Which risk increases when over-pressurizing a gasoline direct injection (GDI) fuel system?

💡 Explanation

Erosion via 'cavitation' intensifies because increased pressure causes rapid vapourization and collapse of bubbles at the injector nozzle. The rapid injection causes localized pressure drops, leading to cavitation, therefore intensifying erosion by bubble creation, rather than a lessening of friction or improvement in efficiency.
