Working principle of Cummins oil cooler: The function of the oil cooler is to cool the lubricating oil and keep the oil temperature within the normal working range. On high-power reinforced engines, due to the large heat load, oil coolers must be installed. When the engine is running, because the oil viscosity becomes thinner with the increase of temperature, the lubricating ability is reduced. Therefore, some engines are equipped with oil coolers to reduce the oil temperature and maintain a certain viscosity of lubricating oil. The oil cooler is arranged in the circulating oil circuit of the lubricating system
