Fuel additive to protect DPFs

Published:  06 November, 2017

LIQUI MOLY has developed a fuel additive for diesel particulate filter (DPF) protection.

DPFs keep damaging soot out of the exhaust gases. Regeneration kicks in at set intervals once the exhaust gas reaches a certain temperature. Thus, the soot particles combust in the filter and it remains permeable. However, vehicles used mainly for short distances or in urban traffic often don't reach this temperature. This means  soot isn't completely combusted and it clogs up the filter more and more. The engine performance drops until finally the powertrain gives up completely. At this point, the only thing that will help is the replacement of the filter. Instead of taking place at 100,000 kilometres, this can occur as early as 20,000 kilometres.

 The new additive from LIQUI MOLY is added before fuelling every 2,000 kilometres. The contents of a 250 ml can is enough for 50 to 70 litres of diesel fuel and is suitable for all vehicles with a diesel particulate filter, as long as they don't have an electronically controlled additive tank system for filter regeneration, as is the case in Citroen and Peugeot vehicles.

    Schaeffler (UK) has teamed up with Liqui Moly to offer  Chain Protect, an additive which helps ensure the longevity of the timing chain and its associated components. The crucial element of any timing chain replacement is the ‘breaking-in’ phase, when the new chain beds itself in to the old engine system. Using Chain Protect can help ease wear during this phase by up to 20%. During the installation of an INA timing chain KIT, a technician should apply Chain Protect to the timing chain and associated components. This helps create a robust layer on all point of contact surfaces, resulting in smoother chain function and reduced friction.
