Diagram of Priestman oil engine from The Steam engine and gas and oil engines (1900) by John Perry Petrol–electric Weitzer railmotor, first 1903, series 1906. The earliest recorded example of the use of an internal combustion engine in a railway locomotive is the prototype designed by William Dent Priestman, which was examined by William Thomson, 1st Baron Kelvin in 1888 who described it as ...
The octane rating of n-butanol is similar to that of gasoline but lower than that of ethanol and methanol. n-Butanol has a RON (Research Octane number) of 96 and a MON (Motor octane number) of 78 (with a resulting "(R+M)/2 pump octane number" of 87, as used in North America) while t-butanol has octane ratings of 105 RON and 89 MON.
Part of the EMD Dash 2 line, the SD45-2 was an upgraded SD45.Like the SD45, the SD45-2 had an EMD 645E3 20-cylinder engine producing 3,600 horsepower (2,680 kW). The main spotting difference between an SD45 and an SD45-2 was the long hood and the rear radiator.
The SD45T-2 is a model of diesel-electric locomotive built by EMD for the Southern Pacific Railroad.Like the later SD40T-2 it is colloquially nicknamed a tunnel motor. 247 total units (including the original EMD/SP joint venture working Prototype) were produced from February 1972 to June 1975, including 84 for SP's subsidiary Cotton Belt.
OPE1A [ru; uk] industrial electro-diesel locomotive for quarry railways with primary electric locomotive and two diesel B–units. An electro-diesel locomotive (also referred to as a dual-mode or bi-mode locomotive) is a type of locomotive that can be powered either from an electricity supply (like an electric locomotive) or by using the onboard diesel engine (like a diesel-electric locomotive).
Power was provided by twin 900 hp (670 kW) 12 cylinder Winton 201-A diesel engines in each power unit, exceeding by 50% the most power that could be attained with a single engine at that time. The added "headroom" in power extended the life of mechanical parts, which was a critical issue with early diesel engines in locomotives.
Dieselisation (US: dieselization) is the process of equipping vehicles with a diesel engine or diesel engines. [ 1 ] It can involve replacing an internal combustion engine powered by petrol (US: gasoline) fuel with an engine powered by diesel fuel , as occurred on a large scale with trucks, buses, farm tractors, trains, and building ...
A steam diesel hybrid locomotive is a railway locomotive with a piston engine which could run on either steam from a boiler or diesel fuel.Examples were built in the United Kingdom, Soviet Union and Italy but the relatively high cost of fuel oil, or failure to resolve problems caused by technical complexity, meant that the designs were not pursued.
