Which outcome accelerates in a Diesel engine when jacket coolant temperature severely drops during operation?

💡 Explanation

If the jacket coolant temperature suddenly drops, thermal shock may occur because rapid cooling causes uneven contraction leading to stress concentration exceeding material strength, therefore cylinder cracking emerges, rather than emissions reduction which is linked typically to higher temperatures.
