No, it is advisable to run the air conditioning for about 15 minutes when the car is parked. Running it for too long can lead to poor heat dissipation and damage to the car engine. Here are some precautions for using car air conditioning: 1. Do not sleep with the air conditioning on: In relatively enclosed environments, such as garages, it may cause carbon dioxide poisoning. It is best to turn on the air conditioning in open or well-ventilated areas and leave a small window gap. Shortly after entering the car, you should open the windows or turn on the external circulation ventilation system to introduce fresh air. Do not drive for long periods with the windows and doors closed, and never sleep or rest for extended periods in a sealed car. 2. Maintain air exchange between inside and outside: After purchasing a new car, you should try to maintain air exchange between the inside and outside of the car, just like with a newly renovated house, to allow harmful gases inside the car to volatilize and dissipate as soon as possible.

What Causes the Vibration in a Newly Replaced Engine?

The reasons for vibration in a newly replaced engine: excessively high oil viscosity, insufficient belt tension, poor fuel quality, and engine cold starts can cause car vibration even with a new engine. Common causes of car vibration include a dirty throttle body or excessive carbon buildup in the fuel injectors. When there is too much carbon buildup inside the engine, the gasoline sprayed by the cold start injector can be largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts, making it difficult to start. If the engine vibration increases, it may be due to issues with the engine mounts. The connection points between the engine and the frame are equipped with engine mounts made of rubber material, which prevent the vibrations from the engine operation from being directly transmitted to the car body.

Can You Drive If the Generator Is Broken?

You can drive if the generator is broken, as long as the battery has enough power to start the car. The car's starting process is completed by the starter motor driving the engine, after which the engine drives the generator to recharge the battery. The car generator is the main power source of the vehicle, functioning to supply power to all electrical devices while the engine is running normally, and simultaneously charging the battery. The working principle of the generator is as follows: when an external circuit energizes the excitation winding through the brushes, a magnetic field is generated, magnetizing the claw poles into N and S poles. As the rotor rotates, the magnetic flux alternates in the stator windings, and according to the principle of electromagnetic induction, an alternating induced electromotive force is generated in the three-phase windings of the stator.
