Electric Propulsion System Overview A Propulsion System That Outrivals Conventional Propulsion Engines in Efficiency and Functionality. In conventional power system arrangements, the ship's propellers are driven by a diesel propulsion engine while the supply of electricity for the other shipboard loads is transmitted via the shipboard generators.
Diesel engine fuel-injection systems are typically designed to provide injection pressures in the range of 7 to 70 megapascals (1,000 to 10,000 pounds per square inch). There are, however, a few higher-pressure systems. Precise control of fuel injection is critical to the performance of a diesel engine. Since the entire combustion process is controlled by fuel injection, injection must begin ...
Introduction to Diesel Electric Power Plant: Diesel electric power plant is a power plant in which a diesel engine is used as the prime mover for the generation of electrical energy. The diesel engine obtains energy from a liquid fuel usually called the diesel oil and converts it into mechanical energy. An alternator or a dc generator mechani ...

A diesel, on the other hand, produces all its torque down low--as does an electric motor. That means a diesel hybrid should have boatloads of torque off …
While this book can certainly stand alone as an introduction to diesel-electric locomotives, prior knowledge of at least the basics of motive power proves helpful to understanding the workings of locomotives, and the myriad ways that fuel economy and fuel use can be improved. Concern about global warming and decreasing humankind's carbon ...
Compared to direct diesel drives, diesel electric propulsion systems are technically and operationally superior in virtually all applications. This superiority has been a major reason for the steadily growing demand for diesel-electric main drives in marine engineering applications. Introduction:
Introduction. Centrifugal pumps basically consist of a stationary pump casing and an impeller mounted on a rotating shaft. The pump casing provides a pressure boundary for the pump and contains channels to properly direct the suction and discharge flow. The pump casing has suction and
The diesel power plants are installed where the supply of coal and water is not available in sufficient quantity or where power is to be generated in small quantity or where standby sets are required for continuity of supply such as in hospitals, telephone exchanges etc.. These plants in the range of 2 to 50 MW capacity are used as central stations for small supply authorities and works.

Examples of new uses for electric power include all manners of electric transportation systems (electric trains that run under catenary, diesel-electric railroad locomotion, 'maglev' medium and high speed tracked vehicles, electric transmission systems for ships and diesel-electric locomotives, replacement of hydraulics in high performance ...
Diesel electric drives found a natural application in submarines and many surface ships. Today's cruise ships, where 70-80 percent of the total onboard power is required for the "hotel" side of the vessel, are diesel electric powered. The power demands can be enormous at times. A trivial example: 1,500,000 watts, equal to more than 1,400 hp, is ...

population of diesel-powered automobiles, the amount of diesel fuel produced exceeded the production of gasoline by just over 1.7 billion gallons.4 The term "diesel fuel" is generic; it refers to any fuel for a compression ignition engine. In common use, however, it refers to the fuels made commercially for diesel-powered vehicles.
