← TechnologyWhich outcome occurs when fuel injector 'dribble' compromises stoichiometry?
A)Pre-ignition increases cylinder pressure
B)Thermal runaway in catalytic converter
C)Detonation erodes the piston crown✓
D)Volumetric engine efficiency increases
💡 Explanation
Detonation erodes the piston under high temperature, because uneven jets cause local, uncontrolled auto-ignition rather than controlled combustion: the *knock sensor* actuates timing retard. Therefore, power drops and erosion worsens, rather than efficient work, until injection improves.
