While examining a used fuel injection nozzle(s), one finds worn and enlarged orifices. What does this indicate about that cylinder's performance prior to nozzle replacement(s)?

Question

Accepted Answer

Reduced combustion efficiency, increased ignition delay, reduced atomization, and prolonged penetration.

Answer

Volume of atomization is increased, penetration is reduced, vaporization is increased, and efficiency is not affected.

Answer

Penetration is increased, air/fuel mixture is increased, and cylinder efficiency is not substantially affected.

Answer

Volume of fuel injected is increased, reduced injection pressure, decreased ignition delay.
