ETC displays a card read error for the following reasons: When passing through the ETC lane, the speed is too fast, and the information is not fully read. The signal between the device and the lane antenna is weak. The ETC card or onboard device is faulty. It is recommended to check it. How ETC works: Through the onboard electronic tag installed on the vehicle's windshield, it communicates with the microwave antenna in the ETC lane at the toll station via dedicated short-range communication. The computer network technology is used to process background settlements with the bank, enabling vehicles to pass through highway or bridge toll stations without stopping while paying the toll. ETC installation location: For small vehicles such as cars and minivans, the ETC card and OBU device are installed in the upper middle part of the front windshield. For large vehicles such as trucks and buses, the installation location is in the lower middle part. ETC installation requirements: The height should not be less than 1.2 meters or more than 2.5 meters; the installation angle N should be between 30º and 90º (the angle between the surface of the electronic tag and the horizontal plane).

What type of engine oil does the Changan Raeton CC use?

sn-level 5w30 viscosity grade full synthetic engine oil is the type used in the Changan Raeton CC. If you want to change the oil during later maintenance, you can choose brands such as Mobil or Castrol. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand low temperatures of -30°C. The smaller this number, the better the low-temperature fluidity, ensuring smoother cold starts for the car in low temperatures. The latter number represents the kinematic viscosity of the oil at 100°C. The higher the number, the better the oil maintains its viscosity index at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil in the Changan Raeton CC is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan to catch the old oil until no more oil flows out. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain out; Use a special wrench to remove the oil filter; Apply some oil to the seal of the new oil filter and tighten it clockwise by hand; Add the new engine oil through the oil filler cap on the engine valve cover. Generally, fill about three-quarters of a standard oil container; Start the engine and let it run for 5 minutes, then check for any oil leaks around the oil drain plug and oil filter. If there are leaks, perform necessary repairs; After stopping the engine, pull out the oil dipstick and check that the engine oil level is within the standard range.

What are the components of the engine valve train?

Engine valve train can be divided into two main parts: the valve group and the valve drive group. Here are the detailed explanations: 1. The valve group includes the valves and their associated components, whose composition is basically independent of the type of valve train. 2. The valve drive group consists of all components from the timing gear to those that actuate the valves, and its composition varies depending on the type of valve train. Its function is to drive the valves to open and close at the correct timing. 3. According to operational requirements, it timely opens and closes the intake and exhaust valves to introduce combustible gas into the cylinder and expel exhaust gases. At the same time, it drives components such as the distributor and fuel pump to operate.

Why Does the Door Stopper Make Noise?

The reason for the abnormal noise from the door stopper is lack of lubrication. The simplest solution is to use lubricants such as grease for lubrication and rust prevention, reducing friction and wear on mechanical components and extending fatigue life. Below are the relevant details: 1. The function of the door stopper is to limit the degree to which the door can open. 2. On one hand, it restricts the maximum opening angle of the door, preventing it from opening too wide; on the other hand, it keeps the door open when needed. 3. There are two common types of door stoppers: torsion spring stoppers and tension spring stoppers. 4. In terms of both production and maintenance costs, tension spring stoppers are superior to torsion spring stoppers.

What is the validity period of a car fire extinguisher?

The shelf life of a car fire extinguisher is as follows: the extinguisher cylinder has a validity period of 8 years; the extinguishing agent has a shorter validity period, around one year. Therefore, car owners should regularly check the condition of the fire extinguisher. Below is the relevant information: 1. Currently, the main types of car fire extinguishers on the market include dry powder fire extinguishers, ultra-fine dry powder fire extinguishers, carbon dioxide fire extinguishers, and water-based fire extinguishers. 2. However, dry powder fire extinguishers are the most commonly used. Dry powder fire extinguishers use carbon dioxide liquid or nitrogen to spray dry powder for fire extinguishing. 3. Car fire extinguishers are equipped with a pressure gauge. If the pointer on the gauge is within the green range, it indicates normal pressure and proper functioning; if it is in the yellow range, it indicates excessive pressure, and if it is in the red range, it indicates insufficient pressure. Both conditions can affect the fire extinguishing performance, and the extinguisher should be replaced promptly. When using the extinguisher, aim directly at the fire source.
