Exhaust system & DPF 38 www.aftermarketonline.net OCTOBER 2024 Hit the bottle! Why DPF additives and toolkits are on the rise in workshops In recent years additives have really earned their place in the workshop. Especially when it comes to DPF cleaning. But for some time-served techs these additives are still off limits. Independent testing of the key ingredients has revealed that some DPF cleaning fluids have zero active ingredients despite the labels promising miraculous cleans. Others including DPF regeneration additives have such a high iron content that they risk irreparable thermal damage to the DPF from overuse. Does this mean the workshop technician must now add ‘forensic chemist’ to their list of responsibilities? Mike Schlup from Kalimex, the UK distributor of the JLM Lubricants’ range of ‘liquid tools’, wants to establish the key points of difference between a JLM product and the others. “Our unrelenting focus is on laying bare the active ingredients in every JLM product to show beyond doubt they really do live up to their claims. “In recent years, with motorists feeling the pinch at the pumps and at home, we’ve seen a real surge in workshop demand for the JLM Diesel DPF Cleaning Toolkit and the DPF Cleaning Fluid and Flush pack. For a time-pressed workshop, even the most badly blocked DPF can be cleaned on the vehicle.” Schlup said when it comes to cleaning a DPF that’s not reached the badly blocked stage, the technician needs a product that does not use iron as the catalyst. “In an ideal world the DPF would enter a regeneration cleaning phase where the temperature in the filter is artificially elevated to burn off the particles to reduce soot load. “For this to happen, the vehicle must be driven for a minimum distance at high revs on the motorway. But the regeneration cycle must complete.” However, many diesel vehicles are driven in environments where these higher temperatures are never attained. Add poor maintenance and a lack of regular servicing into the mix and the particle load in the DPF will continue to rise with no ‘burning off’, which can lead to complete filter blockage. With the DPF warning light on, the vehicle heads to the workshop, where it gets serious. Technician A chooses an iron-based product, a commonly used catalyst to assist particle burn by artificially increasing the temperature in the DPF. Despite reducing the filter’s particulate load, the elevated temperatures of up to 800°C risks causing irreversible damage to the DPF core. Technician B chooses the JLM Lubricants’ DPF Cleaner. With its cerium and platinum base, carbon deposits in the DPF burn off at a much lower temperature than the ironbased alternative — around 400°C. This helps protect and extend the life of the DPF core and produces less ash, extending DPF life.

Central to this is the exhaust gas recirculation (EGR) system, as it actively reduces the emissions that these engines naturally produce. However, as with every component, performance reduces over time, and when they or their associated parts need replacing is where Nissens Automotive can provide a premium quality aftermarket solution. The company continues to establish a solid footprint within the green automotive systems sector and the environmental impact of ICEs. Nissens’ range now comprises not only EGR valves, modules and coolers, but also intercoolers, turbochargers and a throttle body offering. Wholesalers supplying products from Nissens benefit from being able to source a comprehensive range of EGR parts solutions from a single supplier — under a brand that instils confidence with professional installers across Europe. Nissens EGR system components are premium aftermarket products that replicate the performance and fitment of the OE component to provide an extended, trouble-free function in the harsh conditions to which they are exposed, resulting from the frequent temperature and pressure fluctuations within the exhaust system. The entire Nissens engine efficiency and emissions programme encompasses 1,403 individual products, catering for more than 7,600 OE part numbers and serving the majority of the European PC/LCV parc.
