Marketing tactics of the automotive after market business brokers

In fact, the SCR and EGR differences of the two routes as early as in 2010 has intensified. At that time, the Navistar adhere to the reason, the upgraded version of the EGR engine with a significant price advantage. Compared to engines using SCR technology to meet the standard of about $ 2,000 more expensive.

    But forced by the pressure of emissions in 2008, used to insist on the EGR line of Cummins to fight for big clients such as Daimler and Volvo, it has given up the SGR routes, the introduction of SCR technology. At this point, the Navy Secretary to reach EGR technology for the continental United States only to adhere.

    Guangxi Yuchai Engineering Research Institute, Dr. Numerical Simulated: "for a long time, the sulfur content in diesel will affect the route choice of emission control technology the most important factor. SCR catalytic converter exhaust after treatment system the most reliable system. "

However, the outcome of struggles over the direction of this technology, yet to be finalized. The day of the deadline, the reporter learned from the United States a heavy-duty engine business staff at the Navistar has already protested the verdict, and its engine is sent to EPA whether to re-test emissions standard, trying to restore the lawsuit.

    The EPA is drafting a ruling that Navistar still have emissions credits, and can continue to produce engines in the short term. Navistar said in a written statement: "Although this is a lawsuit filed by the EPD and the company competitors, but we do not agree with the Court's ruling and request for reconsideration."

    In addition, Navistar also said: "The company will continue to manufacture ship engines, customers will continue to be the supply of products with the EPA certified engines."

    U.S. lawsuit enough to make the Jianghuai senior attention, however, the real stimulus to the Amgen Chai Youguo IV criteria to be implemented next year.

    On January 10 this year, the State Ministry of Environmental Protection issued a notice requiring local immediate and strict implementation of the China IV standards for petrol cars, but due to the inadequate supply of standard diesel, diesel vehicles in the country the last time point of the standard implementation of the State IV 2013 7 months. This means that the heavy-duty truck diesel engine emission standards for the upgrade has had to face reality.

    "SCR is the best choice of the current State c heavy vehicle diesel engine." Numerical Simulated think.

    Domestic heavy-duty diesel engine choice one-sided situation. China National Heavy Duty Truck had to launch EGRDPF State c engine, also officially released the State IV technology auto dvd and car dvd player roadmap, that is, on the basis of the common rail, take SCR exhaust gas post-processing, in order to achieve the emission standards of the country c.

    Similarly, Weifang, the wood is also said that their country c emission control technologies routes will also use high-pressure common-rail SCR route.
