What is the function of the engine block?

1. The function of the engine block is the main body of the engine.

2. It connects each cylinder with the crankcase and is a supporting frame for installing pistons, crankshafts and other parts and accessories.

3. Cylinder block is one of the main parts of automobile engine.

4. The following is the cooling mode of the cylinder block: 1.

5. In order to ensure that the cylinder surface can work normally at high temperature, the cylinder and cylinder head must be cooled at any time.

6. There are two cooling methods: one is cooling with coolant (water cooling); The other is air cooling (air cooling); 2. Water cooling is widely used in automobile engines.

7. When the engine is cooled by water, there are cavities filled with coolant around the cylinder and in the cylinder head. These cavities are called water jackets.

8. The cylinder block and the water jacket on the cylinder head are connected with each other.

9.3. When the engine is air-cooled, many cooling fins are cast on the outer surfaces of the cylinder block and the cylinder head to increase the heat dissipation area and ensure sufficient heat dissipation.

10. Generally, the cylinder block and crankcase of an air-cooled engine are cast separately.
