Abstract
Operation of a diesel engine with low particulate emissions is achieved. A diesel engine is equipped with a platinum-catalyzed particulate trap. The engine is operated with a blend of diesel fuel and a fuel-soluble cerium composition to reduce the balance point of the trap with reduced cerium content. Preferably, the fuel will also contain a fuel-soluble organo-platinum group metal compound, or an effective platinum group metal compound can be added to the exhaust or combustion air.
