It refers to the switching between two-wheel drive and four-wheel drive controlled by a computer chip. On normal road surfaces, the vehicle operates in two-wheel drive mode. When encountering off-road conditions or wheel slippage, the computer detects and automatically distributes power to the other two wheels. Here is additional information: Part-time four-wheel drive: Electric four-wheel drive (automatic transmission) is electronically controlled, while manual four-wheel drive (manual transmission) is fully mechanically controlled. Since electric four-wheel drive uses a computer chip to control the switching between two-wheel and four-wheel drive, this places higher demands not only on the quality of car parts but also on the control program, which affects the intelligence of the drive mode switching. Disadvantages: Although electric four-wheel drive can enhance the vehicle's control over the tires, it still has certain disadvantages on high-intensity unpaved roads. With today's advanced technology, electric four-wheel drive, as an emerging technology, will continue to improve and advance on existing technologies.

Does the 2017 Bora have a rear anti-collision beam?

2017 Bora is equipped with a rear anti-collision beam. Here is the relevant information: 1. Since the rear anti-collision beam is hidden inside the rear bumper, many car owners are completely unaware that their vehicle does not have a rear anti-collision beam installed, nor do they understand the role of the anti-collision beam. In fact, the function of the rear bumper is to absorb impact force. For minor collisions, it is designed to sacrifice the rear bumper to ensure the integrity of the vehicle's chassis and prevent deformation. 2. Without a rear anti-collision beam, the protection against minor collisions is precisely what is missing, leading to greater damage to the vehicle body because the rear vehicle directly impacts the rear part of the axle through the plastic bumper.

When is the best time to replace a private car?

Here is the relevant introduction about replacing a private car: 1. The configuration level of the old car cannot keep up. With the advancement of science and technology, more and more high-tech configurations are being incorporated into cars. At this point, the configuration of the old car lags behind the current technological level, and it may not fully meet the usage needs of consumers. Therefore, replacing the car becomes a necessary step. 2. Decline in car performance and increase in maintenance frequency. A car is a consumable product. During prolonged usage, internal components may wear out or age, leading to a decline in the car's performance. At the same time, frequent trips to the repair shop can be both costly and troublesome. At this stage, it is advisable to replace the underperforming car to avoid potential hazards to driving safety.

What Causes Shaking When Lightly Pressing the Brake, But Not When Pressing Hard?

Here is an introduction to vehicle shaking when pressing the brake: 1. Lightly pressing the brake causing vehicle shaking may indicate an issue with the brake disc. 2. There might be a problem with the wheel hub. If the wheel hub is faulty, the corresponding wheel may not run on a flat plane, leading to shaking when braking. Below is an introduction to steering wheel shaking when braking: 1. Slight vibration in the steering wheel when pressing the brake is normal due to the influence of road resistance coefficient and vehicle deceleration. 2. However, if you slowly press the brake pedal at around 60 mph and feel shaking first from the pedal, followed by the steering wheel swinging as the pedal force increases, you should measure the runout of the brake disc. If the edge of the disc has significant runout, the brake disc and pads should be replaced. 3. If the front of the vehicle shakes when braking, you should check whether the tie rod ball joint and lower control arm ball joint have excessive play.

How to disassemble the key of Zotye Z300?

The key circuit board shell is usually composed of two interlocking halves. Pry it open from the middle seam to see the circuit board and the button battery, then replace it with a new one. Here are some related information about Zotye Z300: 1. The Zotye Z300 is equipped with Mitsubishi 1.5L/1.6L all-aluminum high-efficiency engines, providing strong power. With the muscular lines on the front and rear bumpers, smooth body lines, and newly designed alloy wheels, the overall shape is very dynamic. The 2016 Z300 basically continues the design of the 2014 Z300 New Vision edition, but with some adjustments in details. The 2016 version adds chrome-plated borders for the front fog lights, chrome window trims, and chrome-plated exterior door handles. In addition, the four-wheel brake calipers of the new car are painted red, and the tail logo has also been optimized. 2. Its body dimensions are: length 4565mm, width 1766mm, height 1486mm, wheelbase 2700mm, and fuel tank capacity 55 liters.

What Does Anti-Lag System Mean?

Anti-lag system refers to the anti-lag ignition system. Here is more information about the anti-lag system: 1. The anti-lag system is an electronic device used in rally racing or drag racing, with the basic function of reducing turbo lag. 2. The working principle of the anti-lag system is to forcibly inject fuel into the cylinder without igniting it. After compression, the fuel is ignited when it's time to exhaust, allowing the exhaust gases to be expelled and maintaining the turbocharger's speed to reduce turbo lag. 3. The anti-lag system stops the ignition action when lifting off the throttle to shift gears, intentionally allowing the fuel-air mixture to enter the exhaust manifold after the exhaust valve opens. The manifold temperature is extremely high, causing the mixture to explode upon contact. The powerful explosion pressure pushes the turbine's exhaust blades, causing the compressor side blades in the turbocharger to rotate at high speed and continue boosting, ensuring boost pressure even when the vehicle is at low speed or shifting gears. 4. The main purpose of the anti-lag system is to maintain the normal operation of the turbocharger when the engine does not require power output but needs a large amount of air intake, especially when turbocharged race cars reduce power for cornering, ensuring a quick response when power output is needed.

What does XL on the tire mean?

Tire XL has the following specific meanings: 1. XL in the tire specifications refers to reinforced load (i.e., load index) tires. According to the national standard: XL or EL = reinforced tires (enhancing the tire's load-bearing and carrying capacity), usually used for large-load vehicles such as trucks, lorries, buses, and other engineering vehicles. 2. Extension: Generally, ordinary cars should not use tires with an aspect ratio greater than 75%, while luxury cars and high-performance sports cars are recommended to use tires with an aspect ratio less than 60%. The R on the tire is the abbreviation of the English word "radial," indicating that the tire has a radial structure.
