2019101 · A fuel tank is also essential. It is interesting to note that the modern diesel locomotive produces about 35% of the power of a electric locomotive of similar weight. Figure 1: A BNSF diesel electric locomotive a GE ES44C4 type, a typical US heavy haul locomotive. Photo: PorsHammer.
201861 · LPD also depends on the number and the weight per axle of the locomotives and passenger cars. Second-by-second (1 Hz) data are available for locomotive speed and acceleration, rail grade, curve
Table 4, Part b shows the average pollutant emission rates per lo- comotive type per hour. 45 to 65% of diesel fuel in China is consumed by tractors, off-road equip- ment, locomotives, vessels and
2014121 · Railway: Fuel Consumption per 1000 Ton Km: Diesel Locomotive. . . 200,20
2009529 · #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 AAR
2019415 · The realistic data for diesel-electric locomotive fuel consumption and emissions for each throttle lever position (so-called Notch position) are adopted from Ref. [38]. This reference presents a comprehensive overview of emission tests for a similarly-sized diesel-electric locomotive from GP38-2 series, also manufactured by the General
The paper analyzes the generation and utilization of rail horsepower in freight train operations. The effects on fuel consumption of variations in several parameters including train consist, car weight, gradient, average speed, meet strategy, throttle control, locomotive axle arrangement, and train marshalling are examined.
III.B.9 Fuel Consumption. The diesel-electric locomotive has a thermal efficiency (percent of useful work derived from a unit of fuel) of 20–25%. Since a gallon of fuel oil contains approximately 130,000 Btu of energy, only 20–25% of this would be available to produce work, that is, pull the train. These values are in contrast to the 5–8%
