Tire bulges mainly occur due to the following reasons: 1. Excessive tire pressure during use: This reduces the tire's contact area with the ground, leading to premature wear. During operation, rolling acceleration or poor heat dissipation can cause the tread temperature to rise, resulting in bulges. 2. Tire quality issues: During manufacturing, if the drying process of the cord is insufficient before rubber coating, or if the rubber compound contains excessive moisture. 3. Problems with bead wire sealing: The rubber at the bead wire area may age and delaminate due to high temperatures or improper rubber compound formulation. Additionally, when using modified rims, irregular deformation during driving can cause friction, generating high heat at the bead area and leading to bulges.

If the electric fan is not functioning properly or fails to operate, the control module should be inspected. Electric fan control methods: Unlike engine-driven fans, automotive electric fans need to adjust their working state based on coolant temperature. Some are controlled by the vehicle's ECU, while others operate via a thermistor switch. Different cars may have varying electric fan control methods. Structural components: Generally, an electric fan assembly includes the electric fan itself, mounting brackets, temperature sensors, thermal switches, relays, wiring harnesses, etc. If the electric fan fails to operate, troubleshooting can be conducted based on these components.

What is the Tang DM's four-wheel drive system?

BYD Tang DM is the plug-in hybrid four-wheel-drive version of the BYD Tang. Definition of four-wheel-drive vehicles: Four-wheel drive is typically used only on muddy, icy, snowy, or rough road conditions. It operates at lower speeds with higher fuel consumption but provides better stability without side skidding during emergency braking. When only rear-wheel drive is engaged, the load is smaller, resulting in reduced driving force, similar to front-wheel drive and two-wheel drive. Function of four-wheel drive: Four-wheel drive means that both the front and rear wheels of the vehicle have driving power. The engine's output torque can be distributed in varying proportions to all wheels depending on road conditions to enhance the vehicle's driving capability. It is generally denoted by 4X4 or 4WD. If you see these markings on a vehicle, it indicates that the vehicle is equipped with four-wheel-drive functionality.
