These particulates are removed during regeneration. The turbine spins as exhaust gas flows out of engine and over turbine blades and turns compressor wheel at other end of turbine shaft, pumping more air into intake system. The channels of the substrate filter are alternately blocked, so the exhaust gas and particulates are forced to pass through the filter medium and into the adjoining channels to exit the 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. During the diesel particulate filter regeneration, fuel is injected into the cylinder after the main combustion. Excessive heat can bulge or distort the converter or filter.
. On all models, the reduced emissions exhaust gas and any remaining particulates flow through the muffler and tailpipe into the atmosphere. As the exhaust gas passes through the filter medium, any particulates larger than the pores of the filter are removed from the flow of exhaust gas and trapped for diesel particulate filter regeneration. The converter body and diesel particulate filter should be inspected for distortion and other types of damage. The diesel particulate filter regeneration occurs during normal vehicle operation.Next
At this temperature soot burns and is reduced to ash. The exhaust gas and particulates are directed away from the engine through the exhaust manifold. Inspect for proper connection of electrical connectors and mechanical linkage. In the diesel particulate filter, the exhaust gas and particulates flow through the channels of substrate filter. Also inspect for missing or improperly installed converter heat shields. The reduced emissions exhaust gas and any remaining particulates flow through the muffler and tailpipe into the atmosphere.Next
