Does Geely's Three-Cylinder Engine Shake Severely After Several Years?

With technological advancements, the shaking of Geely's three-cylinder engine after several years has become less noticeable. Here is an introduction to it: 1. Early three-cylinder engines might experience severe shaking after a few years of use. 2. Today's three-cylinder engine technology has matured. Although it still cannot be completely eliminated, the shaking has significantly decreased. By adopting the optimal single-cylinder combustion design, although the displacement is smaller, the power performance and fuel economy have improved considerably. Below is a description of the shaking issue with Geely's three-cylinder engine: (1) Shaking can be considered an inherent flaw of three-cylinder engines. Due to the odd number of cylinders, there is always one cylinder working alone, making it impossible to balance the inertial torque, thus causing shaking. This is especially severe at idle, and the more the car is driven, the more noticeable the shaking becomes. (2) Manufacturers use methods such as balance shafts to reduce shaking. Currently, there is no way to completely eliminate it, but the shaking issue has significantly decreased.

I've been repairing cars for over a decade and have encountered many Geely's three-cylinder models. Three-cylinder engines are inherently more prone to vibration than four-cylinder ones due to the missing cylinder causing operational imbalance. However, Geely has made significant efforts by adding balance shafts and dual-mass flywheels, which effectively control vibrations during the new car phase. After three to five years of use, some vehicles do exhibit more noticeable vibrations, especially during cold starts. This is primarily related to the aging of engine mounts, as the rubber hardens and deteriorates over time. I've personally tested several Geely three-cylinder cars with over 80,000 kilometers, and the steering wheel vibration at idle is about 30% more pronounced compared to new cars. But honestly, maintenance is crucial. With timely oil changes and prompt replacement of engine mounts, the vibration remains acceptable even after six or seven years of use—it won't shake to the point of being unbearable.

As a long-time owner of the Bin Yue, I've been driving it for over 4 years. When the car was new, I could barely feel any vibration. Now, during cold starts, it vibrates for about ten seconds until the RPM drops. During normal driving, there's not much noticeable vibration, except for a slight steering wheel tremor when waiting at red lights in D gear with the brake pressed. Once on the highway, I noticed severe body vibration, which turned out to be a tire balance issue—fixed after servicing. I feel the Geely three-cylinder's vibration increases slowly year by year, but it's nowhere near as exaggerated as online claims. Maintenance habits are key; I always use full synthetic oil during services. Now at 60,000 km, the vibration is still within acceptable limits, much steadier than my colleague's old Ford Focus three-cylinder.

From an automotive industry perspective, Geely's three-cylinder engine technology has become quite mature. They've adopted technologies like hydraulic mounts and balance shafts, making the initial vibration control significantly better than early three-cylinder engines. According to our collected data, vibration remains barely noticeable for the first three years, but there's a turning point after five years when engine mount wear leads to increased vibration. Interestingly, performance varies considerably across different models - Lynk & Co's three-cylinder engines demonstrate better stability than regular Geely models. A recent survey showed that among Emgrand GL three-cylinder owners with over 70,000 kilometers, about 30% reported noticeable vibration, though most found it within acceptable limits. Overall, well-maintained vehicles can last several years longer than those subjected to rough usage.

I drive my Geely ICON to work every day, covering over 50,000 kilometers in three years. The vibration issue depends on specific situations: it's most noticeable during cold starts but improves significantly after the engine warms up; the vibration increases when the air conditioning compressor is on at traffic lights; it's actually the smoothest at highway speeds. During one maintenance session, a mechanic taught me a little trick: filling up only half a tank of gas each time makes the car noticeably more stable. Now, I feel there's just a bit more minor vibration in the steering wheel compared to when it was new, but it doesn't affect driving at all. I've compared it with my friend's Buick Excelle three-cylinder, which vibrates much more noticeably—even the rearview mirror shakes at traffic lights. At least with the Geely, it doesn't interfere with listening to music, and placing a cup of water on the dashboard doesn't cause ripples.

Our after-sales service found that the common causes of vibration in three-cylinder cars are related to three major components: aging engine mounts, carbon buildup in the throttle body, and issues with tire dynamic balance. For vehicles with regular maintenance, the increase in vibration is very slow within five years. The most critical factor is the engine mounts; rubber components tend to harden after five or six years, so it's recommended to inspect them every two years. Secondly, using full synthetic oil can reduce carbon buildup, leading to smoother engine operation. One customer drove a three-cylinder Borui for seven years, consistently cleaning the throttle body during each maintenance, and the idle vibration is now controlled as well as a new car. To truly solve vibration issues, replacing with an improved set of hydraulic engine mounts is the most direct solution, potentially reducing vibration by about 50%.
