The reasons why the car air conditioner cannot be turned off are: 1. The air conditioner's switch button is damaged; 2. The air conditioner's thermostat is damaged; 3. The switch contacts are stuck; 4. There is a fault in the switch circuit; 5. Poor contact in the switch. The functions of the car air conditioner are: 1. Adjusting the interior temperature; 2. Humidity regulation; 3. Airflow regulation; 4. Air purification. The working principle of the car air conditioner is that the compressor sucks in the low-temperature and low-pressure refrigerant gas at the outlet of the evaporator, compresses it into high-temperature and high-pressure gas and discharges it from the compressor. The high-temperature and high-pressure superheated refrigerant gas enters the condenser, where it condenses into a liquid due to the reduction in pressure and temperature, releasing a large amount of heat.

What are the impacts of a leaking car exhaust pipe?

The impacts of a leaking car exhaust pipe include: 1. Affecting the car's power; 2. Increasing fuel consumption; 3. Exacerbating noise levels. The exhaust pipe is part of the engine's exhaust system, which mainly consists of the exhaust manifold, exhaust pipe, and muffler, typically including a three-way catalytic converter to control engine pollutant emissions. The exhaust pipe generally includes a front exhaust pipe and a rear exhaust pipe. The exhaust pipe is installed between the engine exhaust manifold and the muffler, providing a flexible connection for the entire exhaust system. The structure of the exhaust pipe is a double-layer corrugated tube covered with a steel wire mesh sleeve, with clamping rings at both ends. To enhance the muffling effect, the corrugated tube can be equipped with an expansion joint or mesh sleeve internally.

Should You Press the Clutch When Decelerating in a Manual Transmission Car?

When decelerating in a manual transmission car, you don't need to press the clutch. However, when braking during driving, each gear must maintain a speed above the minimum threshold; otherwise, you should press the clutch to prevent stalling. The function of the clutch: While driving, the driver can press or release the clutch pedal as needed to temporarily separate or gradually engage the engine and transmission, thereby cutting off or transferring the engine's power input to the transmission. Correct operation when braking: First press the brake, then the clutch. This is because, in the initial phase of braking, releasing the throttle allows the engine to provide braking force. If you press the clutch first, it disconnects the engine, relying solely on the friction of the brake pads for braking, which increases the braking distance.

What kind of accidents will disqualify a vehicle from the 6-year exemption policy?

In cases of traffic accidents resulting in casualties, the involved vehicle will not be eligible for the 6-year exemption policy. Vehicle inspection exemption cycle: For non-operational small and mini passenger vehicles (excluding vans) over 6 years but under 10 years old, the inspection cycle is relaxed from annual inspection to biennial inspection. This means private cars only need to undergo 2 on-site inspections within 10 years - in the 6th and 8th years respectively. For private cars over 10 years old, the original inspection cycle still applies: annual inspection for 10-15 year-old vehicles, and semi-annual inspection for vehicles over 15 years old. Scope of vehicle inspection exemption: Building upon the existing 6-year exemption for non-operational small passenger vehicles with 6 or fewer seats, the exemption scope has been further expanded to include 7-9 seat non-operational small and mini passenger vehicles (excluding vans) within 6 years.

What are the consequences of a faulty oil control valve?

Burning oil can cause the vehicle's oxygen sensor to deteriorate too quickly; burning oil can lead to increased fuel consumption, excessive exhaust emissions, unstable idle speed, heightened vehicle hazards, and increased financial burden. Burning oil can also result in adverse effects such as increased carbon deposits in the engine combustion chamber, loss of acceleration, sluggish speed, and insufficient power. Below is relevant information: 1. Engine oil: Engine oil, also known as engine lubricant, with a density of approximately 0.91×10³ (kg/m³), serves to lubricate and reduce friction in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. 2. Oil control valve: The oil control valve regulates and prevents excessive pressure in the engine lubrication system. The oil control valve consists of two main components: the valve body assembly and the actuator assembly (or actuator system), and is divided into four major series: single-seat control valves, double-seat control valves, sleeve control valves, and self-operated control valves.

What Causes the Sizzling Sound from the Steering Wheel?

The sizzling sound from the steering wheel may be due to abnormal noise from the steering gear or the steering linkage. The steering wheel is a wheel-shaped device used to control the direction of cars, ships, airplanes, etc. Its function is to convert the force applied by the driver on the edge of the steering wheel into torque, which is then transmitted to the steering shaft. It mainly consists of a frame, foam, and the corresponding installation clips or screw holes for the driver's airbag (DAB). The reasons for steering wheel vibration include: 1. Issues with the rubber bushings of the steering wheel transmission device; 2. Loose bolts fixing the steering wheel transmission device; 3. Problems with engine idle or steering gear; 4. Shock absorber failure; 5. Frame deformation; 6. Excessive meshing clearance of the drive gear; 7. Overheated brake discs or brake pads.
