    • Abstract:
      The module estimates emission reductions for retrofitting diesel6 transit buses of a given model year with a specified retrofit technology. Emission reductions are estimated by calculating the reduction in running, start, and crankcase emissions from pre- to post-retrofit based on the pollutant and technology. This document is organized into three sections – User Guide, Tool Methodology, and Examples – to aid the user in understanding and interpreting results from the calculator. The User Guide gives direction for the user to properly input values into the tool and provides definitions of both user inputs and tool outputs. The Tool Methodology outlines the steps taken by the tool to calculate emission reductions, and includes all equations used within the tool. This Tool Methodology also includes a table of emission reductions rates for the retrofits provided in the tool. The Examples section aims to give some examples of how to properly input information into the tool
