What Are the Hazards of a Car Cylinder Not Working
2 Answers
Specific hazards of a car cylinder not working are as follows: 1. Severe engine vibration: A car cylinder not working directly causes severe engine vibration at idle. 2. Abnormal noise from the exhaust pipe: Uneven exhaust flow from the pipe creates larger exhaust pulses, resulting in a popping sound. 3. Ignition coil damage: The ignition coil corresponding to the affected cylinder may have poor contact or excessive resistance, leading to ignition coil failure. 4. Reduced vehicle power: When a car engine's cylinder fails to work, it is called a misfire. Misfiring directly increases the engine's workload and prevents it from maintaining the original vehicle power level.
After repairing cars for so many years, I've often encountered vehicles with one cylinder not working, and the harm is really significant. Firstly, engine vibration increases dramatically, the steering wheel shakes severely, making driving uncomfortable, and over time, it may damage the engine mounts or exhaust system components. Power also drops noticeably, making it hard to climb hills and lacking strength during high-speed overtaking, which can lead to accidents due to insufficient acceleration in emergencies. Fuel consumption increases significantly because the other cylinders have to compensate, wasting gasoline money for nothing. Emissions also exceed standards, which is unfriendly to the environment. Worse, long-term neglect can cause chain reactions, such as ignition coil failure or catalytic converter blockage, doubling the repair costs. I recommend checking the spark plugs, fuel injectors, or fuel lines immediately if abnormal shaking or power loss is noticed, to prevent minor issues from becoming serious.
