Which risk increases when a diesel engine's glow plugs fail?

💡 Explanation

Unburned fuel results from glow plug failure because inadequate cylinder temperatures prevent proper fuel vaporization, leading to incomplete combustion. The dominant mechanism is insufficient heat, therefore unburned fuel is the result, rather than other engine component failures.
