In light of limited oil current state of diesel engine engineering and technol- reserves and the discussion of predicted climate ogy. This makes diesel engines high torque rather than high horsepower, and that tends to make diesel cars slow in terms of acceleration. Diesel Railcar Simulator is a train driving simulator modelling the passenger diesel multiple units, or "railcars", and other trains of the 1960s British railways. Automated boiler controls, along with electric control of throttle and cutoff, could form the heart of MU capability. Also, carbon monoxide (CO) and hydrocarbon (HC) emissions virtually disappear. The engine is manufactured using compacted graphite iron by TUPY. It starts at 0 from 300 RPM, 0.5 at 440, 1 at 1100-1400, 0.77 at 1900, 0.5 at 2400 and falling to 0 at 2600. Diesel locomotives have dynamic brakes, and a modern steam locomotive could utilize compression or “water” brakes. Enclosed find subscription for the Gas Engine Magazine.

Current operating practices and procedures of the railroads were used in the simulations. In addition, the lifecycle costs of the 25NC were cheaper than the comparable SAR diesel. This . The 1949 “Argentina,” was a 2,100 DBHP, 4-8-0 steam locomotive with a  Steam Versus Diesel. Originally the line was built to haul silver ore from the mountains. Found insideSynchronous Generators, the first of two volumes in the Electric Generators Handbook, offers a thorough introduction to electrical energy and electricity generation, including the basic principles of electric generators. In a traditional locomotive firebox, coal is burned with 90 percent primary air coming through the firebed and 10 percent secondary air entering above the fire. “Every locomotive’s different, they like coal in certain places. Figure 1 illustrates such a single . Porta’s two classifications for modern steam locomotives were Second Generation Steam and Third Generation Steam Locomotives. To put it simply, with GPCS, the firebed becomes a gas producer by making it thick. 1500 rpm onward. Dec 10, 2019. Although I'm a Steam buff, and it appears my loyalty is slipping, I One on the left side and the other on the right side of the locomotive. We didn’t get to ride up in the locomotive, but we did get to talk to the people who do. This was demonstrated by a maintenance comparison performed by the Norfolk and Western and Southern Railways. A comparison of modern steam and diesel in the Class I railroad environment Not long after these engines were made, diesels came along. The steam locomotive would have a diesel type cab in the end of the tender, along with compression braking in lieu of dynamic brakes. For a series production diesel engine, a specific torque of … Found inside – Page 49The Diesel engine compares with an ordinary automobile engine in that it has a constant torque , constant speed ... In this instance , some auxiliary means such as steam or compressed air in the cylinders of the Diesel engine was used ... Peak vs Flat Curve Torque. Diesel – Loaded coal from Williamson to Bluefield, WV – Norfolk Southern (5:42:45 This is based on using the relative thermal efficiencies of steam and diesel locomotives and the cost of the fuel input. A large diesel engine usually cannot get above 2,000 RPM, but has huge torque because of the long stroke. It did this for 100 years until the market for silver suddenly dropped. By way of comparison, a modern, high speed 400 hp diesel may produce around 600 pound-feet of torque (measured at the engine's crankshaft output) and weigh somewhere around 1000 pounds. Fire up and prepare for a whole day touring the best of Britain's countryside aboard the Belmond British Pullman or treat an enthusiast to a thrilling train driving taster. If you’re running a railroad, diesels make a whole lot more sense. The other three sections are respectively, throttle, air brake pressure (PSI) With 1:3 the motor needed 20% throttle. This means that a race car engine can run much faster -- up to 15,000 RPM in a Champ Car engine -- but has relatively little torque. The steam engine had made the Industrial Revolution possible, but it was inefficient, bulky, and tiresome to operate. The fire heats the water, the water turns to steam and expands into the piston that cranks the wheels and off you go. The PureTech 130 crosses the line in 1m 18sec. From 1963 to 1986, the South African Railway (SAR) Class 25NC, a locomotive very similar to the N&W Class J, was 20 percent cheaper to maintain than the comparable diesel. Suddenly you could haul tons and tons of goods and passengers far more efficiently than the old way of piling them into a horse-drawn cart. This can be less than the track speed for many reasons, such as train length, recovering from speed restrictions, or stopping to add helpers as in the case of the loaded coal trains from Williamson to Bluefield. Those of you who log high numbers of highway miles on a regular basis or need to tow . There is a limit for the number of cycles per minute that could provide with a steam driven reciprocating . It carries Ken Croft's superb Delong Diesel on the cover, and contained plans for the last of Tom Crompton's EZE engine series (a horizontally opposed CO2 twin), plus construction details for a simple torque reaction device by Giuseppe Tortora. Despite the almost universal application of the internal combusion engine (ICE), the criteria for vehicular power plants are now being seriously reexamined. On fast trains on the BNSF from Clovis to Vaughn, NM, horsepower was equated allowing three steam locomotives to match the performance of four diesels. This is the question that will be weighed here. I am using a retail cost of $15 for … In spite of this, a high efficiency, lower maintenance version of a traditional late US steam locomotive wouldn’t fulfill the requirements of modern US Class I railroads. Also diesel engines tend to be turbocharged. The engine torque responses of six tests with different VGT positions at the second stage (0.5 .

There have been boiler explosions where they’ve found engines thrown a mile away. 899 0 obj <>stream In 2008, the last full year information was available, Powder River Basin (PRB) coal was 15 times cheaper than diesel fuel on a unit of energy basis (one dollar of PRB coal provides 816,327 BTU’s and one dollar of diesel provides 49,322 to 53,729 BTU’s). The collected evidence would show that the steam versus diesel argument is not decided, as conventional wisdom would suggest. This provides the engine optimum strength and . and elevation. The rail line runs up the Animas River Canyon, one of the most scenic railroads anywhere, and finishes in the Old West town of Silverton, which still has most of the 19th century red stone buildings it had back when it was founded. Found inside – Page 1050Current technology probably now permits the development , manufacture , and sale of steam engine systems which have relatively ... weight / horsepower ratios comparable to diesel engines , and greatly superior torque characteristics . Porta developed PT for the Ferrocarril Nacional General Belgrano Railway of Argentina. You can operate a diesel engine for about one third the cost of a coal-fired steam engine. Turbo-charging does contribute enormously to the torque delivery, as it does with a petrol engine. Important benefits can be attributed to the use of PT. 100.66 Miles Miles) With detailed photos, informative text, and intriguing facts, this book will have readers delighted from cover to cover! Finally, while natural gas fumigation for dual-fuel diesel engines has been used widely, as it is much simpler and it can be accomplished through low tech conversions, and thus most vehicles utilize this approach, diesel engines converted to diesel and fumigated natural gas suffer from significant fuel conversion efficiency degradation vs. the original diesel, both full load and part load, and . Today this wouldn’t be the case, due to better design and low fuel cost. Diesel engines tend to produce more smoke and "smell funny." Diesel engines are harder to start in cold weather, and if they contain glow plugs, diesel engines . The answer was the internal combustion … Gas Engine Magazine reader Laurence Graves of Suisun, California starts a conversation about steam engines versus gas powered engines. Hours, I am using a retail cost of $15 for 50lbs of coal and $3.30 for a gallon of diesel. It is possible to run the car on a `rolling road' dynamometer to measure the power output at the driving wheels instead. Derivation of Tractive Force, Single Cylinder Steam Engine Example. In contrast, the BNSF section has moderate grades (0.8 percent); few curves (1 degree); 60-70 mph speed limits with fast trailer and double stack trains. One of the reasons that diesel engines feel more powerful than gas is that they tend to generate more hp at lower RPMs. Stuart A. Bourdon Author. Additionally, engine specific factors such as how recently your oil was changed, whether your engine room is well ventilated, what type of fuel filter you are using and environmental conditions such as humidity, air . the torque of the diesel engine must be great to … The primary reason for diesel engines' torque characteristics are due to high BMEP (Brake Mean Effective [cylinder] Pressure). Antifoams are used to prevent boiler water carryover or priming. This is a very typical locomotive in Class I service today. Durango and Silverton Narrow Gauge Railroad. torque is highest starting out and falls, but always remains at least twice as high as a 4 stroke gas engine at the same speed and rated power. The size of a 30-megawatt steam turbine is same as a 5-megawatt diesel engine. The full load engine torque curve T e [Nm] is characterized by four points: T 0 - engine torque at minimum engine speed T max - maximum engine torque (peak torque or rated torque) T P - engine torque at maximum engine power T M - engine torque at maximum engine speed. Crews must have a cab that is as comfortable as a diesel, and a cab of the same design as a diesel could be fitted to the end of the tender, allowing the same level of comfort for crews. The green line represents the actual speed of the train. The steam locomotives’ higher HP at higher speed gave slightly higher average speeds and about a three percent increase in ton-miles per hour. The Norfolk and Western had two hydraulic ash plants built by United Conveyor Corporation which continues to produce ash handling equipment for the power generation industry.

A serial hybrid, where the diesel engine runs a generator to charge batteries and/or to run the electric drive motor might be very efficient. The size of a steam turbine is much smaller than that of an equivalent diesel engine. Fuel properties Volumetric efficiency Example 4-stroke premixed-charge piston engine 4-stroke premixed-charge piston engine Throttling Throttling Throttling 2-stroke premixed-charge engine 2-stroke premixed-charge engine 2-stroke premixed-charge engine Rotary or Wankel engine Rotary or Wankel engine Rotary or Wankel engine 4-stroke Diesel engine Premixed vs. non-premixed charge engines 2 . The default curve peaks at 1100-1400 (I'd long suspected it was around 1000-1500). The principal specifications of this locomotive are as follows: The 2-8-8-2 is approximately 118 feet for the engine and tender and another 120 feet for both water tank cars. This tractor can produce over 3,000 ft-lbs of torque between 0 and 250 RPM. This model was used to compare the performance and fuel consumption of the 2-8-8-2 and the ES44AC. This method would make it easier for the railway to use existing facilities and maintenance operations without having to create too many new specialised processes. Steam Versus Diesel. A more in-depth study of steam versus diesel would seem appropriate as a first step. 28.18. (H2) and methane (CH4). The use of wood chips from tree farms would be carbon neutral. The steam versus diesel simulation comparisons were made on the Norfolk Southern Pocahontas District between Bluefield and Williamson, West Virginia, and BNSF Railway Clovis Subdivision (a section of the Transcon), between Clovis and Vaughn, New Mexico. The torque profile is like a gas engine's flipped backwards…. Fahrenheit (400 degrees C), coupled with a larger cross section steam circuit that was approximately double the size of traditional recommendations, and a more efficient exhaust design. The … The locomotive cost was estimated by Roger Waller of DLM. Every year, from the beginning of May to the end of October, you can step back in history and get a sense of both life in the early West and of the immense power of expanding steam. Steam locomotives also required costly maintenance. If PT and GPCS are used in concert, even greater maintenance benefits can be had since PT preserves the water side of the boiler in basically “as built” condition, and GPCS largely eliminates the sandblasting effect by unburned coal particles. The Durango and Silverton line is one of the last remaining places in the world where you can see and ride in a real, live steam train. The Norfolk and Western Railway had the most advanced fueling and servicing infrastructure of any railway. Advertisement. ), or by actual testing with drawbar … Delight in a Dining .

The N&W and Southern agreed to develop a maintenance comparison of the then new Class J 4-8-4 and a then new EMD E6. Torque is the effective force to produce rotation. “Basically, you shovel a lot of coal,” said fireman Mark Shelgren. With aircraft engine off it did 60 RPS at 100% throttle and 12 RPS at 20% throttle. A modern steam locomotive for US Class I railroads should be comparable in performance to a GE ES44AC. 868 0 obj <> endobj endstream endobj startxref This is a gallery subpage for Steam Engines vs. Diesel Engines. August 24, 2009 12:08PM. You still have about two more months to get to Durango and have a look for yourself. Steam Engines vs. Diesel Engines/Gallery. It was carried thru the engine & valves by the incoming steam. But improvements in steam technology did not end with Chapelon. Its value remains almost the same or 'flat' across most of the engine speed range (2500-4000 rpm). Why this wasn’t done in the US is another interesting chapter in the story of steam. nicknamed “The Red Devil”. The comparative cost of coal and diesel fuel shows that a coal-fueled locomotive would have lower fuel costs than a diesel-fueled locomotive. The dashed line is the bottom of the coal space angled to the stoker trough. Derivation of Tractive Force, Single Cylinder Steam Engine Example. This would give the steam locomotive a bigger chance of success through being easily operable on the present railway. The use of GPCS allows much higher fuel burn rates than conventional fireboxes. Gas and diesel engines have a torque curve with a prominent peak as you can only achieve that output at a specific level of RPMs that the engine was rated at by the manufacturer. But diesel engines produce way more torque. When the train is starting from a dead stop, the bar is farthest back, when it’s up to speed, it’s farther forward. From the .

Your car, truck or SUV doesn’t have torque until you toss out those measly foot pounds you’ve been measuring in and start measuring output in “tractive effort.” Tractive effort is how steam locomotives measure their output. Also, H. F. Brown of the Institution of Mechanical Engineers produced a study showing that the steam locomotive was significantly cheaper than the diesel in the post World War II US period. Found insideThe book focuses on fuel consumption-the amount of fuel consumed in a given driving distance-because energy savings are directly related to the amount of fuel used. For urban driving, where stopping and starting . Knowing engine RPS and torque is only really useful if this kind of information is available somewhere. The main idea was the use of already existing diesel engine chassis to build the new steam engines. In this volume, noted Columbia University Professor of Architecture Cyril M. Harris offers a unique tour through the entire history of architecture: an extraordinary compendium of clear, concise definitions for over 5,000 important terms. Porta, who died in 2003, developed three very important parts of modern steam: Porta (right) and David Wardale (left) stand beside one of Porta’s last projects, the “Minaz” This idea eventually manifested itself on our shores in the Transcontinental Railway in 1869, linking the Old East with the New West. The water in the boiler will drop below the firebox, which is called the crown sheet, which can then collapse and the entire thing goes up. If there is an image that belongs on this article, please insert it on this page. US Class I railroads need the following attributes that are available in diesel locomotives: automated boiler controls, multiple unit capability, traction control, dynamic braking, distributed power and remote control capability and improved crew comfort versus a traditional steam locomotive. Released. Found inside – Page 1The introduction chapter summarises the book after giving some thoughts on estimating the power, maximum torque and ... The diesel engine replaced the steam engine as the work horse of modern civilization for the past hundred years. -- We now have the ability to configure the torque curve in the engine definition. Shaun McMahon photo. In 2008, the Class I’s had a diesel fuel bill of $12.2 billion, which could be reduced to a $1.3 billion coal bill, resulting in a $10.9 billion cost saving per year.
