Title: Innovations by Woodrow Lewis, Jr.

Introduction

Woodrow Lewis, Jr. is an accomplished inventor based in Ypsilanti, MI (US). He has made significant contributions to the field of emission control systems, holding a total of 3 patents. His work focuses on improving the efficiency and effectiveness of diesel aftertreatment systems.

Latest Patents

One of his latest patents involves a method for accurately diagnosing deterioration in an emission control system for a lean burn internal combustion engine. This system includes an Active Lean NOx (ALNC) Catalyst and a mechanism for injecting a hydrocarbon-based reductant into the ALNC, thereby enhancing its NOx conversion efficiency. The method calculates a rate of change of exotherm across the ALNC and differentiates between the deterioration of the ALNC and the reductant injection system based on the magnitude and sign of the rate of change of the exotherm. Once the diagnosis is made, appropriate corrective measures are taken, such as adjusting or discontinuing the reductant injection amount.

Another patent focuses on a method and apparatus to limit the midbed temperature of a catalytic converter. An electronic engine controller determines the instantaneous temperature of a midbed point within the catalytic converter and compares it to a maximum midbed temperature range. If the temperature is within this range, the first air/fuel modulation variable is altered accordingly. This innovation aims to optimize engine performance while maintaining emission standards.
