Is Gear Grinding Harmful to Cars?

Gear grinding can cause certain damage to the transmission gears. Since car gears are made of metal, mutual friction will inevitably lead to some wear and tear. If gear grinding occurs frequently, it can result in the edges of the gears being worn down, reducing the engagement level during gear shifting. This may cause the gear to disengage with slight vibrations. Inside a manual transmission, there is a crucial component called the synchronizer. The role of the synchronizer is to match the speed of the gear being shifted into with the speed of the output gear during a gear shift, thereby preventing gear grinding.

How to Turn the Steering Wheel Back?

The steps to turn the steering wheel back are: 1. Hold the steering wheel with your left hand at the 9 o'clock position and your right hand at the 3 o'clock position; 2. When turning until both hands are parallel, withdraw your left hand and place it at the current 3 o'clock position on the steering wheel, then continue turning left to lock the steering; 3. When returning to the center, do not rush to switch hands. The steering wheel has a total of 3 turns—one and a half turns to lock it and one and a half turns to return it to the center. Therefore, first turn back half a turn, then another full turn. The steering wheel is a wheel-shaped device used to control the direction of cars, ships, airplanes, etc. It is generally connected to the steering shaft via a spline. Its function is to convert the force applied by the driver on the edge of the steering wheel into torque and transmit it to the steering shaft. Using a larger-diameter steering wheel reduces the hand force required from the driver when turning.

Do Electric Vehicles Require Annual Inspections?

Electric vehicles do require annual inspections. For privately-owned passenger vehicles, both pure fuel-powered models and electric models must undergo on-site testing after 6 years of use. Vehicles aged between 6 to 15 years require annual inspections, while those over 15 years old need semi-annual inspections. The main difference lies in the inspection items - pure electric vehicles are exempt from tailpipe emissions testing, but still require functional checks like lighting, exterior appearance, and chassis. After passing the inspection, pure electric vehicles must display the annual inspection sticker on their windshields, just like conventional fuel vehicles, as proof of compliance. Required documents for EV annual inspection: vehicle registration certificate, compulsory traffic insurance certificate, vehicle tax payment or exemption proof, owner's ID card. If processed by an agent, the agent must bring their own ID card.

Does a Car Consume Fuel When Running but Not Moving?

Starting the car and staying stationary will consume fuel because the internal components of the car are in operation. Below is relevant information about idling: 1. Idle State: Refers to a working condition when the engine is running without load. When the engine is running, if the accelerator pedal is completely released, the engine is in an idle state. When adjusting the idle speed, the RPM should not fluctuate abruptly, as this may cause early wear to the engine. It is recommended to have the idle speed adjusted at an automotive repair facility. 2. Idle Speed: The idle speed can be adjusted by modifying the throttle opening size and the idle fuel supply. Generally, the optimal idle speed is the lowest RPM within the idle range where the engine does not shake and maintains good acceleration performance.
