What Causes Excessive Vibration at Idle Speed in a Car?

Here are the reasons for excessive vibration at idle speed in a car: 1. Ignition system issues: Check the working condition of spark plugs, high-voltage wires, and ignition coils. Poor ignition system performance or faulty spark plug firing can cause this type of problem. 2. Unstable fuel pressure: If you've already cleaned engine carbon deposits, throttle body, replaced gaskets and spark plugs, but still notice body vibration at idle, it's recommended to visit a 4S shop to inspect fuel supply pressure and intake pressure sensors. Abnormal fuel pump pressure or faulty intake pressure sensor readings can cause body vibration. 3. Aging engine components: Car vibration can also be related to worn engine mounts. Engine mounts act as the vibration absorption system for the engine, absorbing minor vibrations during operation. If engine mounts fail, these vibrations will transfer to the steering wheel and cabin, causing shaking at idle speed.

Which consumes more fuel, the car's internal circulation or external circulation?

Using internal circulation is more fuel-efficient than external circulation, but in practical use, the difference is negligible. Relevant explanations are as follows: 1. When external circulation is on, the hot air drawn from outside the car is cooled by the air conditioning evaporator before entering the car. The temperature of the outside hot air remains relatively constant before passing through the evaporator and does not change with the duration of air conditioning use. Therefore, this cooling process is relatively slow, requiring a longer time to reduce the car's interior temperature to the set value. 2. When internal circulation is on, the fan directly draws air from inside the car, which is cooled by the air conditioning evaporator and then blown out through the vents. As the interior temperature decreases, the temperature of the air drawn by the fan also gradually lowers. With a constant air conditioning cooling capacity, the temperature of the cooled air blown out from the vents will be lower, creating a positive feedback loop that quickly reduces the car's interior temperature to the set value.

How many kilometers can the Aoling CTS run when the fuel gauge light is on?

The Aoling CTS can run 30 to 100 kilometers when the fuel gauge light is on. Fuel Gauge: It mainly consists of a fuel level sensor and an indicator gauge. The system can continuously monitor the fuel capacity in the tank and estimate how many more kilometers the vehicle can run. Generally, when the fuel gauge light comes on, it serves as a reminder that the fuel level is low and it's time to refuel. In fact, when the fuel gauge light is on, there is still some fuel left in the tank, but it is very little. Fuel Gauge Light On: The vehicle can still run 30 to 100 kilometers. However, if encountering traffic jams or uphill roads, the vehicle may only run 20 to 60 kilometers. Japanese cars, known for their fuel efficiency, can run a bit farther. Actually, having a fuel tank that is either too empty or too full is not ideal. An overly empty tank can damage the fuel pump, while an overly full tank can be dangerous while driving. The optimal fuel level is around two-thirds of the tank capacity.

What are the consequences of suddenly shifting to P gear while driving?

Shifting to P gear suddenly while driving can damage the locking mechanism inside the transmission and also easily damage the gear shift switch inside the transmission. When the vehicle is not completely stationary, never shift directly into P gear, as it can easily cause damage to the pawl inside the transmission. Therefore, the vehicle must always come to a complete stop before shifting into P gear. The following is an introduction to the working principle of the transmission P gear: In fact, the P gear works similarly to the N gear, both of which block the power transmitted from the engine to the wheels by separating the gears. However, the P gear has an additional parking gear and pawl compared to the N gear in terms of structure. When shifted into P gear, the pawl tightly locks the gear on the output shaft, forming a mechanical lock, thereby securing the drive axle and fixing the stationary vehicle.

Why is there no sound from the audio system after the Boyue runs out of battery?

After the Boyue runs out of battery, there may be no sound from the audio system due to connection and setting issues, loose power cable connections to the audio system, uninstalled sound card drivers, or the audio volume being switched to mute. Solutions for the audio system not working: If there are connection and setting issues, first unplug the audio cable from the main unit and try listening with headphones. If there is sound, check if the settings are adjusted correctly. If the power cable connection to the audio system is loose, it may be because the cable is not properly inserted. Simply reconnect the power cable to the audio system. Solutions for the car running out of battery: Check if there are any long-term standby car appliances in the vehicle. If so, the wiring method needs to be changed. If it is not due to car appliances, it is recommended to drive to a local branded battery specialty store to connect to a computer for battery performance testing. If it is a battery level issue, charging will suffice. If it is a performance issue, the battery needs to be replaced.
