Chery SQR472WF ACTECO 1.1L Naturally Aspirated Engine Horizontal Mini

Chery SQR472WF (ACTECO 1.1L Horizontal Naturally Aspirated Mini Engine)

I. Meaning of

Model Designation SQR: Original factory prefix for Chery engines 4: Inline four-cylinder layout 72: Cylinder bore of 72 mm W: Horizontal transverse layout (distinguished from vertical 472F used on QQ) F: Base 16-valve naturally aspirated variant of 1.1L displacement Classification of Horizontal Engines in the Same 472 Platform Series SQR472WF: 1083mL/1.1L horizontal engine, 55kW/75 hp, mainstream power unit for Karry minivans and mini trucks SQR472WB: Large-displacement 1251mL horizontal engine, 60kW/82 hp, fitted to high-spec Youyou / YouSheng models SQR472WD: Optimized 1251mL version with peak torque of 108 N·m, China National V emission standard SQR472WC: Early 1.1L horizontal engine for China National IV with low power output of 50kW

II. Basic Hardware Specifications

Displacement: 1083mL (1.1L) horizontal inline four-cylinder, water-cooled four-stroke Bore × Stroke: 72 mm × 66.5 mm Compression Ratio: 9.5:1 Valve Train: DOHC dual overhead camshaft, 4 valves per cylinder with total 16 valves; no VVT system Engine Construction: Cast iron cylinder block + aluminum cylinder head Timing System: Timing belt (mandatory full replacement at 60,000 km; snapped belt will bend engine valves) Engine Oil Capacity: Approx. 3.0 L Overall Layout: Horizontal design (fits compact front-wheel-drive engine bays of minivans) Emission Standard: Dual versions compliant with China National IV / National V Fuel Requirement: 92# or higher octane gasoline

III. Core Power Calibration Parameters (SQR472WF)

Rated Maximum Power: 55 kW / 75 hp @ 6000 rpm Peak Torque: 98 N·m @ 3500–4500 rpm Specific Power: 50.8 kW/L Fuel Consumption Reference Constant-speed fuel consumption at 40 km/h: 5.2 L/100km Combined urban fuel consumption under full load: 7.5–9 L/100km Steady suburban fuel consumption with no load: 6.0–6.8 L/100km

IV. Core Technical Highlights

Dedicated horizontal architecture that fits the narrow engine bays of Karry minivans and mini trucks with high space utilization DOHC 16-valve design delivers stronger high-RPM power output than 8-valve engines of equal displacement Multi-point port injection generates almost no intake carbon deposits, cutting maintenance costs for short-distance cargo transport High load-bearing capacity of cast iron cylinder block ensures durability and reliability under long-term heavy-load hauling conditions Simple mechanical structure with low-cost spare parts, serviceable at maintenance workshops nationwide

VII. Maintenance & Operation Precautions

Engine Oil Specification: 5W-30 mineral oil is acceptable; semi-synthetic oil recommended for long-term heavy-load use Timing Belt: Full kit replacement (belt + tensioner + idler pulley) required at 60,000 km; belt breakage will directly 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 Driving Characteristics: Torque is delivered at relatively high RPM with weak power output below 3000 rpm; higher RPM is required for climbing under full load. Engine is mainly designed for short-distance urban cargo transportation. Translation Standard Notes Automotive abbreviations: DOHC, VVT, MPI retain universal industry abbreviations Brand & Model Names: Karry is the official English name for Karry；model names Youya, Youyou, Youpai, Youjin remain transliterated as factory naming standards Emission Standards: China National IV / V adopt unified international automotive translation norms Units: kW, hp, N·m, rpm, L/100km, mm, mL follow international metric symbols
