OCTOBER 2021 AFTERMARKET 47 www.aftermarketonline.net the problem by addressing the issues that contribute to the value’s premature failure. Recognising the problems associated with heat and lubrication, the Nissens team optimised gearbox design, significantly reduced tolerance and therefore friction, by applying specific PTFE, high- temperature resistant grease. Furthermore, the plastic material of the gear wheels in the two-stage gearbox has been upgraded. To avoid the known, severe malfunction of the valve caused by the engine load and vibrations, Nissens improved the valve's stem and lever arm fixings by applying a unique design of spiral pin. The DC motor's bearing system has also been improved to ensure its flawless operation and long service life, despite the vibrations and frequent temperature changes it has to deal LIQUI MOLY diesel particulate filter protection The Diesel Particulate Filter Protector from LIQUI MOLY is designed to keep the DPF clean, and enable it to last for longer. The service lives of diesel particulate filter are limited and can fall significantly below the manufacturer guidelines. One of the main causes of this is soot. LIQUI MOLY’s fuel additive keeps the filter clean and allows it to last longer, while also helping garages keep cars on the road. www.liqui-moly.com Ivor Searle: DPF cleaning Ivor Searle offers a fast turnaround off- vehicle DPF cleaning service for cars and vans. Using Flash Cleaning technology, Ivor Searle DPF removes all soot deposits, including PM10 particles, cerium oxide deposits and oil residues, from the DPF. Unlike chemical-based cleaning processes, which only remove soot, Flash Cleaning eliminates both soot and ash deposits. Alongside free collection and delivery, the service also includes an inspection report, plus a 12-month no-quibble unlimited mileage warranty. www.ivorsearle.co.uk with. The value of these improvements is proven by the redesigned valve undergoing a comprehensive validation procedure to secure its full functionality over its lifespan. Naturally, these tests include complete EGR valve operation and sensor feedback signal, under temperatures simulating conditions in the operational engine compartment, but also cooler performance for NOx emissions reduction, according to the Euro 5 norm, as well as the cooler bypass function for cold start. Finally, the valve undergoes a comprehensive corrosion test.” To view an installation guide, go to: https://support.nissens.com/material/egr-valve- installation-guide
