Engine power reduction can be caused by: 1. Excessive carbon buildup in the engine, leading to insufficient air intake and affecting power output; 2. Blocked air intake system; 3. Fuel supply system obstruction; 4. Reduced spark plug efficiency; 5. Overheating coolant temperature; 6. Engine knocking in cylinders; 7. Excessive engine oil temperature. Engine maintenance methods: 1. Use qualified engine oil; 2. Use approved coolant; 3. Regularly clean radiator scale; 4. Periodically remove engine carbon deposits; 5. Replace air filter, oil filter, and fuel filter on schedule; 6. Check spark plugs for damage.

What are the steps to adjust the electric seats in the Verano?

Verano electric seat adjustment method is as follows: 1. Front and rear adjustment of the driver's seat: Push the control button forward or backward to move the seat to the desired position. Release the button to lock the seat in place. 2. Height adjustment of the driver's seat: Move the front or rear part of the control button up or down to adjust the height of the corresponding part of the seat. Additional information: 1. The electric seat system generally consists of a bidirectional motor, transmission device, and seat adjuster. Most motors are compact, high-power permanent magnet types, typically controlled by a switch located on the left side panel or left door armrest. The switch allows the motor to move in different directions. 2. When the switch is activated, the motor's power is transmitted through gears and drive shafts to rotate the flexible shaft, which then drives the seat adjuster. When the adjuster reaches the end of its travel, the flexible shaft stops rotating. If the motor continues to run, the power is absorbed by a rubber coupling to prevent motor overload damage in case the seat gets stuck.

What Does the Exclamation Mark on the Steering Wheel Mean?

The exclamation mark on the steering wheel indicates the Electronic Power Steering (EPS) warning light, which should disappear immediately after the engine starts. The Electric Power Steering (EPS) system is a power steering system that directly relies on an electric motor to provide auxiliary torque. Compared to the traditional Hydraulic Power Steering (HPS) system, the EPS system offers numerous advantages. The EPS system mainly consists of a torque sensor, vehicle speed sensor, electric motor, reduction mechanism, and Electronic Control Unit (ECU). The Electric Power Steering system was developed based on the traditional mechanical steering system. It utilizes the power generated by an electric motor to assist the driver in steering operations. The system primarily comprises three major components: signal sensing devices (including torque sensor, angle sensor, and vehicle speed sensor), steering assist mechanism (electric motor, clutch, and reduction transmission mechanism), and electronic control device. The electric motor operates only when steering assistance is needed. When the driver turns the steering wheel, the torque and angle sensors generate corresponding voltage signals based on the input torque and steering angle. The vehicle speed sensor detects the speed signal, and the control unit issues commands to control the motor operation based on the voltage and speed signals, thereby providing the required steering assistance.

What is the Difference Between Glazing and Crystal Coating?

The differences between glazing and crystal coating are as follows: 1. Different Definitions: The essence of glazing is similar to waxing. The "glaze" is extracted from petroleum and mixed with auxiliary materials. After cleaning the car surface, the "glaze" is applied through vibration, allowing it to fully penetrate the paint. Crystal coating involves using inorganic substances like silicon dioxide, which forms a strong crystalline barrier on the surface through molecular polymerization. This barrier resists UV rays, oil, has low surface energy, and is hydrophobic, thus protecting the paint. 2. Different Functions: Glazing blocks UV rays, prevents oxidation, resists high temperatures and acid rain, reduces minor scratches, enhances the gloss and hardness of the original paint, extends the paint's lifespan, and slows down browning. Crystal coating is currently the most advanced car paint protection solution, offering advantages such as corrosion resistance, scratch prevention, no cracking, and easy cleaning. It protects the vehicle from daily minor scratches. Even when external forces exceed the elastic protection range of the crystal, it usually only leaves scratches on the crystal layer without damaging the paint. 3. Different Durability: Glazing lasts relatively shorter than crystal coating, typically 6 to 8 months, providing substantial protection to the paint and making the car's surface smooth and soft. However, its protection duration is shorter than crystal coating, and its hardness is inferior. Crystal coating is more durable and stable, lasting 1-2 years, offering genuine paint protection. However, crystal coating is more expensive, takes about 2 days to apply, and requires higher technical skills from the technician.
