Combat contamination

9 December 2013  

Strict emissions limits and the target of maximum efficiency have meant that diesel engines work very hard indeed and the resulting combustion residue can interfere with the delicate process. A large amount of combustion product is fed back into the chambers via the exhaust gas recirculation system which can create a vicious circle of incomplete combustion when deposits take hold in the system. This pattern can be fatal to parts such as diesel particulate filters (DPFs) and turbos, and a new range of products from JLM Lubricants have been designed to combat these issues. A Diesel ReGen Plus additive supports the regeneration process in DPFs, preventing the filter from becoming partially blocked. A DPF Cleaner is said to reduce the production of ash by 25% and the soot particles that do end up in the filter are burned off more thoroughly. It does this by lowering the temperature at which passive regeneration will take place. A DPF Cleaning Kit is to be used once a forced regen will no longer help. It works with the DPF in situ – first, the filter is cleaned with fluid and then flushed with DPF Flush. Finally, Diesel Extreme Clean is designed to detox older vehicles by cleaning components and protecting the engine.
