What are the causes of engine vibration in the Boyue?
2 Answers
The causes of engine vibration in the Boyue are as follows: 1. Engine misfire. This mainly refers to one or more cylinders in the engine not functioning properly, typically manifested as: intermittent exhaust gas flow from the vehicle, severe shaking of the exhaust pipe, noticeable engine vibration, and sometimes accompanied by a sputtering sound. 2. Deterioration or loosening of engine mounts. Engine mounts are rubber blocks placed between the engine and the frame. Their function is to reduce vibration and absorb shocks during engine operation, as well as to secure the engine in place. Once these mounts deteriorate or become loose, the engine vibration will become significantly worse. 3. Carbon buildup issues, including carbon deposits in the cylinders, throttle body, spark plugs, and intake system. When there is excessive carbon buildup inside the engine, the vehicle's ignition energy, air intake efficiency, and air-fuel mixture ratio will be affected, leading to unstable power output and vibration during idling and acceleration.
My Boyue engine sometimes shakes, and I think it might be due to aging spark plugs. Worn-out spark plugs can cause uneven ignition, affecting the engine's smooth operation. Carbon buildup is also a common cause, especially with frequent short city trips, leading to incomplete combustion due to dirt accumulation in the fuel system. If the spark plugs check out fine, it's worth inspecting the ignition coils for damage or fuel system issues like clogged injectors. Damaged engine mounts can also amplify vibrations. It's advisable to start with the simplest fix—replacing the spark plugs—and regularly take the car on highways to clear carbon deposits. Don't delay too long to avoid further damage to the vehicle.
