster than when it came in the inlet. Throughout my career, I have maintained, troubleshot, and repaired several different types of turbine engines, all of which are similar because of this theory of operation. When looking at a jet engine, everyone usually sees the fan blades, but before this component, there is the inlet, or intake, which is the structure in front of the fan. For aircraft that cannot fly supersonically, the inlet is a basic housing that directs air straight into the fan; for much faster aircraft, the inlet is longer and contains a slight curve as it leads to the fan. This is because when the aircraft is flying at supersonic speeds, the air entering the jet engine must be slowed to subsonic speeds (“the jet engine,” n.d.). It is...

...Tutorial - Full Throttle Engine Most gas R/C models use a 2- or 4-stroke glow engine, sized specifically for that model. Most glow engines have a simple ignition system that uses a glow plug rather than a spark plug so there's no coil, magneto or points. The glow plug is heated by a batteryoperated glow starter. When fuel enters the combustion chamber, it's ignited by the heated glow plug and with that, the engine springs to life, instantly gaining the momentum to continue running after all the starter accessories are removed. The engine's carburetor supplies the fuel and air needed for combustion. It has several adjustments. A rotating throttle arm controls the AMOUNT of fuel and air that enters the combustion chamber. The high- speed needle valve controls the MIX or proportions of fuel vs. air at mid- to high-speeds. The idle mixture screw is similar to the high-speed needle valve, except that it controls the mix of fuel and air when the engine is only idling. When you've adjusted the highspeed and idle mixtures properly, your engine should operate smooth and steady throughout its speed range. Glow plugs A gasoline combustion engine uses a spark plug to ignite the fuel- air mixture within the compression chamber, so a glow or nitro engine uses a small glow plug. Although the plug needs to be heated up using a glow plug igniter initially, once the engine is running, the heat generated within the combustion chamber keeps the plug glowing constantly and......

Engine

...Engine Architecture In the preceding chapter several concepts basic to diesel and spark ignition engine were covered. Building on this background, this chapter introduces the steps involved in designing a new engine to meet the needs of particular customers and markets. The chapter begins with a summary of criteria and customer expectations which must be met in the design of an engine. The criteria include both limitations placed on the design by available technology and production costs, and the regulations which must be met in the chosen markets. The engine operating map is then summarized in terms of torque and horsepower versus engine speed. Determining the required engine displacement, and the relationship between displacement and boost is then covered, and the chapter concludes with a discussion of engine configuration, focusing on determining the optimum bore to stroke ratio. 2.1 Product and Technical Profiles The first step in designing a new engine is to develop a clear understanding of the markets to which the engine will be supplied, and the needs and expectations of customers in each market. The relative importance of various engine attributes will vary from one market to another, and unfortunately this often results in compromises when attempting to develop an engine for more than a single market. Attributes important to the customer fall into the two categories of product performance and operational cost. Product performance includes such......
