Transient Scuffing of Candidate Diesel Engine Materials at Temperatures up to 600<sup>o</sup>C

Description: This milestone report summarizes the general characteristics of scuffing damage to solid surfaces, then describes transient effects on scuffing observed during oscillating sliding wear tests of candidate material pairs for high-temperature diesel engine applications, like waste-gate bushings in exhaust gas recirculation (EGR) systems. It is shown that oxidation and the formation of wear particle layers influence the friction of such components. In the case of metallic materials in cylindrical c… more

Development and applications of GREET 2.7 -- The Transportation Vehicle-CycleModel.

Description: Argonne National Laboratory has developed a vehicle-cycle module for the Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREET) model. The fuel-cycle GREET model has been cited extensively and contains data on fuel cycles and vehicle operations. The vehicle-cycle model evaluates the energy and emission effects associated with vehicle material recovery and production, vehicle component fabrication, vehicle assembly, and vehicle disposal/recycling. With the addition of th… more

Livermore's 2004 R&D 100 Awards: Magnetically Levitated Train Takes Flight

Description: the 1960s, transportation industry planners have sought an energy-efficient design for a train that can glide through air at speeds up to 500 kilometers per hour. This type of train, called a magnetically levitated (maglev) train, is thought to be a viable solution to meet the nation's growing need for intercity and urban transportation networks. However, despite some promising developments, unresolved concerns with the operation and safety of maglev trains has prevented the transition from dem… more

Innovative Protocols for in SITU MTBE Degradation by Using Molecular Probes-An Enhanced Chemical-Bio Oxidation Technique

Description: In situ chemical oxidation (ISCO) is a common technology to cleanup petroleum hydrocarbon-contaminated soils and groundwater. Sodium percarbonate (SPC) is an oxidant which is activated by iron (Fe) to produce Fenton-like reactions. Western Research Institute, in conjunction with Regenesis and the U.S. Department of Energy, conducted a study that investigated the performance of a 'safe' oxidant, SPC, to cleanup groundwater and soils contaminated with petroleum hydrocarbons and associated contami… more

A refuelable zinc/air battery for fleet electric vehicle propulsion

Description: We report the development and on-vehicle testing of an engineering prototype zinc/air battery. The battery is refueled by periodic exchange of spent electrolyte for zinc particles entrained in fresh electrolyte. The technology is intended to provide a capability for nearly continuous vehicle operation, using the fleet s home base for 10 minute refuelings and zinc recycling instead of commercial infrastructure. In the battery, the zinc fuel particles are stored in hoppers, from which they are gr… more

DEVELOPMENT OF UREA-SCR FOR HEAVY-DUTY TRUCKS DEMONSTRATION UPDATE

Description: This study included engine cell and vehicle tests. The engine cell tests are aimed at determining NOX reduction using the US transient and OICA emissions test cycles. These cycles will be included in future US HD emissions standards. The vehicle tests will show urea-SCR system performance during real-world operation. These tests will prove that the technology can be successfully implemented and demonstrated over-the-road. The program objectives are to: (a) apply urea-SCR to a US HD diesel engin… more

HCCI Combustion Fundamentals: In-Cylinder Diagnostics and Kinetic-Rate Computations

Description: Substantial progress has been made in reducing emissions and improving the performance of Diesel engines. Appears to be a lower limit for engine-out NOX of about 1 g/hp-hr. Serious difficulty in meeting Tier II or newly proposed H-D standards. Homogeneous charge compression ignition (HCCI) is an alternative IC engine combustion process that has the potential to: Provide diesel-like or higher efficiencies. Very low engine-out NOX due to low combustion temperatures. Very low particulate (PM) emis… more
