The installation process for a car ETC device is as follows: Upon receiving the device, first check if the ETC card and the electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU; a red light will briefly illuminate, and the OLED screen will display "Tag Invalid" or "Please Insert Card," indicating the device is functioning normally. Clean the front windshield, ensuring the glass surface is smooth, clean, and dry. Then, peel off the adhesive backing of the OBU and stick it to the installation position. Press firmly for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front side facing the driver and the back side facing the windshield, ensuring the chip is inserted into the OBU device. Where can the ETC be installed: For small vehicles like cars and minivans, the OBU device should be installed in the upper middle part of the front windshield. For large vehicles like trucks and buses, the installation position is in the lower middle part. ETC installation position 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).

Can new energy vehicles keep the air conditioning on while parked?

New energy vehicles can keep the air conditioning on while parked. Here are some precautions for using new energy vehicles: Avoid storing the vehicle with a low battery: The battery must not be stored in a depleted state. If the battery is used up, it should be recharged promptly. Master the correct charging time: During use, the charging time should be accurately determined based on actual conditions, considering factors like frequency of use and driving distance to determine the charging frequency. Regularly check tire pressure: Maintain the correct tire pressure and check it every two weeks or at least once a month. Incorrect tire pressure can lead to increased power consumption, reduced driving range, decreased driving comfort, shortened tire lifespan, and compromised driving safety. Avoid exposure to direct sunlight: High temperatures can increase internal battery pressure, causing water loss, reduced battery activity, and accelerated aging of the plates. Therefore, electric vehicles must not be exposed to direct sunlight and should be parked in shaded areas.

What are the methods for treating diesel vehicle exhaust?

You can appropriately increase the fuel injection quantity and add cleaning agents to the fuel to significantly reduce the smoke opacity value. Component inspection: If the power at the wheels meets the standard but the emission values do not comply, this situation is relatively easier to resolve. You can try adding cleaning agents such as smoke eliminators or adding repair agents to the lubricating oil. If the diesel vehicle's emission values are severely exceeded, it is necessary to check whether the fuel injectors or cylinders are severely worn or have carbon deposits, requiring timely cleaning or replacement of components. Fuel selection: Diesel vehicle owners should also be careful not to use low-quality gasoline, and pay attention to whether the three-way catalytic converter on the vehicle is damaged. Owners should also pay attention to vehicle maintenance in daily life, as damaged parts during use can prevent vehicle components from functioning properly, leading to unqualified exhaust emissions.

Should You Press the Brake or the Clutch First in a Manual Transmission?

It depends on the specific situation. Below are the relevant details: When driving at high speed: Press the brake first, then the clutch. At high speeds, the brake can effectively stop the car. The speed will decrease rapidly due to braking, and pressing the clutch at this point will improve the stopping effect. The car will come to a more stable halt, and additionally, pressing the brake before the clutch can reduce the wear rate of the brake pads to some extent. Pressing the clutch first at high speeds may prevent the car from stopping, increasing the risk of rear-end collisions. Therefore, at high speeds, always press the brake before the clutch for greater safety. When driving at low speed: Press the clutch first, then the brake. At low speeds, pressing the clutch can generally bring the vehicle to a stop. If the speed is very low, suddenly pressing the brake may cause the car to stall, which can significantly damage the vehicle. Stalling a car in gear generates a strong impact force that can harm the transmission. Therefore, unless it's an emergency stop, at low speeds, you can press the clutch first to slow the vehicle down before applying the brake. This prevents the car from stalling easily and protects the transmission from damage.

What are the main tasks involved in automotive final assembly work?

Automotive final assembly work primarily involves coordinating with product designers on the feasibility of manufacturing processes; resolving technical issues that arise during the assembly process; providing technical support for the modification or upgrade debugging of general equipment for specific vehicle models; and supervising and inspecting the implementation of assembly processes while conducting quality management. Automotive vehicle assembly: The assembly of automotive products (including complete vehicles and assemblies) is one of the most critical process stages in automotive manufacturing. It involves assembling hundreds or thousands of various components that have passed inspection into complete vehicles and assemblies such as engines and transmissions, according to specific technical requirements. Automotive final assembly is the process of combining various automotive parts and components according to specified technical requirements, selecting appropriate assembly methods for combination and debugging, ultimately resulting in a drivable automotive product. The process of automotive final assembly can generally be divided into stages such as assembly, adjustment, road testing, packaging, rework, and warehousing.
