U.S. Opposed Piston Engine Challenges Traditional Diesel Engines

As an engine design company and technology provider, under the reporter's question, Johnson compared Achilles power to existing engine design companies. According to reports, four members of Aktis’s Technical Advisory Committee are researchers of the American Society of Automotive Engineers, two are members of the National Engineering Institute of the United States; the company has 52 engineers and scientists including 10 doctors, and the world First-rate equipment. The opposing engines of Fuji Heavy Industries of Japan and Porsche of Germany are all in the middle of the crank connecting rod mechanism, the piston and the cylinder head are at both ends, and the engine piston of Aktisth is formed in the cylinder barrel, eliminating the cylinder head mechanism.

Johnson introduced that the design of the opposed-piston two-stroke diesel engine was inspired by aeroengines that have been proven to be successful. The most important difference from traditional engines is in the combustion system. Its most advanced core technology is the patented cylinder design. In the design structure, the opposed-piston engine is simple and compact, the braking efficiency is expected to exceed 45%, and the nitrogen oxide emission is low. Since the use of parts is reduced and less raw materials are used, the engine's exhaust capacity can be made smaller and the entire engine can be made lighter; at the same time, however, traditional materials and manufacturing processes are used for manufacturing and manufacturing is inheritable. . A comparison of weight and cost shows that compared to a four-stroke engine with the same performance, the weight of the two-stroke opposed-piston engine is reduced by about 34% and the cost is reduced by about 12%.

Thanks to the design without cylinder head and valveless mechanism and the use of a breakthrough combustion system meter, the Arcettis opposed-piston engine reduces thermal energy and frictional losses compared to conventional four-stroke engines. There are obvious advantages. Test results show that this model can meet the requirements of US EPA10 and EU VI emission regulations; compared with the benchmark diesel engine, the fuel efficiency is increased by 15%, and compared with the corresponding gasoline engine, it is increased by about 55%. According to a test report provided by Acetes, the lowest fuel consumption rate of the Acettis opposed-piston engine is 195.3 grams compared with the benchmarked Ford 6.7 litre conventional four-stroke diesel engine. /kWh, compared with the benchmark engine's minimum fuel consumption rate of 239.9 g/kWh, a reduction of 18.6%.

The other advantage of the Arctice opposed-piston engine is that it does not require any fuel quality, because the model is very flexible in design and configuration. World-class competitiveness of the company's team According to a US study, the cost of improving fuel efficiency (reducing CO2 emissions) is extremely high if conventional engines are used. For example, to achieve a 10% improvement in fuel efficiency, the cost per vehicle is typically $16,740, which does not include the cost of about $10,000 per vehicle needed to reduce nitrogen oxides and particulate emissions.

Therefore, it can be said that any new type of engine that can fully improve the performance of the engine and have the ability to reduce costs, may become the future market choice. The experimental data proves that Achattis opposed two-stroke diesel engine can improve its performance at least by more than 10% compared with the traditional 6-cylinder diesel engine.

Johnson said that Achattis opposed-piston engine is suitable for all commercial vehicles and 90% of passenger cars, and can provide a variety of different engine specific structures and appearance size shapes according to the needs of host manufacturers and vehicle layout requirements. Since Achattis Power can record all important engine parameters and can detect battery conditions, an opposed-piston engine is also a model that meets the requirements of hybrid vehicles and can be adapted to future biomass applications.
