Modern diesel vehicles by law include sophisticated emissions-control systems. These include a Diesel Particulate filter (DPF) which literally filters the amount of particulates passing into the atmosphere. It can reduce this amount by 80% - so does an extremely valuable job in lowering emissions... Until it gets clogged up by the very exhaust-borne emissions it's trying to control.

A level of particulate matter production is to be expected. Soot and ash, after all, are standard by-products of the combustion process. But what exacerbates the problem is poor combustion and oil evaporation which lead to excessive amounts of these deposits.

Annual preventative maintenance with BG Products' high quality chemistry will significantly reduce any deposit build-up, keep your engine running efficiently and produce less particulate matter, critically those components important to the performance and economy of the engine - Fuel Injectors, Piston Rings and various sensors. If fuel injectors are dirty, it will interfere with the efficiency and effectiveness of the fuel spray pattern. Deposits behind piston rings will restrict the ability of the rings to seal, causing a loss of compression and letting oil vapours blow-by and enter the exhaust stream. BG's twin-track fuel AND oil system cleaning regime combats all these issues.

Under normal conditions, the DPF is designed to use the very high temperatures created in the exhaust while the engine is under load to oxidise and evaporate the trapped particulate matter, thus cleaning (regenerating) itself. However, if this does not take place (perhaps because a high rev. journey did not happen for long enough) the particulate matter will continue to build up to a point that the DPF cannot regenerate itself - And this is also where BG's extensive R&D produced an effective solution.

The BG Diesel Intake and Emissions System Service uses innovative technology to restore the DPF, while simultaneously performing an intensive system clean. The service tool commands its own regeneration by controlling air intake flow and EGT (Exhaust Gas Temperature) to very precise levels. Once regen temperature is reached, BG's chemistry is used to clean soot right from intake all the way through to the DPF to be burned off and sent out the tailpipe.

Industry expert Frank Massey tested BG's Diesel Intake and Emissions System Service and achieved a 90% soot reduction. His Picoscope pre- and post-treatment readings can be seen on the right. This method means that BG don’t just clean the DPF filter but also treat the cause of the excessive soot too. Consequently the vehicle will have a cleaned DPF and also a better performing engine!
