What kind of engine oil should be used for turbocharged cars?

It is recommended to use fully synthetic engine oil with SN0W-40 or SN0W-30. More information on using engine oil for turbocharged engines is as follows: 1. The turbocharger activates when the engine speed reaches 3500 rpm and quickly increases to 6000 rpm. The higher the engine speed, the stronger the lubricating oil's resistance to shear must be. 2. Turbocharged engines have excellent performance and require higher standards for lubricating oil in terms of lubrication, sealing, heat dissipation, and rust prevention. 3. Engine oil should be added appropriately: Excessive oil addition will reduce the engine's output power, and the oil may enter the combustion chamber and participate in combustion, leading to high fuel consumption.

Reasons for Excessive Negative Pressure in the Crankcase

Crankcase negative pressure becomes excessive due to inadequate ventilation. More information about the crankcase is as follows: 1. Crankcase ventilation methods: natural ventilation and forced ventilation. To prevent excessive crankcase pressure, extend the service life of engine oil, reduce component wear and corrosion, and prevent engine oil leakage, crankcase ventilation must be implemented. 2. Modern gasoline engines often use forced crankcase ventilation, also known as the PCV system. The purposes of crankcase ventilation are as follows: 1. To prevent lubricating oil from deteriorating and fuel from diluting the oil, thereby reducing wear and corrosion of engine components. 2. To reduce pressure and temperature and prevent leakage: gases entering the crankcase increase the pressure and temperature inside, causing lubricating oil to leak from the crankshaft oil seal and gaskets. 3. To recover combustible gases and reduce pollution. By re-introducing gases that have entered the crankcase back into the cylinders for combustion, CH compounds are recycled, while also reducing atmospheric pollution.

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.
