Why does the Boyue shake when starting cold?

[BraydenLynn]

The reasons for the Boyue shaking when starting cold include low temperature, inaccurate air-fuel mixture ratio, severe carbon deposits, and ignition coil failure. Taking the inaccurate air-fuel mixture ratio as an example: it exists in both open-loop and closed-loop control. If the car's computer makes a judgment error, its control over the air-fuel mixture and ignition timing through the actuators will be inaccurate, thereby reducing the car's power output and causing shaking. The Boyue is a model under Geely Auto, with body dimensions of 4519mm in length, 1831mm in width, and 1694mm in height, and a wheelbase of 2670mm. In terms of appearance, the Boyue's front face design follows Geely's family-style "water ripple" grille. Considering the sense of power of an SUV, the designer reduced the number of grids, making the overall look more concise and the edges more distinct.

I've also experienced shaking during cold starts with my Boyue, which is quite annoying. The most common causes include aging spark plugs or carbon buildup leading to poor ignition, resulting in unstable engine performance. Clogged fuel injectors can also cause poor fuel atomization during cold starts, affecting combustion efficiency. Severe engine carbon deposits are another culprit, especially in low winter temperatures. Additionally, a dirty throttle body can restrict air intake, making the startup process more jerky. Using old or improperly viscous engine oil that provides poor lubrication can worsen the shaking. Faulty sensors like oxygen sensors may also report incorrect data, misleading engine control. I recommend regular spark plug replacement, cleaning fuel injectors and throttle body every 20,000 km, using high-quality fuel additives to reduce carbon buildup, and timely oil changes for prevention. If the shaking is severe, visit a professional repair shop immediately to avoid affecting engine lifespan and driving safety. From my experience, maintaining good car care habits can save significant repair costs.

I've studied quite a few cases of the Boyue's cold start shaking, and there are many possible causes. The ignition system is the primary suspect: spark plugs may have reached the end of their lifespan or have thick carbon deposits, leading to inconsistent ignition; aging ignition coils could also cause unstable voltage. Fuel system issues shouldn't be overlooked either: clogged fuel injectors may result in inaccurate fuel injection during cold starts, or the use of low-quality gasoline can lead to gum deposits that cause blockages. Carbon buildup in the intake tract can restrict airflow and affect combustion balance. Severe engine carbon deposits, especially under low temperatures, can also lead to incomplete combustion. Sensor failures, such as the crankshaft position sensor, are common and can cause the ECU to misjudge engine speed. Simple troubleshooting steps: first try replacing the spark plugs; if the shaking persists, clean the throttle body and fuel injectors; check if the engine oil is fresh and at the proper level. Developing regular maintenance habits can help prevent these issues. I've noticed that if this problem isn't addressed, it can accelerate engine wear and even increase fuel consumption, so timely intervention is crucial.

My Boyue has been quite annoying with its shaking during cold starts, likely caused by a few minor issues. The spark plugs may have aged from prolonged use, or there could be excessive carbon buildup in the intake pipe, affecting smooth airflow during cold starts. If the fuel injectors are clogged with carbon deposits, poor fuel atomization can cause engine instability. Fuel system issues are also common, such as dirty gasoline or insufficient additives. Carbon buildup in the combustion chamber leads to incomplete combustion at low temperatures, resulting in shaking. Old or overly thin engine oil provides inadequate lubrication, causing stuttering during startup. It's recommended to promptly inspect and replace the spark plugs, regularly use fuel additives for cleaning, and maintain a clean fuel system. Additionally, ensure you're using quality fuel and avoid low-cost gas stations. This problem is easy to fix, so addressing it early will save you trouble.

I've experienced the cold start shaking issue with the Boyue several times and found it could potentially threaten driving safety. Common causes include worn-out or severely carbon-fouled spark plugs leading to ignition failure and engine shaking. Clogged fuel injectors can cause insufficient fuel supply during cold starts, affecting RPM stability. Excessive engine carbon buildup or a dirty throttle body obstructs air intake and leads to incomplete combustion. This results in significant vehicle shaking during startup, which could be dangerous if it leads to loss of control. I recommend immediately visiting a professional repair shop for inspection: replace spark plugs, clean the fuel system, and use diagnostic equipment to test sensors. For prevention, conduct regular maintenance checks every 5,000 kilometers using high-quality engine oil and gasoline. I've found that neglecting this issue can lead to engine damage or a sharp increase in fuel consumption - addressing it promptly is the safest approach.

Having driven for over a decade, cold start shaking in the Boyue is quite common, mostly due to carbon buildup issues. Old spark plugs with excessive carbon deposits cause uneven ignition, or clogged fuel injectors result in inaccurate fuel spraying. Severe engine carbon buildup leads to poor low-temperature combustion, making shaking likely. Fuel system problems like using poor-quality fuel with insufficient additives can also be the cause. Faulty sensors, such as a bad coolant temperature sensor, can mislead the control computer. Simple solutions: replace spark plugs, regularly add fuel system cleaners, and warm up the engine for half a minute before driving when cold. Change engine oil on time to maintain viscosity. This is a minor issue; regular maintenance can reduce its occurrence without affecting daily use.
