The Future of OBD: Enhanced On-Board Diagnostic System with Remote Access

2022-03-29
2022-01-0114
Vehicle manufacturers and their suppliers are legally mandated to develop low-emission engine technologies. Type approval for road-vehicles or non-road mobile machines is only granted when the limits for carbon monoxide (CO), nitrogen oxides (NOx), hydrocarbons (HC), and particulate matters (PM) are observed. In addition to complying with emission standards, road-vehicles must be equipped with a supervising system (OBD) that monitors emission-related components and detects and indicate divergences from admissible pollutant limits. As of today, emission control systems are required for non-road mobile machinery, but not their monitoring by an OBD system. This paper starts with a short introduction to the classical OBD system. For more than three decades, OBD serves as an essential part of the environmental protection.

The Future of Short-Haul Transport Aircraft

1980-04-01
800755
Recently, major economic and regulatory changes have occurred which have initiated shifts in short-haul airline service patterns and aircraft technology requirements. Faced with rapidly escalating fuel costs, larger airlines have begun to move their jet transports to longer, more profitable routes. The short-haul routes left by the larger airlines are being serviced by the rapidly growing commuter airlines, largely using small turboprop powered aircraft. The transition to more efficient aircraft for short-haul will continue and, in the future, most short-haul operations will be performed by specialized propeller and rotor driven aircraft. This paper presents the results of some recent design studies of short-haul transport aircraft technology and provides illustrations of some potential future designs.

850137
This paper describes the current state of touch technology, the range of its applications, and its potential for use in the automotive industry. The implementation of touch input systems in automotive design is in its infancy, but the increasing use of sensor-intensive electronic control and diagnostic systems will necessitate streamlined presentation of diagnostic and safety information and the adaptation of the computer interface to accommodate a worldwide range of users, including users speaking different languages, unfamiliar with computers, and unsophisticated about automobiles. Touch input solves the problem of finding an easy, natural interface to a computer system. Current technology can meet high standards of performance, reliability and durability under harsh environmental conditions; touch systems are rapidly decreasing in cost; and new types of compact flat displays are under development.

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 electrical power system is the vital lifeline to most of the control systems on modern automobiles. The demands on the system are highly complex, and a detailed understanding of the system behaviour is necessary both to the process of systems integration and to the economic design of a specific control system or actuator. The following general trends are observed:- Increased use of electrically actuated systems Increased use of electronic control Increasing requirements for high integrity power supplies for safety critical systems Increased average electrical power consumption (heating, actuation, control systems) Increased electrical demand at engine idle combined with reducing idling speeds Increased interest in higher voltage systems. Electrical system problems are a major cause of road-side breakdowns.

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.

The Future of the FREE-PISTON ENGINE in Commercial Vehicles

1958-01-01
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.
