What are the reasons for jerking during car driving?
2 Answers
Reasons for jerking during car driving: 1. If the engine's air intake decreases, ignition weakens, or fuel injection reduces, the power will be insufficient, leading to a jerking sensation; 2. Irregular wear of the clutch three-piece set, namely the flywheel, clutch disc, and pressure plate, causes one or several components to wobble. Theoretically, except for CVT transmissions, all other transmissions may experience jerking. CVT transmissions, also known as continuously variable transmissions, do not have the concept of gears, so naturally, CVTs do not have gear-shifting jerking. It is also normal for automatic transmission cars to have a jerking sensation during gear shifts, but the intensity varies from car to car.
As a seasoned driver with over a decade of experience, I often encounter jerking issues while driving, which are usually caused by ignition system problems. For instance, when spark plugs age and their resistance increases, unstable ignition occurs, making the engine jerk during acceleration. Fuel system issues can also be to blame, such as carbon buildup clogging the fuel injectors or insufficient fuel pressure leading to uneven fuel injection, causing the car to lurch. A dirty air filter can restrict airflow, affecting combustion efficiency. If these problems aren't addressed promptly, not only does driving become uncomfortable, but fuel consumption can also skyrocket, potentially damaging the engine. It's recommended to inspect spark plugs and fuel injectors every 10,000 to 20,000 kilometers. Replacing worn parts can save a lot of hassle—don't wait until you're stranded on the road to panic.
