Structure & Components
Cylinder Head Body
One-piece aluminum casting featuring integrated coolant jacket, intake and exhaust ports, combustion chamber, and spark plug/injector mounting points. Surface includes anti-slip diamond texture for optimal sealing and assembly precision.
Valve & Drive System
Wear-resistant alloy intake and exhaust valves guided by valve guides and seated on precision valve seats. Dual overhead camshafts (intake/exhaust) mounted on bearing caps, operating valves via hydraulic lash adjusters for maintenance-free operation.
Auxiliary Features
Includes cam phaser mounts for dual VVT (Variable Valve Timing), turbocharger-related piping interfaces, and precision-machined sealing surface for cylinder head gasket installation.
Technical Advantages
- Superior heat dissipation through aluminum alloy construction and integrated coolant jacket, ideal for turbocharged engine operation
- Optimized gas exchange efficiency with DOHC, 4-valve configuration, and dual VVT system for enhanced power output and fuel economy
- Engineered specifically for 1.8T turbo engines with compatibility for both multi-point injection and direct fuel injection systems
