Diesel Particulate Filter Regeneration - All Others
The diesel particulate filter regeneration occurs during normal vehicle operation. The PCM may regenerate the diesel particulate filter at idle. During the diesel particulate filter regeneration, fuel is injected into the cylinder after the main combustion. The extra fuel increases the temperature of the exhaust gas and lightsoff the OC. The temperature of the exhaust gas increases to greater than 550°C (1, 022°F) at the OC and diesel particulate filter. At this temperature soot burns. Soot particulates that may have accumulated on the OC or in the diesel particulate filter are burned and the ash is trapped in the diesel particulate filter. The ash particulates that remain in the diesel particulate filter are mainly comprised of metallic compounds generated during combustion and from corrosion in the exhaust system.
