How to Avoid Blind Spots While Driving?

Here are detailed instructions for identifying blind spots while driving: 1. Rear Blind Spot: Before getting into the car, observe the surroundings to check the terrain and obstacles. While driving, frequently monitor the movement of vehicles and pedestrians in the rearview mirrors. When reversing, use both the interior and exterior rearview mirrors. 2. Right-side A-pillar Blind Spot: Before making a right turn, check the road conditions on the right side. Activate the right turn signal and honk the horn, then proceed slowly while leaning forward to observe the right-side road conditions. When starting from a red light, do so slightly slower and avoid stopping beside large or tall vehicles on the right. Never rush to start when the light turns green. 3. Right-side B-pillar Blind Spot: Avoid making sharp lane changes. Before changing lanes, activate the turn signal and honk to alert nearby vehicles. Check the right-side mirror and turn your head to confirm road conditions, then change lanes safely by steering appropriately.

Definition of wheel bearings: These are components used at the vehicle axle to bear weight and provide precise guidance for the rotation of the wheel hub. They withstand both axial and radial loads and are an important part of the vehicle's load-bearing and rotation. 2. Composition and installation of wheel bearings: Traditional automotive wheel bearings consist of two sets of tapered roller bearings or ball bearings combined.

What Causes Jerking Sensation While Driving?

Jerking sensation during driving is caused by factors such as clogged air filters. Below are detailed explanations of the specific reasons for jerking sensation while driving: 1. Excessive carbon deposits: Heavy buildup of carbon deposits in the throttle body, fuel injectors, and intake manifold. This can cause jerking sensations, so regular carbon cleaning is recommended. 2. Low fuel quality: Substandard fuel quality leads to incomplete combustion, resulting in jerking. 3. Component failure: Issues with spark plugs, ignition coils, etc., causing misfires. These require professional inspection and timely repairs to prevent further safety hazards. 4. Clogged air filter: Long-term neglect of air filter cleaning allows excessive dust into the combustion chamber. The dust can easily adhere to various components when mixed with atomized fuel at the throttle body, leading to jerking.
