Exhaust gas analyser can measure different elements.enumerate six elements you may measure in the engine exhaust gas

Answer 1

An exhaust gas analyzer can measure various elements and compounds in the engine exhaust. Here are six common elements that may be measured:

1. **Carbon Dioxide (CO2)** - A primary product of combustion, indicating fuel efficiency and combustion completeness.
2. **Carbon Monoxide (CO)** - A toxic gas produced from incomplete combustion; levels can indicate fuel mixture issues.
3. **Nitrogen Oxides (NOx)** - A group of gases that include nitric oxide (NO) and nitrogen dioxide (NO2), contributing to smog and acid rain.
4. **Hydrocarbons (HC)** - Unburned or partially burned fuel that can contribute to air pollution and smog.
5. **Oxygen (O2)** - Measured to assess combustion efficiency and the air-fuel mixture; too much can indicate a lean mixture.
6. **Particulate Matter (PM)** - Solid or liquid particles suspended in exhaust that can affect air quality and human health.

These measurements are crucial for monitoring emissions and ensuring compliance with environmental regulations.
