ethanol.df: 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.

Usage

data(ethanol.df)

Arguments

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.
