SQRF4J16 Engine

SQRF4J16 1.6 T-GDI: Experiences, Issues, Fuel Consumption and Buying Used

Introduction and Applications

The engine with the code SQRF4J16 represents the third generation of Chery ACTECO engines, often developed in cooperation with Austrian giant AVL. This is not a cheap copy of old technologies, but a modern aluminum powerplant designed to compete with European and Japanese rivals in the compact crossover segment. It is best known for being installed in the Chery FX (Omoda 5 on some markets), where it brings a sporty character in a visually attractive package. Its main role is to offer above-average performance for the class (dominated by 150 hp engines) with acceptable running costs.

Reliability and Maintenance

This powerplant was designed to be robust, but like any modern direct-injection engine, it requires meticulous maintenance.

Timing drive: Chain or belt?

The SQRF4J16 engine uses a timing chain for valve timing. In theory this is a “lifetime” solution, but in practice, with modern turbo petrol engines, the chain should be inspected after 150,000 km. If you hear rattling on cold start that lasts more than a few seconds, it’s a sign that the chain has stretched or that the hydraulic tensioner is weakening.

Most common issues

Although this is a relatively new engine on the global market, a few things have stood out:

• Electronics and sensors: Occasional “phantom” issues with pressure or temperature sensors can appear, which may trigger the “Check Engine” light without any real mechanical fault.
• Carbon buildup: Due to direct injection, fuel does not wash over the intake valves. Over time, carbon deposits build up and can reduce power and increase fuel consumption. Periodic cleaning (decarbonization) or driving at higher revs on open roads is recommended.
• Coolant leaks: On earlier series, sporadic weaknesses were observed on the thermostat housing or hoses (clamps).

Service intervals and oil

The major service (replacement of timing chain, water pump, auxiliary belt and tensioners) is not strictly defined by mileage but by condition; however, an inspection is recommended around 120,000 – 150,000 km. Regular minor services are crucial.

Oil: The engine holds approximately 4.5 to 5 liters of oil (check the exact manual, as sumps may vary). Only fully synthetic oil of grade 5W-30 or 0W-20 is recommended (especially for models with a GPF filter). The factory interval is often 15,000 km, but it is strongly recommended to shorten it to 10,000 km due to the turbo and timing chain.

Oil consumption

This engine generally does not suffer from excessive oil consumption like some older European competitors. Consumption up to 0.5 liters per 10,000 km is considered perfectly acceptable. If it uses more than 1 liter between services, the turbocharger and piston rings should be checked.

Spark plugs (Petrol)

Since this is a turbocharged petrol engine with direct injection, the spark plugs are exposed to high thermal loads. Replacement is recommended every 40,000 to 60,000 km. Always use iridium or platinum spark plugs according to factory specifications.

Specific Parts and Costs

Dual-mass flywheel

Yes, this engine has a dual-mass flywheel, especially as it is paired with a DCT (dual-clutch) transmission. Its role is to reduce engine vibrations transmitted to the gearbox. It is not prone to early failure, but replacement is an expensive operation (cost depends on the market, but expect it to be “expensive”).

Injection system and turbo

The system uses high-pressure injectors (200+ bar). The injectors are generally reliable, but sensitive to poor fuel quality. A single injector can be expensive. The turbocharger (usually Honeywell/Garrett) is reliable with regular oil changes and proper cooldown after spirited driving. Expected lifespan is over 200,000 km with proper maintenance. The engine has a single turbocharger.

Emissions: GPF and EGR

To meet strict Euro standards, this engine in Europe almost certainly comes with a GPF filter (Gasoline Particulate Filter). It rarely clogs compared to a diesel DPF, because exhaust gas temperatures are higher on petrol engines. There is an EGR valve, which can get dirty from soot; symptoms include jerking at low revs.

AdBlue

This is a petrol engine, so it does not have an AdBlue system. That’s one less thing to worry about compared to modern diesels.

Fuel Consumption and Performance

City driving

Do not trust the factory figures of 7 liters. In real-world city traffic, the Chery FX with this engine consumes between 9.5 and 11.5 liters per 100 km. Vehicle weight and the automatic transmission take their toll.

Is the engine “lazy”?

Absolutely not. With 186 horsepower and, more importantly, 273 (or 290) Nm of torque available from low revs, this engine moves the body with no trouble at all. Acceleration is linear and overtaking is safe. The “Sport” mode further sharpens throttle response.

Highway

This is an excellent cruiser. Thanks to the 7-speed gearbox, at a speed of 130 km/h the engine spins at about 2,400 – 2,600 rpm (depending on gradient and load). At that point it is quiet, and fuel consumption is around 7.5 – 8.5 liters. Top speed is about 200 km/h, which shows there is a power reserve.

Additional Options and Modifications

LPG installation

Because of direct injection (injectors spray directly into the cylinder), LPG installation is complex and expensive. It requires a “Direct Injection” LPG system that still uses a small amount of petrol while running on gas (to cool the injectors), or a very expensive liquid-phase system. Given the high installation cost, it is only truly worthwhile if you drive more than about 25,000 km per year.

Chip tuning (Stage 1)

This engine has potential. A Stage 1 remap can safely raise power to around 205 – 215 hp and torque to over 300 Nm. However, be careful because of the gearbox – DCT transmissions have a torque limit they can handle. Excessive torque can shorten the lifespan of the clutch packs.

Transmission

Type of transmission

With the SQRF4J16 engine in the Chery FX model, you most commonly get a 7-speed DCT gearbox with dual wet clutches. The manufacturer is usually Getrag or Magna (designation 7DCT300 or a similar variant). Manual gearboxes with this power output are rarely, if ever, offered on the European market.

Issues and failures

The wet clutch setup is a much better solution than the dry type (which had a bad reputation). Still, possible issues include:

• Judder when moving off: Sometimes the gearbox software can get confused in stop-and-go traffic, resulting in slight judder. This is resolved with a software update.
• Delay when engaging R: Sometimes it needs a second or two to properly engage reverse.

Transmission maintenance

This is critical! The transmission oil must be changed every 60,000 km. Even if some claim it is “fill for life”, do not fall for it. Old oil causes mechatronic overheating and clutch slip. The clutch pack is a wear item and its replacement is expensive (very expensive, depending on the market).

Buying Used and Conclusion

Before buying a used example with this engine, make sure to check:

1. Cold start: Listen for chain rattling during the first 3–5 seconds.
2. Transmission: Test the car in heavy city traffic. Does it move off smoothly or does it jerk? Does it shift without thumps?
3. Service history: Was the oil changed on time? Neglect here is fatal for the turbo and timing chain.

Conclusion: The SQRF4J16 engine is a positive surprise from China. It offers class-leading performance, refined operation and modern technology. It is not the most economical at the pump, but it makes up for that with power and the equipment level of the cars it is installed in. It is ideal for drivers who want a modern SUV with enough power for safe overtaking and are willing to accept slightly higher fuel consumption in return.
