When is the highway generally toll-free?

Normally, highways are toll-free during some traditional festivals, but this may vary depending on the specific year. Here are the details about the 2021 highway toll policy: 1. Toll-free periods: According to the "Implementation Plan for Exempting Small Passenger Vehicles from Toll Fees on Major Holidays", the toll-free periods for expressways in 2021 were during the Spring Festival, Tomb-Sweeping Day, Labor Day, and National Day - totaling 4 national statutory holidays and their contiguous rest days as determined by documents from the General Office of the State Council that year. 2. Toll periods: All periods except the Spring Festival, Tomb-Sweeping Day, Labor Day, and National Day. The Dragon Boat Festival, Mid-Autumn Festival, and New Year's Day were subject to normal tolls.

How to Inspect a Vehicle When ESP Cannot Be Manually Turned Off?

When the ESP on a vehicle cannot be manually turned off, it changes the inspection method for vehicle testing. ESP does not require manual activation, and there will be no icon displayed on the dashboard when it is on. However, after ESP is turned off, the dashboard will show the ESP-OFF indicator. Below is an introduction to the components of ESP: 1. Sensors: Sensors generally include wheel speed sensors, steering wheel angle sensors, lateral acceleration sensors, yaw rate sensors, and brake master cylinder pressure sensors. 2. Actuators: Actuators generally include traditional braking systems and hydraulic regulators. 3. Electronic Control Unit (ECU): The electronic control unit interacts with the engine management system and can intervene and adjust the engine's power output.

What Causes Car Vibration While Driving?

If you notice your car vibrating while driving, it is usually caused by tire-related issues. Below is an introduction to the possible causes and solutions for car vibration during driving: 1. Causes: If you observe car vibration while driving, it is typically related to tire problems. This could be due to misaligned tires or poor tire balance. 2. Solutions: You may need to perform a wheel balance or four-wheel alignment. If the car does not pull to one side, a simple tire balance might suffice. Another possible cause is wheel rim deformation due to external impact, which requires inspection at a repair shop to confirm.

Will traffic police check cars with added spoilers?

Adding a spoiler is considered illegal modification, and traffic police will check it. Below are specific details about car spoilers: 1. Overview: A car spoiler refers to the ducktail-shaped protrusion installed at the rear end of the car's trunk lid, which is part of the car's aerodynamic kit. Its main function is to reduce the lift at the rear of the vehicle. 2. Function: The role of a car spoiler is to create downward pressure from air resistance when the car is driving at high speeds, effectively counteracting lift and controlling airflow downforce, thereby reducing the drag coefficient and enhancing the car's high-speed stability. Since spoilers can reduce a car's air resistance, adding a spoiler to high-speed cars can also help save fuel to some extent; it also makes the car's appearance more attractive, serving a certain decorative purpose.

What engine is used in the BYD L3?

The engine used in the BYD L3 is independently developed by BYD and is a domestically produced engine. The 1.8L engine model in the BYD L3 is BYD483QA, with a maximum horsepower of 122, a maximum power of 90kW, and a maximum torque of 160Nm. The 1.5L engine model is BYD473QB, with a maximum horsepower of 107, a maximum power of 79kW, and a maximum torque of 144Nm. For daily maintenance of the BYD L3 engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices in the intake and exhaust systems and usage conditions. For diesel engines, CB--CD grade diesel engine oil should be selected based on mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the engine oil and oil filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, its performance will deteriorate, causing various problems for the engine. To avoid malfunctions, the oil should be changed regularly according to usage conditions, and the oil level should be kept moderate. When engine oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and the oil cannot pass through, the filter may burst or the safety valve may open, allowing the oil to bypass the filter and carry contaminants back to the lubrication area, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, clogging the filter and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

How to Determine if a Car Has Cylinder Scoring?

In daily life, we may encounter the issue of cylinder scoring in cars. Here are specific methods to determine whether a car has cylinder scoring: 1. Speed-based judgment: If a car experiences cylinder scoring, there will be a noticeable jerking sensation while driving. Compared to normal conditions, the car will perform differently when climbing slopes, and the speed will decrease. 2. Engine-based judgment: If a car has cylinder scoring, the engine will produce abnormal noises, similar to a buzzing sound, which is easily noticeable. 3. Fuel consumption-based judgment: If the car shows significantly increased fuel consumption, it might be due to cylinder scoring.
