Which outcome results when thermal stress causes a fuel injector nozzle crack, affecting combustion?

A)Increased exhaust valve temperature

B)Decreased manifold absolute pressure

C)Altered fuel-air stoichiometry✓

D)Elevated coolant system pressure

💡 Explanation

Fuel injector cracking affects combustion via altered fuel-air stoichiometry because the spray pattern degrades due to non-uniform fuel dispersion. Therefore, the ratio changes, rather than the pressure or component temperature fluctuating directly due to the cracked nozzle.
