Why does a two-stroke motorcycle burn a mixture of gasoline and engine oil?

At present, the engine oil is put in a small oil tank, and the carburetor is supplied with oil at the right time through the motor oil pump. Oil required to ensure engine lubrication. However, it is not reliable to add engine oil directly to gasoline. The ratio of gasoline to engine oil is 30: 1, neither more nor less.
