Does anyone have this info on GE FDL's, or ALCo 251 and 244 prime movers? So apparently it takes 25 gal/hr to run a 16-645 at full speed with next to no load. for one thing the E units were 2-567 engines not just the 1 that were in hood units. Revision 3: Makes it just right A locomotive or engine is a rail transport vehicle that provides the motive power for a train.If a locomotive is capable of carrying a payload, it is usually rather referred to as a multiple unit, motor coach, railcar or power car; the use of these self-propelled vehicles is increasingly common for passenger trains, but rare for freight (see CargoSprinter and Iron Highway). So, the train moved 436 tons 1 mile on 1 gallon. On newer SD40-2s, they don't rev up in dynamics until about position 6 or so. The amount of fuel-dependency and the maintenance issues which come along with diesel engines are the primary reason for this. For hydrogen, the LHV is about 50,000 BTU/lb and the HHV is about 60,000 BTU/lb (where lb is a pound mass). It just means there's finally just enough energy in the exhaust stream to allow the turbine to power the compressor. It takes LOTS of effort on the pedals to accelerate if you don't get it into a lower gearing.) Other cases are much much different. The power producing capability of the turbo engine is nearly flat once you get past notch 2. Turbo's seem more economical because they only produce usable boost when under a load. A diesel engine produces 30 percent more work and only produces 2.5 percent more CO2 for that gain. So: Total fuel consumed round trip = 20,000 gallons. That is per locomotive, so, if you have four newer locos in the consist, multiply 165 by 4, and you are consuming 660 gal/hr. therefor more fuel used to make the 2250 horsepower. I spent a lot of time doing fuel consumption testing on locomotives - I have the #2 diesel-soaked work boots to prove it - so let me see if I can explain some things. A fair comparison would be two otherwise identical locomotives, one with a turbo, one with a blower. In that round trip, the train will refill twice, each time each locomotive taking on about 4,000 gallons. Fuel Specific Gravity - .845. On a GP38/40-2 it consumes 81 HP at 900 engine RPM and since fan HP goes up with speed squared, reducing the speed saves quite a bit of energy. Weight and dimensional increase outcomes are usually not acceptable in the highly restricted weight/dimensional envelope in a rail application. Consider these facts to help you decide between an engine powered by diesel fuel and a gasoline-powered one: PRO: Diesels get great mileage. Nothing is worth taking the risk of losing a life over. That's the only delivered power that matters. Revision 1: Adds this new piece Maintenance: You would think this may be a no-brainer, but you would be surprised by the number of trucks that pass through our shop that run completely different after we give it a full service. Our community is FREE to join. The [dynamic braking] excitation comes from the main generator (or traction alternator). If you’re considering buying a new automobile, compare the pros and cons of diesel-powered vehicles. And because of the debut of its AC-traction counter-part; the more popular ES44AC, orders weren't placed until the following year due to a lack of interest from most railroads whom preferred AC-traction motive power as opposed to the more tradit… Mike WSOR engineer | HO scale since 1988 | Visit our club www.WCGandyDancers.com. But I guess it was a lot simpler, safer, cheaper, easier to generate the traction-motor-as-generator excitation voltage with the main generator during dynamic braking and hence dynamic braking uses a little bit of fuel. A number of the early Alco and Baldwin engines were naturally aspirated. Barometric Pressure – 29.92” Hg. Engineer qualification?, wind? The 567 series engine was a 2-stroke diesel, I do believe the 645 was a 4-stroke. Safety begins with ME.... cinscocom-west. http://blerfblog.blogspot.com/). Here's an example that may help. Mileage is not a figure used in trains, it is gallons of fuel burned per hour, the tonnage of a train varies so much from one to another that mileage would not be any kind of a valid figure. An SD40-2 doesn't deliver 3,100 hp. This service offers a point to point distance calculation between locations on the Great Britain railway network. Two other things also crossed my mind. The route is mountainous throughout, with numerous long ascending grades. On day 1, it starts its work with a full tank. Fuel Economy and Diesel Engines . Most locomotives are equipped with a 4,200 gallon fuel tank, and this is usually enough to cover 1,000 miles on the older equipment. Diesel engines also operate at lower speeds (rpm) than gasoline engines, which means the bearings, piston rings, cylinder walls, valve train, etc., don’t rub together as often. Here's some dated information on the SD-40 from "Fuel Efficiency Improvement in Rail Freight Transportation," J N Cetenich, FRA-ORD-76-136, Dec, 1975. Other, less stressed, services have longer mileage intervals. Re: 2 stroke vs. 4 stroke. When that 645T engine is sitting there idling there is no usable boost from the turbo's and the engine therefore reacts like it's a regular, non turbocharged 8 cylinder. If GM "killed the electric car", what am I doing standing next to an EV-1, a half a block from the WSOR tracks? That can't have done much for the fuel economy, either. Then again I would say that anyway since I am a train person. This efficiency might be stated as “a train can move a ton of freight 492 miles on a gallon of fuel.”. The engine manufacture typically has empirical correction curves compliled from actual test data that you can use to correct from what ever your test conditions are back to standard. … As old diesel trains are phased out of rail networks around the world, the UK is about to test a new type of engine that could help to decarbonise railways – … increased longevity. A significant improvement over the old SD45s and their 196 gallon per hour thirst. Availability rates that are prime-mover related have more than quadrupled in improvement in my career. The “Ton-Miles of Freight” annual value is reported in Schedule 755, line 110 of the R1 Report. For example, say that a train with a 3000 gal. longevity. The 2018 CSX system-wide train efficiency metric equals: 208,712,027,000 ton-miles / 423,998,863 gallons = 492 ton-miles per gallon. why does using the dynamic brake cause an increase in fuel usage? The 660 HP 539 engine in the Alco S-1 had no turbocharger. Consuming 4,062,025,082 gallons of diesel fuel (including freight trains and trains in switching yards, but excluding passenger trains) The average works out to … "If you need a helping hand, you'll find one at the end of your arm.". I don't specifically know why E units had such relatively awful fuel economy. Diesel locomotives are slowly disappearing from the Indian Railway scene. Data source: International Association of Railway Operating Officers Efficient use of fuel means fewer greenhouse gas emissions for our planet. In order to get high fuel efficiency, the hull shape needs to be more needle-like. fuel tank travels 100 miles each day, every day. While it's true “Idling is one of the main reasons a fleet manager would want to track hours instead of mileage,” said Kooken of PHH Arval. Anthracite and coke would have an HHV only marginally larger than the LHV. #2 Diesel fuel:  In order to  rate the fuel consumption and output of diesel engine in any meaningful way, you need a set of standard conditions. Similarly, a typical train might haul 3,000 tons of freight 500 miles and consume approximately 3,049 gallons of diesel fuel. and/or accepting a much higher maintenance cost and much lower engine Another way of obtaining an average is to use the US Energy Information Administration's averages for the U.S. as a whole. The table you cited is interesting. The blower engine gets really lousy in the upper notches and notch 8 is horrendous. That's exactly what I was thinking (about the 2 separate 567's in each E) as I read through this thread. That creates enormous resistance to motion through the water. (Learn more at the Association of American Railroads’ website, http://www.aar.org/. The other point is that, if I recall my physics correctly, wind resistance increases proportional to the SQUARE of the speed, so to go 10% faster, you'll feel about 21% more wind resistance, and to go 40% faster (like about the difference between "freight" speeds and "passenger" speeds), you'll feel almost double the wind resistance (actually about 96% more.) A diesel locomotive is a type of railway locomotive in which the prime mover is a diesel engine. CSX trains can move a ton of freight approximately 492 miles on a single gallon of fuel. Somewhere between notch 6 and 7 the gear train fraction finally reaches zero. Subscribe to receive Customer Service Advisories. Even outboard motors have cut fuel consumption rate by about 30% by going to direct inject. Not only was energy required to drive the air compressor, but a refrigerating effect that delayed ignition occurred when the compressed air, typically at 6.9 megapascals (1,000 pounds per square inch), suddenly … Similarly, a typical train might haul 3,000 tons of freight 500 miles and consume approximately 3,049 gallons of diesel fuel. total displacement increases, because the engine designers want to live How many days later would it need a refuel? The difference is that the work you would have had to supply from the gear train in on a blower engine, you get almost for free on the turbo. What the AC traction motor locos do is something I don't know. Each locomotive carries 5,000 gallons of fuel. Welcome to the new version of the RailMiles Mileage Engine. This shows very well how efficient the different modes of transportation really are. those advances to improve longevity and reduce maintenance cost, rather For example, a heavy-duty diesel truck hauling 19 tons of freight a distance of 500 miles would consume approximately 71 gallons of diesel fuel, assuming an average 7 miles per gallon truck fuel economy and a typical truck payload of 19 tons. The rail industry also tracks and reports annual fuel usage in the R1 Report, Schedule 750, line 4. Beyond that, the blower engine starts to "lose its breath" as the blowers have trouble keeping the airbox supplied. That vehicle idles for hours each day while the crane is up. The fuel consumption rate for many makes of Diesel Engines can be found in a range between 0.380 & 0.450 lbs/hp hour; 172 & 181 grams/hp hour; 231 & 243 grams/kW hour. And just as a side note, back in the early 90's when Dodge/Plymoth came out with the Neon, it was originally planned to have a 2-stroke 4 cylinder engine, instead of the dumb junky 2.0L 4-stroke crapola it had. Surprised that water uses more fuel then rail. Now even if an engine operates for long periods at a constant speed it seldom operates at its full rated power. Its somehow assumed that spark ignited- loop scavenged engine in outboard motors , chain saws and weed wackers are indicative of thermodynamic performance of 2 stroke diesel. Acting as generators they act as brakes. Notice that both locomotives are worse incremental power producers as you move the throttle out. This is not perpetual motion as you are still converting shaft power to electric power, and you may need some initial excitation or magnetism in the field to get this going. than hold those even and obtain higher horsepower, because that's what • Locomotive Tier 4 emissions regulations, compliance technologies, and their impact on fuel economy. CSX has invested more than $2.8 billion over the last decade to improve its locomotive fuel efficiency and reduce the corresponding emissions. Also notice that both locomotives are close to identical in efficiency up through notch 4. Diesel engines have about half the useable rpm range as compared to a gas engine. According to EMD, the SD40-2 consumed 164.4 gph at 3,000 hp output into the flywheel, similiar to the table you cited, but the E8 consumed 188 gph at 2,250 hp into its flywheels instead of the 114 you cite. With expensive fuel one could pursue alternatives to this arrangement, but given the costs and benefits it may not be worth it. 12 different engines are available in a wide range of horsepowers, including V12 and V16 configurations. “Take an electric company truck, for example. Interestingly, an E8 burned 114 gal/hr at run 8. These two reported values are used to determine a system-wide train efficiency value. Diesel engine - Diesel engine - Fuel-injection technology: One objectionable feature of the full diesel was the necessity of a high-pressure, injection air compressor. CEO,COO,CFO,CMO,Bossman,Slavedriver,Engineer,Trackforeman,Grunt. As others said above, everything depends on the route, speed, and weight of train! Looking back at the rack on the governor, though, shows about notch 2. This efficiency might be stated as “a truck can move a ton of freight 134 miles on a gallon of fuel.”. In Idle, a large diesel locomotive burns maybe 5? The efficiency of this freight haul would be calculated as: (19 tons x 500 miles) / 71 gallons = 134 ton-miles per gallon. • Locomotive fuel economy technologies and the energy efficiency performance measures kept confidential by the railroad industry. See the chart below (I hope it's legible - appologies for using Traction HP instead of Brake HP). ), Here is the formula for our 2018 fuel efficiency rating: (From the 2018 CSX R-1 Report), • Schedule 750, Lines 1+3 (Line 4), Diesel Fuel Consumed (freight + switching) = 423,998,863 gallons, • Schedule 755, Line 110, Revenue Ton-Miles = 208,712,027,000 RTM, • RTM per gallon = (208,712,027,000 RTM / 423,998,863 gals) = 492 RTM/gal. Dynamic braking:  There were two right answers here. Fuel economy may vary as much as 5 mpg in a given vehicle with different drivers." What does this mean for engine efficiency? I heard that the uniflow principle was patented about 1930 by General Motors after experiments by Charles Kettering's bunch. At any rate 4 strokes are way more fuel effiecent. The hybrid diesel locomotive is an incredible display of power and ingenuity. According to the AAR, moving freight by rail is 4 times more fuel efficient than moving freight on the highway. I may be inferring incorrectly, but allow me a comment on that. rail customers usually want. the 567, and 710 over 645, in terms of reduced engine maintenance cost and More likely it's transmission inefficiency. The AAR standards for locomotive diesel engines are: Barometer - 28.86" Hg (typical for 1000' above sea level - which makes Altoona a great place to do tests). And the amount of CO2 produced by the diesel engine is only 2.5 percent greater. IIRC, an SD40-2 consumes about 195 gallons/hour in RUN 8. This is provided with no warranty and is for your own personal use only.If you wish to use this service for commercial purposes, please contact the Realtime Trains Data Feeds team.. If you want the most efficiency out of your diesel pickup, you need to make sure every vehicle system is working properly. within a certain maximum pressure within the cylinder that's commensurate with the capabilities of the design to resist that pressure. Revision 4: Removes it. If an engine is running 'all out' in RUN 8 for hours, with only crew change service stops every 3-4 hours, we can get a typical fuel consumption number. A particular coal train I have worked with runs 1,670 miles round-trip between the mine and the power plant. Not sure of when the change was made, but it was after the test (1975) and before 1978. I think no.2 diesel is about 7.04 pounds per gallon. This 270,000-pound (122,470-kg) locomotive is designed to tow passenger-train cars … MU'd/DPU'd with? In this example, the train is approximately 3.7 times more efficient at hauling freight, as shown by the ratio 492 train ton-miles per gallon divided by 134 truck ton-miles per gallon. There is little if any improvement with turbocharging and the 645-series engine with the SD40. Mudchicken The Evolution Locomotive is the most advanced, fuel-efficient, and environmentally clean diesel locomotive in history. That 436 mile trip used 436 gallons, or more. axle count? You should read "EMD/ General Motors" and "Turbocharged/ Supercharged" below in this section for a pretty good discussion. Despite having an initial debut in early-2003, the model didn't officially begin production until the US EPA's "Tier 2" policy became under full effect in 2004-2005. Horsepower per cubic inch of displacement in an engine family often doesn't increase when By signing up you may also receive occasional reader surveys and special offers from Trains magazine.Please view our, Get our weekly newsletter delivered to your inbox, http://rr-fallenflags.org/manual/manual.html, Turbocharging increased fuel economy by 12-15%. I can't think of any 4-stroke locomotive prime movers that did not have turbochargers. My WAG on conclusion #2 is that the fuel consumption may include the steam generators, otherwise I'd also wonder what was killing the fuel economy of the E's. JC08 Cycle New urban driving cycle for emission and fuel economy measurements of light-duty vehicles, which will fully replace the 10-15 mode cycle by 2011. Speed points. Heavy-Duty Engines And Vehicles 6-Mode Cycle Wow. Tonnage? I'd wager that conclusion #1 holds more for the 2 cycle engines, and would assume 4 cycle engines would have a smaller increase in fuel economy. There is very little variation notch to notch. In other words, CSX trains, on average, can move a ton of freight nearly 500 miles on a gallon of fuel, based on our 2018 revenue ton miles and 2018 fuel use. The ton-mile-per-gallon is a unit of measurement used to describe the efficiency of hauling freight by various modes of transportation. It doesn't matter if its a 6.0L diesel from a GM truck or a 197L diesel from turbocharged V8 train prime mover, it works the same. For example, in 2018, the CSX ton-miles of freight reported in the R1 Report = 208,712,027,000 ton-miles and the CSX 2018 combined line haul and switcher reported fuel usage = 423,998,863 gallons. I may not know alot about trains, but I do know alot about engines. 1. Depending on speed limits, profile and load, mpg depends not only on the time spent in each throttle position during running, but also in idle between runs. Urban driving cycle for emission certification and fuel economy determination of light-duty vehicles. ** Low idle 4.1. #2 Diesel fuel: In order to rate the fuel consumption and output of diesel engine in any meaningful way, you need a set of standard conditions. The diesel engine has a relatively narrow rpm range that will produce acceptable fuel economy. The efficiency of this freight haul would be calculated as: (3000 tons x 500 miles) / (3,049 gallons) = 492 ton-miles per gallon. The unit is coupled to six traction motors, one on each axle. semi-trailer combination is getting 8 mpg to move 26 tons of freight, the average train is getting 66 mpg to move 26 tons of freight. The fuel efficiency for a freight truck can be estimated in a similar way. Air Intake Temperature – 60°F. When running on the mainline, both the battery-electric and diesel locomotives will power the train. Birdsboro & Reading Railroad. In other words, for every 6.5 to 7.5 miles, a gasoline-powered vehicle travels on a gallon of fuel, a diesel powered engine will travel 10. Are they all in the same range, or does it vary? As engine output increases on a turbo engine, the fraction of the power from the turbine increases and the fraction from the gear train decreases. One is that the E's had traction motors geared for the higher "passenger speeds", which probably would have required a bit more effort to make them turn against that higher gear ratio (Ever try to pedal a 10-speed bicycle when it's in too high of a gearing and without downshifting? of diesel fuel: ~500 miles BNSF Railway is one of North America’s leading freight transportation companies, with a rail network of 32,500 route miles in 28 states and three Canadian provinces. Most Diesel/Electric Locomotives hold 2,000 gallons of fuel. Like Rango said we don't use a miles per gallon figure to calculate fuel burn.But It can be done .Keep in mind that many things can affect the number you'd get.My last train home was a 7,000 ton inter-modal train with four locomotives on it.Each engine burned about 350 gallons of diesel to move 230 miles.If you do the math you get a figure of 6/10ths of a mile per … EMD blower vs turbo:  A biggie! A gasoline engine will produce acceptable fuel economy over a fairly wide rpm range. However, that mechanically driven TM blower is a HP hog. They have to rev the engine some to run the generator -- this is needed to produce what they call excitation voltage for the traction motors so they act as generators. I am not sure how you have reached that conclusion, which is contrary to my experience and knowledge. There is no "magic" when the turbo gets off the clutch. What I would like to know is why does using the dynamic brake cause an increase in fuel usage? The fuel saving  from turbochargers on EMD two stroke engines came from the turbocharger uncoupling from its gear drive from the crankshaft at notch 7 (or about). gallons per hour. This does not represent a big difference in fuel consumption per power unit between most normal naturally aspirated diesel engines, while turbocharged engines are not significantly better. Wow, that is something I have to look into. But I think what you're looking for is averages. I have seen varying accounts, I do know that railroads sometimes ordered larger fuel tanks to get longer distances out of their engines. that engine technology improves over time, often designers want to use The trip was not 436 miles on one gallon, as suggested. How far does the average diesel locomotive go between refuels, and how many MPG does it get? Size of fuel tank - anywhere from 2600 gallons to 5000 gallons are typical capacities. A major part of the reason why the governent started saying everything from a car to 10cc weed eater should be a 4-stroke design engine. Some older SD40-2s have been rebuilt/upgraded with this feature. It goes without saying that the most fuel … Still a Fossil Fuel, However The largest diesel engine is the 109,000 hp Wartsila engine which is 2 stroke, uniflow scavenged 2 stroke diesel with the lowest bsfc of .260 lb per hp-hour. At $2.75 per gal for fuel, the consist is drinking $1850 worth of diesel … This is why shutting down is such a big issue. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. Perhaps one reason for uisng using (did my keyboard ever foul up on that!) The AAR standards for locomotive diesel engines are: Air temp - 60 deg F. Fuel temp - 60 deg F. Barometer - 28.86" Hg (typical for 1000' above sea level - which makes Altoona a great place to do tests) They typically deliver 25 to 30 percent better fuel economy than similarly performing gasoline engines. Mileage isn’t being recorded during this time, but one hour of idling is equal to 25-30 miles of driving. Granted, they would still go through the various transition points at lower speeds, but once they got up to their "highest" setting, they were still working against those higher traction-motor gear ratios. Under most conditions, the engine speed needed for cooling air is greater than that needed for excitation and N4 was a "one size fits all" solution. Of course the idea is that the train is moving a lot more tonnage than another form of transportation with the same fuel, so its more efficient. So you need to make some guesses about how much time it's spending idling and how much at full power, and how fast it's covering the miles. Diesel engines are also built heavier than a gas engine to sustain the added stress of the higher compression ratio. The difference between Low Heating Value and High Heating Value is the latent heat of condensing the water in the combustion gases. I don't know, maybe type of train would make a difference too, but the more knowlegable members here certainly can answer this better. Old age I guess. We always had a lab run a HHV test on the fuel we used for testing.
