← TechnologyWhich condition follows asymmetrical piston crown temperatures in gasoline engines?
A)Increased pre-ignition knock risk✓
B)Improved exhaust gas recirculation
C)Reduced hydrocarbon engine emissions
D)Enhanced volatile fuel vaporization
💡 Explanation
Localized hot spots on the piston crown initiate auto-ignition before the spark because the increased temperatures surpass the fuel's auto-ignition threshold. Therefore, knock risk increases, rather than improved emission control or enhanced EGR, which relate to uniform combustion.
