Which risk increases in a diesel engine when pilot injection volume deviates beyond the acceptable range in the ECU's calibration?

💡 Explanation

Uncontrolled cylinder pressure increases because pilot injection timing determines burn rate via premixing. Advanced or excessive pilot can cause too much fuel ready to burn at main injection—leading to knock, therefore causing pressure issues, rather than only emissions changes.
