A diesel particulate filter (or DPF) is a device designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine. Wall-flow diesel particulate filters usually remove 85% or more of the soot, and under certain conditions can attain soot removal efficiencies approaching 100%. Some filters are single-use, intended for disposal and replacement once full of accumulated ash. Others are designed to burn off the accumulated particulate either passively through the use of a catalyst or by active means such as a fuel burner which heats the filter to soot combustion temperatures. This is accomplished by engine programming to run (when the filter is full) in a manner that elevates exhaust temperature or produces high amounts of NOx to oxidize the accumulated ash, or through other methods. This is known as "filter regeneration". Cleaning is also required as part of periodic maintenance, and it must be done carefully to avoid damaging the filter. Failure of fuel injectors or turbochargers resulting in contamination of the filter with raw diesel or engine oil can also necessitate cleaning.[1] The regeneration process occurs at road speeds higher than can generally be attained on city streets; vehicles driven exclusively at low speeds in urban traffic can require periodic trips at higher speeds to clean out the DPF.[2] If the driver ignores the warning light and waits too long to operate the vehicle above 40 miles per hour (64 km/h), the DPF may not regenerate properly, and continued operation past that point may spoil the DPF completely so it must be replaced.[3] Some newer diesel engines, namely those installed in combination vehicles, can also perform what is called a Parked Regeneration, where the engine increases RPM to around 1400 while parked, to increase the temperature of the exhaust.


SUMMARY

To complete the journey to ADR 80/03, Isuzu's N and F series models will:

• Continue to be fitted with a DPD.
• Use revised engine control module (ECM) software.
• Adopt improved exhaust gas recirculation (EGR) coolers to reduce NOx (nitrogen oxides) emissions.
• Feature higher injection pressure.
• Include a fuel cooler and primary fuel filter on NLR, NLS and NRR models.
• Additionally, Isuzu has introduced six new variants across the light-duty N-series and medium-duty F-series.
• In the medium-duty range, the FSR X-Long with a 6500 mm wheelbase, the FTR medium-long with a 6050 mm spread, and an FVR 1000 Auto model are the latest additions to the 62-strong F-series stable.
