Can the engine high-temperature warning not exceed 10 minutes?
1 Answers
Engine high-temperature warning should not exceed 10 minutes. Detailed explanation of why high-temperature warning should not exceed 10 minutes: Prolonged idling operation of the engine can lead to excessive carbon buildup. During idling, the engine operates under low-temperature combustion conditions, so it's advisable to avoid idling for more than ten minutes. Disadvantages of prolonged idling include: 1. During idling, the oil pump operates at low speed, resulting in minimal oil pressure - the lowest point for engine lubrication. This leads to poor lubrication for bearing shells and other moving parts, increasing wear risk. 2. Idling engines produce higher CO and HC emissions. 3. The water pump operates at reduced speed, compromising the cooling system's heat dissipation capability, forcing reliance on electric cooling fans.
