Which outcome occurs when timed fuel injection is mistimed during engine startup?

A)Hydrostatic lock within the cylinder
B)Increased catalyst light-off time
C)Reduced oil viscosity breakdown rate
D)Lower NOx pollutant formation rate

💡 Explanation

Hydrostatic lock occurs because excessive fuel accumulates in the cylinder due to erratic injection timing during cold start; the incompressible liquid prevents piston movement. Therefore, physical damage occurs, rather than improvements relating to emissions or oil properties.
