A total of four vehicles, two low excess air-oxidation catalyst systems and two three-way catalyst systems, were built to demonstrate the feasibility of low sulfate production automotive emission control technology. The general conclusions are summarized: (a) To successfully implement the low excess air concept the engine's fuel metering system must be capable of controlling the A/F ratio at the required 'slightly lean' value regardless of vehicle driving mode. (b) Secondly, the oxidation catalyst bed must light-off quickly from cold start conditions. (c) Third, the three-way catalyst must be maintained within its operating window by precise control of the engine at a stoichiometric A/F ratio.
