National VI vehicles can use SN-grade engine oil. Suitable engine oil: Castrol 5W-30 can be used as the original equipment manufacturer (OEM) oil for luxury brands such as BMW, Audi, and Jaguar. Advantages of SN-grade engine oil: The addition of certain metal elements in the oil can improve its low-temperature resistance and anti-corrosion properties, while also reducing direct metal-to-metal contact, thereby minimizing friction losses. Castrol Edge is suitable for most luxury cars, mid-to-large-sized vehicles, SUVs, turbocharged models, and high-performance sports cars. Essentially, current engine oils like Shell prioritize economy and environmental friendliness, Castrol focuses on low-temperature and anti-corrosion performance, while Mobil emphasizes anti-wear properties.

How Many Cylinders Does the Lynk & Co 01 Engine Have?

The Lynk & Co 01 is equipped with a four-cylinder engine, delivering a maximum horsepower of 190Ps, a maximum power output of 140kW, and a peak torque of 300N·m. Below is an introduction to the engine's features: 1. The four-cylinder engine can be considered the most mature and stable engine type. When factoring in fuel consumption and other considerations, the four-cylinder engine stands out as the most balanced in terms of overall performance. While engines like V8 and V12 offer robust power, they come with significantly higher fuel consumption and severe exhaust pollution. 2. Under the pressure of environmental policies and influenced by global trends, an increasing number of automakers are shifting toward smaller displacement engines. To achieve this, many manufacturers have begun adopting three-cylinder engines. However, due to inherent design limitations, three-cylinder engines may exhibit vibration issues after prolonged use.

Can You Drive with a Cracked Windshield?

If there is a crack in the windshield, it is generally unsafe to continue driving for safety reasons. However, if you must drive, do so at a slow speed to prevent the tempered glass from shattering due to vibration and causing injury. If the windshield is made of laminated glass (not tempered), even if it shatters, the pieces will not fall and cause harm. Below is some related information about cracked windshields: 1. A windshield is made by bonding a transparent, adhesive plastic film between two or three layers of glass, combining the toughness of plastic with the hardness of glass to enhance the glass's resistance to breaking. 2. Tempered glass is produced by quenching ordinary glass to create internal stresses, thereby increasing its strength. When impacted and shattered, tempered glass breaks into small, blunt-edged fragments, reducing the risk of injury to passengers.

What is the symbol for the external air circulation in a car's air conditioning?

The internal circulation symbol is a circular arrow inside a car graphic, while the external circulation symbol is an arrow entering the car from outside. Below is an introduction related to external and internal circulation: 1. Using external circulation allows you to breathe fresh air from outside the car. When driving at high speeds for long periods, the air inside the car can become stale and uncomfortable. If you cannot open the windows, you should use external circulation to bring in fresh air. 2. If the warm air in winter feels too hot, you can turn off the fan and activate external circulation. This maintains the interior temperature while allowing fresh air to enter, making you feel more comfortable. 3. The internal circulation in a car refers to the air inside the car being heated or cooled and then recirculated within the vehicle. External circulation refers to air from outside the car being heated or cooled before being sent inside, facilitating gas exchange between the interior and exterior.
