What Causes Jerking Sensation During Car Acceleration?
2 Answers
Jerking sensation during car acceleration is primarily caused by the engine and clutch. Specific details are as follows: 1. Lack of acceleration power: This issue is closely related to the engine, where ignition, intake, and fuel injectors collectively determine fuel combustion, which is the power source of the engine. Therefore, lack of acceleration power is naturally associated with these systems. 2. Jerking sensation during acceleration: If the car experiences both lack of acceleration power and jerking sensation, simple checks can be performed first, such as inspecting the oil level and whether maintenance has been neglected for components like the engine throttle, fuel injectors, spark plugs, and catalytic converter. Over time, these components tend to accumulate carbon deposits, which can affect the car's performance.
I was driving my old car on the highway when accelerating, and suddenly the car started jerking, feeling like it was being dragged by something, which was really scary. After taking it to the repair shop for inspection, they found that the spark plugs had aged and burned out, affecting the ignition system and causing uneven engine combustion. After replacing the new spark plugs, it ran smoothly again. Other possible causes include clogged fuel injectors, which disrupt the air-fuel mixture ratio due to poor fuel spray, or a dirty fuel filter with excessive carbon buildup, leading to insufficient fuel supply. Regular maintenance can prevent these issues. Generally, it's recommended to check the spark plugs and clean the fuel system every 20,000 kilometers. Don’t skimp on those small costs, as a breakdown on the highway can be dangerous and might even damage the transmission.
