Ethanol data
Description
The ethanol data frame contains 88 sets of measurements for variables from an experiment in which ethanol was burned in a single cylinder automobile test engine.
This data set was part of the package SemiPar, which is no longer available at CRAN in compiled form. Copied to JOPS with slight modifications of the documentation.
Usage
data(ethanol)
Format
This data frame contains the following columns:
- 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.
