The Evolution of Diesel Engines
GENERAL ARTICLE The Evolution of Diesel Engines U Shrinivasa Rudolf Diesel thought of an engine which is inherently more efficient than the steam engines of the end-nineteenth century, for providing motive power in a distributed way. His intense perseverance, spread over a decade, led to the engines of today which bear his name. U Shrinivasa teaches Steam Engines: History vibrations and dynamics of machinery at the Department The origin of diesel engines is intimately related to the history of of Mechanical Engineering, steam engines. The Greeks and the Romans knew that steam IISc. His other interests include the use of straight could somehow be harnessed to do useful work. The device vegetable oils in diesel aeolipile (Figure 1) known to Hero of Alexandria was a primitive engines for sustainable reaction turbine apparently used to open temple doors! However development and working this aspect of obtaining power from steam was soon forgotten and with CAE applications in the industries. millennia later when there was a requirement for lifting water from coal mines, steam was introduced into a large vessel and quenched to create a low pressure for sucking the water to be pumped. Newcomen in 1710 introduced a cylinder piston ar- rangement and a hinged beam (Figure 2) such that water could be pumped from greater depths. The condensing steam in the cylin- der pulled the piston down to create the pumping action. Another half a century later, in 1765, James Watt avoided the cooling of the hot chamber containing steam by adding a separate condensing chamber (Figure 3). This successful steam engine pump found investors to manufacture it but the coal mines already had horses to lift the water to be pumped. -
The Diffusion of Newcomen Engines, 1706-73: a Reassessment*
1 The Diffusion of Newcomen Engines, 1706-73: A Reassessment* By Harry Kitsikopoulos Abstract The present paper attempts to quantify the diffusion of Newcomen engines in the British economy prior to the commercial application of the first Watt engine. It begins by pointing out omissions and discrepancies between the original Kanefsky database and the secondary literature leading to a number of revisions of the former. The diffusion path is subsequently drawn in terms of adopted horsepower and adjusted for the proportion of the latter being in use throughout the period. This methodology differs from previous studies which quantify diffusion based on the number of steam engines and do not take into account those falling out of use. The results are presented in terms of aggregate, sectoral, and regional patterns of diffusion. Finally, following a long held methodology of the literature on technological diffusion, the paper weighs the number of engines installed by the end of the period in relation to the potential range of adopters. In the end, this method generates a less celebratory assessment regarding the pace of diffusion of Newcomen engines. *The author wishes to thank Alessandro Nuvolari for providing access to the Kanefsky database. Two summer fellowships from the NEH/Folger Institute and Dibner Library (Smithsonian), whose staff was exceptionally helpful (especially Bill Baxter and Ron Brashear), allowed me to draw heavily material from the collection of rare books of the latter. Two graduate students, Lawrence Costa and Michel Dilmanian, proved to be superb research assistants by handling the revisions made by the author to the database, coming up with the graphs, and running the tests involved in the third appendix of the paper as well as writing it. -

Steam As a General Purpose Technology: a Growth Accounting Perspective
Working Paper No. 75/03 Steam as a General Purpose Technology: A Growth Accounting Perspective Nicholas Crafts © Nicholas Crafts Department of Economic History London School of Economics May 2003 Department of Economic History London School of Economics Houghton Street London, WC2A 2AE Tel: +44 (0)20 7955 6399 Fax: +44 (0)20 7955 7730 1. Introduction* In recent years there has been an upsurge of interest among growth economists in General Purpose Technologies (GPTs). A GPT can be defined as "a technology that initially has much scope for improvement and evntually comes to be widely used, to have many uses, and to have many Hicksian and technological complementarities" (Lipsey et al., 1998a, p. 43). Electricity, steam and information and communications technologies (ICT) are generally regarded as being among the most important examples. An interesting aspect of the occasional arrival of new GPTs that dominate macroeconomic outcomes is that they imply that the growth process may be subject to episodes of sharp acceleration and deceleration. The initial impact of a GPT on overall productivity growth is typically minimal and the realization of its eventual potential may take several decades such that the largest growth effects are quite long- delayed, as with electricity in the early twentieth century (David, 1991). Subsequently, as the scope of the technology is finally exhausted, its impact on growth will fade away. If, at that point, a new GPT is yet to be discovered or only in its infancy, a growth slowdown might be observed. A good example of this is taken by the GPT literature to be the hiatus between steam and electricity in the later nineteenth century (Lipsey et al., 1998b), echoing the famous hypothesis first advanced by Phelps-Brown and Handfield-Jones, 1952) to explain the climacteric in British economic growth. -
Water, Air and Fire at Work in Hero's Machines
Water, air and fire at work in Hero’s machines Amelia Carolina Sparavigna Dipartimento di Fisica, Politecnico di Torino Corso Duca degli Abruzzi 24, Torino, Italy Known as the Michanikos, Hero of Alexandria is considered the inventor of the world's first steam engine and of many other sophisticated devices. Here we discuss three of them as described in his book “Pneumatica”. These machines, working with water, air and fire, are clear examples of the deep knowledge of fluid dynamics reached by the Hellenistic scientists. Hero of Alexandria, known as the Mechanicos, lived during the first century in the Roman Egypt [1]. He was probably a Greek mathematician and engineer who resided in the city of Alexandria. We know his work from some of writings and designs that have been arrived nowadays in their Greek original or in Arabic translations. From his own writings, it is possible to gather that he knew the works of Archimedes and of Philo the Byzantian, who was a contemporary of Ctesibius [2]. It is almost certain that Heron taught at the Museum, a college for combined philosophy and literary studies and a religious place of cult of Muses, that included the famous Library. For this reason, Hero claimed himself a pupil of Ctesibius, who was probably the first head of the Museum of Alexandria. Most of Hero’s writings appear as lecture notes for courses in mathematics, mechanics, physics and pneumatics [2]. In optics, Hero formulated the Principle of the Shortest Path of Light, principle telling that if a ray of light propagates from a point to another one within the same medium, the followed path is the shortest possible. -
Steam and You! How Steam Engines Helped the United States to Expand Reading
Name____________________________________ Date ____________ Steam and You! How Steam Engines Helped The United States To Expand Reading How Is Steam Used To Help People? (Please fill in any blank spaces as you read) Have you ever observed steam, also known as water vapor? For centuries, people have observed steam and how it moves. Describe steam on the line below. Does it rise or fall?____________________________________________________________ Steam is _______ and it ___________. When lots of steam moves into a pipe, it creates pressure that can be used to move things. Inventors discovered about 300 years ago that they could use steam to power machines. These machines have transformed human life. Steam is used today to help power ships and to spin large turbines that generate electricity for millions of people throughout the world. The steam engine was one of the most important inventions of the Industrial Revolution that occurred about from about 1760 to 1840. The Industrial Revolution was a time when machine technology rapidly changed society. Steam engines were used to power train locomotives, steamboats, machines in factories, equipment in mines, and even automobiles before other kinds of engines were invented. Boiling water in a tea kettle produces A steamboat uses a steam engine to steam. Steam can power a steam engine. turn a paddlewheel to move the boat. A steam locomotive was powered when A steam turbine is a large metal cylinder coal or wood was burned inside it to boil with large fan blades that can spin when water to make steam.

Steam Engine Use and Development
STEAM ENGINE USE AND DEVELOPMENT A diagram of Cameron's aero-steam engine, from an 1876 dictionary The first industrial applications of the vacuum engines were in the pumping of water from deep mineshafts. The Newcomen steam engine [[12]] operated by admitting steam to the operating chamber, closing the valve, and then admitting a spray of cold water. The water vapor condenses to a much smaller volume of water, creating a vacuum in the chamber. Atmospheric pressure, operating on the opposite side of a piston, pushes the piston to the bottom of the chamber. In mineshaft pumps, the piston was connected to an operating rod that descended the shaft to a pump chamber. The oscillations of the operating rod are transferred to a pump piston that moves the water, through check valves, to the top of the shaft. The first significant improvement, 60 years later, was creation of a separate condensing chamber with a valve between the operating chamber and the condensing chamber. This improvement was invented on Glasgow Green, Scotland by James Watt[[13]] and subsequently developed by him in Birmingham, England, to produce the Watt steam engine [[14]] with greatly increased efficiency. The next improvement was the replacement of manually operated valves with valves operated by the engine itself. In 1802 William Symington built the "first practical steamboat", and in 1807 Robert Fulton used the Watt steam engine to power the first commercially successful steamboat. Such early vacuum, or condensing, engines are severely limited in their efficiency but are relatively safe since the steam is at very low pressure and structural failure of the engine will be by inward collapse rather than an outward explosion. -
Hero's Engine Build Instructions
OMAHA MAKER GROUP Explore Technology, Science, & Art 8410 K Street, #5 – Omaha, NE 68127 [email protected] www.omahamakergroup.org How to Make a Hero’s Steam Engine Description: An easy steam engine (Hero's engine) is constructed from a soda can, some thread, and a heat source. Burning fuel heats the engine to produce steam. The chemical energy in the fuel is converted to a rotation of the can, illustrating the conversion of chemical energy to thermal energy to mechanical energy. Materials: Unopened soda can, thread, a small nail or pin, thread, something to hang the can over the fuel, candle or “Sterno” fuel, lighter, gloves Step 1 Do this outside or over a sink. Use a pin or small nail to make a hole in the side of a soda can. The can must still be unopened. When you pull the pin out there will likely be some spray. Step 2 Empty the can through the pinhole. Depending on the soda in the can, shaking it will increase the pressure in the can causing the soda to come out faster. Don't worry if there's a little soda left when you're done. Step 3 Make another hole in the other side of the can. Step 4 Put the pin back in one of the holes and pull it down as shown in the photos below. This modifies the hole enough for the steam to later come out at an angle with respect to the can. Step 5 Do the same for the other hole, pulling the pin in the same direction with respect to the can. -

Generator in a Combined Cycle Power Plant
1 STEAM POWER PLANT 1.1. INTRODUCTION: A Generating station which converts heat energy of coal combustion into electrical energy is known as steam power station. A steam power station basically works on Rankin cycle. Steam is produced in the boiler by utilizing the heat of coal combustion or burning gases or fuel. Fig 1-1: Diagram of a steam power plant 2 Fig 1-2: Block diagram of a steam power plante 1.2. Power plants: Modern-day boilers, such as those in coal-fired power stations, are still fitted with economizers which are descendants of Green's original design. In this context they are often referred to as feed water heaters and heat the condensate from turbines before it is pumped to the boilers. Economizers are commonly used as part of a heat recovery steam generator in a combined cycle power plant. In an HRSG, water passes through an economizer, then a boiler and then a super heater. The economizer also prevents flooding of the boiler with liquid water that is too cold to be boiled given the flow rates and design of the boiler. A common application of economizers in steam power plants is to capture the waster heat from boiler stack gases (flue gas) and transfer it to the boiler feed water. This raises the temperature of the boiler feed water thus lowering the needed energy input, in turn reducing the firing rates to accomplish the rated boiler output. Economizers lower stack temperatures which may cause condensation of acidic combustion gases and serious equipment corrosion damage if care is not taken in their design and material selection 3 Fig 1-3: Block diagram of a steam power plant Elements of steam power plant: 01. -
