What engine does the Lifan 820 car have?

Lifan 820 engine is a domestically produced engine, manufactured by Lifan Engine Company. The 1.8L version of the Lifan 820 has an engine model number LFB479Q, with a maximum power of 98kW and a maximum torque of 168 Nm. The 2.4L version has an engine model number LF489Q, with a maximum power of 123kW and a maximum torque of 226 Nm. For daily maintenance of the Lifan 820 engine, 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 equipment of the intake and exhaust systems 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 specified 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 based on usage conditions and keep the oil level 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 contaminants back to the lubrication area, accelerating engine wear and increasing internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures normal engine operation but also extends the overall lifespan of the radiator and engine.

What to Do When the Car Door Won't Open with a Mechanical Key?

Solutions for when the car door won't open with a mechanical key: 1. Inject some engine oil into the lock cylinder to lubricate it and then try to open it; 2. Check if the car is in anti-theft lock mode, as the mechanical key cannot open the door in this state—it needs to be deactivated first; 3. Replace the lock cylinder; 4. Use the remote key to open the door; 5. Contact a professional for inspection and repair. It's important to note that in most cars, the central locking mechanism uses a mechanical latch to secure the door. If the door lock isn't engaged, the door can be opened using the exterior door handle or the interior door handle.

Why is the car shaking violently?

Further diagnosis is required to determine whether the severe shaking occurs when the engine is idling after startup or when the vehicle is in motion, as different conditions require different inspection approaches. Possible causes of severe car shaking include: 1. Ignition system issues: Faults in the car's ignition system can lead to poor ignition performance or weak spark plug firing, resulting in unstable idling. 2. Worn or loose engine mounts: Engine mounts are rubber blocks placed between the engine and the frame. 3. Carbon buildup problems: Carbon deposits can accumulate in the cylinders, throttle body, spark plugs, and intake system.
