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.
