A new platinum catalyst system has been developed at the Johnson Matthey Research Laboratories for the oxidation of hydrocarbons and carbon monoxide emitted by compression ignition internal combustion engines. The catalyst was evaluated during tests on a direct injection diesel engine using the 13-mode cycle devised by the California Air Resources Board, thereby assisting the design of catalyst systems to meet specific emission control targets in particular industrial applications. The new catalyst combined with retardation of injection timing can provide overall control of exhaust emissions, including the nitrogen oxides, from diesel engines.
