Which consequence results when valve timing fails in an engine?

💡 Explanation

Piston-valve collision risk increases because improper valve timing alters the Intake-Compression-Power-Exhaust (ICPE) cycle, causing asynchronous movement. Therefore, impact is likely rather than simultaneous valve opening and piston clearance, with correct timing.
