Cooling System
Cooling system prevents engines from being overheated to keep them at optimal
temperature levels.
The temperatures of combustion gas in cylinders range between 2,000~2,500
°, and much heat is conducted through cylinder walls, cylinder heads, pistons,
and valves.
The too high temperatures of these parts and their consequent bad combustion
weaken the relevant parts, cause mechanical troubles, shorten life span
of machines, and malfunction engines.
In addition, if overcooled, it will also cause problems such as excessive
energy consumption because low engine efficiency arises.
Thus, it is crucial to maintain the cooling system between 80 and 90 ° for
engines |
