Cylinder head


1, The cylinder head is installed on the cylinder block to seal the cylinder from above and form the combustion chamber. It is often in contact with high temperature and high pressure gas, so it bears a great thermal load and mechanical load. A cooling water jacket is made inside the cylinder head of a water-cooled engine, and the cooling water hole on the lower end of the cylinder head communicates with the cooling water hole of the cylinder block. Use circulating water to cool high temperature parts such as the combustion chamber.


2, The cylinder head is also equipped with intake and exhaust valve seats, valve guide holes for installing intake and exhaust valves, as well as intake and exhaust channels. The cylinder head of a gasoline engine is machined with holes for installing spark plugs, and the cylinder head of a diesel engine is machined with holes for installing fuel injectors. The cylinder head of the overhead camshaft engine is also machined with a camshaft bearing hole for installing the camshaft.


3, Cylinder heads are generally made of gray cast iron or alloy cast iron. Aluminum alloy has good thermal conductivity, which is beneficial to increase the compression ratio.


4, The cylinder head is an integral part of the combustion chamber. The shape of the combustion chamber has a great influence on the operation of the engine. Due to the different combustion methods of gasoline and diesel engines, the parts of the cylinder head that make up the combustion chamber are quite different. The combustion chamber of a gasoline engine is mainly in the cylinder head, while the combustion chamber of a diesel engine is mainly in the pit on the top of the piston.

Measures for cylinder head cracks


1. The cylinder head bolts should be tightened evenly and the oil supply time should be adjusted correctly.


2. Soft water should be added to the water tank, and the water should be changed as little as possible.


3. The engine should avoid long-term overloading.


4. When the engine is working and the water tank occasionally runs short of water, do not turn off the engine immediately, but slowly add water at low speed. Do not add cold water after the engine is hot. After stopping, wait until the water temperature is below 40°C before draining. It is not possible to add boiled water immediately during the cold winter season, but the water should be heated before adding boiled water.


5. Check whether the cooling water holes are unblocked during assembly. Regularly clean the cooling system with alkaline solution to remove scale and oil in time.
