New Technology Meets Proposed EPA Diesel Truck Emission Rule.

BURBANK, Calif.--(BUSINESS WIRE)--Nov. 26, 1996--Micro-Pulse Controls, a developer of advanced diesel engine technology, has announced a new low-NOx (nitrogen oxide) engine-control system that has the potential to meet the most stringent emission regulations under consideration by the U.S. Environmental Protection Agency (EPA) and the Los Angeles-area's South Coast Air Quality Management District (SCAQMD). Unlike other low NOx technologies that increase production of particulates, the new Limited-Temperature Cycle combines a fast-burn technique with a reduced flame temperature to avoid formation of particulates from retarded injection timing. NOx reduction and particulate control are key components of the proposed EPA rule.

Based on an evolutionary improvement of the diesel engine cycle, the new Limited-Temperature Cycle engine-control operating system achieves NOx compliance below 1.0 gram/hp-hour, a level over three times cleaner than can be met by current diesel technology, in combination with particulate control below 0.1 gram/hp-hour. In addition, the Limited-Temperature Cycle enables a gain in fuel efficiency.

Micro-Pulse Controls expects to demonstrate the clean diesel technology in early 1997. Discussions have been initiated with diesel engine builders for cooperative development programs to apply the Limited-Temperature Cycle in heavy-duty diesel trucks. Micro-Pulse has licensed the technology from KT Partnership, owner of U.S. Patent 5,566,650, which issued Oct. 22, 1996.
