Which phenomenon occurs when rapidly injecting high-pressure fuel into a diesel engine cylinder?

💡 Explanation

When high-pressure fuel is rapidly injected, fuel impingement occurs because the fuel jet size is too large or the spray angle is incorrect, spraying fuel onto the cylinder walls. That causes wall quenching, thus reducing localized combustion temperature, rather than polymerization, vapor lock or pre-ignition, which depend on fuel composition and combustion phasing.
