COMPREHENSIVE SUMMARY

This exhaust thermal reactor program, which is being conducted within the Departments of Mechanical and Chemical Engineering at The University of Michigan over a three-year period has the following broad objectives:

• To quantify the effects that the various chemical and physical processes have on emission characteristics of exhaust thermal reactors installed on selected typical engines operating at various conditions on a dynamo-meter test stand.

• To obtain concentration measurements of pertinent chemical species and classes at the entrance to, within, and at the exit from thermal reactors, and from this data to determine gross chemical reaction rates.

• To obtain information which will be helpful in predicting the design of gasoline engine exhaust reactors.

To develop a computer model for thermal reactors.

The program has been divided into three phases of study. These are:

Phase I - Multi Cylinder and single cylinder engine mounted reactor experimental evaluation.

Phase II Computer model development.

Phase III- Special instrumentation development and measurements.

The current report details progress during the second year. Progress during the first year was detailed in  Annual Progress Report No.1.
