Product Description
New Cylinder Head Assembly for Changan 478QEE
High-performance cylinder head assembly designed for Changan BlueCore 1.6L engines, featuring advanced materials and precision engineering for optimal performance and reliability.
Technical Specifications
Engine Model JL478QEE (Changan BlueCore 1.6L naturally aspirated inline 4-cylinder gasoline engine)
Valvetrain DOHC (Dual Overhead Camshaft), 4 valves per cylinder (2 intake + 2 exhaust), with dual VVT (Variable Valve Timing) for intake and exhaust
Displacement & Compression 1598 cc, Compression Ratio: 10.4
Material High-pressure cast aluminum alloy (lightweight, excellent thermal conductivity)
Emission Standard 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.
