Cylinder head for Toyota 22REC

The cylinder head with part number 910170K serves as the upper closure for the engine block in the Toyota 22REC engine. It forms the combustion chambers where the air-fuel mixture ignites and contains the intake and exhaust ports, valve seats, and housings for the camshaft and fuel injectors. By maintaining the seal against the engine block, this component ensures the compression levels required for consistent engine operation and power output.

This cylinder head is compatible with the Toyota 22REC engine. It features integrated internal passages that facilitate the circulation of coolant to manage thermal loads during operation. The design accounts for the specific mounting requirements and fluid routing of the 22REC platform to ensure proper integration with the engine assembly.

In internal combustion engines, the cylinder head acts as the primary interface for gas exchange and thermal regulation. It houses the valvetrain and provides the structural framework for the combustion process, while its internal galleries allow for the transfer of heat away from the cylinder head surface to the cooling system.
