What to Pay Attention to When Taking Delivery of a Car?

When taking delivery of a car, it is necessary to check the engine, exterior scratches, and other aspects. Below are the specific precautions for vehicle inspection upon delivery: Inspect the body: Visually examine the paint surface of the car body to check for scratches and wear. Observe under sufficient sunlight to see if there is any color difference in the paint. Open the car door and push it to several angles to allow light to shine from different directions, checking if the sheet metal is even. Check the doors: Open the car doors and pay attention to whether they open and close smoothly. Check if the gaps between the doors and between the front and rear bumpers are consistent. Inspect the engine: Open the engine hood and check if the engine compartment is clean. If the car has been stored for a long time or used, there may be obvious dust or stains in some areas. Check the glass: Check if the windshield is original. Check the vehicle nameplate: The car nameplate is located on the side of the driver's door or inside the engine compartment. Pay attention to whether the manufacturing date is too far from the current date. If it exceeds six months, the car is likely to be a stock vehicle or a test drive car.

What does TC stand for?

TC in a car stands for Traction Control System. Here is some relevant information: Introduction to Traction Control System: The Traction Control System, also known as the Anti-Slip Regulation system. When a car brakes on a slippery surface, the wheels may skid, and the direction may even become uncontrollable. When the car starts or accelerates rapidly, the drive wheels may also skid, and on slippery surfaces such as ice and snow, this can lead to dangerous loss of control. The Traction Control System is designed to address this issue. The system relies on electronic sensors to detect when the driven wheels are moving slower than the drive wheels. It then sends a signal to adjust ignition timing, reduce throttle opening, decrease fuel supply, downshift, or apply brakes to the wheels, thereby preventing wheel skidding. How the Traction Control System Works: The Traction Control System works by replacing the mechanical connection between the accelerator pedal and the throttle with an electronic throttle control device. Sensors transmit the accelerator pedal's information to the ECU. The ECU then generates a control voltage signal based on this input. A servo motor adjusts the throttle according to this signal, reducing throttle opening and controlling wheel skidding. For drivers operating their vehicles in rainy or snowy conditions, this system can help minimize skidding or loss of control.

How to Avoid the Rear of the Car Exceeding the Line When Reversing into a Parking Space?

Methods to avoid the rear of the car exceeding the line when reversing into a parking space include: 1. When reversing to the right, slightly adjust the steering wheel to the left instead of turning it all the way to the right; 2. Continue reversing and straighten the wheel when the left side of the car is almost parallel to the left side of the parking space; 3. Make minor adjustments after entering the parking space—steer in the direction the rear of the car is leaning; 4. If the steering is turned too early, the angle between the wheels and the right side of the parking space will be small; 5. If continuing to reverse would cause the car to hit the right side of the parking space, straighten the wheel in time and reverse a bit further; 6. When the left side of the car is almost parallel to the left boundary line of the parking space, straighten the wheel. Reversing into a parking space is a mandatory test item for obtaining a small car driver's license, assessing the driver's ability to maneuver the vehicle in a confined space. It is a key evaluation point in the driver's test, requiring the driver to correctly reverse the vehicle into the parking space from both sides while in motion.

What does it mean when the EPS light is on? Can I continue driving?

EPS stands for Electronic Power Steering, which uses an electric motor to assist the driver in steering. The components of EPS vary slightly between different vehicles, but generally include a torque (steering) sensor, electronic control unit, motor, reducer, mechanical steering gear, and battery power source. When the EPS light illuminates, it indicates a fault in the electric power steering system. Symptoms may include heavy steering, unusual noises when turning, steering wheel vibration, or poor steering wheel return capability. It is recommended to promptly visit an auto repair shop for inspection. In such cases, you should safely stop the vehicle as soon as possible and contact a 4S dealership or professional auto repair service, preferably arranging for a tow truck. Unlike hydraulic power steering systems where the hydraulic pump operates continuously during engine operation (increasing fuel consumption by 3%-5%), EPS uses battery power and an electric motor, operating independently from the engine with minimal direct fuel consumption. EPS eliminates hydraulic fluid leakage issues associated with hydraulic power steering systems. Being electronically controlled, EPS is environmentally friendly with lower fuel consumption. Its compact design integrates major components, requiring fewer parts than hydraulic systems (no oil pump, pipes, control valves, or reservoir), making installation easier and more efficient. While hydraulic systems typically operate at 60%-70% efficiency, EPS can achieve over 90% efficiency.

What is the Difference Between Night Vision Devices and Thermal Imaging?

The biggest difference between night vision devices and thermal imagers lies in their working principles: thermal imagers convert invisible infrared energy emitted by objects into visible thermal images, while night vision devices rely on an image enhancement system to actively receive light sources. They require external light sources to illuminate the object and reflect back to the night vision device for multiple receptions before an image can be formed. The effects are different. If you have used a regular night vision device, you will notice that the observation experience is completely different from that of a standard infrared thermal imager. This is because typical night vision devices observe the target directly through the lens, resulting in a circular field of view with a green-tinted image, similar to what you see through a telescope lens. If the clarity is sufficient, it may be possible to identify who the target is or even discern facial features. In contrast, infrared night vision thermal imagers display images on an internal LCD screen rather than directly observing the target, so the field of view is square. The imaging of an infrared night vision thermal imager is based on temperature distribution. Higher temperatures appear brighter, while lower temperatures appear darker. The primary purpose is to locate the target and determine its category, such as distinguishing between humans and animals. The impact of lighting conditions differs: second-generation night vision devices are more affected by environmental factors due to their imaging principles, especially lighting conditions. When the light dims, the observation distance shortens. In complete darkness, an auxiliary infrared light source is required, but its maximum range is limited to about 100 meters.

Should Chains Use Grease or Engine Oil?

For sealed high-speed movements, it is recommended to use engine oil, while for low-speed movements, grease is suggested. Automotive engine chains, including timing chains and oil pump chains, endure variable speeds and loads. Below is a partial introduction to automotive chains: 1. With continuous advancements in automotive manufacturing technology and industrial development, timing belts in some car engines have been replaced by engine chains. 2. Compared to traditional belt-driven systems, chain-driven systems offer more reliable transmission, better durability, and space-saving benefits. The entire system consists of components such as gears, chains, and tensioning devices.
