← ScienceWhich mechanism limits pressure rise due to energy equivalence in boosted combustion?
A)Shockwave-driven adiabatic compression
B)Incomplete fuel-air mixing
C)Flame kernel ionization instability
D)Turbulent deflagration-to-detonation transition✓
💡 Explanation
Detonation transition limits pressure because increased kinetic energy exceeds boundary dissipation, creating supersonic combustion waves, and rapidly elevates pressure and temperature. Therefore detonation, rather than slower deflagration and incomplete mixing, dictates the threshold where uncontrolled pressure spikes damage engine components.
