High-performance cylinder head assembly designed for Changan BlueCore 1.6L engines, featuring advanced materials and precision engineering for optimal performance and reliability.
Compatible with China V / China VI emission regulations
Structure & Core Components
Cylinder Head Body
One-piece aluminum casting with integrated coolant jacket, intake/exhaust ports, combustion chamber, and spark plug/injector mounting holes
Optimized coolant flow design on the exhaust side to enhance heat dissipation under high-load conditions
Precision-machined sealing surface with reduced roughness, ensuring reliable sealing with the cylinder block and gasket
Valve Train System
Valves: Intake/exhaust valves made of wear-resistant alloy, matched with hardened valve seats and guides for extended service life
Camshafts: Dual overhead camshafts (intake/exhaust) mounted on bearing caps, driving valves via roller rocker arms and hydraulic lash adjusters (no manual clearance adjustment required)
Timing System: Silent timing chain drive (maintenance-free), compatible with VVT cam phasers for precise valve timing control
Included Components
Complete valve set (valves, springs, locks, oil seals, guides, seats)
Intake/exhaust camshafts with sprockets
Roller rocker arms and hydraulic lash adjusters
Valve cover with gasket
Timing chain tensioner and guides
Camshaft position sensor interface
Oil/water passage plugs and seals
Enhanced Features
Enhanced material for valve guides and seats, improving high-temperature resistance and wear resistance
Tighter machining tolerances for camshaft bearing bores and valve lifter bores, reducing NVH (Noise, Vibration, Harshness) and improving valve response
Optimized port geometry to enhance intake/exhaust efficiency, boosting power output and fuel economy
Standardized mounting interfaces, enabling direct replacement for older JL478QEE cylinder heads
Compatible Vehicle Models
Changan EADO (2014–2018 1.6L models)
Changan EADO DT
Changan Alsvin V7
Changan CS35 / CS35 PLUS (early 1.6L versions)
Changan CX20 (1.6L high-trim models)
Technical Notes
The new cylinder head assembly maintains full compatibility with the original cylinder block, bolt holes, and timing system. When replacing, verify compatibility with the VVT phaser, ECU version, exhaust manifold flange size, and spark plug heat range. Each assembly is 100% leak-tested and inspected for valve clearance and timing accuracy before delivery.
