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. -

7/11/2018 #PIP4753: Supplement To Upper Engine And Fuel Injector Cleaner Label - (Dec 11, 2009) • 2003 GMC Truck Yukon 4WD • MotoLogic 2003 Yukon 4WD Report a problem with this article Subject: Supplement to Upper Engine and Fuel Injector Cleaner Label All GM Vehicles Models: Equipped with a Gasoline Engine The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI. Condition/Concern: Some service procedures, service bulletins, or PIs may advise to decarbon the engine with GM Upper Engine and Fuel Injector Cleaner to remove valve deposits but the label that is on the back of the bottle does not include any instructions that explain how to use the cleaner. Recommendation/Instructions: If a service procedure, service bulletin, or PI does not include decarboning instructions and the GM Vehicle Care 3 Step Induction Cleaning Kit (E-957-001) is not available, the guidelines below supplement the label and explain how the cleaner can be used to clean the intake valves: Important: Extreme care must be taken not to hydrolock the engine when inducing the cleaner. If too much cleaner is induced at too low of a RPM, or if you force the engine to stall by inducing too much cleaner at once, the engine may hydrolock and bend a connecting rod(s). 1. In a well-ventillated area with the engine at operating temperature, slowly/carefully induce a bottle of GM Upper Engine and Fuel Injection Cleaner into the engine with RPM off of idle enough to prevent it from stalling (typically around 2,000 RPM or so). -
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. -
Heyside Signals and Locomotives Three Etched Brass Footbridge Kits
The Lancashire & Yorkshire Railway Society The Lancashire & Yorkshire Railway Society sections; Cynric did the CAD work, and a short while later, I was presented with Heyside signals and locomotives three etched brass footbridge kits. Since the article on the 7mm scale layout Heyside in Magazine 251 there have been continuing The footbridge made up exactly as developments, both on the signalling side and in additions to the locomotive fleet, as its owner intended, fitting the space perfectly, RICHARD LAMBERT, who also took the layout photographs, explains… and providing a sound base to mount the signals. The signals themselves are made from wood, with etched and cast components from Scale Signal Supply for the fittings. The decking was made of copper-clad strip, stanchions from nickel- coated brass lace pins and the various brackets and smoke shields from brass sheet. The operating wire is 0.4mm nickel silver and the operation is by servos mounted under the baseboard. The gantry This was felt to be the signature piece of the layout with five dolls and nine arms. It is based on the gantry outside Victoria East Junction signal box and illustrations in the Society’s Focus on Signalling (No.3). The legs are made of wood, with brass ‘X’ pieces, while the support for the decking is four strips of brass. The decking itself is made from 84 P4 copper-clad sleepers, while the spandrels were commissioned by me from Scale Signal Supply. The dolls and hardware were built as before, but it was in the operation of the signals that most thought had to be given. -

In comparison with other counties, Cornwall was characterized by a relative high price for coal which was imported from Wales by sea.2 It is not surprising then that, due to their superior fuel efficiency, Watt engines were immediately regarded as a particularly attractive proposition by Cornish mining entrepreneurs (commonly termed ‘adventurers’ in the local parlance).3 Under a typical agreement between Boulton and Watt and the Cornish mining entre- preneurs, the two partners would provide the drawings and supervise the works of erection of the engine; they would also supply some particularly important components of the engine (such as some of the valves). These expenditures would have been charged to the mine adventurers at cost (i.e. not including any profit for Boulton and Watt). In addition, the mine adventurer had to buy the other components of the engine not directly supplied by the Published by & (c) The Newcomen Society two partners and to build the engine house. -

When, ten days ago, the first copy of the " Evolution of the Steam Locomotive" was ready for sale, I did not expect to be called upon to write a preface for a new edition before 240 hours had expired. The author cannot but be gratified to know that the whole of the extremely large first edition was exhausted practically upon publication, and since many would-be readers are still unsupplied, the demand for another edition is pressing. Under these circumstances but slight modifications have been made in the original text, although additional particulars and illustrations have been inserted in the new edition. The new matter relates to the locomotives of the North Staffordshire, London., Tilbury, and Southend, Great Western, and London and North Western Railways. I sincerely thank the many correspondents who, in the few days that have elapsed since the publication: of the "Evolution of the , Steam Locomotive," have so readily assured me of - their hearty appreciation of the book. rj .;!
