Which outcome results from the water hammer effect within high-pressure diesel fuel injection systems?

💡 Explanation

Injector nozzle erosion occurs because rapid valve closures induce high-pressure spikes propagating as a mechanical wave known as the water hammer effect; therefore, erosion occurs rather than improved fuel atomization, which requires consistent pressure.
