ABSTRACT:
A particulate and exhaust emission control system for a vehicle (10) having a diesel engine (12). The control system has a particulate trap (24) connected to the exhaust manifold (22) of the diesel engine, an additive tank (30) for storing a fuel additive decomposed by the engine's combustion process to form a reducible metal oxide capable of depressing the ignition temperature of the carbon particulates collected by the particulate trap (24) and a metering mechanism (34) responsive to the adding of diesel fuel to the vehicle's fuel tank (28) to add a quantity of the fuel additive to the diesel fuel in the fuel tank (28) to maintain a predetermined ratio of the fuel additive to the diesel fuel in the tank. The metal oxide depressing the ignition temperature of the carbon particulates collected by the particulate trap (24) to a temperature obtained by the particulate trap during selected operating parameters of the diesel engine (12). The particulate trap (24) includes a honeycomb ceramic filter element (38) having inlet channels (44) for collecting the carbon particulate and exit channels (46) coated with a catalyst to oxidize carbon monoxide and unburned hydrocarbons in the exhaust.
