     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.

_F_o_r_m_a_t:

     This data frame contains the following columns:

     _N_O_x 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.
