Description

What is Engine parts Cylinder Head 202-03100-6428?

First of all, Cylinder Head 202-03100-6428 is an important component of the engine system. It is installed above the engine cylinder and serves the functions of sealing, fixing, supporting, cooling and lubrication. It is a large cast iron part, with a relatively complex structure and a high maintenance difficulty coefficient. Now, let’s introduce it in detail from the aspects of its function, structure, material and maintenance.

The main functions of the cylinder head 202-03100-6428 are as follows:

1. Sealing the cylinder: Installed above the cylinder block, it works together with the piston top and the cylinder wall to form a sealed space, preventing the high-temperature and high-pressure gases in the combustion chamber from leaking out, ensuring the normal operation of the engine.
2. Forming the combustion chamber: It is an important component of the combustion chamber, together with the piston top and the cylinder wall, forming the combustion chamber, providing space for the combustion of fuel. Its shape and structure have a significant impact on the combustion process and the performance of the engine.
3. Supporting the valve train: It provides support and installation positions for components such as the camshaft and rocker arm shaft of the valve train, ensuring the normal opening and closing of the valves and the smooth intake, compression, power generation and exhaust of gases, enabling the engine to complete the working cycles of intake, compression, power generation and exhaust.
4. Cooling and lubrication: It is internally cast with a water jacket, connected to the engine’s cooling system, using the circulation of coolant to remove the heat generated by the engine’s combustion, preventing the engine from overheating. Additionally, it provides channels for lubricating the valve train and other components.

The structure of SINOTRUCK cylinder head 202-03100-6428:

Whether it is a multi-cylinder engine or a single-cylinder engine, the cylinder head consists of the combustion chamber, valve seat, cooling water passage, and bolt holes.

In multi-cylinder engines, all the cylinders share one engine head. This structure is more compact, lighter in weight, has good sealing performance, which helps improve the overall performance and reliability of the engine. However, the manufacturing cost is relatively high. Once a certain part fails, the repair is more difficult.

The material of the cylinder head 202-03100-6428:

Cast iron: It has good wear resistance, corrosion resistance and compressive strength, and can withstand the high temperature, high pressure and mechanical stress generated by the heavy-duty engine during operation. The cost is relatively low, the processing technology is mature, but it is heavier and has poorer heat dissipation performance than aluminum alloy.

Aluminum alloy: It has the advantages of light weight and good heat conductivity, which can reduce the overall weight of the engine, improve fuel economy, and the good heat conductivity helps the engine dissipate heat, improving the performance and reliability of the engine.

Common faults of engine cylinder head 202-03100-6428:

1. Cracks and damage on the cylinder head 202-03100-6428. The main cause is that the engine operates under excessive load for a long time, resulting in the cylinder head bearing excessive thermal and mechanical stress, causing fatigue cracks. Secondly, insufficient coolant or malfunction of the cooling system leads to local overheating of the cylinder head, and it is prone to cracking when suddenly exposed to cold (such as after adding cold water when the coolant is low). 、
2. Cylinder head deformation. The main causes are uneven metal expansion under high temperature, or frequent alternation of hot and cold (such as frequent start/stop operations) leading to warping of the plane. Incorrect tightening sequence of bolts or insufficient/ excessive torque applied can cause uneven force distribution and deformation of the cylinder head.
3. Blockage and leakage. Failure to replace the coolant regularly can lead to blockage and leakage.

For engine cylinder head 202-03100-6428 in case of maintenance:

1. Regularly check if the coolant is sufficient, if the bolt torque is appropriate, and if there is any damage to the appearance. Through regular maintenance and correct usage, the service life of the SINOTRUK engine cylinder can be effectively prolonged, the occurrence rate of faults can be reduced, and the reliability and economy of the engine can be guaranteed.
2. Check for air leakage / water leakage: Regularly observe if there are any traces of coolant or engine oil leakage at the joint of the cylinder head and cylinder block, as well as at the water pipe interface (leakage of coolant may be manifested as a decrease in water level in the water tank; leakage of engine gas may cause a decrease in engine power and abnormal noise).
3. Inspection of water pump and thermostat: Ensure normal coolant circulation. If the water pump makes abnormal noise or the thermostat fails (resulting in excessively high or low water temperature), it must be replaced in time to avoid the engine head 202-03100-6428 from overheating and deforming due to poor heat dissipation.
