Chery SQR473F Vehicle Engine Assembly 1.3L 16 Valve Base Naturally Aspirated

Chery SQR473F (ACTECO 1.3L Naturally Aspirated Engine)

SQR473F Engine Compartment

I. Meaning of

Model Designation SQR: Factory prefix for all Chery engines 4: Inline four-cylinder layout 73: Cylinder bore of 73 mm F: Base naturally aspirated 16-valve variant (first-generation ACTECO jointly developed with AVL) Derivative Models on the Same Platform SQR473F: 1.3L 16-valve base naturally aspirated engine (main mass-production unit) SQR473H: Simplified 8-valve version of the same displacement

II. Basic Hardware Specifications

Displacement: 1297 mL (1.3 L), inline four-cylinder, water-cooled four-stroke Bore × Stroke: 73 mm × 77.5 mm Compression Ratio: 10.8:1 Valve Train: DOHC (Dual Overhead Camshaft), 4 valves per cylinder, total 16 valves Engine Construction: Cast iron cylinder block + aluminum cylinder head Timing System: Timing belt (requires periodic replacement, not timing chain) Engine Oil Capacity: Approx. 3.2 L Net Engine Weight: 134 kg Emission Standard: China National IV / Euro IV with OBD Fuel Requirement: 92# or higher octane gasoline

III. Core Power Calibration Parameters

Rated Maximum Power: 61 kW / 83 hp @ 6000 rpm Peak Torque: 114 N·m @ 3800–4500 rpm Specific Power: 47 kW/L Top Speed of Matching Vehicles: 156 km/h Fuel Consumption Reference Constant-speed fuel consumption at 60 km/h: 4.2 L/100km Actual combined urban fuel consumption: 5.8–7 L/100km

IV. Core Technical Highlights (1st-Generation ACTECO)

Jointly calibrated with Austria-based AVL; mature mechanical structure with outstanding durability for daily commuting Long intake manifold design moderately boosts low-speed torque, sufficient for city driving Multi-point port injection avoids carbon buildup issues common to direct injection engines and cuts maintenance costs DOHC 16-valve setup delivers sharper high-RPM response with more vigorous power output above 3000 rpm

V. Equipped Vehicles (A00/A0-Class Compact Cars, 2006–2014)

Chery Mini & Small Cars QQ6 1.3, Chery A1, Cowin 1, QQme, Riich M1, Riich X1, Chery Five Children series Matching Transmissions 5-speed manual QR512MH 5-speed AMT semi-automatic sequential transmission

VI. Maintenance & Operation Precautions

Engine Oil Grade: 5W-30 mineral oil or semi-synthetic oil are acceptable; full-synthetic oil is recommended for better performance if budget allows Timing Belt: Must be replaced every 60,000 km (including tensioner and idler pulley; broken belt will bend engine valves) Maintenance Interval: 5,000 km or 6 months (whichever comes first); initial maintenance at 3,000 km Consumable Replacement Cycle: Spark plugs replaced every 30,000 km; throttle valve cleaned every 20,000–30,000 km Operating Characteristics: Weak low-end torque; significant power loss under full load or with air conditioning on. Suitable for single-person short-distance daily trips Translation Standard Notes Professional abbreviations: DOHC, MPI, AMT, OBD, rpm retain universal automotive industry standards Model names: Cowin = Cowin,Riich = Riich,adopt Chery official English naming Emission standards: China National IV / Euro IV follow global unified translation norms Technical units: kW, hp, N·m, L/100km, mm, kg use international standard symbols
