______________ the exhaust gas is an indication of the incomplete combustion of fuel?
Correct answer: C. High % of CO in
- A. Low temperature of
- B. High temperature of
- C. High % of CO in
- D. High % of CO2 in
Explanation
Incomplete combustion does not oxidise all carbon to carbon dioxide, so the exhaust contains an elevated concentration of carbon monoxide. A high CO percentage is therefore a direct indication of incomplete combustion.
