Why does the car shake when driving?

The reasons why the car shakes when driving: The throttle valve is too dirty or the fuel injector has excessive carbon deposits. When there is too much carbon buildup inside the engine, the gasoline sprayed by the cold start injector will be largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts, making it difficult to start and causing the car to shake when driving. Under these conditions, the car will only start easily once the carbon deposits have absorbed enough gasoline to become saturated. After starting, the gasoline adsorbed on the carbon deposits will be sucked into the combustion chamber by the engine's vacuum suction force and burned, which in turn enriches the air-fuel mixture. The engine's combustible mixture alternates between being too lean and too rich, leading to idle shaking after a cold start. If the three factors—fuel, air, and spark—are obstructed or not functioning smoothly, the engine's operation will also become unstable, resulting in shaking.

How long does it take for a new car to be driven on the highway?

A new car can be driven on the highway at any time, just avoid letting the engine run at excessively high RPMs during the journey. New cars have a break-in period right after purchase, during which they can be driven at high speeds as long as the engine is not operated at excessively high RPMs. Running the engine at high RPMs during the break-in period can increase engine wear. After the break-in period, it is recommended to drive the car at high speeds to enhance engine performance. This is because, after the initial break-in, the components of the new engine operate more harmoniously. Driving at high speeds for a period allows testing the engine's extreme working conditions and expands the tensile, compressive, impact, and torsional resistance ranges of the components.

Can people over 70 still drive?

People over 70 can still drive. There is no age limit for driving a C1 car, but it should be noted that once a driver reaches the age of 70, they need to have their driver's license checked annually. Additionally, the driver must submit a "Driver's Physical Condition Certificate" within 30 days after the end of the scoring period. If the "Driver's Physical Condition Certificate" is not submitted, the driver's license will become invalid the following year. After submitting the certificate, if the vehicle management office determines that the driver's physical condition is suitable for continuing to drive, they can continue to drive on the road. If the vehicle management office deems that the driver's physical condition no longer permits driving, the driver's license will be revoked.

What Causes Poor Cooling in Car Air Conditioning?

Reasons for poor cooling performance in car air conditioning include: 1. Dirty air filter: After driving for a period, the air filter accumulates dust, insect remains, etc., significantly reducing airflow and leading to poor cooling; 2. Incorrect refrigerant level: Too much or too little refrigerant in the car's air conditioning system can prevent normal cooling; 3. Dirty condenser reducing heat dissipation: Excessive oil or spring willow catkins clogging the condenser may allow the AC to appear operational while actually diminishing cooling efficiency; 4. Poor-quality window film: Besides AC issues, ineffective heat insulation from window films also contributes to the problem.

What to Do When the Electronic Parking Brake Fails?

Solutions for a failed electronic parking brake include: restarting the vehicle to retry the operation. If the operation fails, it is necessary to go to a repair shop or 4S store for detailed inspection or repair; if the electronic parking brake cannot be released, the vehicle will be unable to move, which is a relatively rare situation requiring a call to rescue services for assistance. If the electronic parking brake malfunctions after replacing the rear brake pads, it is recommended to go to a repair shop or 4S store to rematch the electronic brake. Other faults require checking the circuit from the fuse or the electronic parking brake switch. The electronic parking brake is a technology that achieves parking braking through electronic control, with the same working principle as the mechanical handbrake, controlling parking braking through the friction generated between the brake disc and brake pads, except that the control method changes from a lever handbrake to an electronic button.

How often should the transmission fluid be changed?

Transmission fluid should be changed every two years or every 60,000 kilometers. Automatic transmission fluid cannot be completely drained using atmospheric pressure, and only about half of the used fluid can be removed. The remaining fluid, along with sludge and impurities, accumulates in the valve body, torque converter, and cooling lines, leading to blockages in the system's internal passages. Over 99% of automatic transmission failures are caused by overheating and the accumulation of impurities due to prolonged non-replacement of ATF (Automatic Transmission Fluid). The primary function of transmission fluid is to keep the gear shifting system clean and to lubricate the transmission components, thereby extending their lifespan.
