← TechnologyWhich outcome occurs when rapid injection lags engine demand?
A)Reduced fuel economy and torque✓
B)Increased engine knock intensity
C)Optimized turbocharger impeller speeds
D)Complete stoichiometric combustion event
💡 Explanation
Reduced fuel economy and torque occur because insufficient in-cylinder air-fuel mixture exists during combustion, reducing energy release; this is due to mixture maldistribution rather than optimally leveraging fuel vaporization, therefore overall engine performance decreases.
