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)

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.
