← TechnologyWhich risk increases when rapid cylinder preheating promotes early fuel vaporization?
A)Increased octane requirement shift✓
B)Enhanced volumetric combustion efficiency
C)Consistent fuel-air mixture quality
D)Reduced risk of engine knock
💡 Explanation
Engine Knock increases because pre-ignition occurs when highly vaporized fuel auto-ignites prematurely due to higher cylinder temperatures. Therefore, octane demand rises rather than resulting in stable combustion since early vaporization lowers effective octane rating under increased temperatures.
