(PR NewsFoto) [PH] CHULA VISTA, CA USA 04/15/1999CHULA VISTA, Calif., April 15 -- BAT International (OTC Bulletin Board: BAAT) announced today that engines modified with its long-awaited Dolphin Pulse Charge technology are achieving breakthrough fuel efficiency. This patented technology will enable BAT to make final modifications to the first of many heavy polluting older Eastern European diesel bus engines.

"It is a truly simple yet revolutionary approach to improving the efficiency and emissions of internal combustion engines." The technology can be incorporated into both new and used engines when they are rebuilt. BAT's Dolphin Pulse Charge technology is an innovative redesign of internal combustion (IC) engines and the company has filed a patent application with the US Patent and Trademark Office. It is the same technology that enabled BAT's famous General Motors Geo Metro -- Dolphin Pulse Charged engine by BAT -- to achieve 81 miles per gallon at 55 mph during a 30 mile highway loop test last summer. It can easily be incorporated during engine overhauls on existing buses and trucks that are already on the road. "Not only will our technology significantly reduce air pollution," explains Joe LaStella, president and CEO of BAT International, "it will also improve fuel efficiency." In recent tests, the latest Pulse Charged engine design resulted in a 15-20% increase in fuel efficiency and a 15% increase in available horsepower. Fuel efficiency is especially important in Europe where fuel is more heavily taxed than in the U.S. In fact, the Pulse Charged engine even outperformed one of the most efficient diesel engines in the world that is made by Volkswagen. "The market potential is in the billions of dollars," says LaStella, "especially in Eastern Europe and former Soviet Union countries. There are more than 150,000 buses currently on the road in those countries whose engines are built by a manufacturer with whom BAT is currently participating in a Pulse Charge technology evaluation program." Dolphin Pulse Charge Technology Dolphin Pulse Charge technology significantly increases the breathing capacity (or volumetric efficiency) and decreases pumping losses of IC engines. The research required to achieve this breakthrough technology involved repeated sequential modifications of engine components in order to determine the overall effect of each modification on other components. "Over the past four years, more than 30 different engines have been modified and tested using Pulse Charge technology. Each modification involved component redesign, extensive machining, and rigorous dynamometer testing," said Holland. "In order to achieve optimum Pulse Charge benefits, new computer generated cam shaft profiles had to be developed. They are unlike anything now found in commercial engines. In addition, intake and exhaust manifolds, intake and exhaust ports, combustion chambers in the piston heads and fuel injection nozzles all had to be redesigned. However, once the engineering process is complete, the modifications can easily be integrated into new engines or during a scheduled engine overhauls." In tests at BAT's "skunk works" facilities in Costa Mesa, California, stock naturally aspirated (non-supercharged) Yanmar diesel engines modified with Pulse Charge technology achieved record setting efficiencies averaging .29 lbs. of fuel per horsepower hour (lbs./HP.hr). The Pulse Charged engines used for the tests incorporated no optimization devices. The .29 fuel efficiency is very significant when compared to a typical efficiency value of .38 lbs./HP.hr for a well designed naturally aspirated industrial engine and .34 lbs./HP.hr for a well designed supercharged engine. In addition, BAT's Pulse Charge engine efficiency value was better than the world's most efficient IC engine manufactured by Volkswagen (VW) which has a reported efficiency of .30 lbs./HP.hp. The dynamometer tests verify that a 15-20% improvement in fuel economy and a 15% improvement in horsepower can be achieved with Dolphin Pulse Charging. The technology can easily be incorporated in current engine production lines with limited tooling investments. This will allow marketing of the technology to both new engine companies and businesses rebuilding diesel engines. Applications in Eastern Europe BAT is now applying this engine efficiency technology to "clean up" the first bus engine from Eastern Europe. When all of the Pulse Charge modifications have been made to the engine, BAT will send it to a nationally recognized independent testing laboratory. The lab will perform fuel economy and emissions testing as part of contract data gathering requirements. Data from these tests is expected in two months. BAT anticipates even greater fuel economy and emission benefits from this heavy-duty engine test.
