Which consequence results when fuel injectors operate at a lean setting?

💡 Explanation

High exhaust gas temperatures result because lean combustion reduces available fuel which raises oxygen concentration and causes rapid oxidation via increased local temperatures, therefore overheating various components rather than reducing knock, or CO emissions which a rich mixture causes.
