SAE J2601 Appendix I MC Formula-Based Flow Charts 19

APPENDIX I - SAE J2601 MC Formula-Based Flow Charts

I.1 Introduction

As per 9.7, this appendix details the flow charts for MC Formula-based fueling. These flow charts provide an explanation of the control logic for MC Formula-based fueling. These flow charts are to be used in conjunction with the subroutines detailed in Appendix J. Where appropriate, a reference to the applicable section and/or equation of Appendix J is called out in the flow charts.

An overview to the subroutines flow charts is as follows:
