What Causes a Car to Fail to Start?

Here are the reasons why a car may fail to start: 1. Incorrect gear position: Some drivers of automatic transmission cars prefer to keep the gear in D (Drive) while driving and forget to shift to P (Park) when turning off the engine. When attempting to start the car again, it may not start properly because the car cannot start in Drive or Reverse gear. 2. Excessive carbon buildup in the throttle: The throttle usually has a very small space for gas to pass through—just a tiny gap. If this space is blocked by excessive carbon deposits, air cannot flow through, which naturally affects normal starting. 3. Running out of fuel can also prevent the car from starting: Some drivers forget to turn off the engine when parking, and only realize it after a long time. At this point, the car may also have trouble starting. During this period, the car's internal components remain in working condition, and the fuel may be completely depleted.

What to Do If Your Car Insurance Has Expired?

Car insurance is divided into compulsory traffic insurance and commercial insurance. If it's the commercial insurance that has expired, the car owner can renew it at any time; if it's the compulsory traffic insurance that has expired, the car owner must immediately go to the traffic management department to pay for it, otherwise driving with expired insurance may result in penalties if caught. Three key points to note when renewing insurance: 1. Avoid driving without insurance: Insurance companies stipulate that commercial car insurance can be renewed up to 3 months in advance. Some insurance companies also send periodic reminders to car owners before the insurance expires and offer various promotional activities during the renewal period. Compulsory traffic insurance cannot lapse; if caught by traffic police without it, the vehicle will be impounded, and a fine of twice the insurance premium will be imposed. 2. Activate the policy: If renewing a paper policy, the new policy takes effect immediately after the old one expires. However, if renewing an electronic policy, it needs to be activated to take effect. Therefore, car owners with electronic policies should activate them promptly to avoid driving without coverage. 3. Optimal renewal time: To prevent a gap in insurance coverage, it is recommended to renew the insurance about one month in advance to avoid last-minute hassles and ensure a smooth renewal process.

What's the Difference Between Tire Pressure Warning and Tire Pressure Display?

Tire pressure display allows you to visually see the tire pressure, while tire pressure warning is just an alarm system that alerts you when the tire pressure is too high or too low. Abnormal tire pressure can occur due to the following reasons: Abnormal tire pressure: Generally, an alarm will sound if the pressure is below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the tire pressure monitoring system will still record the previous data, causing the tire pressure monitoring indicator to light up. In this case, simply reset the tire pressure. Damaged tire pressure sensor: The tire pressure sensor is used to monitor tire pressure and is installed directly inside the tire, connected to the tire inflation valve. If the tire pressure sensor is damaged during driving, it can also cause the tire pressure warning light to turn on. For sensor damage issues, only a brand-new replacement part can be used.

What Causes the Car to Jerk When Braking?

It is normal for a car to jerk when braking hard, as this is the ABS system in action. If the car jerks when not braking hard, it may be due to uneven surfaces on the brake discs. Below is an introduction to ABS: 1. ABS stands for Anti-lock Braking System: ABS is installed to address the issue of wheel lock-up during braking. Its working principle involves a rapid cycle of braking and releasing, but ABS operates much faster than manual control. Cars equipped with ABS can effectively maintain wheel rotation without locking up, significantly improving vehicle stability during braking and braking performance on poor road conditions. 2. Origin: If the wheels lock up, the car may skid and lose control, making it impossible for the driver to steer or slow down the vehicle. Therefore, engineers developed the ABS to prevent wheel lock-up during emergency braking.

What does pixel headlight mean?

Pixel headlights refer to headlights composed of multiple lighting units that can create image-like illumination effects to enhance driving safety and visibility. Most importantly, they aim to minimize glare for oncoming drivers and pedestrians while achieving clear and long-distance illumination. Introduction to automotive headlights: 1. Positioning: Automotive headlights, also known as car front lights or LED daytime running lights, serve as the "eyes" of a vehicle. They not only affect the owner's external image but are also crucial for safe driving at night or in adverse weather conditions. 2. Function: "Lights" and "horns" serve as communication mediums between vehicles. The "language of lights" in automotive headlights is primarily used during nighttime driving. Proper use of light signals can prevent accidents and serve as "reminders" or "warnings".

What Causes the Clicking Noise When Turning the Steering Wheel in a Baojun Vehicle?

Here are the reasons for the clicking noise when turning the steering wheel in a Baojun vehicle: 1. From the perspective of steering gear mechanics: Many modern vehicles are equipped with vacuum power assistance, which only reduces the driver's steering effort but does not change the actual load on the steering gear itself. Therefore, the most effective way to minimize steering gear wear is to reduce the operational load on the steering gear. 2. Aging poses safety risks: Car owners should develop the habit of turning the steering wheel only after the wheels start rolling. This reduces friction between the tires and the road surface, thereby decreasing excessive load on the steering gear and minimizing wear on the steering linkage system. 3. Long-term stationary steering: This not only places significant stress on the steering gear but also accelerates tire surface wear and shortens tire lifespan. To change this habit, quickly turn the steering wheel as soon as the wheels begin to move slightly, achieving the desired steering control.
