This data set gives the equivalence ratios and peak nitrogen oxide emissions in a study using pure ethanol as a spark-ignition engine fuel.

Usage

Format

This data frame consists of:

• NOThe peak nitrogen oxide emission levels.

• EquivalenceThe equivalence ratios for the engine at compression ratios from 7.5 to 18.
