Chery SQRF4J20C Vehicle Engine Assembly 400T Full Aluminum With Inline Four

Product Specification

Chery SQRF4J20C (Kunpeng 2.0TGDI High-Power 400T Version)

I. Meaning of

Model Designation SQR: Original factory prefix for Chery engines F: 3rd-generation ACTECO TGDI direct injection engine series 4: Inline four-cylinder layout J: Turbocharged Gasoline Direct Injection 20: 2.0-liter displacement C: High-performance calibrated variant Distinction of Derivative Models in the Same Series SQRF4J20: Standard medium-power 390T (254 hp / 390 N·m, compatible with 92# gasoline) SQRF4J20C: High-power 400T (261 hp / 400 N·m, 95# gasoline recommended) SQRF4J20B: Special off-road calibration (exclusively for Jetour Traveler)

II. Basic Hardware Structure (Shares main hardware with SQRF4J20; only ECU and turbo wastegate calibration are reinforced)

Displacement: 1998 mL, 2.0L inline four-cylinder, DOHC 16-valve Engine Block Assembly: Full aluminum cylinder block + cylinder head with integrated exhaust manifold Valve Train: Dual VVT variable valve timing for intake and exhaust Fuel Supply System: 350 bar ultra-high-pressure gasoline direct injection with atomization particle size of 15 μm Turbocharger Assembly: Twin-scroll electronically controlled wastegate turbocharger with optimized wastegate logic; higher boost pressure at high RPM, turbo lag ≈ 0.2s Timing System: Silent timing chain (maintenance-free; only periodic full-synthetic oil changes required) Vibration Damping System: Scissor-type dual balance shafts + pendulum dual-mass flywheel; idle noise level of 61.8 dBA Combustion Cycle: Deep Miller cycle with a maximum thermal efficiency of 39.2% Engine Oil Capacity: Approximately 4 liters Emission Standard: China National VI b

III. Core Power Calibration Parameters (Exclusive to SQRF4J20C High-Power Version)

Maximum Power: 192 kW / 261 hp @ 5500 rpm Peak Torque: 400 N·m @ 1750–4000 rpm (same torque band as medium-power version, with a 10 N·m torque increase across the entire RPM range) Specific Power: 96 kW/L; Specific Torque: 200 N·m/L Mandatory Fuel Requirement: 95# or higher octane gasoline must be used. Long-term use of 92# gasoline will limit power output and may cause engine knock leading to component damage. Reference 0–100 km/h Acceleration Arrizo 8 PRO 400T (7DCT): 6.8 s Exeed Lingyun 400T (8AT): 6.58 s Tiggo 9 400T 2WD 8AT: Approximately 7.2 s WLTC Combined Fuel Consumption Sedans: Around 6.8 L/100km Midsize SUVs: 7.5–7.7 L/100km

IV. Core Differences vs. SQRF4J20 Medium-Power Version

Power Output: +7 hp maximum power, +10 N·m peak torque; stronger reserve power for mid-to-high speed acceleration Fuel Grade Standard: Medium-power unit supports 92# gasoline; high-power unit mandates 95# gasoline ECU Programming: Exclusive performance calibration for boost pressure, fuel injection strategy and ignition advance angle Cooling Matching: Vehicles equipped with the 400C engine feature a larger-capacity cooling system to sustain continuous high-load operation Transmission Matching: Prioritized pairing with Aisin 8AT / reinforced Fuzhen 7DCT for higher torque bearing capacity Market Positioning: Medium-power variant for daily family commuting; high-power variant focused on performance and flagship high-end trims

V. Core Technical Highlights

Twin-scroll Turbocharger: Separates high and low-speed exhaust gas flows; full torque output available at 1750 rpm for strong overtaking performance 350 bar High-Pressure Direct Injection: Improves air-fuel mixing, balances power and fuel economy, and reduces carbon buildup under low-speed driving Dual Balance Shafts + Dual-Mass Flywheel: Suppresses four-cylinder vibration, delivering top-tier idle and cruising quietness among peers Integrated High-Efficiency Thermal Management: Accelerates warm-up during cold starts and cuts excessive fuel consumption in winter Variable Displacement Oil Pump: Adjusts oil pressure on demand to reduce internal engine power loss Piston Cooling Jets + Low-Tension Piston Rings: Controls operating temperature under heavy loads and extends overall engine service life
