Audi Diesel Particulate Filters (DPFs) started being fitted to diesel models from around 2004 onwards, with many of its vehicles featuring the technology by 2008 as part of efforts to meet increasingly stringent emissions regulations in Europe. The European Union's Euro 4 emissions standard, which came into effect in 2005, required diesel vehicles to emit lower levels of particulate matter (PM) and nitrogen oxides (NOx).
DPFs work by trapping and collecting the soot particles produced by diesel engines, preventing them from being released into the atmosphere. The collected soot is then burned off periodically through a process called regeneration, which helps to keep the filter clean and maintain its effectiveness.
The company has continued to develop and refine its DPF technology over the years, with newer models featuring more advanced systems that can detect when regeneration is required and adjust their operations accordingly to minimize the impact on fuel consumption and performance.
DNW Automotive Ltd provides top-notch products that meet the strictest standards set by the manufacturers.
