Is the 40 km/h Speed Limit on Auxiliary Roads Effective?

How many kilometers should the Qiao Ge change the gear oil?

After 500 kilometers, the Qiao Ge should change the engine oil every 1000 kilometers, and change the gear oil every two engine oil changes. Benefits of changing gear oil: Reduce the wear of gears and other moving parts, and extend the life of gears. Reduce friction and power loss. Disperse heat and play a certain cooling role. Prevent corrosion and rust. Reduce working noise, vibration and impact between gears. Flush away dirt, especially the dirt between the tooth surfaces, and reduce wear. Selection of gear oil: The selection of viscosity should consider both the temperature of the area where it is used and the anti-wear and transmission properties. Use 75W oil in winter and 90 oil in summer. The difference in viscosity is only to consider the anti-wear and transmission properties, while the lower viscosity gear oil in the manual transmission makes the feeling of shifting gears when the car is cold much better, but the anti-wear and noise are sacrificed a lot.

What is the function of a motorcycle spark plug?

The function of a spark plug is to generate a high-voltage electric spark to ignite the compressed combustible mixture. It ensures the normal operation of the engine, and without it, the vehicle would fail to start. If the spark plug is well-maintained, the vehicle will be very fuel-efficient, run quietly without noise, and be motorcycle-friendly. Spark plug maintenance precautions: Always keep the spark plug insulator clean and dry. During normal use, dust, oil, and other deposits may accumulate on the spark plug insulator. These deposits can form external leakage paths, affecting the normal sparking of the plug. When servicing the engine or performing other operations, be careful not to bump the spark plug insulator, as it may crack under force and impair the spark plug's normal function. When connecting or disconnecting the high-voltage wire, handle it gently and avoid excessive force. Do not shake the spark plug insulator, as this may compromise the plug's sealing or cause damage. New spark plugs or those removed for cleaning and inspection must not be dropped or thrown, as this may damage the insulator.

What are the methods for detecting car electrical leakage?

Methods for checking car electrical leakage: Observe the color of the battery observation hole to check if the battery's appearance is intact and whether there is any leakage. Measure voltage and power generation: Use a multimeter to measure the battery voltage and power generation to see if they are normal. The normal voltage should be above 12 volts, and it should not drop below 10 volts after continuous discharge for 10 seconds. Observe the ammeter reading: Remove the negative terminal of the battery, set the multimeter to the current measurement mode, connect the red probe to the battery's negative terminal wire, and the black probe to the negative terminal post. Observe the ammeter reading and compare the measured current value with maintenance data to see if it is within the normal range. If the measured current value is too high, it indicates an electrical leakage fault in the car. Check relays and fuses: Turn off all electrical devices in the car, ensure the doors and trunk are locked, disconnect the negative terminal of the battery, wait for 20 minutes, then connect one end of a test light to the battery's negative wire and the other end to the battery's negative post. If the light turns on, it means the electrical devices and circuits are still leaking. In this case, check the relays and fuses.

What to Do If the First Car Maintenance Is Overdue?

If the first car maintenance is overdue, you can call and communicate with the 4S dealership. If there was prior communication or the overdue period is not too long, the 4S dealership will generally still provide the first free maintenance service. However, if the 4S dealership refuses to offer free first maintenance, there is little that can be done. If the car exceeds the first maintenance period or the specified mileage, the 4S dealership has the right to refuse free first maintenance. First Car Maintenance Items: Replacement: Replace engine oil, oil filter, fuel filter, and air filter. Inspection: Check the coolant level; check the brake and clutch fluid levels; check the power steering fluid level; inspect all oil pipe interfaces for leaks; check the battery fluid level and windshield washer fluid level; inspect the tension and aging of the generator, air conditioning, water pump, and power steering pump belts; check the functionality of front and rear lights; inspect tire pressure and wear; check if the car's exhaust emissions meet standards.

Is a new car inspected every three years?

New cars do not require annual inspection for the first three years; they only need an inspection after six years. Although annual inspections are not required during this period, it is necessary to obtain an inspection compliance label every year. For non-commercial passenger vehicles, new cars are exempt from inspection for the first six years, after which an annual inspection is required. Vehicles eligible for the six-year inspection exemption policy: The vehicle must be non-commercial; the approved seating capacity must be six or fewer; the vehicle type specified on the driving license includes: sedan (mini, small, medium, large), mini ordinary passenger vehicle, mini off-road passenger vehicle, small ordinary passenger vehicle, small off-road passenger vehicle, small special-purpose passenger vehicle. Important notes: If a new car does not meet the conditions for the six-year inspection exemption, it must follow the standard procedure. This involves taking the vehicle to an inspection station for examination, obtaining an inspection certificate upon passing, and then submitting the required documents (ID card, driving license, vehicle and vessel tax or tax exemption certificate, compulsory traffic insurance policy) to the service window to receive the annual inspection label.

What does 15T mean for a car?

15T represents a 1.0T turbocharged engine. This displacement designation is used by Buick vehicles, where 15T, 18T, 20T, and 28T indicate different engine displacements. 15N stands for a 1.5 multi-point fuel injection naturally aspirated engine, 15S represents a 1.5 direct injection naturally aspirated engine, and 15T denotes a 1.0T turbocharged engine. Engine Displacement: Engine displacement refers to the total volume of all cylinders in an engine. It is the working volume swept by the piston moving from the top dead center to the bottom dead center. If an engine has multiple cylinders, the car's displacement is the sum of the working volumes of all cylinders. Engine Overview: An engine is a mechanical device that converts other forms of energy into mechanical energy. The engines used in cars are internal combustion engines, which are heat engines where fuel burns inside the engine. There is a certain relationship between displacement and fuel consumption, but a car with high fuel consumption does not necessarily have a large displacement. To some extent, the size of a car's displacement does not always correlate directly with its fuel consumption.
