Timely four-wheel drive is generally prone to failure after several years. Here are the details: Working Principle of Timely Four-Wheel Drive: The timely four-wheel drive system only switches to four-wheel drive when necessary, while remaining in two-wheel drive under other conditions. The system automatically switches between two-wheel and four-wheel drive modes based on the vehicle's driving conditions, without requiring manual operation. Advantages: Compared to full-time four-wheel drive, the structure of timely four-wheel drive is much simpler, which not only effectively reduces costs but also helps lower the overall vehicle weight. Due to its unique structure, timely four-wheel drive is more suitable for vehicles with front transverse engine front-wheel drive platforms. This makes it possible for many SUVs or four-wheel drive sedans based on this platform to be equipped with a four-wheel drive system. The front-wheel drive platform is more conducive to expanding interior space, improving transmission efficiency, and reducing transmission system noise compared to the rear-wheel drive platform. These advantages are particularly important for small SUVs, especially those with smaller engine displacements.

What is the wading depth of the new Sagitar?

The wading depth of the new Sagitar is 310mm. Below is relevant information about the new Sagitar: 1. Wheel height: The exhaust pipe of the Magotan is 320mm from the ground, and the half-height of the wheel is 310mm. These two heights are basically at the same level. From this perspective, the safe wading height for the Magotan is around 300mm. Above this height, water may enter the exhaust pipe, but as long as you drive steadily, the vehicle will not stall. There is no need to accelerate heavily to pass through; you can confidently wade through. 2. Water entry points: The engine has three potential water entry points: the air filter, the oil dipstick hole, and the exhaust pipe. The first two are roughly at the same height as the upper edge of the tire, so as long as the water does not exceed the front wheels, it's not a concern. The exhaust pipe is lower, but even if it is underwater, as long as the engine is running, it continuously expels gas, preventing water from entering. The biggest risk with a submerged exhaust pipe is engine stalling. The moment the engine stalls, the negative pressure in the cylinder can draw water in.

What are the dimensions of the Lynk & Co 05?

The dimensions of the Lynk & Co 05 body are 4592*1879*1628mm, which are official data. The length of the Lynk & Co 05 refers to the distance between the two vertical lines perpendicular to the vehicle's longitudinal symmetry plane and touching the outermost protruding parts at the front and rear of the vehicle; the width refers to the distance between the planes parallel to the vehicle's longitudinal symmetry plane and touching the outermost rigid fixed protruding parts on both sides of the vehicle; the height refers to the distance between the highest point of the vehicle and the vehicle's supporting plane. The Lynk & Co 05 is equipped with a 2.0T turbocharged engine, with a maximum horsepower of 254 and a maximum torque of 350 Nm, paired with an automatic transmission (AT). There are national regulations regarding vehicle dimensions. According to the national standard "GB1589-89," the total width of a vehicle does not include the rearview mirrors. The limitation on vehicle width is to provide sufficient lateral clearance for overtaking between adjacent lanes. In other words, under national standards, the significance of vehicle width data lies in ensuring enough space during overtaking, preventing accidents due to excessive width or situations where road markings are narrower than the vehicle's width. Additionally, national regulations stipulate that the total width of a vehicle must not exceed 2.5m to meet the requirements of public road usage.

Does Replacing the Engine Affect the Car?

Replacing the engine does not affect the car as long as the installation is done correctly. Apart from the engine, other components such as the transmission, drive axle, steering mechanism, and braking system generally remain unchanged. However, the new engine requires a break-in period. According to relevant regulations, the vehicle owner must apply for a modification registration with the local vehicle management office within ten days after replacing the engine. The car engine is the device that provides power to the car, acting as the heart of the vehicle, determining its power, fuel efficiency, stability, and environmental performance. Depending on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid engines, among others.
