Background technique

The function of the lubricating oil cooler is to cool the lubricating oil and keep the oil temperature within the normal working range. On high-power enhanced engines, due to the large heat load, an oil cooler must be installed. When the engine is running, the lubricating ability is reduced because the viscosity of the lubricating oil becomes thinner as the temperature rises.
