Why does the engine stall when it is short of oil?

If there is a shortage of oil, the engine will really stall. Reason: After oil shortage, the piston and bearing bush cannot be lubricated, and the temperature will rise sharply due to friction. The heat will lock up to a certain extent, so flameout, insufficient oil and high temperature boiling are the taboos of the engine, which seriously affect the life of the engine. Function of engine oil: Engine oil plays the role of lubrication. When the engine is working, the crankshaft is connected with the connecting rod through something commonly known as "tile", and the crankshaft is also placed on the engine cylinder block through the tile, as well as the piston ring and cylinder block. It's all friction, without oil lubrication, but dry friction, and the friction coefficient increases, causing serious wear of engine parts. Solution: You can only go to the 4s shop for engine maintenance; And be sure to change the oil regularly, add engine oil, clean up the stains inside the engine piston, and keep the engine running normally.
