19 Facts About Diesel locomotive
2.
Rudolf Diesel patented his first compression-ignition engine in 1898, and steady improvements to the design of diesel engines reduced their physical size and improved their power-to-weight ratios to a point where one could be mounted in a locomotive.

6.
The second milestone, and the one that got American railroads moving towards diesel, was the 1938 delivery of GM's Model 567 engine that was designed specifically for locomotive use, bringing a fivefold increase in life of some mechanical parts and showing its potential for meeting the rigors of freight service.

8.
The power positions are often referred to by Diesel locomotive crews depending upon the throttle setting, such as "run 3" or "notch 3".

9.
Therefore, the net power produced by the Diesel locomotive will remain constant for any given throttle setting.

10.
Hence, the traction motors will produce their highest torque, causing the Diesel locomotive to develop maximum tractive effort, enabling it to overcome the inertia of the train.
| FactSnippet No. 1,662,192 |
11.
Dynamic braking takes advantage of the fact that the traction motor armatures are always rotating when the Diesel locomotive is in motion and that a motor can be made to act as a generator by separately exciting the field winding.

12.
Diesel locomotive–hydraulic drive is common in multiple units, with various transmission designs used including Voith torque converters, and fluid couplings in combination with mechanical gearing.

13.
Diesel-pneumatic locomotive was of interest in the 1930s because it offered the possibility of converting existing steam locomotives to diesel operation.
| FactSnippet No. 1,662,195 |
14.
The frame and cylinders of the steam locomotive would be retained and the boiler would be replaced by a diesel engine driving an air compressor.

15.
Flameproof diesel locomotive has replaced the fireless steam locomotive in areas of high fire risk such as oil refineries and ammunition dumps.
| FactSnippet No. 1,662,197 |
16.
Latest development of the "Flameproof Diesel locomotive Vehicle Applied New Exhaust Gas Dry Type Treatment System" does not need the water supply.
