Generally, those who engage in vehicle technology known in the industry, the automotive technology heavy-duty truck "Goldbach conjecture", and heavy-duty truck engine is the "Goldbach conjecture" on the "crown." Over the past now, all the world's premier luxury car should have advanced technology and high-end configuration, are also used in high-end or heavy-duty trucks have long been out of second-hand technology.

    Therefore, the concept of the development of new technologies of today's automotive industry and the latest trends, we see the present heavy truck technology and processes, like the removal of automobile technology crown, the measurable standard is heavy-duty truck engines. In recent years, China has also cloned a number of so-called "high-end heavy truck," but compared with the international truck giant predators, the gap is huge, especially in engine technology do not have a 20 -30 years of concentrated study and hard catch-up process is unable to achieve the ultimate goal of automotive power.

    Especially with the escalating emissions standards, and increasing the degree of the overload control, engine high-powered, large displacement of the trend is quite obvious. If the current Shanghai auto show last month, multinational commercial giants brought not only its many models, but also demonstrated its high-quality engines. The maximum displacement of domestic brands to 13L, EU standard power up to 480hp horsepower. The international commercial enterprises as the engine displacement is more than 15L, 16L, EU standard power in the 600hp horsepower or so. At present, these high-powered energy saving environmentally friendly engines in the country can not really produce, which is basically still in the stage of development.

    In recent years, due to lack of core technology engine, and then become the bottleneck of heavy truck technology. As we all know, the engine is the core component of heavy trucks, with engines to have the initiative in competition. Right now, China's heavy truck industry joint venture frequency is, take the market for technology, all heavy truck prices near the ocean wealthy, willing to be a "second wife" and "Little Three", is indeed true that the battle engine! China's heavy truck industry, the engine company to become the first point of the largest competitive race.

    Today I write with excerpts special car engine expert Mr. Chen Liang's article about the latest research and development in Europe and America heavy-duty truck engine giant paper to satisfy Tell me what you up to people:

    "The EU and other countries from December 31, 2012 ¢ö standards come into force in Europe. In order to seize the commanding heights of the market, foreign companies take the lead in the commercial vehicle particulate emissions of pollutants from the control to start, gradually introduced in line with EU standards ¢ö the engine, the whole car. "

    1, Daimler - Benz recently, Mercedes-Benz engine plant in Mannheim, Germany introduced the OM471 engine, called "blue-efficiency power."

    The release of this engine, so that the first launch of Mercedes-Benz meet the world standards of the European ¢ö truck engine manufacturers, OM471 Mercedes engine will be the future representatives in the engine area. OM471 for the inline 6-cylinder engine, the displacement of 12.8 liters, has 310 kW (421 hp) 375 kW (510 hp) power output range and 2100 to 2500 cows? Meters of torque. OM471 specifically designed to meet European emissions standards development, from development to release through the 5 years. The main techniques include SCR (Selective Catalytic Reduction of control), EGR (exhaust gas recirculation technology) and DPF (diesel particulate filter technology) and so on. The engine's core design is based on 2007 and 2010 in North America Daimler Japan using the new platform.

    OM471 Euro ¢ö engine fuel economy and now almost equal to Europe ¢õ engine, but the maintenance of mileage increase to 15 million km, the service life increased by 20%. OM471 United States and Japan to meet the latest emission standards, compared with other standards, these two criteria is more stringent emissions requirements. Mercedes-Benz released this engine, the foreign media prediction models will be the first to use Axor, Actros series may also be followed later this year the assembly, when the Actros if the current V-type engine replaced OM471, a new truck is expected to series. According to foreign media reports, the Mercedes-Benz engine has been carried out in Europe ¢ö over 600,000 km of testing, performance, reliability, technology maturity, have been verified. Mercedes-Benz said that in order to achieve the European ¢ö standards, including Mercedes-Benz, the major truck manufacturers will spend up to 8 billion euros, so price increases are inevitable.
