June 23, an interview with U.S. reporters in Beijing Akai Atlantis Power (achatesPower) President and CEO David? Johnson (DavidM.Johnson). He brought a reporter for the Chinese revolutionary engine design - opposed piston two-stroke diesel engines. Reporters learned that Fuji Heavy Industries and Germany's Porsche engines are on the home in the middle crank, piston and cylinder head at both ends, and Akai Tis the engine piston in the cylinder tube in the form of the home, eliminating the need for the cylinder head body.

    Core technology is the cylinder design

    Johnson introduced to the opposed piston two-stroke diesel engine design was inspired by the success has been proven to run aircraft engines, the main difference with the traditional combustion engine systems, the most advanced core technology is a patented cylinder design. In the design of the structure, the opposed piston engine simple and compact, braking efficiency is expected to more than 45% lower nitrogen oxide emissions. By reducing the use of parts, and use fewer raw materials, can make a smaller engine displacement, the engine is more portable; while still using traditional materials and production processes for manufacturing, with manufacturing inheritable. By weight and cost comparison shows that, with the performance compared to the same four-stroke engine, two-stroke opposed piston engine weight by about 34% cost reduction of about 12%.

    As a result of free-free cylinder head and valve train design, and uses a breakthrough combustion system design, Akai Aventis opposed piston engine to reduce the heat and friction losses, compared with the conventional four-stroke engine, bore / stroke ratio There are obvious advantages. Test results show that the kinds of models to meet U.S. and European ¢ö EPA10 emission regulations; compared with the baseline diesel engine, fuel efficiency increased by 15 percent, compared to the corresponding gasoline engine is increased by about 55%. Tis from Akai provide a test report that the subject has been very advanced with the Ford 6.7 liters compared to the traditional four-stroke diesel engines, Akai Aventis opposed piston engine fuel consumption rate of 195.3 grams minimum / kWh, while the standard engine than the minimum fuel consumption rate of 239.9 g / kWh, saving up to 18.6%.

    Akai Tis opposed piston engine Another advantage is that no requirements on fuel quality, this is because models in the design and configuration is very flexible.

    Company with world-class competitive team to a U.S. study data indicate that if the use of traditional forms of the engine, improve fuel efficiency (to reduce carbon dioxide emissions) is extremely costly. For example, to achieve 10% fuel efficiency improvement, renovation cost per vehicle is usually up to $ 16,740, not including to reduce emissions of nitrogen oxides and particulate matter need about $ 10,000 per vehicle cost. Therefore we can say that any full cost to improve engine performance and reduce the ability of the new engines are likely to become the future choice of the market. Experimental data to prove, Akai Aventis opposed two-stroke diesel engines in terms of performance than the traditional 6-cylinder diesel engine at least by 10% or more.

    Johnson said, Akai Aventis opposed piston engines for commercial vehicles and 90 percent of all passenger cars, and according to the arrangement of the host vehicle manufacturers needs and requirements, to provide a variety of different forms of engine size shape and appearance of the concrete structure. As Akai Tis power to record all the important engine parameters, and can detect the battery case, the opposed piston engine is consistent with the requirements of hybrid vehicle models, and may be suitable for future biomass energy applications.

    As a provider of engine design and technology company in the reporter's question, the Johnson Akai Tis the existing engine design with the power company to do a comparison. According to reports, Akai Tis Technical Advisory Committee has four members of the American Society of Automotive Engineers Fellow, two members of the U.S. National Academy of Engineering; owns, including 10 PhDs, including 52 engineers and scientists, and the World first-class equipment.
