Chery SQRE4G16 ACTECO 1.6L DOHC DVVT Naturally Aspirated Gasoline Engine

Full Introduction to Chery SQRE4G16 (Commonly Abbreviated as SQR4G16) 1.6L DVVT Engine

I. Basic Background The SQRE4G16 belongs to the second-generation ACTECO series, a 1.6L naturally aspirated gasoline engine jointly developed by Chery and Austria’s AVL. It entered mass production for vehicle installation around 2010 and serves as Chery’s classic mainstream naturally aspirated powertrain for family vehicles. Focused on economical daily commuting, robust durability and low maintenance costs, it is fitted to compact sedans and small SUVs. It complies with China National IV and National V emission standards successively. Without a turbocharger or direct injection system, it features a simple mechanical structure with an extremely low failure rate.

II. Core Technical Specifications

SQRE4G16 (commonly known as SQR4G16) 1.6L DVVTConstructionInline four-cylinder, water-cooled four-stroke, DOHC dual overhead camshaft, 4 valves per cylinder, dual DVVT intake & exhaust variable valve timing

Displacement 1598mL (1.6L) Bore × Stroke 81mm × 77.5mm Compression Ratio 11:1Valve Train Dual DVVT intake & exhaust variable valve timing + VIS variable-length intake manifold Fuel Supply ModeMPI multi-point port injection Maximum Power 93kW (126 hp) @ 6150rpm Peak Torque 160N·m @ 3900rpm Timing System Silent timing chain (no regular replacement required; inspect elongation at 150,000 km) Cylinder Block / Cylinder HeadFull aluminum alloy construction Engine Oil Capacity 4.2~4.5L; mineral, semi-synthetic and full-synthetic 5W-30/5W-40 oil are all factory-approvedFuel Grade 92# unleaded gasoline with wide fuel adaptability; compatible with LPG gas conversion Emission StandardEarly versions meet China National IV; facelift later versions meet China National VIII. Three Core Technical HighlightsDual DVVT Intake & Exhaust Variable Valve TimingIt adjusts the phase of both intake and exhaust camshafts simultaneously, boosting torque at low revs and improving air intake efficiency at high revs. Compared with older single VVT engines, it delivers lower fuel consumption and slighter idle vibration.VIS Variable-Length Intake ManifoldIt switches to long manifold passages at low speeds to enhance low-end torque, and short manifold passages at high speeds to increase intake airflow, optimizing mid-range acceleration performance.Silent Timing Chain + Full-Aluminum BodyIt abandons the timing belt used on the early SQR484F engine and requires no replacement throughout its service life. The full-aluminum block provides excellent heat dissipation and light weight, effectively avoiding overheating during urban traffic congestion.

Full Lineup of Equipped VehiclesSedansChery A3, Arrizo 7, Arrizo 3, Chery E5, Qoros 3 1.6LSUVs Tiggo 3 (main powertrain after mid-life facelift), Tiggo TTTransmission MatchingManual: 5-speed manual transmission (5MT)Automatic: CVT continuously variable transmission (Chery self-developed CVT)V. Power & Fuel Consumption PerformancePower CharacteristicsIt is a typical mid-to-high-rev naturally aspirated engine that only outputs peak torque at 3900rpm. Low-speed torque below 1500rpm is weak, resulting in mediocre power output under full load hill climbing or heavy-load overtaking. Power delivery above 2000rpm is linear and smooth, with sufficient reserve power for highway cruising.Manual-transmission variants offer agile driving and fuel efficiency, while CVT-equipped models feature milder acceleration and lower cruising RPM for better fuel economy at high speeds.Real-World Fuel Consumption Recorded by OwnersSedans with 5MT: Combined 6.2~7.0L/100km; urban 7.5~9L, highway 5.8~6.5LSUVs with CVT (Tiggo 3): Combined 7.2~8.2L/100km; urban 9~11L, highway 6.8~7.5LVI. Core Advantages of the EngineUltra-Simple Structure & Outstanding DurabilityFree of turbochargers and high-pressure direct injection systems, it suffers very few mechanical faults. Numerous examples have covered 300,000 kilometers without major overhauls, and it delivers exceptional stability after natural gas conversion for taxis and online car-hailing vehicles.Maintenance-Free

Timing ChainUnlike the SQR484F engine whose timing belt must be replaced every 60,000 km, it drastically cuts long-term maintenance costs.Broad Fuel CompatibilitySustained use of 92# gasoline will not trigger engine knocking, and it boasts high compatibility with LPG conversion, making it the top choice for commercial vehicles.Extremely Low Maintenance CostsA massive stock of affordable spare parts is widely available, and repairs can be completed at any local repair shop. Consumables such as oil filters, spark plugs and valve cover gaskets are low-priced.Stable Thermal ManagementThe full-aluminum body achieves balanced heat dissipation. With regular maintenance, faults like cylinder scoring due to overheating or blown head gaskets rarely occur.
