Why does the engine shake at idle but not when accelerating?

Engine shaking at idle but not during acceleration is mainly caused by changes in fuel injection quantity, throttle carbon deposits, spark plug failure, and other reasons. The common causes are as follows: 1. Changes in fuel injection quantity: This leads to fluctuating engine speeds, causing the engine to shake at idle. 2. Sensor malfunction: Issues with the fuel pump pressure regulator or sensors can result in faulty fuel injection correction signals. 3. Dirty throttle: Carbon deposits or dirt on the throttle, or incorrect positioning of the throttle position sensor. 4. Spark plug failure: Prolonged use of spark plugs can cause increased spark plug gaps or excessive carbon buildup at the ignition point, leading to poor sparking or insufficient ignition energy, resulting in cylinder misfires, reduced power, and engine shaking.

Is annual certification required for B2 every year?

The prerequisite for B2 requiring annual inspection is whether there are any violation records during the current scoring cycle (starting from the date of issuance, with one year as a cycle). If there are violations, annual inspection is required; if there are no violation records, annual inspection is not needed. The specific situations requiring annual inspection are as follows: 1. Points deduction: If points are deducted, annual inspection is required. You must go to the vehicle management office for an annual inspection of your driver's license within 30 days after the end of the current scoring cycle; if no points are deducted during a scoring cycle, annual inspection is not required. If you can maintain no points deduction until the expiration of your license for renewal, no annual inspection is needed. 2. Age over 60: Those over 60 years old need annual inspection every year and must submit a health certificate.

How Many Years Can a Car Be Used Before It Is Scrapped?

For 5-seat family cars and 7-seat SUVs, as well as non-commercial small and mini vehicles, there is no usage lifespan limit. However, when the normal mileage reaches 600,000 kilometers, the state will guide the vehicle to be scrapped. In addition to the above vehicles, small and mini non-commercial passenger cars, large non-commercial cars, and wheeled special machinery vehicles also have no usage lifespan limit. Commercial vehicles have a scrapping lifespan, as follows: Small and mini taxi passenger cars have a scrapping lifespan of 8 years, medium-sized taxi passenger cars have a scrapping lifespan of 10 years, and large taxi passenger cars have a scrapping lifespan of 12 years. Public transport passenger cars have a scrapping lifespan of 13 years, other small and mini commercial passenger cars have a scrapping lifespan of 10 years, and large and medium-sized commercial passenger cars have a scrapping lifespan of 15 years. Mini commercial trucks have a scrapping lifespan of 8 years, light and large commercial trucks have a scrapping lifespan of 10 years. The vehicle scrapping process is as follows: The car owner applying for scrapping and renewal should fill out the "Motor Vehicle Change, Transfer, Modification, Suspension, and Scrapping Approval Application Form" in duplicate and stamp the owner's seal. The registration desk will accept the application and issue a "Vehicle Scrapping Notice" for vehicles that have reached the scrapping lifespan. For vehicles that have not reached the scrapping lifespan, after inspection by the motor vehicle inspection desk, if they meet the scrapping standards, a "Vehicle Scrapping Notice" will be issued. The owner can choose a qualified recycling company to dismantle the vehicle with the "Notice". The recycling company will dismantle the vehicle and take photos after verifying the "Notice". The engine must be separated from the vehicle, the engine block must be broken, and the frame (chassis) must be cut. The owner should submit the "Change Form", "XX Province Vehicle Renewal Technical Appraisal Form", "Scrapped Vehicle Recycling Certificate", and photos of the dismantled vehicle to the motor vehicle inspection desk for verification and signature. The license plates and certificates will be reclaimed, and the scrapping registration will be processed according to regulations after approval. Special Notes: According to Article 30 of the "Motor Vehicle Registration Regulations", if the vehicle is damaged and cannot be driven back to the registration location, the owner can hand over the scrapped vehicle to a local motor vehicle recycling company. If a commercial vehicle is converted to a non-commercial vehicle, it must be scrapped according to the original commercial vehicle's scrapping time. According to Article 43 of the "Motor Vehicle Registration Regulations", after completing the transfer or cancellation of motor vehicle registration, the original owner can apply to the vehicle management office to use the original license plate number when registering a newly purchased vehicle. The application to use the original license plate number must meet the following conditions: (1) The application must be submitted within six months after the transfer or cancellation registration; (2) The owner must have owned the original vehicle for more than three years.

Can a Newly Purchased Car Be Driven on the Highway?

A new car can be driven on the highway, but there are several precautions to keep in mind: 1. Maintain a reasonable speed: Avoid driving too slowly or accelerating too quickly with high RPM. It's best to keep the speed below 100 km/h and monitor the engine RPM and speedometer during the drive. The engine RPM should preferably not exceed 3,000. 2. Avoid using only D gear for automatic transmission cars: Make proper use of S gear and manual mode, which is more beneficial for the transmission. 3. Avoid overloading the car: Do not floor the accelerator when starting or slam on the brakes, as this can damage mechanical components. Emergency braking can shock the braking system and increase the impact load on the chassis and engine.

How many liters of brake fluid is needed for a complete replacement?

A complete brake fluid replacement requires 1 liter. Methods to determine if brake fluid needs replacement are: 1. Open the brake fluid reservoir cap; if the fluid appears turbid or black, it needs replacement; 2. Drive at a normal speed above 40km/h and perform a hard brake; if the braking distance significantly increases, replacement is needed; 3. If the brakes feel soft or unstable during normal driving, replacement is required. Reasons for replacing brake fluid include: 1. Moisture or impurities from the air can enter through the reservoir vent, lowering the boiling point of the brake fluid; 2. During prolonged braking, the brake lines can develop vapor lock, leading to reduced braking force or brake failure.

When Will I Receive the Notification After Running a Red Light?

After running a red light, the text message for the violation captured by surveillance cameras is usually received within 3 to 7 days, with a maximum delay of about 13 days. However, some cities now offer "instant electronic police capture alerts," where you can receive a text notification within 5-10 minutes of being captured. However, this notification does not confirm a violation; it merely serves as a capture alert. The final determination of whether it constitutes a violation takes 3-7 days. If it is indeed a violation, you will receive another text message. For traffic violations captured by surveillance cameras, vehicle owners generally do not receive the violation text message immediately. There is a delay, and the duration may vary. After the electronic camera captures the violation, the relevant violation information needs to be transmitted through a dedicated channel to the traffic police management center. It is then compiled and verified by relevant staff. Once confirmed as a violation, the system automatically retrieves the vehicle owner's phone number based on the license plate information and sends the violation details via text message. After receiving the violation text message, the vehicle owner must go to the traffic police department where the violation occurred within one month before the vehicle's annual inspection to handle the matter. Generally, if a vehicle owner suspects a violation, they can use 15 days as a benchmark. If no violation text message is received beyond 15 days, it is likely that no violation was recorded. Traffic Violation Query Methods: Traffic violation queries refer to checking motor vehicle violations of traffic regulations through online platforms or query terminals. Methods include website queries, phone queries, text message queries, and mobile app queries. Website Query: Search for "vehicle violation query" and input the vehicle information to check. Phone Query: Dial local 114 (area code + 114) or 12580 to confirm traffic violations. Violations can only be processed at the traffic police department where the violation occurred or where the vehicle is registered. For on-the-spot violations, such as those directly caught by traffic police, they must be handled at the violation location. Text Message Query: Open the text message interface on your phone, enter "WZ [license plate number] [plate color]" in the message body, and send it to 1062650001. Mobile App Query: Open the "Traffic Management 12123" app, select "Violation Query," and clear any unresolved violations.
