The Future of Transportation - A Paradigm Shift

2011-04-12
2011-01-1259
Automobile emission is one of the major issues that have been disconcerting this world. Emissions from the automobile, caused by burning the fossil fuels pollutes the environment which after some point becomes irreversible process and destroys the habitat that we share with the other organisms. This paper discusses a unique way to reduce NOx emissions from light- and heavy-duty vehicles (as defined by EPA regulations) by making the roads move instead of vehicles using MEMS cell(s) and/or MEMS Technology and the vehicles can move whenever required. MEMS stands for Micro Electro Mechanical Systems and such systems are generally built on silicon substrate and by process of etching, oxidation and other underlying MEMS mechanism. US DOT (US Department of Transportation) and NHTSA (National Highway Traffic Safety Administration) can also use the concept solely to avoid national and state highway accidents.

The Future of the Closed-Cycle Gas Turbine - A Realistic Assessment

1992-08-03
929013
The first industrial closed-cycle gas turbine (CCGT) plant started service in Switzerland in 1939 and demonstrated the utilization of coal as the fuel, and operation in a combined power and heat production mode, and these were viewed as attributes towards its deployment on a commercial scale. Introduction of further plants in Europe was delayed by two factors: (1) restricted business during the second world war, and (2) the subsequent use of aircraft-derived gas turbines burning oil and gas which were cheap and in plentiful supply. About 15 fossil-fired CCGT plants operated well in Europe (some of them into the 1980s), but both technical and economic factors limited further deployment. The CCGT capability to operate well at high pressure, and with perfect inert gases (e.g., helium) makes it an attractive prime mover for coupling with a nuclear heat source.

580032
THIS paper describes the development and utilization of a new Ford free-piston power-plant, the model 519. Mr. Noren traces the development of the engine from the initial idea to the point where commercial utilization could be considered. Mr. Erwin describes one commercial use: in the Typhoon tractor. The ratio of size and weight to horsepower is favorable for farm tractors, being smaller and lighter than equivalent diesel engines. The performance of the tractor has been satisfactory thus far, operating smoothly and being practically vibration-free, with little noise. The advantages of the free-piston gasifier, as reported by the authors, are: flexibility, fuel economy, no need for auxiliary starting engine, economical manufacture of a wide range of engine sizes, adaptability to a wide range of fuels, and good torque characteristics.

The Future of the Internal Combustion Engine After “Diesel-Gate”

2017-07-10
2017-28-1933
The paper captures the recent events in relation with the Volkswagen (VW) Emissions Scandal and addresses the impact of this event on the future of power train development. The paper analyses the impact on the perspectives of the internal combustion engine, the battery based electric car and the hydrogen based technology. The operation of the United States Environmental Protection Agency (EPA), VW and the United States prosecutor, sparked by the action of the International Council on Clean Transportation (ICCT) is forcing the Original Equipment Manufacturers (OEM) towards everything but rationale immediate transition to the battery based electric mobility. This transition voids the value of any improvement of the internal combustion engine (ICE), especially in the lean burn, compression ignition (CI) technology, and of a better hybridization of powertrains, both options that have much better short term perspectives than the battery based electric car.

The GE90 - Designing for Maintainability

1994-03-01
940022
The purpose of this paper is to describe and illustrate how designing for maintainability in modern ultra high bypass ratio turbofan jet engines has significant cost advantages for both the airline operator and the engine manufacturer. It is also necessary to include in the process of designing for maintainability innovations which optimize the airline's ability to utilize engine assets in the most cost effective manner. Contemporary jet engine design evolved to the degree that major engine functional units could be disassembled without disturbing adjacent units to facilitate maintenance in the engine shop, the familiar modular maintenance concept. This was innovative when developed in the early 1970's but today's 80,000 pound thrust class engines require new initiatives.
