Using Gas Analyzer Readings For Engine Diagnosis

• General Background
• High Carbon Monoxide
• Normal CO
• Low CO
• High hydrocarbon
• (HC) Oxygen (O₂)
• High oxygen
• Low O₂
• High carbon dioxide (CO₂)
• Low carbon dioxide (CO₂)
• Oxides of Nitrogen
• High NOx Readings
• Low NOx
• Facts to Remember
• Chart One - Some of the kinds of problems that could result in abnormal gas readings.
• Chart Two - Some of the results possible when the AFR (air-fuel ratio) is sustained at conditions ranging from too lean to too rich.
