What are the reasons for a car air conditioning compressor not working?

Reasons for a car air conditioning compressor not working: internal wear of the compressor or circuit system failure, it is recommended to promptly visit a 4S store for inspection and repair. More information about the air conditioning compressor is as follows: 1. The car air conditioning compressor is part of the car air conditioning refrigeration system, responsible for compressing and transporting refrigerant vapor. 2. Air conditioning compressors can be divided into the following two types based on their working principles: 1. Fixed displacement compressor: The exhaust volume increases proportionally with the increase in engine speed, controlled by collecting temperature signals from the evaporator outlet and the air conditioning system pressure. 2. Variable displacement compressor: The exhaust volume automatically adjusts the power output according to the set temperature, controlled by changes in pressure signals within the air conditioning pipeline.

What Are the Pass Standards for Vehicle Exhaust Emissions Testing?

National V exhaust emission testing data standards: CO, THC, NMHC, NOx, and PM are 1.00g/km, 0.100g/km, 0.068g/km, 0.060g/km, and 0.0045g/km respectively. The hazards of vehicle exhaust emissions are as follows: 1. Scientific analysis shows that vehicle exhaust contains hundreds of different compounds, including pollutants such as solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead, and sulfur oxides. A car emits three times its own weight in harmful exhaust gases each year. The British Society for Clean Air and Environmental Protection once published a research report stating that the number of people who die from air pollution in the UK each year is 10 times higher than those who die in traffic accidents. 2. While directly harming human health, exhaust emissions also have a profound impact on the environment. Sulfur dioxide in exhaust has a strong irritating odor and, at certain concentrations, can easily lead to "acid rain," causing soil and water acidification and affecting the growth of crops and forests. Over the past 100 years, the greenhouse effect has become a major scourge for humanity. Melting glaciers, rising sea levels, El Niño, and La Niña phenomena have all posed extremely severe challenges to human survival, with carbon dioxide being the main culprit behind the greenhouse effect.

What type of engine oil is used in the Magotan car?

The new Volkswagen Magotan uses SM grade or higher 5W-30 synthetic engine oil. Below are the details about this engine oil: 1. The selected engine oil must comply with the VW50200 standard, and high-quality unleaded gasoline meeting the GB17930 standard must be used. 2. If the consumer's budget allows, fully synthetic engine oil can be used. Compared to naturally aspirated engines, turbocharged engines operate under more complex conditions and have higher requirements for engine oil performance, making fully synthetic oil the best choice. 3. For brand selection, if longevity is a priority, Mobil engine oil can be chosen. 4. If strong cleaning capability is required, Shell engine oil is recommended. 5. For engine oil with strong oil film toughness, Castrol is suggested. For example, turbocharged engines are prone to carbon buildup at high speeds, so Shell fully synthetic oil with strong cleaning performance can be selected.

Why is there a hump in the middle of the back seat in many cars?

Car rear seat humps are primarily due to strength and structural requirements. The specific reasons for the rear seat hump are as follows: 1. Enhancing body structural strength. The hump in the middle of the rear seat acts like an additional longitudinal beam, increasing torsional rigidity to improve the vehicle's stability, while also strengthening the floor to prevent tearing during collisions. 2. Accommodating the driveshaft for rear-wheel and four-wheel drive systems. Most cars are rear-wheel drive, with the engine positioned at the front, requiring a long driveshaft to transmit power to the rear wheels. 3. Raising the exhaust pipe's ground clearance. The exhaust pipe is connected to the engine and experiences significant vertical movement while driving; if placed too low, it is prone to scraping against the ground.

How Often Should the Three-Way Catalytic Converter Be Cleaned?

Car three-way catalytic converters should be cleaned every 10,000 kilometers. The cleaning method for the three-way catalytic converter is as follows: 1. Place the removed three-way catalytic converter upright in a plastic bucket, shake the three-way catalytic cleaner evenly, put it into the pot lock of the high-pressure spray gun, connect the air pipe, and spray evenly on the three-way catalytic converter grid, repeatedly rotating the three-way catalytic converter for cleaning. 2. After spraying for 6 seconds, pause for 3 minutes to allow the cleaning solution to penetrate deeply into the carbon deposits, quickly foam, and dissolve the carbon deposits into mud that flows out. 3. The slow-release agent in the cleaning solution forms a protective film on the metal surface, and spraying on the rhodium, platinum, palladium, and other precious metals at the grid base can effectively protect them.

What Causes High Car Thermometer Readings?

Most cases of rising car temperatures are caused by water pipe leakage or insufficient coolant. Here are relevant explanations about high engine coolant temperature: 1. Insufficient Coolant: Prolonged water circulation during engine operation can gradually deplete the cooling system's coolant, resulting in radiator fluid shortage. If the owner fails to promptly inspect and replenish the coolant, this can easily lead to excessively high engine temperatures. 2. Cooling Fan Malfunction: Damaged cooling fans or short-circuited wiring may prevent proper fan operation or cause slow fan rotation. This inhibits heat dissipation from the engine, naturally leading to increased coolant temperatures.
