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