What does ECU mean?

ECU in automobiles refers to the Electronic Control Unit, also known as the vehicle computer or onboard computer. In terms of its function, it serves as a dedicated microcomputer controller for vehicles. Common causes of ECU damage are as follows: 1. Not disconnecting ECU wiring: During welding repairs on the vehicle frame, failing to disconnect the ECU wiring can be harmful because the current changes during welding generate extremely high induced electromotive force, which can damage the ECU through the wiring. 2. Direct charging: When the battery is low, using a silicon-controlled rectifier (SCR) charger for direct charging can produce high-order harmonics from the SCR circuit, which may damage the ECU. 3. Excessive electrical voltage: Due to excessively high charger voltage, reversed polarity, or charging while the ignition switch is on or even while starting the generator. 4. Unauthorized disassembly of the ECU: If maintenance personnel disassemble the ECU without proper precautions, touch the control unit interface with their hands, or use a soldering iron without grounding to solder the ECU's CMOS chip, it can lead to electrostatic discharge that may break down the CMOS chip. 5. Sudden disconnection of battery terminals: If the positive and negative terminals of the battery are suddenly disconnected while the engine is running, the circuit can generate a high induced electromotive force, potentially causing the internal electronic components of the ECU to be damaged.

Can Adjustable Suspension Adjust Chassis Height?

Adjustable suspension can adjust chassis height. There are two types of adjustable suspension: one can only adjust the damping force of the suspension shock absorber, while the other can adjust both the stiffness of the suspension shock absorber and the spring. The former is called semi-active suspension, and the latter is called active suspension. Adjustable suspension is divided into active suspension and semi-active suspension. Full active suspension can adjust the stiffness and damping of the suspension in real-time based on the vehicle's motion state and road conditions, ensuring optimal shock absorption. Semi-active suspension only considers changing the damping of the suspension without altering its stiffness. Air suspension refers to a suspension system that uses an air compressor to generate compressed air, which is then used to adjust the ground clearance of the vehicle chassis. Features of adjustable suspension: Unlike traditional suspension systems, adjustable suspension allows the driver to manually or automatically change the height and stiffness of the suspension to adapt to various road conditions, keeping the vehicle in optimal condition at all times. However, due to its high cost, adjustable suspension is typically only found in some high-end vehicles.

How to Deal with Oil Film on Car Glass?

Toothpaste, detergent, and an eraser can be used to handle oil film on car glass. Oil film on car glass not only wastes windshield washer fluid and damages wiper blades but also impairs visibility. Detergent: Ordinary windshield washer fluid often struggles to remove this type of oil film. It is recommended to purchase a specialized oil film remover. Common detergents like dish soap, laundry detergent, or Mr. Muscle are not particularly effective. Toothpaste: Toothpaste can also remove oil stains, but it is important to choose one containing abrasive particles, as this type can better polish the car glass surface and eliminate oil stains. When scrubbing the glass, the abrasive particles come into contact with the surface, enhancing the polishing effect. This is a relatively low-cost method, but it is best to use a towel or sponge for scrubbing to allow the particles in the toothpaste to better polish the glass surface and remove the oil film. Eraser: An eraser can also be used to wipe the glass, but this method is more time-consuming and labor-intensive.

How to Adjust the Seat Forward and Backward?

Lift the adjustment handle located at the lower right side of the seat to release the locking mechanism, allowing the seat to move forward and backward. Once the desired position is achieved, release the handle to secure the seat in place. The correct seat height should be adjusted so that the driver's view is not obstructed by the steering wheel, and all important gauges and street signs are clearly visible. Additional relevant information is as follows: Note 1: The hips should be positioned as far back as possible, ideally touching both the seat cushion and the backrest, ensuring a stable and secure seating position without wobbling. After sitting firmly, pay attention to the placement of your hands and feet. Place your left and right hands at the 9 and 3 o'clock positions on the steering wheel, respectively. At this time, your back should not leave the backrest. If it does, it indicates that you are sitting too far back, and the seat must be moved forward. Note 2: The position of your left and right feet should allow your legs to remain slightly bent even when the pedals are fully depressed. If your legs are straight when the pedals are fully pressed, the seat must be moved forward slightly. It is important to ensure that your knees do not touch the steering column, maintaining a certain distance to avoid affecting foot movement and reaction time.

What is the actual measured ground clearance of the Edge?

The ground clearance of the Edge is 160mm. The minimum ground clearance of the Edge refers to the distance between the lowest point (excluding the wheels) and the supporting plane, which indicates the vehicle's ability to pass over obstacles such as rocks and tree stumps without collision. A higher ground clearance of the Edge improves its off-road capability, but if the ground clearance is too high, the stability at high speeds will decrease. The Ford Edge is a mid-to-large SUV model built on Ford's global mid-size car platform. The first-generation imported Ford Edge made its debut in China on September 15, 2010. The Edge has body dimensions of 4878x1925x1734mm and a wheelbase of 2850mm. Generally, the ground clearance of sedans ranges between 110mm and 150mm, while SUVs have a ground clearance between 200mm and 250mm. However, the Edge's ground clearance is not static; it also depends on the load condition. Therefore, changes in ground clearance should be considered based on the Edge's load variations. When selecting a vehicle, ground clearance can be one of the reference factors. The choice should depend on the vehicle's intended use and road conditions. For urban driving with good road surfaces, a vehicle with lower ground clearance can enhance stability and comfort. If the vehicle is frequently used in remote areas or on poor road conditions, a higher ground clearance may be preferred for better off-road performance to avoid undercarriage scrapes or damage.

What is the tire model of the Corolla?

The tire model of the Corolla is 195/60R15. The first number, 195, indicates that the tire width is 195mm. The 60 represents the aspect ratio of the tire's cross-section, which is 60%, meaning the height of the cross-section is 60% of the width. The 15 denotes the rim diameter of 15 inches. The letters or symbols in between have special meanings: "X" indicates a high-pressure tire; "R" or "Z" denotes a radial tire; "-" signifies a low-pressure tire. The Corolla has a top speed of 180km/h and a fuel consumption of 6.5L per 100km. In addition to the model, tires also display the following common data: Tire cord material: Indicated by Chinese pinyin, such as M for cotton cord, R for rayon cord, N for nylon cord, G for steel cord, and ZG for steel radial cord tires. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under defined conditions. Letters from A to Z represent certified speed ratings ranging from 4.8km/h to 300km/h. Common speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h. Rim specification: Shows the rim size compatible with the tire, facilitating practical use, such as "Standard Rim 5.00F".
