BMW usually shuts down this type of injection device due to spark plug issues, which can be diagnosed using the swap method. The spark plugs in the N55 engine should be replaced every 60,000 kilometers. Introduction to the injection device: The water mist direct injection cooling system can significantly improve efficiency when the engine is under full load. It avoids rich fuel injection and reduces exhaust temperature. It can reduce daily driving fuel consumption by up to 8%. Lower exhaust temperatures also reduce the production of harmful substances. Fuel compatibility: Optimal power output can be achieved even with low-octane 95-grade fuel; therefore, turbocharged engines equipped with the water mist direct injection system are suitable for use worldwide.

How Long Should a Battery Be Charged?

When the battery of an electric vehicle is completely drained, it is recommended to charge it for approximately 7 to 8 hours. Around eight hours is sufficient to fully charge the battery without overcharging, which could lead to risks such as battery swelling or even explosion due to excessive charge. The number of charge and discharge cycles for an electric vehicle battery is limited. Normally, a battery can handle 300 to 500 cycles without issues, but exceeding 500 cycles may degrade the battery's quality and reduce its storage capacity. This is because the current reaction during charging and discharging can decrease the electrolyte inside, increasing resistance and reducing storage capacity, making the battery less durable over time. Therefore, it is perfectly fine to charge the battery only when it is out of power, as this helps minimize the number of charging cycles and maintain the battery's quality.

How long does it take for a seized vehicle to become locked?

A seized vehicle can become locked at any time if the dispute is not resolved within the specified period. As long as the seized vehicle is not physically impounded, it can still be driven on the road, but changes, transfers, etc., are not allowed. To release the seizure of the vehicle, the respondent must fulfill the judgment or provide other guarantees. If the judgment has been fully executed, you can apply to the court to lift the seizure. After the court issues a release order, take the order to the vehicle management office to lift the seizure. A seized vehicle is one that is prohibited by the court from registration, modification, transfer, mortgage release, cancellation, or pledge release due to economic debt disputes. A locked vehicle cannot be transferred or sold. If such a vehicle is found on the road by law enforcement, it will definitely be impounded. Therefore, when purchasing a vehicle, do not choose one that is in a locked state.
