<< DIESEL VERSIONS The following systems are used for reducing Diesel fuel engine emissions: oxidising catalytic converter, exhaust gas recirculation system (EGR) and particulate filter (DPF). DIESEL PARTICULATE FILTER (DPF) (Diesel Particulate Filter) The Diesel Particulate Filter is a mechanical filter, integral to the exhaust system, that physically traps carbon particles present in the exhaust gases of diesel engines. The diesel particulate filter is needed to eliminate almost all carbon particle emissions in compliance with current/future regulations and standards. During standard use of the vehicle, the Powertrain Control Module records a set of data (e.g.: travel time, type of route, temperatures, etc.) and it will then calculate how much particulate has been trapped by the filter.Since this filter physically traps particulate, it should be periodically regenerated (cleaned) at regular intervals by burning carbon particles. The regeneration procedure is controlled automatically by the Powertrain Control Module according to the filter conditions and vehicle usage conditions. During the regeneration there may be a limited increase in the engine idle speed, fan activation, a limited increase in fumes and high temperatures at the exhaust. These are not faults; they do not impair normal vehicle performance or damage the environment. >>
