Which mechanical failure arises when excessive charge-cooling occurs in gasoline direct injection (GDI) engines?

💡 Explanation

Increased piston ring blow-by occurs because charge cooling dilutes the oil film on the cylinder walls. This dilution reduces lubrication via oil control, therefore increasing piston ring leakage and pressure, rather than affecting the fuel injectors or exhaust directly.
