Meeting the California Medium-Duty truck emissions standards presents a significant challenge to automotive engineers due to the combination of sustained high temperature exhaust conditions, high flow rates and relatively high engine out emissions. A successful catalyst for an exhaust treatment system must be resistant to high temperature deactivation, maintain cold start performance and display high three-way conversion efficiencies under most operating conditions. This paper describes a catalyst technology and precious metal loading study targeting a California Medium-Duty truck LEV (MDV2) application. At the same time a direction is presented for optimizing toward the Federal Tier 1 standard through reduction of precious metal use. The paper identifies catalytic formulations for a twin substrate, 1.23 L medium-coupled converter. Two are used per vehicle, mounted 45 cm downstream of each manifold on a 5.7 L V8 engine.

The global economy, global competition, and the global customer are all factors driving change into the way companies manage their businesses. As the vision of a global economy becomes a reality, the utilization of standardization philosophies and techniques emerge as strategic priorities for companies desiring to gain and/or sustain global competitiveness. This paper begins with an exploration of the literature that identifies the lack of standardization and standards as a strategic competitive weakness of American industry. The exploration culminates in a series of conclusions that lead to the development of a new strategic approach to standardization and the challenges facing American industry. This new approach is called Strategic Standardization Management™. The paper then outlines the benefits of standardization and describes a generic transformation process that a company can use to implement Strategic Standardization Management™.
