A -- HEAVY-DUTY DIESEL ENGINE TECHNOLOGY PROGRAM POC Andrew M. Hubbard, Contracting Officer, (216) 433-2809, MS 500-305 Internet E-Mail ahubbard@lerc.nasa.gov Dr. Mark Valco, Project Manager, (216) 433-3717, MS 86-6. NASA Lewis Research Center in conjunction with the Department of Energy is seeking sources for a proposed Heavy-duty Diesel Engine Technology (HDET) program procurement. The overall goal of the HDET program is to accelerate the ability of U.S. diesel engine manufacturers to meet proposed emission regulations while achieving improved efficiency in diesel engines with conventional and alternative fuel capability. This procurement is focused on heavy-duty diesel engine efficiency improvement and in-cylinder emission reduction. A major objective of this proposed procurement is validation Clean Diesel -- 50 Percent Efficient (CD50) engine technologies on a multi-cylinder test bed engine in 1999. Specific CD50 engine performance goals are 50% thermal efficiency and 2.0g/bhp*hr NOx and 0.5 g/bhp*hr particulate emissions levels which are equal to half of the 1998 EPA standards for heavy-duty diesel engines. The approach of this contract activity is to develop the technologies needed to achieve the proposed contract performance goals and validate the technologies on a multi-cylinder test bed engine. The test bed engine and subsystems shall be consistent with the typical performance needs of the heavy-duty diesel engine industry. The selected research and development technologies must be potential cost effective solutions with a viable technology transfer path into production engines, ultimately contributing to reduced petroleum demand and reduced emissions output. The date set for receipt of proposals is approximate. All interested parties may submit information for evaluation of their capabilities to the project manager prior to the closing date of this synopsis. All responsible sources may submit a proposal which whill be considered. Effective October 1, 1995, the Internet will be the only source of NASA Lewis Research Center MidRange synopses and soliciations.
