Abstract
A method of measuring a rate of change of carbon dioxide concentration in recirculated air of an engine, is disclosed. The method includes installing a conductive sample tube into an engine's pre-combustion/air-mixing chamber, and installing a carbon dioxide sensor, remote from the chamber, to measure relative concentrations of carbon dioxide. The method may also be used to measure nitrogen oxide exhaust gas levels.
