Will a Three-Cylinder Car Become More Shaky Over Time? Generally, three-cylinder engines use balance shafts and specially designed engine mounts to suppress engine vibrations. As the engine mounts age with prolonged use, the vibrations can become more noticeable. Many engineers employ various techniques to mitigate the shaking of three-cylinder engines, such as adding balance shafts and using custom engine mounts. A three-cylinder engine consists of three cylinders arranged in a single block sharing a common crankshaft to output power, primarily converting chemical energy into mechanical energy. The main purpose of a three-cylinder engine is to provide power for traditional fuel-powered vehicles and new energy hybrid models.
Last year, I handled quite a few three-cylinder car repair cases and found that the shaking mainly comes from aging engine mounts. Three-cylinder engines inherently have greater vibrations, so manufacturers equip them with reinforced rubber mounts to absorb the shocks. Over time, the mounts crack and sag, causing noticeable vibrations in the steering wheel and seats. However, replacing the mounts is like putting on a pair of thick-soled shoes—it makes the ride smooth again. I personally recommend checking the chassis bushings every 60,000 kilometers. Replacing them with a set of polyurethane-reinforced mounts only costs a few hundred bucks. Here’s a lesser-known tip: using the right oil viscosity can reduce high-frequency vibrations by 20%, so older cars shouldn’t use low-viscosity oil indiscriminately.
