On Monday, August 4, 2008, Sonex Research, Inc. (“Sonex”) Chairman of the Board, Chief Executive Officer and President Dr. Andrew A. Pouring will make a presentation at the Diesel Engine-Efficiency and Emissions Research (DEER) Conference in Dearborn, Michigan.  The DEER Conference has been the U.S. Department of Energy's (DOE's) primary mechanism for the public exchange of state-of-the-art advanced combustion engine research and development (R&D).

DEER brings together professionals in the engine community including engineers, scientists, academics, State and Regional regulators, environmental researchers and nonprofit organizations. At DEER 2008, DOE will showcase its cooperatively funded R&D with its partners, national laboratories, the nation's automotive transportation industry, universities, and other national and international organizations. DEER fosters the exchange of information and best practices through presentations and posters from new and on-going engine R&D and networking with industry colleagues.

The DEER Conference, which runs through August 8, 2008, will feature technical sessions, presentations and discussions on subjects such as the following:

• Advanced Combustion Technologies (including In-Cylinder Emissions Reductions and Efficiency Improvements)
• High-Efficiency Engine Technologies (including Thermal Efficiency Improvement and Emissions Compliance; Development Challenges for Light-Duty Diesels)
• Emission Control Technologies (including NOx and PM Emission Control Technologies)

Dr. Pouring will give a Poster Presentation about the piston-based patented Sonex Combustion System (SCS) technology as it applies to four-stroke direct injected (DI) engines.  The SCS features chemical/turbulent enhancement of combustion for the reduction of emissions and improved fuel mileage, and the enablement of a new combustion process for normally aspirated and turbo-boosted or supercharged conditions.  The SCS for DI engines, based on patented piston technology containing micro-chambers with connecting vents, is applicable in two distinctive paths.  The first path, the Low Soot Diesel Design (LSDD), enables soot and oxides of nitrogen (NO_x) reductions in standard DI diesel engines at compression ratios greater than 16:1.

The second design path, called Sonex Controlled Auto Ignition (SCAI^TM), is for low to moderate compression ratio (<12.5:1) DI engines and enables precise control of auto-ignition, combustion and peak cylinder pressures with single phase controllable rates of heat release for a variety of fuels.  These attributes are the basis of the potential for lightweight engines.  The SCAI “sparkless” lean-burn combustion process in un-throttled, DI engines reduces emissions and significantly improves fuel economy due to the absence of a single flame front.  The SCAI has significant potential for commercial application in the automotive market for a new class of higher performance engines known as gasoline direct injection (GDI) engines to cost effectively improve fuel mileage 25% to 30% and address the exhaust emissions challenges inherent to GDI engines.

DEER Conference presentations and posters were selected by an open competition.  One-page abstract submissions were reviewed by a team of leading principal investigators in the field of engine research using the following criteria:

• Pertinence of the reported work to the objective of high efficiency clean combustion engine technologies
• How the proposed technology advances the state of the art of combustion engine efficiency and/or compliance with emissions regulations

The Poster Presentation session will take place immediately after the technical sessions end on Monday, August 4, 2008.  Dr. Pouring and other presenters will deliver a brief oral presentation before the attendees adjourn to a reception and the poster session itself, at which each presenter will have a designated poster exhibit.  Dr. Pouring will post explanatory materials and will be available to discuss the SCS.
