Loader Spare Parts QSC8.3 6C8.3 QSL Diesel Engine Cylinder Head 3945023

Diesel Engine Cylinder Head 3945023 Parameter:
1. The function of the cylinder head is to seal the cylinder, form a combustion space together with the piston, and withstand the effect of high temperature and high pressure gas. The cylinder head is subjected to mechanical loads caused by gas forces and tightening of cylinder bolts, as well as high thermal loads due to contact with high-temperature gas. In order to ensure a good sealing of the cylinder, the cylinder head can neither be damaged nor deformed. For this purpose, the cylinder head should have sufficient strength and rigidity.
2. Cylinder heads are generally made of high-quality gray cast iron or alloy cast iron, while gasoline engines for cars mostly use aluminum alloy cylinder heads. Aluminum alloy has good thermal conductivity, which is beneficial to improve the compression ratio of the engine. Secondly, it has excellent casting performance and is suitable for casting parts with complex structures. However, attention must be paid to the cooling of the aluminum alloy cylinder head, and the temperature of its bottom plane should be controlled below 300 °C. Otherwise, overheating of the bottom plane will cause plastic deformation and warping.
3. Application for Heavy duty truck, buses, engineering machinery, mining machinery, petroleum machinery, railway machinery, port machinery, stationary and mobile diesel generator set power stations, Marine propulsion unit and auxiliary power unit, pump power units and other power units, automobile industry power ships.

Types of Cylinder Heads

1. Flathead Cylinder Heads: These were the first type of cylinder heads. Flathead cylinder heads simply protect the cylinder block and have no moving parts. These cylinder heads do not allow for an efficient air flow, and thereby provide a poor engine performance.

2. Overhead Valve Cylinder Heads: These cylinders heads are superior to flathead cylinder heads. Overhead valve cylinder heads have the camshafts above them. These heads have their pushrods and valves connected to provide a smooth airflow.
3. Overhead Camshaft Cylinder Heads: These are the most advanced designs of cylinder heads. Overhead camshaft cylinder heads have the camshafts inside the cylinder head, eliminating the need of pushrods. This provides a better airflow, and in turn, increases the efficiency of the engine.
