What Causes the Vibration During Acceleration at Around 50 km/h in the Boyue?

[IanLynn]

Possible causes of engine vibration include: A dirty air filter, broken high-voltage wires, worn-out spark plugs, abnormal water temperature, clogged fuel injectors, carbon deposits, oil sludge blockages, and other factors may lead to vibration. Here is a related introduction: Excessive Carbon Deposits: When there is excessive carbon buildup inside the engine, the gasoline sprayed by the cold-start injector can be largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts and making it difficult to start. Under such conditions, the engine can only start easily once the carbon deposits have absorbed enough gasoline to become saturated. After starting, the gasoline adsorbed on the carbon deposits is then drawn into the combustion chamber by the engine's vacuum suction, causing the air-fuel mixture to become too rich. This fluctuation between lean and rich mixtures leads to unstable idle speed and vibration after a cold start.

Oh, my Boyue also shook once when accelerating to around 50 km/h, which gave me a scare. I figured it might be a tire issue, like improper tire balance. After prolonged use, uneven tire wear can cause the car body to wobble during turns or acceleration. Also, if the wheel rim gets deformed from an impact, it can lead to imbalance. I went to the repair shop for a wheel balance, and the technician found it was a rear wheel issue—adjusted it and it was fine. Usually, it's important to avoid driving on rough roads too often and to regularly check tire wear and safety conditions. Remember, don’t delay fixing such shaking; handle it promptly to avoid damaging the suspension system and dangerous driving. If the problem persists, check if the drive shaft or engine mounts are loose.

Let me talk about the issue of shaking during acceleration. Common causes include unbalanced tires, where vibration becomes noticeable at certain speed ranges when the wheel alignment is off. If the suspension system is aging or loose, such as when the shock absorbers are damaged, the car body may shake when accelerating to around 50 mph. Alternatively, gaps in the drive shaft can also cause similar problems. I feel that in such cases, it's essential to first conduct a tire balance check at a reliable shop—don't just go for the cheapest option. Safe driving is the top priority; don't wait until an accident happens on the highway to regret it. During maintenance, pay extra attention to the wheels and suspension, and avoid stomping on the accelerator during normal driving to reduce component fatigue.

The car shakes when accelerating to around 50 km/h, which is quite annoying. In my case, it was a tire issue. Check if the tires are deflated or unevenly worn. Poor wheel balancing is also a common cause. I suggest stopping immediately to inspect it - addressing minor issues early prevents major problems. Safety first.

Acceleration shaking can range from minor to severe. I experienced this while driving the Boyue, with noticeable body wobbling around 50 km/h. Potential causes include loose or damaged suspension components, aging engine mounts transmitting vibrations, or chassis issues causing resonance. In such cases, immediately visit a workshop for diagnosis—don't wait for an incident. This becomes more dangerous at high speeds, making regular chassis maintenance crucial for prevention.

Speaking of vibration causes, unbalanced tires are often the culprit, but driveshaft play or worn drive axles can also induce vibrations during acceleration, especially around 50 mph. My Borui once had an out-of-round wheel hub issue which was resolved after timely repair. Occasionally, faulty spark plugs or fuel system problems may also cause shaking. A comprehensive inspection is recommended. Early intervention ensures safety.
