Standby Generators for North Portal Electrical Loads (SCPB:N/A)

Description: The purpose and objective of this design analysis is to establish the best and most economical way to provide standby power generation required for the North Portal loads. This analysis calculates the size and number of the new standby generators that will supplement the already-specified four 500 kW diesel generator units (7007-GN-401, -402, -403, and -404).

Heavy Vehicle Propulsion Materials Program

Description: The objective of the Heavy Vehicle Propulsion Materials Program is to develop the enabling materials technology for the clean, high-efficiency diesel truck engines of the future. The development of cleaner, higher-efficiency diesel engines imposes greater mechanical, thermal, and tribological demands on materials of construction. Often the enabling technology for a new engine component is the material from which the part can be made. The Heavy Vehicle Propulsion Materials Program is a partnership between the Department of Energy (DOE), and the diesel engine companies in the United States, materials suppliers, national laboratories, and universities. A comprehensive research and development program has been developed to meet the enabling materials requirements for the diesel engines of the future. Advanced materials, including high-temperature metal alloys, intermetallics, cermets, ceramics, amorphous materials, metal- and ceramic-matrix composites, and coatings, are investigated for critical engine applications.

The Detroit Diesel DELTA Engine for Light Trucks and SUVs - Year 2000 Update

Description: Detroit Diesel Corporation (DDC) is developing the DELTA 4.0L V6 engine, specifically for the North American light truck market. This market poses unique requirements for a diesel engine, necessitating a clean sheet engine design. DELTA was developed from a clean sheet of paper, with the first engine firing just 228 days later. The process began with a Quality Function Deployment (QFD) analysis, which prioritized the development criteria. The development process integrated a co-located, fully cross-functional team. Suppliers were fully integrated and maintained on-site representation. The first demonstration vehicle moved under its own power 12 weeks after the first engine fired. It was demonstrated to the automotive press 18 days later. DELTA has repeatedly demonstrated its ability to disprove historical North American diesel perceptions and compete directly with gasoline engines. This paper outlines the Generation 0.0 development process and briefly defines the engine. A brief indication of the Generation 0.5 development status is given.

Diesel Engines Underground: [Part] 4. Effect on Composition of Exhaust Gas of Variables Influencing Fuel Injection

Description: Report issued by the Bureau of Mines over diesel engine operations. As stated in the introduction, "it is the purpose of this report to present such data and to reemphasize the importance of adequate maintenance for diesel engines used underground" (p. 2). This report includes tables, and illustrations.

NOx Adsorbers for Heavy Duty Truck Engines-Testing and Simulation

Description: This feasibility study of NOx adsorbers in heavy-duty diesel engines examined three configurations (dual-leg, single-leg and single-leg-bypass) in an integrated experimental setup, composed of a Detroit Diesel Class-8 truck engine, a catalyzed diesel particulate filter and the NOx absorber system. The setup also employed a reductant injection concept, sensors and advanced control strategies.

Exhaust Speciation Studies for Aftertreatment Technology Development

Description: Lean NOx reduction shown to be strongly affected by HC reductant composition. Possibility exists to tailor exhaust HC composition by manipulating HC post-injection process. Why is this relevant if lean NOx catalysis ''isn't going to work'' ? Lean NOx (esp. with post-injection of HC) offers unmatched ''passiveness'' NOx adsorber technology will require reductant - potentially introduced the same way
