Before the invention of precombustion chamber injection, air-blast injection was the only way a properly working internal air fuel mixture system could be built, required for a Diesel engine. During the 1920s, [2] air-blast injection was rendered obsolete by superior injection system designs that allowed much smaller but more powerful engines. [3]
A British Rail Class 185 diesel hydraulic multiple unit operated by TransPennine Express at Manchester Piccadilly station, United Kingdom. A diesel multiple unit or DMU is a multiple-unit train powered by on-board diesel engines. A DMU requires no separate locomotive, as the engines are incorporated into one or more of the carriages.
In engineering terms, three-point attachment is the simplest and the only statically determinate way of rigidly joining two bodies. A three-point hitch attaches the implement to the tractor so that the orientation of the implement is fixed with respect to the tractor and the arm position of the hitch.
A PTO at the rear end of a farm tractor A PTO (in the box at the bottom) in the center of the three-point hitch of a tractor. A power take-off or power takeoff (PTO) is one of several methods for taking power from a power source, such as a running engine, and transmitting it to an application such as an attached implement or separate machine.
4 ft 8 + 1 ⁄ 2 in (1,435 mm) The GWR autocoach (or auto-trailer ) is a type of coach that was used by the Great Western Railway for push-pull trains powered by a steam locomotive . The distinguishing design feature of an autocoach is the driving cab at one end, allowing the driver to control the train without needing to be located in the cab ...
A refueling Fast Fill System allows speedy and safe refueling for many types of equipment. This includes mining, heavy construction, busses and railroad. Most larger earthmoving and mining vehicles with diesel fuel tanks over 150 US gallons (570 L) are equipped with a refueling Fast Fill System. These refueling Fast Fill Systems utilize an ...
Over a period of time, Detroit Diesel continued to further evolve the design of the engine. They finally brought the engine up to 137.5 hp (102.5 kW) per cylinder and 406 lb⋅ft (550 N⋅m) torque per cylinder; needless to say, this is a considerable amount of power coming from 149 cu in (2.4 L) per cylinder.
The AAR wheel arrangement system is a method of classifying locomotive (or unit) wheel arrangements that was developed by the Association of American Railroads.Essentially a simplification of the European UIC classification, it is widely used in North America to describe diesel and electric locomotives (including third-rail electric locomotives).
