Engine exhaust fumes from burning ethanol
Description
Ethanol fuel was burned in a single-cylinder engine. For various settings of the engine compression and equivalence ratio, the emissions of nitrogen oxides were recorded.
Format
A data frame with 88 observations on the following 3 variables:
NOx
- Concentration of nitrogen oxides, NO and NO2, in micrograms per Joule
C
- Compression ratio of the engine
E
- Equivalence ratio - a measure of the richness of the air and ethanol fuel mixture.
