Product Description:
A cylinder head is an important component of an internal combustion engine. It is typically a detachable part located at the top of the engine block, sealing the combustion chambers and housing various engine components.
The cylinder head sits above the cylinders and forms the top of the combustion chambers. It is usually made of cast iron or aluminum alloy to provide strength, heat resistance, and lightweight characteristics. The primary function of the cylinder head is to seal the combustion chambers, which contain the pistons, valves, and fuel-air mixture.
Key components and features found in a cylinder head include:
Combustion chambers: These are recessed areas within the cylinder head where the fuel-air mixture is ignited and combustion occurs. The shape and design of the combustion chambers play a significant role in determining factors such as fuel efficiency, power output, and emissions.
Cylinder ports: These are passages in the cylinder head that allow air and fuel to enter the combustion chambers while allowing exhaust gases to exit. Intake ports deliver the fuel-air mixture from the intake manifold to the combustion chambers, while exhaust ports facilitate the expulsion of exhaust gases.
Valves: The cylinder head houses intake and exhaust valves, which are responsible for controlling the flow of gases into and out of the combustion chambers. These valves open and close in a synchronized manner, allowing the intake of fresh air-fuel mixture and the expulsion of exhaust gases.
Valve seats and guides: The cylinder head contains valve seats, which are machined surfaces where the valves make contact and form a seal when closed. Valve guides are cylindrical passages that support and guide the valves during their movement.
Spark plugs: Spark plugs are threaded into the cylinder head and provide the electric spark necessary to ignite the air-fuel mixture in gasoline engines. They are positioned near the combustion chambers for efficient ignition.
Coolant passages: The cylinder head contains channels and passag
Product Application:
Apply for construction machinery industry excavator eninge assembly
Product Function:
The function of the cylinder head is to seal the cylinder, form a combustion space with the piston, and withstand the action of high-temperature and high-pressure gas. The cylinder head bears the mechanical load caused by gas force and tightening of cylinder bolts, while also bearing high thermal load due to contact with high-temperature gas. To ensure good sealing of the cylinder, the cylinder head must not be damaged or deformed. For this reason, the cylinder head should have sufficient strength and stiffness.
