The cylinder head is a fundamental part of any internal combustion engine, serving as the uppermost component of the engine block.
It seals the combustion chambers, houses the valves, and guides the airflow and fuel into the cylinders while expelling exhaust gases. The quality and design of the cylinder head have a direct impact on engine performance, emissions, and longevity.
Part Numbers and Compatibility:
2864016: This cylinder head is a critical component for Cummins engines, including the QSM11, ISM11, and M11. It is designed to fit these engines precisely, ensuring compatibility and optimal performance.
2864012: Similar to 2864016, this cylinder head is also compatible with the QSM11, ISM11, and M11 Cummins engines. It is manufactured to the same high standards, guaranteeing a reliable fit.
4952843: This cylinder head is designed specifically for Cummins QSM11 engines. It is engineered to meet the unique requirements and specifications of this engine model, ensuring efficient combustion and power generation.
4952444: Like 4952843, this cylinder head is tailored for Cummins QSM11 engines, providing a specialized solution for this particular engine variant.
Key Specifications and Features:
Material: The cylinder heads for Cummins CCEC QSM11, ISM11, and M11 engines are typically crafted from high-strength, heat-resistant materials such as cast iron or aluminum. These materials are chosen for their durability and ability to withstand the extreme temperatures and pressures within the engine.
Valve Configuration: These cylinder heads feature a complex network of passages and chambers to accommodate intake and exhaust valves. The precise design of these components ensures efficient airflow and exhaust gas removal, contributing to engine efficiency.
Sealing: Cylinder heads incorporate gaskets and seals to prevent the leakage of combustion gases and coolant.
Proper sealing is essential for maintaining engine performance and preventing overheating.
Bolt Holes: Cylinder heads have strategically positioned bolt holes that align with corresponding holes in the engine block. These holes allow for secure and precise attachment, ensuring the cylinder head remains firmly in place during engine operation.
Cooling Passages: To prevent overheating, the cylinder head contains a network of cooling passages through which coolant flows. These passages help regulate the temperature of the engine, preventing damage from excessive heat.
Precision Manufacturing: Cummins places a strong emphasis on precision manufacturing processes, including CNC machining and quality control, to ensure that cylinder heads meet strict tolerances and specifications. This results in consistent and reliable performance.
Compatibility: The specified part numbers (2864016, 2864012, 4952843, and 4952444) are designed to be direct replacements for the original cylinder heads in Cummins CCEC QSM11, ISM11, and M11 engines, ensuring easy installation and compatibility with existing engine components.
