What Generally Causes Air-Fuel Ratio Faults?

Where is the front side airbag located?

The front side airbag is typically installed on the outer side of the front seats. Below is relevant information about airbags: Purpose of installing airbags: The purpose is to mitigate injuries caused by side impacts by isolating direct collision between the torso and door panel, effectively protecting the safety of front-seat passengers. Currently, some high-end or high-configuration models are equipped with front side airbags. Composition of airbags: Airbags mainly consist of components such as sensors, microprocessors, gas generators, and the airbag itself. Sensors and microprocessors are used to determine the severity of a collision and transmit signals. The gas generator, upon receiving the signal, initiates ignition, ignites solid fuel to generate gas that inflates the airbag, causing it to rapidly expand (with a capacity of approximately 50-90 liters). Since their introduction, airbags have saved numerous lives. Studies show that in frontal collisions involving vehicles equipped with airbags, driver mortality rates decreased by 30% in large cars, 11% in midsize cars, and 20% in compact cars.

What to Pay Attention to When Driving During the Probationary Period

For the first 12 months after a motor vehicle driver initially obtains a driver's license, it is considered the probationary period. During this time, a uniform probationary period emblem must be displayed on the rear of the vehicle being driven. Regardless of the type of driver's license obtained, the probationary period lasts for 12 months. Key points to note when driving during the probationary period: 1. Driving Alone on Highways is Prohibited During Probationary Period. Many people mistakenly believe that driving on highways is entirely prohibited during the probationary period. In reality, you cannot drive alone on highways; however, if accompanied by a driver with over 3 years of experience in the front passenger seat, it is permitted. Otherwise, a fine of 200 yuan will be imposed. 2. Failing to Display "Probationary" or "Novice" Emblem Results in a 200 Yuan Fine. On one hand, probationary drivers must display a "Probationary" or "Novice" emblem on the rear of their vehicle—failure to do so incurs a 200 yuan fine. On the other hand, driving commercial vehicles, ambulances, rescue vehicles, or other special-purpose vehicles is strictly prohibited. 3. Accumulating 12 Points During Probationary Period Leads to License Revocation. Penalties during the probationary period follow the "Regulations for the Implementation of the Road Traffic Safety Law" without any special considerations. However, it is crucial to note that accumulating 12 or more points during the probationary period will result in the immediate revocation of the driving license for the permitted vehicle type. Once revoked, the driver must reapply, retake the exams, and obtain a new license. 4. No Need to Replace License After Probationary Period Ends. After the first year of the probationary period, there is no need to replace the license. The license can be renewed during the annual review after the 6-year validity period expires (as indicated on the license, renewal should be processed at the local vehicle management office or district traffic police departments within 90 days before the expiration date). 5. Penalty Points System After Probationary Period. For 1-11 points: After paying the fine, the points reset to 12 in the next cycle. For 12 points: 7 days of study and retaking the theory test (Subject 1). For 24 points: 7 days of study and retaking both the theory (Subject 1) and road tests (Subject 3). Note: Extending the probationary period only applies to drivers with a Class B license or higher. Some believe that accumulating 6 points during the probationary period extends it by 12 months, but this rule specifically applies to drivers with Class B licenses or above.

How Often Should the Timing Belt of a Car Engine Be Replaced?

Car engine timing belts should be replaced regularly at intervals of 60,000 kilometers. In addition to the manufacturer's recommended schedule, it's important to consider your own driving conditions. If you notice signs such as reduced hardness, wear, fiber breakage, cracks, or fissures on the belt, it indicates that the belt is damaged and should no longer be used. The timing belt is a crucial component of the engine's valve system. When the engine is running, the piston's stroke, the opening and closing of the valves, and the ignition sequence must remain synchronized through the connection provided by the timing belt. The engine's timing mechanism ensures that each cylinder's piston reaches the top dead center precisely when the valves close and the spark plug ignites.
