Why is white smoke coming from the exhaust pipe after changing the engine oil?

White smoke coming from the exhaust pipe after changing the engine oil can be caused by the following reasons: White smoke emission: When diesel engines have delayed fuel injection, low injection pressure, or poor atomization, white smoke may be emitted. During cold starts in winter, white smoke from the exhaust pipe is normal and should gradually disappear after running for a while. Poor fuel injector atomization: Poor atomization can cause incomplete combustion of diesel, leading to white smoke. This can be resolved by repairing the fuel injector. Low cylinder pressure: Some diesel fuel may turn into vapor without being burned, resulting in white smoke from the exhaust pipe. Damaged cylinder head gasket: If the engine has been used for a long time, the cylinder head gasket may be damaged or the cylinder itself may be compromised, allowing coolant to enter the cylinder. In this case, replace the cylinder head gasket and tighten the cylinder head bolts in the correct order using a torque wrench. Alternatively, prolonged engine use may cause uneven contact between the cylinder head and block, requiring the cylinder surface to be machined flat using specialized equipment.

What Are the Hazards of Outdoor Parking?

The hazards of outdoor parking are as follows: Damage to the car's paint: If the car is parked in an open parking lot or a residential parking space, prolonged exposure to sunlight can cause the paint to fade, oxidize, and even crack. Car paint contains a large amount of resin, metal, and other materials, which make it prone to oxidation. Windblown sand and stones can damage the car's glass: If a car is parked outdoors for a long time and encounters windy and sandy weather, the dust and sand particles in the wind can cover the vehicle, causing scratches to the paint and glass. These fine scratches can create diffuse reflections of external light sources on the glass during nighttime driving, severely affecting driving safety. Sand and dust entering the vehicle's interior can increase the failure rate of machinery, leading to higher maintenance costs. Risk of car fire: Some drivers like to place mineral water bottles and lighters in front of the car's windshield. Under the scorching sun, this can easily cause fires and explosions. Engine oil deterioration: If a car is parked outdoors for a long time without use, the engine oil inside will gradually deteriorate and oxidize, leading to issues with lubrication and wear. When the car is started again, it can result in friction or semi-dry friction, accelerating the wear of parts. Additionally, the resistance during startup will increase, making it harder to start the car.

What is the voltage of a BMW battery?

BMW battery voltage is 12V. Normal battery voltage: The normal battery voltage ranges between 11.8V and 12.8V. After starting, the battery voltage should be between 13.2V and 14.8V. As long as the voltage during startup is not lower than 11V, it is considered normal. Both excessively high or low battery voltage can cause certain impacts. Precautions for battery voltage: When charging a lead-acid battery, wear protective clothing. Ensure there are no sparks near the battery during charging, and smoking is strictly prohibited. When charging one or multiple batteries in parallel, the charger voltage should not exceed 16V. Connect the positive lead of the charger to the positive terminal of the battery and the negative lead to the negative terminal. When turning on the charger, start with the lowest current setting and gradually increase it until the battery begins to accept current. For a deeply discharged battery or a battery in cold conditions, this process may take several minutes. If acid mist is emitted from the battery vent or the battery temperature exceeds 52°C, charging must be stopped immediately, as these signs indicate the battery is damaged and needs replacement. Charging is considered complete when the current drops below 1A or after more than 24 hours of charging, at which point charging can be stopped.

Should the transmission fluid be replaced when it reaches the recommended age but has low mileage?

Transmission fluid should be replaced even if the mileage is low when it reaches the recommended age. The optimal maintenance cycle for automatic transmission fluid is every 2 years or 20,000-60,000 kilometers, whichever comes first. Signs that transmission fluid needs replacement include: vehicle shaking, gear shifting hesitation; transmission overheating warning on the dashboard; engine stalling; and unusual noises. The methods for replacing transmission fluid are as follows: Unscrew the drain plug at the bottom of the transmission to drain the old fluid before refilling. Remove the transmission oil pan directly to drain and refill the fluid: this method is more thorough than the previous one, as it removes impurities from the bottom of the oil pan. Use a circulation machine to replace automatic transmission fluid: dynamic fluid replacement with an intelligent circulation machine can filter and clean sludge and impurities inside the automatic transmission. Hazards of not replacing transmission fluid for a long time: 1. Damage to the transmission's gear shift control mechanism; 2. Abnormal wear of gears and clutch plates inside the transmission; 3. Impaired normal operation of the transmission, leading to damage of the transmission valve body.

How many days can a new car be driven without temporary license plates?

A new car cannot be driven on the road without temporary license plates. Below are the methods for displaying temporary license plates on a car: 1. One plate: A single temporary license plate should be affixed to the lower left or right corner of the front windshield, ensuring it does not obstruct the driver's view. 2. Two plates: If there are two temporary license plates, one should be placed on the front windshield, and the other should be affixed to the lower left corner of the rear windshield inside the car. If there is no space on the rear windshield, the second temporary license plate should still be carried in the vehicle. Here is some additional relevant information: 1. Traffic law regulations: Car owners should be aware that temporary license plates are subject to the same traffic laws as regular license plates. Therefore, do not assume that temporary plates allow reckless behavior or that they are too small to be captured by cameras—high-definition cameras can clearly record temporary license plates. 2. Types of temporary plates: There are two types of temporary license plates. One has a sky-blue background with black characters and black borders, which is only valid for driving within the city (local temporary plates). The other has a brown-yellow background with black characters and black borders, allowing for driving across cities (non-local temporary plates).
