Does Lynk & Co Use Volvo Engines?

Lynk & Co is equipped with Volvo engines, which are produced in Taizhou and Zhangjiakou, China. The engine model of Lynk & Co is JLH-4G20TDC, with a maximum horsepower of 254ps, a maximum power of 187kw, and a maximum torque of 350nm. For daily maintenance of Lynk & Co engines, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust system and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to mechanical load, with the selection standard not lower than the manufacturer's requirements; Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, causing various problems for the engine. To avoid failures, change the oil regularly according to usage conditions and keep the oil volume moderate; When oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing oil to bypass through the bypass valve, bringing dirt back to the lubrication area, accelerating engine wear and increasing internal pollution; Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acid, moisture, sulfur, and nitrogen oxides in the combustion chamber enter the crankcase through the gap between the piston ring and cylinder wall, mixing with metal powder from part wear to form sludge. When the amount is small, it suspends in the oil; when large, it precipitates from the oil, clogging the filter and oil holes, making engine lubrication difficult and causing wear; Regularly use radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine works properly but also extends the overall lifespan of the radiator and engine.

Heavy-duty and medium-duty trucks are mainly trucks, such as the large trucks commonly seen on the road carrying construction waste, which belong to heavy-duty trucks. Large, heavy, and medium-sized special-purpose vehicles refer to vehicles equipped with special equipment or tools, such as water sprinklers, concrete mixers, fire trucks, etc. Other permitted vehicle types include C1 (small cars), C2 (small automatic transmission cars), C3 (low-speed trucks), C4 (three-wheeled cars), and M (wheeled self-propelled machinery), which are the same as those permitted by a B1 license. B2 Driver's License Application Requirements: Applicants must be between 21 and 50 years old; height must be at least 155 cm; both eyes must have a naked vision of at least 5.0; must be able to distinguish the direction of sound from a tuning fork at 50 cm with each ear to ensure correct judgment during actual driving; B2 driver's license can only be obtained within the prefecture-level city of the applicant's household registration and cannot be applied for with a temporary residence permit.

What are the techniques for troubleshooting abnormal noises inside the car?

Techniques for troubleshooting abnormal noises inside the car involve identifying and addressing the causes one by one. The reasons for abnormal noises after the car is turned off are as follows: 1. Cooling sound of the three-way catalytic converter: The normal operating temperature of the three-way catalytic converter is 400-800°C. After the car is turned off, its operation gradually stops, and the temperature decreases, causing the internal metal components to expand and contract with heat, resulting in abnormal noises. 2. Cooling sound of the exhaust pipe: Generally, during cold idling, the exhaust pipe can reach a temperature of over 200°C. When the car is under high load or there is a mixture of gases burning in the exhaust pipe, the temperature can be even higher. Therefore, the exhaust pipe also expands and contracts with heat, producing abnormal noises, often originating from the front end of the exhaust pipe and the flexible connection. 3. Cooling sound of the turbocharger: Under normal conditions, the temperature of the exhaust gases can reach 600-700°C, accelerating the friction-generated heat from the turbocharger's rapid rotation. After the car is turned off, the heat expansion and contraction are also quite noticeable, leading to abnormal noises.

What Causes Mold in a Car?

Mold in a car is caused by prolonged lack of ventilation or excessively humid environments, leading to the growth of mold. The interior components of the car are particularly prone to mold. Placing activated bamboo charcoal in the car can help absorb moisture and harmful substances, thereby regulating the humidity inside the vehicle. Below are some cleaning methods for the interior: 1. Seats, carpets, door panels, etc.: These can be wiped down or vacuumed for initial surface cleaning. 2. Leather interiors: It is best to use neutral or alkaline cleaners for cleaning to avoid damaging the leather. Allow them to air dry naturally, or you can turn on the car's heating mode to speed up the drying process.
