Which outcome occurs when a diesel engine runs on fuel contaminated with water?

💡 Explanation

When water enters a diesel engine, the localized high temperature causes it to flash to steam which increases significantly in volume. This process, particularly as it exits the injector nozzles rapidly, causes erosion because of cavitation impacting on the nozzle surfaces repeatedly. Therefore injector tip erosion occurs, rather than cracking, ring failure, or corrosion, which require distinct chemical processes or longer exposure times.
