Chery Arrizo 5 air conditioning system may fail to cool due to the following reasons: 1. Compressor capacitor damage or malfunction: This can cause the compressor to stop working. 2. Room temperature sensor resistance value change: This leads to the outdoor unit not working (the symptom is similar to the air conditioner shutting down after reaching the set temperature). 3. Damage to the indoor or outdoor fan (often due to capacitor failure): Failure of the outdoor fan manifests as excessively high exhaust temperature or high-pressure protection, while failure of the indoor fan results in frost formation on the indoor unit, continuous operation of the outdoor unit, and condensation on the indoor unit. 4. Other factors: Issues such as low power supply voltage reducing the electromagnetic clutch's pull force, or oil contamination between the clutch pressure plate and pulley, can cause a "slipping" phenomenon similar to a loose drive belt. If the evaporator surface frosts over or the blower motor speed decreases, it can also lead to insufficient cooling. Additionally, compressor wear or valve leakage can result in inadequate cooling performance. 5. Refrigeration system issues: Common faults like insufficient cooling or reduced cooling efficiency are often caused by refrigeration system sealing problems. Modern automotive refrigerants have strong permeability, requiring high system sealing standards. Even minor leaks in refrigeration pipelines or valves can cause insufficient cooling.

Is the Mercedes-Benz C260 a B-segment or C-segment car?

The Mercedes-Benz C260 belongs to the B-segment. As one of the representatives of luxury B-segment cars, the Mercedes-Benz C260 is impressive in both appearance and performance. Although it may not have as strong a sporty feel as the BMW 3 Series, its luxurious temperament undoubtedly makes it a dominant presence in the B-segment market. Cars generally come in standard, low, mid, and high trim levels, which refer to: 1. Low trim: Usually a simplified version, lacking features like leather seats, power windows, and many electronic controls. 2. Standard trim: Includes basic electric controls such as power windows, power steering, and air conditioning. 3. Mid trim: Slightly more advanced than the standard trim, including all standard features plus additional elements like airbags, a sunroof, leather seats, power seats, and seat heating. 4. High trim: More advanced than all the above configurations, often considered the flagship version of the model.

What is the penalty for driving at 85 in an 80 speed limit zone?

On a road with a speed limit of 80 km/h, driving at 85 km/h is considered speeding and can be captured by traffic cameras. Since the speed does not exceed 10% of the limit, there will be no points deducted or fines issued. However, a warning will be given for speeds exceeding the limit by less than 10%. For your own safety, avoid speeding. Additional information: Below are the penalties for exceeding the speed limit by more than 10%: 1. Exceeding the speed limit by 10% to 20%: A fine will be issued, and 3 points will be deducted. 2. Exceeding the speed limit by 20% to 50%: A fine will be issued, and 6 points will be deducted. 3. Exceeding the speed limit by more than 50%: 12 points will be deducted directly as per regulations. Note: When driving on highways, avoid fatigue driving. Be responsible for your own safety and the safety of others. Ensure you are well-rested and have sufficient sleep before driving on highways to prevent any mishaps.

What is the 10-Year Vehicle Inspection Exemption Policy?

There is no 10-year inspection exemption policy for vehicles. Instead, new vehicles within the first 6 years can be exempted from inspection twice. Below is a detailed introduction to the inspection exemption policy: 1. Regulations: New vehicles within the first 6 years can be exempted from inspection twice, but inspections are required at the 6th and 8th years at a testing facility. For private vehicles over 10 years old, the original inspection cycle still applies: annual inspections for vehicles aged 10 to 15 years, and semi-annual inspections for vehicles over 15 years old. The new regulation includes 7 to 9-seater non-operational small and micro passenger vehicles (excluding minivans) within the 6-year exemption scope. For non-operational small and micro passenger vehicles (excluding minivans) over 6 but under 10 years old, the inspection frequency is adjusted from annual to biennial. 2. Relevant Information: Vehicle safety technical inspections are conducted by authorized inspection agencies. These agencies must perform inspections according to national standards and bear legal responsibility for the results. If the registered details on the vehicle’s license do not match the actual condition of the vehicle, or if the mandatory third-party liability insurance certificate is not provided as required, the inspection will not be passed.

What are the reasons for the lack of power in Weichai engines when climbing slopes?

The reasons for the lack of power in Weichai engines when climbing slopes are as follows: 1. Fuel supply system failure: Fuel leakage or minor blockage in the fuel supply system, poor atomization or insufficient fuel injection in some cylinders, incorrect fuel injection timing. 2. Insufficient compression pressure: Intake and exhaust valves not opening properly, blocked air pipes, improper valve clearance or leaking cylinder gaskets, wear, sticking, or breakage of cylinder liners and piston rings, insufficient vacuum. 3. Other reasons: Engine overheating, deformation of transmission components causing torque issues. The characteristics of Weichai engines are as follows: 1. Feature one: Base-mounted structure, greatly facilitating maintenance and reducing workload. 2. Feature two: Crankshaft made of high-strength ductile iron, treated with nitriding. 3. Feature three: Wet cylinder liners made of boron alloy cast iron, with inner surfaces honed with a plateau cross-hatch pattern, offering high strength, low wear, and long service life. 4. Feature four: Pistons equipped with three compression rings and one oil ring, the first being a chrome-plated barrel face ring for good break-in performance. 5. Feature five: P-series fuel injection pumps and low-inertia fuel injectors produced with imported technology.
