← TechnologyWhich effect arises when gasoline's vapor pressure exceeds specifications?
A)Vapor lock in fuel lines✓
B)Increased engine knocking tendency
C)Catalytic converter deactivation occurs
D)Reduced exhaust particulate filtration
💡 Explanation
Higher vapor pressure leads to easier vaporization, causing bubbles in the fuel lines because the fuel pump can't maintain the required pressure against the vaporous fuel; therefore, vapor lock occurs, rather than improved combustion or catatlytic conversion, especially noticeable at elevated temperatures.
