1. Engine Application
Engine Application: Wuling Liuji LJ474QE2/Q3E2/QE9/QNE3 1.3L Inline 4-Cylinder Water-Cooled Gasoline Engine (1298cc)
Valvetrain: SOHC (Single Overhead Camshaft), 4 valves per cylinder (2 intake, 2 exhaust), 16 valves total, pent-roof combustion chamber
Material: High-pressure cast aluminum alloy (lightweight, excellent thermal conductivity)
Drive: Timing belt drive, non-VVT
Emissions: China III / China IV compliant
2. Structure and Core Components
Cylinder Head Body: One-piece aluminum casting with integrated coolant jacket, intake/exhaust ports, spark plug holes and camshaft bearing caps. SOHC layout, V-type valve arrangement, 4 valves per cylinder. Precision-machined sealing surface with reliable cylinder head gasket sealing. Precision-drilled oil/water passages and sensor mounting holes (camshaft position, water temperature).
Valve Drive System: Intake/Exhaust valves made of wear-resistant alloy with hardened seats, guides, dual springs, locks and seals. SOHC driven by timing belt, driving valves via rocker arms. Requires manual valve clearance adjustment (Cold: Intake 0.13-0.17mm, Exhaust 0.23-0.27mm). No hydraulic adjusters. Simple structure, low maintenance cost.
Included Components: Cylinder head body, camshaft, complete valve set (valves, seats, guides, springs, locks, seals), rocker arm assembly, valve cover with gasket, coolant/oil passage plugs, spark plug hole seals.
