How is the three-cylinder engine of the Jiaji?

[DiFelicity]

This three-cylinder engine used in the Geely Jiaji is the same as the one in the Lynk & Co 02. Nowadays, with advancements in manufacturing processes and the application of technologies like balance shafts, even a three-cylinder engine performs excellently in vibration suppression. Generally, the more cylinders an engine has, the higher the vehicle's class, as cylinder count corresponds to displacement. Below is an introduction to the Geely Jiaji: 1. Powertrain Configuration: Geely's first MPV, positioned as a high-end premium family MPV. Strictly speaking, the Geely Jiaji has three powertrain configurations: 1.5T three-cylinder engine + 6-speed manual transmission (MT), 1.5T three-cylinder engine + electric motor + 7-speed dual-clutch transmission (DCT), and 1.8T four-cylinder engine + 6-speed automatic transmission (AT). 2. Reasons for Using a Three-Cylinder Engine: There is a global consensus on energy conservation and emission reduction. On one hand, the Jiaji adopts a three-cylinder engine to follow the mainstream trend. On the other hand, the manufacturing and maintenance costs of a three-cylinder engine are lower. A three-cylinder engine has one less set of intake and exhaust components and piston connecting rod structures compared to a four-cylinder, resulting in significant cost advantages. Additionally, a three-cylinder engine offers benefits such as reduced component weight and lower heat dissipation.

I've been driving the Jiaji three-cylinder model for half a year now, and the overall experience has been quite a pleasant surprise. There is indeed some slight vibration when starting up, and you can feel a tremor in the steering wheel, but it smooths out once you're on the move. The fuel consumption is exceptionally low, averaging around 6.8L for city commuting, and a full tank can last over 600 kilometers, saving a significant amount compared to my friend's four-cylinder. In terms of power, daily acceleration is sufficient, and shifting into S mode provides quick response for overtaking, though the noise amplifies a bit during hard acceleration, but closing the windows basically doesn't affect conversation. The engine uses a balance shaft and optimized suspension, making the ride quite comfortable on highways, and it's not tiring for long trips. The only thing is that it takes a few extra seconds to warm up the car during cold winter starts. Overall, this engine is economical and practical, perfect for commuters, and once you get used to it, you won't notice any issues at all.

From a technical perspective, the Jiaji's three-cylinder engine is ingeniously designed. It's lightweight with a compact structure, equipped with a dual-mass flywheel to control vibrations, resulting in decent noise suppression. However, there's a slight tremor under the seats at idle. The power delivery provides sufficient torque at low RPMs, making stop-and-go city driving smooth with fuel consumption maintained below 7L. That said, power output may slightly diminish during prolonged uphill climbs or high-load driving—don't expect it to perform too aggressively. Maintenance is straightforward, with routine servicing costing just a few hundred yuan. Remember to check the spark plugs every 30,000 km due to the higher working frequency of the three-cylinder engine, which accelerates wear. For oil, using full synthetic is recommended to extend engine life. Long-term reliability is solid—after two years and 40,000 km, it hasn't had any issues.

Our family's Jiaji three-cylinder engine focuses on practicality, offering spaciousness, low fuel consumption, and hassle-free operation. Engine vibration is barely noticeable, with only slight tremors at idle, but it runs smoothly and quietly when driving. Elderly family members have praised its quiet and comfortable ride, with good sound insulation. Turning up the AC adds stability. The average fuel consumption is 6.5L, saving us a lot on family trips. The engine is highly reliable—after a year and a half of use, it hasn’t needed repairs. Maintenance costs are low, and changing the oil and air filter is easy to do ourselves. Just avoid towing heavy loads, as the power is moderate, but it’s more than enough for daily use—safe and reliable. Once you get used to it, you’ll adapt completely.
