← TechnologyWhich consequence results when an intake valve sticks open in an engine?
A)Piston crown to valve contact✓
B)Excessive turbocharger shaft play
C)Fuel injector nozzle clogging
D)Crankshaft bearing oil starvation
💡 Explanation
Piston-valve contact becomes likely because the prolonged valve opening allows the piston to physically strike the valve during its upward stroke, causing damage to both, therefore impact occurs rather than normal combustion within tolerance.
