Mercedes Benz launched the standard diesel particulate filter of Euro IV
the particulate filter is applied to many Mercedes diesel cars. The innovative filter system does not need additives when running. The innovative filter system has the advantages of strong daily practicality, long service life and high efficiency
from October 2003, among its best-selling diesel cars, Mercedes Benz will take the lead in applying diesel particulate filters that meet Euro IV emission standards
the particulate filter system developed by Mercedes Benz does not need additives during operation, so the maximum pressure displayed on the display does not need to be replaced regularly, and it remains effective after a long driving distance
Professor J ü rgenhubbert, member of Daimler Chrysler Management Committee and President of Mercedes Automotive Group, said: "the particulate filter we first launched in the world can not only meet the Euro IV emission standard, but also almost completely eliminate particulate emissions, which will be applied to our diesel engines, which dominate the fleet business."
in Germany, the price of Mercedes Benz diesel particulate filter that meets the Euro IV emission standard is 580 euros (including VAT). When this vehicle is registered for the first time at the same time, consumers in Germany, the United Kingdom, Belgium, Sweden and the Netherlands will enjoy tax incentives, which will significantly reduce the additional costs, and even completely offset the additional costs
filter effect can be achieved without fuel additives
for Mercedes Benz, service life, daily practicality and fuel consumption are the key standards for the development of particulate filter system. Therefore, the filter system based on additives has basically built a new petroleum refining and chemical base with complete industrial chain; At the same time, the coupling development of coal chemical industry, salt chemical industry and biochemical industry cannot meet its requirements. According to the investigation and research, although this fuel additive improves the combustion of particles accumulated in the filter, the residual carbon ash in the filter channel cannot be recovered. After a long driving distance, these carbon ashes will block the filter, causing the exhaust back pressure to increase, thereby increasing fuel consumption. Richard Kirkby, product manager of biesterfeld petroplas engineering polymers, attributed the popularity of this material to its design flexibility, oxidized carbon emissions, and the continuous decline of engine performance
after using the Mercedes Benz particulate filter system, no additional maintenance measures are required in longer driving mileage. The filter can be restored by adjusting various control functions of the engine as required, such as fuel injection, intake throttle valve, exhaust gas recirculation, and boost pressure regulation. In this way, the exhaust temperature can be increased and the particles accumulated in the filter can be burned. The test results show that after driving a long distance, the residual carbon ash of the filter is reduced by 75% compared with the additive filter system. In addition, sulfur free fuel and special engine oil mean that these diesel particulate filters will have a longer service life
committed to reducing various emissions and fuel consumption
Mercedes Benz has successfully reduced particulate emissions by 87% since 1995 with its new particulate filter and new CDI engine (famous for common rail direct injection, four valve technology, exhaust gas recirculation and oxidation catalytic converter). Since 2005, the Euro IV standard has further reduced the gas emission limit by 84%Professor J ü rgenhubbert said: "reducing exhaust emissions and fuel consumption at the same time is one of our main goals. However, in order to give full play to the great potential of the future, we need not only cutting-edge engine technology, but also clean fuel and new fuels. For example, we recently launched 'biotrol' fuel for diesel engines, which is made of renewable raw materials and can be fully burned."
experience gained from the application of particulate filters since 1985
since the 1980s, Mercedes engineers have been committed to reducing particulate emissions. In 1985, Mercedes Benz took the lead in installing the particulate filter system in diesel cars sold to California, USA. During the implementation of the project, the experience gained by Mercedes laid an important foundation for the development of innovative filter technology
