发动机进水原因分析(国外英文资料) · analysis and elimination of oil failure in water tank , into the oil phenomenon: after water tank into the oil, after generally results in a cooling water in the cistern is a sticky milk white, make water tank of the cooling efficiency is reduced, the water temperature to rise. The normal use of diesel engines or other parts of the engine fail. ? analysis and exclusion: · 1, punch pad: when the cushion of the cylinder is damaged, the oil channel is connected to the channel, because the pressure of the engine oil is higher than the pressure of the cooling water and the oil enters the water channel before entering the water tank. The surface of the cooling water of the water tank is observed. When the water is down, the water will flow into the oil and into the oil bottom. · the cylinder liner cracks. Because of high fuel in cylinder pressure, oil and diesel oil under the action of high pressure, through the cylinder liner crack was squeeze into the cooling water, observe the surface of cooling water, air mass flow actuator is very severe. · trouble with engine oil cooler. When oil cooler assembly, manufacturing, cooling pipe itself exists crack or poor welding or because of winter, when stored in cooling water does not put clean cooling pipe caused by frost crack fault, such as the oil into the water. If you look at the water surface of the water tank, it is generally calm. All three types of failures can be identified by observing the changes of the water tank and cooling water. However, when observed, the water pump belt should be removed, the water pump stopped working, and the water in the tank is relatively stable. Instead of rushing to replace a piece of components. After the fault area is identified, repairs are made. · the analysis and exclusion of water failure in oil bottom case · phenomenon: the oil of the oil is the thick white congee, the lubricating efficiency is reduced, and it is very easy to cause the major failure of the cylinde
