Diesel Particulate Defuser (DPD)
Cutting-edge aftertreatment of emissions.
DPD is a regenerating after-treatment device that collects particulate matter emitted from the engine by means of a ceramic filter and efficiently burns PM using the precise fuel injection of the electronic control common-rail system and original ISUZU emission temperature control with emission throttles. ISUZU is meeting the new long-term emission control regulations and aggressively addressing development as one of the aftertreatment devices in conjunction with engines.
