Which risk significantly increases when injecting fuel directly into cylinder heads?

💡 Explanation

Elevated piston ring wear results from increased cylinder wall wash, because fuel impingement diminishes oil film lubricity. This `fuel dilution` effect encourages wear, therefore choosing hardened ring materials is crucial, rather than only addressing valve temperature or converter issues.
