It’s a case of basic chemistry – at high temperatures, AdBlue turns into ammonia, and it’s this process that breaks down the NOx. After it’s fed into the exhaust, it reacts with the NOx produced by the combustion process and breaks it down into harmless nitrogen and oxygen. When you or your mechanic send your DPF to us for a clean please ensure that the sensors aren’t removed as we will clean them as part of the service for no extra charge!ĪdBlue is a solution made up of urea and water that’s injected into the car’s exhaust system before NOx leaves your exhaust. Periodic maintenance is required to keep the DPF functioning correctly which in turn will keep the running costs of your Peugeot low, maintaining performance and reliability.Įxhaust Clean Australia are your experts in DPF cleaning with our revolutionary, market leading equipment ensuring clean emissions and trouble-free motoring. Over time the DPF can become blocked with a residue of ash from the soot trapped in the filter being burnt off in a process called regeneration. The soot emitted by diesel engines is particularly harmful to people who suffer with respiratory illnesses such as asthma, bronchitis and emphysema. If SCR isn’t properly maintained it can cause grief too! Diesel Particulate Filter (DPF)Īll Peugeot diesel powered vehicles have a DPF fitted to help in the reduction of harmful contaminants being expelled into the atmosphere.
Throw in DPF issues just for good measure if you are just pottering around the burbs at lower speeds as well. Peugeot’s line-up of vehicles suffer from EGR valve, cooler and intake soot issues like most diesel vehicles on the market.
It has been gradually added as standard equipment on diesel models sold as Euro 6 compliant. The Peugeot BlueHDi system has been implemented on select diesel-powered vehicles since 2013. This drops NOx emissions down to levels like gasoline powered engines while maintaining the diesel engine advantage of lower CO2 emissions and greater fuel efficiency.
The BlueHDi system is fitted to the majority of newer model Peugeot’s and has the selective catalytic reduction (SCR) positioned upstream of the particulate filter to eliminate up to 90 percent of the nitrogen oxides (NOx) released by the diesel engine.
