Ideal air-to-fuel ratios are required to determine oxygen and fuel concentrations from the combustion cycle of automobile engines, not only for automotive manufacturers, but for high-performance racecars as well. These are not only crucial for optimal emissions breakdown through the catalytic converter, but from preventing excessive fuel consumption and possible detonation of the engine. One method of measuring air-to-fuel ratios is through zirconia-based lambda (air-to-fuel ratio) sensors. A standalone data-logging system that outputs real-time lambda, in respects to the engine's revolutions per minute (RPM), was developed.
