Fuel basic engineering

Hydrogen internal combustion engines can be classified, like any other gaseous-fueled engines, into three basic engine concept categories [56] ... 

During the biennium 2003-2004, a conceptual design of interim dry storage for spent fuel assemblies was developed, and at present the basic engineering design is being completed. When it is constructed, spent fuel assemblies will be processed for transfer to the facility. At that time the spent fuel assemblies will be stored under the basic criteria of confinement and retrievability. 

The tasks of basic engineering can be divided into several sequential steps. The first step involves considering some general calculations. The core of a fuel cell system is the fuel cell itself A fuel cell is characterized by its voltage-current characteristics. For stationary applications, a design point must be defined. For... 

Road transport pollution spreads in close proximity to human settlements at high concentrations at low altitudes (Danklefsen 2011) and depends on many factors such as fuel composition, engine type, vehicle maintenance, type and basic characteristics of the vehicle, deployment of infrastructure, speed patterns, routing, congestion, etc. Research on the analysis of emissions under real conditions indicate that certain toxic components of exhaust gases are as much as several hundred percent larger than from non-transport sources for... 

Two types of alcohols were investigated bio-methanol and bio-ethanol. Methanol (methyl alcohol) is used as a solvent (soluble in fats, resins and varnishes), also used in the pharmaceutical component of fuel for aircraft (the main component of fuel), explosives (e.g. C4), as fuel in internal combustion engines such as speedway motorbikes, used with caustic solutions or acids to obtain methyl esters, a basic raw material for polyoxymethylene (polyoxymethylene, polyformaldehyde). Ethanol (ethyl alcohol) is widely used in food and pharmaceutical industries (alcoholic fermentation) and cosmetics it is also used as a solvent. Alcohol may also be used to fuel diesel engines if there are good lubrication injector nozzles and the alcohol is mixed with a small (5-20%) amount of oil. 

The chemical industry represents a 455-billion-dollar-a-year business, with products ranging from cosmetics, to fuel products, to plastics, to pharmaceuticals, health care products, food additives, and many others. It is diverse and dynamic, with market sectors rapidly expanding, and in turmoil in many parts of the world. Across these varied industry sectors, basic unit operations and equipment are applied on a daily basis, and indeed although there have been major technological innovations to processes, many pieces of equipment are based upon a foundation of engineering principles developed more than 50 years ago. 

A fuel cell has two basic elements a fuel delivery system and an electro-chemical cell that converts the delivered fuel into useful electricity. It is this unique combination that enables fuel cells to potentially offer the best features of both heat engines and batteries. Like batteries, the cell generates a dc electric output and is quiet, clean, and shape-flexible, and may be manufactured using similar plate and filmrolling processes. By contrast, the fuel delivery system ensures that fuel cells, like heat engines, can be...
