How to Check the Production Date of Fengfan Battery?

Fengfan battery production date is composed of a series of Arabic numerals and English letters, located on the surface of the battery, representing the year, month, and day of production. The following is a related introduction: 1. Fengfan battery labeled 4A0735331: For example, a Fengfan battery labeled 4A0735331, where 4 indicates production in 2014, and A represents January (A is January, B is February... L is December, and so on), 07 represents the 7th day of the month. In summary, the battery was produced on January 7, 2014. As for the remaining 35331 label, it refers to the production unit code and team number. 2. Precautions for purchase: It is best to purchase the battery from official channels, as there are some small factories in the market that recycle old batteries. The production dates marked on such batteries are basically unreliable, not only lacking a good guarantee in terms of quality (durability) but also lacking overvoltage and overcurrent protection, posing certain safety hazards during charging.

What Causes Engine Idle Fluctuation?

Reasons for engine idle fluctuation: 1. Severe carbon buildup in the engine: Carbon deposits are the main cause of engine shaking. When excessive carbon accumulates inside the engine, the fuel injected by the cold-start injector gets largely absorbed by the deposits, resulting in an overly lean air-fuel mixture during cold starts and making cold starts more difficult. Solution: Regularly clean the fuel system, inspect the idle air control valve, and clean the throttle body. 2. Ignition system malfunction: Spark plugs are wear items that require periodic replacement. If excessive carbon buildup on spark plugs or excessive electrode gap is found, replacement is needed. Additionally, inspect the condition of ignition wires and coils. A vehicle diagnostic computer can be used to assess the ignition system's status. 3. Fuel pressure issues: Check whether fuel supply pressure and intake pressure sensors are functioning properly. Abnormal fuel pump pressure or faulty readings/operation of the intake pressure sensor can both cause engine shaking.

Reasons for the Increased Blinking Speed of Car Turn Signals

Reasons for the faster blinking of car turn signals are as follows: 1. Burnout of the right turn signal (same side): Generally, turn signals include the right front turn signal, right front fender light, cornering light, right rear turn signal, etc. The burnout of any of these bulbs may cause the blinking frequency to become too fast when turning; 2. Poor contact of the right turn signal: Such as loose bulbs, poor plug connections, etc.; 3. Inconsistent power or model of the right turn signal bulb: For example, some car owners replace the turn signal bulbs with bulbs of different specifications or models, or use bulbs with too high or too low power.

What does 'lo' mean in a car?

In a car, 'lo' stands for 'low'. It appears on the temperature control knob of the air conditioning panel, and turning it towards 'lo' lowers the temperature. The steps to use the air conditioning are: 1. Press the one-touch start button to start the vehicle; 2. Press the AC option to activate the air conditioning system; 3. Press the 'lo' or 'gr' indicators to adjust the temperature; 4. Adjust the digital display to set the fan speed. The working principle of the air conditioning is that the compressor sucks in the low-temperature and low-pressure refrigerant gas at the outlet of the evaporator, compresses it into a high-temperature and high-pressure gas, and discharges it from the compressor. The high-temperature and high-pressure superheated refrigerant gas then enters the condenser, where, due to the decrease in pressure and temperature, the refrigerant gas condenses into a liquid, releasing a large amount of heat. The functions of the air conditioning are: 1. Adjusting the interior temperature; 2. Humidity regulation; 3. Airflow adjustment; 4. Air purification.

Is there an 80 km/h speed limit on highways?

Highways have a speed limit of 80 km/h. Driving at speeds slightly above 80 km/h constitutes speeding and may result in camera enforcement penalties. Relevant regulations stipulate that highways must clearly mark speed limits for each lane, with maximum speeds not exceeding 120 km/h and minimum speeds not falling below 60 km/h. Additional information regarding penalty points for ordinary vehicles outside highways is as follows: 1. Exceeding the speed limit by less than 10% incurs no penalty. 2. Exceeding the speed limit by 10-20% results in a 50 RMB fine and 3 penalty points. 3. Exceeding by 20-30% carries a 50 RMB fine and 6 points. 4. Exceeding by 30-50% warrants a 200 RMB fine and 6 points. 5. Speeding 50-70% over the limit incurs a 1,000 RMB fine, 12 points, and possible license suspension. 6. Exceeding the speed limit by over 70% results in a 2,000 RMB fine, 12 points, and potential license revocation.
