Diesel generator generatorroom ventilation is very important. Must ensure that adequate air circulation, in order to discharge the heat generated by the engine, generator and its accessories, smoke and exhaust, and supplement the air needed for combustion. Ventilation airflow should guarantee the room temperature below 10 degrees.

Water-cooled engine driving cycle pressure caused by the cooling water pump, gets the cooling fluid continuously circulation in the cylinder block and cylinder head pipe heat dissipation. Engine, cooling pump, radiator (or heat exchanger) constitute a pressure closed loop cooling system. The most common cooling components is driven online radiator and engine cooling fan. The alternative is online type liquid heat exchanger.
