Which consequence results when thermal stress compromises high-pressure diesel fuel injectors?

💡 Explanation

Compromised injectors cause incomplete combustion because nozzle deformation disrupts the fuel spray pattern during injection, leading to poor air-fuel mixing and elevated emissions; therefore, emissions increase rather than block cracking which relates to coolant issues.
