If the best way to solve the future energy crisis is to use new energy vehicles represented by electric vehicles, then there is still a traditional internal combustion engine route when the electric vehicle is not universally popularized. Its representative work may be the EcoMotors OPOC engine. The two-stroke engine represented.
Of more than a dozen companies in the United States dedicated to the research and development of innovative engines and four to five companies focusing on the development of two-stroke engines, EcoMotors International (EcoMotors), which was established in early 2008, is one of the fastest growing companies. Since it invented a unique OPOC (Opposed Piston Opposed Cylinder) engine, it is the only engine structure in the world where the crankshaft is located in the center and two sets of opposed pistons are formed on both sides. A good solution to the problems of energy saving, heat dissipation and dynamic balance. Therefore, EcoMotors' OPOC engine may be the first to become a mass-produced new two-stroke engine.
A few days ago, at the headquarters of EcoMotors in Detroit, the Chinese media walked into this mysterious company and experienced its unique design ideas and business ideas.
Cleverly designed structure enables OPOC to exceed
Four-stroke engine capability
As the next-generation power propulsion system, EcoMotors' OPOC engine is a modular internal combustion engine product that is fully developed by the company and has a patented design. Its structural feature is that each module includes two opposing pistons and opposed cylinders, a crankshaft is connected between them, and two pistons in each cylinder are moved toward each other.
The cleverness of the OPOC engine is that it eliminates the cylinder head and valve control components of the conventional engine, providing an efficient, compact and simple core engine internal structure and fully self-balancing the engine. Its other big advantage is that it can inherit the traditional engine production mode in the processing technology and most of the parts, and can fully use the existing traditional fuels such as gasoline, diesel, and ethanol. On this basis, it can also flexibly add modules. The electric control clutches are combined with each other to increase the engine power, and a motor can be added to achieve a hybrid combination.
Due to the advantages of the four-stroke engine's emissions and the simple structure of the two-stroke engine, the OPOC engine only equates to half the volume and weight of a conventional engine, and has half the piston movement speed and very low piston lateral force. Friction losses can be reduced by half compared to conventional engines. Without the cylinder head structure, the heat transfer loss can be reduced by 30% to 40%; without the corresponding valve mechanism, energy loss of 5% can be saved. Coupled with the excellent scavenging capabilities of EcoMotors' unique electronically controlled turbocharger system, the OPOC engine's optimized combustion system significantly increases power density, and its specific power can exceed 1 hp/lb (2.2 hp/kg). ), can greatly reduce fuel consumption and reduce emissions; single module module fuel saving capacity of up to 15%, after multiple modules or join the motor, due to the use of cylinder deactivation technology, fuel saving rate of up to 45% or higher.
In addition, because the OPOC engine does not have a cylinder head and a valve mechanism, the design structure is simple, and 50% of the components are reduced compared to the conventional engine, so that its production efficiency and durability are greatly improved. And because all the internal forces of the OPOC engine can cancel each other out and have a balanced characteristic like a fully balanced multi-cylinder four-stroke engine, it has the characteristics of low noise and low vibration. It completely breaks the high fuel consumption of two-stroke engines. , high noise, poor discharge of the inherent impression.
Hope to own products like Apple Inc.
The same future
When it comes to EcoMotors, you have to mention its experienced management team and visionary investors.
Among the key members of the management team of EcoMotors, Professor Peter Hofbauer is founder, chairman and chief technology officer of EcoMotors. He led the development of the global powertrain at VW/Audi and led the development of Volkswagen/Audi's first modern diesel engine with the title of the best engine of the year. He has made many achievements in powertrain and booster systems. CEO Donald L. Runkle is vice president of engineering technology at General Motors, chief engineer at Chevrolet Engines, and president of Buick Powertrain. He also served as president of three operations departments at Delphi. Leading the development of several world-class engines including the world's top ten engines. O.John Coletti, President and Chief Operating Officer, is the global executive director of Ford Motor Company's high-performance cars. He led the development of a number of best-selling sports cars, including the 1994 Mustangs, and Ten Bests. engine. Under the leadership of this highly experienced and outstanding management team, EcoMotors has more than 150 patents and has developed more than 20 engines and more than 20 related vehicles have been put into production. As an investor in EcoMotors, Vinod Khosla has the title of "Global Investment in the Technology Field" and is the founder of Venture Capital. He has invested in more than 80 clean technology and information technology companies. It is a co-investor of the famous Sun Microsystems (Sun Mircosystems). The other major investor is Bill Gates, the famous Microsoft chairman. His evaluation of the EcoMotors OPOC engine is: "In the development of economical, low-emission vehicles, OPOC technology is an important cornerstone."
The OPOC engine is developed from high-powered diesel engine development. Its power can be from several kilowatts to several hundred kilowatts. The configuration combination is very flexible, and it is suitable for cars, trucks, agricultural vehicles, ships, stationary generators, off-road machinery, etc. Including any equipment that uses traditional gasoline or diesel as power. Currently, EcoMotors has signed a cooperation agreement with Navistar, a major truck manufacturer in North America, on joint development and commercial agreements, and also signed an engine development agreement with Zhongding Company in Anhui Province, China. In cooperation with other companies, consultations and cooperation intentions from companies including auto engine plants, commercial vehicle factories, generator sets, construction machinery, aviation, and military are being negotiated.
An office of Anhui Zhongding Company is located at the headquarters of EcoMotors. It is understood that Zhongding Company has a team of 40 to 50 people and is currently working on the application development of the OPOC engine project. At Hunan University in China, there is also a team of more than a dozen people led by Dr. Hai Gui of the original EcoMotors company engaged in data analysis, calculation, and other work outside the company EcoMotors.
According to Don Longkel, chief executive of EcoMotors, China's total automobile production will reach 30 million by 2030. If it is to jump from the current production of more than 18 million units to 30 million, it will generally need Added more than 40 engine factories. Don Runcker believes that if the 40 engine plants were constructed using the EcoMotors OPOC engine, the investment in the construction cost would be saved by one-third, and the carbon dioxide emissions and fuel consumption of new capacity products could be reduced by 20%~30. %, production and operation costs can also be reduced by a lot. He said with great confidence: "To build a new plant and build an OPOC plant, there is no point in building other new plants."
Integrated circuits replace diodes, mobile phones replace traditional landline phones, and MP3s replace bakelite records. From the point of view of the world's consumer electronics market, landmark milestone development has determined the pace of product replacement. Don Runkel believes that its OPOC engine has the ability to compete with Apple's iPhone, and far exceeds it in substance. "In China's huge and rapidly growing markets, OPOC engines can provide faster returns; and without the need for a lot of technology development funds or large-scale infrastructure investment, we can get huge benefits in terms of economy and reducing carbon emissions." Several executives of EcoMotors believe that with China’s largest and fastest-growing market, several electronic products such as Apple’s iPhone, iPad and iPod are similar in popularity around the world, and the OPOC engine was first developed by China. It is highly probable that it will rapidly expand into the global market.
