Measurement of Exhaust from Burning Ethanol

Description

The ethanol data frame records 88 measurements (rows) for three variables (columns) NOx , C , and E from an experiment in which ethanol was burned in a single cylinder automobile test engine.
The gas data frame records 22 measurements of NOx and E from a similar experiment involving gasoline in place of ethanol.

Arguments

NOx the concentration of nitric oxide (NO) and nitrogen dioxide (NO2) in engine exhaust, normalized by the work done by the engine.
C the compression ratio of the engine.
E the equivalence ratio at which the engine was run---a measure of the richness of the air/ethanol mix.
