Which outcome occurs when lean fuel mixtures combust in a turbocharger?

💡 Explanation

Increased turbine blade temperature occurs because lean fuel mixtures cause the flame temperature to increase due to a higher air/fuel ratio, leading to increased thermal load on the turbine via the mechanism of "stoichiometric imbalance." Thus, blade failure can result rather than improved engine efficiency.
