The reasons why the central locking system cannot lock the car are that there is a problem with the central locking system of the motor vehicle, the remote key is damaged, or the vehicle door is not completely closed. If the vehicle lock is malfunctioning, you can try to lock the motor vehicle using the mechanical key. After completing the locking process, make sure the vehicle is indeed locked. Below is an introduction to the automotive central locking system: Central Locking System: There are many types of central locking systems installed in cars, but their basic components mainly include the door lock switch, door lock actuator, and door lock controller. Switch: Most central locking switches consist of a master switch and sub-switches. The master switch is installed on the driver's side door, allowing the driver to lock or unlock all doors of the vehicle. Sub-switches are installed on other doors, enabling individual control of each door. Actuator: The central locking actuator is used to execute the driver's commands to lock or unlock the door. Door lock actuators come in three types: electromagnetic, DC motor, and permanent magnet motor. Their structures all involve changing polarity to reverse the direction of movement, thereby executing the locking or unlocking action.

Why does the FAW J6P have high water temperature when climbing?

Reasons for high water temperature in FAW J6P when climbing: Common causes include damage to electronic components in the cooling system (thermostat, cooling fan), poor radiator performance, insufficient coolant, etc. Solutions are as follows: 1. Do not turn off the engine immediately: Pull over to the side, but do not turn off the engine immediately, as the coolant temperature is already very high, and the cooling capacity has reached its limit. If the engine is turned off immediately, the boiling coolant will stop circulating. Keeping the engine running allows the circulating coolant to still mitigate the impact of high temperature on the engine. 2. Check if there is a shortage of antifreeze: Inspect the coolant circulation to see if it is not flowing smoothly. Additionally, you can check components such as the water temperature sensor, water pump, thermostat, and cooling fan, as any of these could cause the water temperature to rise.

Will the car battery be affected if the car is not used for two months?

Leaving a car unused for two months will affect the battery. The battery charges automatically while driving, but it will still discharge when the vehicle is idle. If the car is not used for an extended period, it is advisable to disconnect the battery cables or start the vehicle every two weeks and drive it for several dozen kilometers to ensure the battery remains functional. Here are some precautions for long-term car battery storage: 1. Timely charging: Check the battery every two weeks during idle periods, such as inspecting the electrolyte level. The battery's electrolyte level should be 10-15mm above the electrode plates; if it is insufficient, add distilled water promptly. Owners can ask friends or family to help maintain the vehicle by starting it for 5-10 minutes every one or two weeks to recharge the battery, while also checking for any other potential issues. 2. Power disconnection: If no one is available to help maintain the vehicle, the negative terminal of the battery can be disconnected to cut off power, preventing energy consumption. Just remember to reconnect the terminal when restarting the vehicle.

What is the difference between National 5 and National 6 vehicles?

The biggest difference between National 5 and National 6 vehicles lies in their exhaust emissions. The National 5 standard sets the carbon monoxide limit at 1000mg/km, while the National 6a standard reduces it to 700mg/km, and the National 6b standard cuts it in half to just 500mg/km. Limits for other pollutants such as nitrogen oxides and particulate matter have also been significantly reduced. Specific details are as follows: 1. The difference in catalytic converters: The National 6 emission standard reduces particulate matter by 67% and nitrogen oxides by 77% compared to National 5, which can be simply understood as "the difference of one catalytic converter." 2. National 6a and National 6b: The National 6 standard is known as the strictest emission standard to date, implemented in phases with two emission limit schemes—National 6a and National 6b—rolled out in 2020 and 2023, respectively. Additionally, key regions with special requirements for atmospheric environmental management can implement the National 6 emission limits ahead of schedule.
