How many cylinders does the BMW 325 engine have?

The BMW 325 is equipped with a 4-cylinder engine, model B48B20B, with a maximum power output of 135 kW and a maximum torque of 300 Nm. The engine of the BMW 325 is assembled in China using German technology and is produced at the Shenyang Tiexi factory. For daily maintenance of the BMW 325 engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment in the intake and exhaust systems and usage conditions. For diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, ensuring the standard meets or exceeds the manufacturer's requirements. Regularly change the engine oil and filter. The quality of any lubricating oil will degrade over time. After a certain mileage, performance deteriorates, leading to various engine issues. To prevent malfunctions, change the oil periodically based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances accumulate in the filter. If the filter becomes clogged and oil cannot pass through, the filter may rupture or the safety valve may open, allowing oil to bypass the filter and carry contaminants back to the lubrication points, accelerating engine wear and increasing internal contamination. 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. These mix with metal particles from component wear, forming sludge. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Periodically use a radiator cleaner to flush the radiator. Removing rust and scale deposits not only ensures proper engine operation but also extends the overall lifespan of the radiator and engine.

What Are the Car Tire Maintenance Items?

There are 6 items for car tire maintenance: 1. Tire rotation - It is recommended to rotate the tire positions every 10,000 kilometers to equalize tire fatigue, prevent uneven wear, and extend tire service life; 2. Four-wheel alignment - It is recommended to check every 30,000 kilometers to reduce abnormal tire wear caused by changes in four-wheel alignment parameters; 3. Tire pressure inspection - Check at least once a month. If the tire pressure decreases too quickly, please visit a local tire shop for inspection to avoid greater damage to the tires; 4. Tire dynamic balance inspection - This is to prevent steering wobble when the car speed increases. If the steering wheel wobbles when the car speed exceeds 70 km/h, a tire dynamic balance inspection should be performed promptly; 5. Tire tread depth inspection - When the tire wears down to the wear indicator mark, the tire must be replaced. Using tires beyond the wear indicator mark is very dangerous when driving on wet surfaces because the drainage performance is greatly reduced, which will seriously affect wet surface grip; 6. Tires are rubber products and will age or crack over time. If aging or cracking is found during inspection, they should be replaced promptly.

How to Replace the Front Fog Light on a Changan Eado?

When opening the fog light cover, pry from the inside to the outside, applying slight force to release each clip one by one. To prevent scratching the car paint, you can wrap a thin cloth around the tool. To replace the fog light, simply unscrew the three fixing screws. Below is some relevant information about fog lights: 1. In adverse weather conditions such as fog, snow, and heavy rain, or when driving in smoke-filled environments, front fog lights must be used to illuminate the road ahead and ensure driving safety. In recent years, fog lights have often been integrated into the design of the front bumper. 2. The purpose of fog lights is to make the vehicle visible to others in conditions of reduced visibility due to weather, such as fog or rain. Therefore, the light source of fog lights needs to have strong penetration. Most vehicles use halogen fog lights, while xenon fog lights are considered a more advanced option.

What Are the Reasons for Windshield Washer Not Spraying Water?

When a car's windshield washer fails to spray water, it could be due to clogged spray nozzles or a malfunctioning washer motor. Below are detailed explanations: Clogged Spray Nozzles: Use a sewing needle, pin, or very thin wire to gently unclog the nozzles. Then, spray out the remaining windshield washer fluid and use an air gun to blow air through the clogged nozzles. Malfunctioning Washer Motor: Inspect the motor and its wiring. Have someone operate the washer button inside the car while another person opens the engine compartment to listen for any sound from the washer motor. If the sound is very weak, the motor is likely faulty. If there is no sound and the wiring checks out fine, the issue is probably with the motor itself, and it will need to be replaced.

What do the letters on car tires represent in terms of speed?

Tire letters such as J represent 100km/h, K represents 110km/h, etc. Here's an introduction to tire-related information: Introduction to tire letter grades: The letter Y refers to the tire speed rating, indicating the maximum speed the tire can withstand under specified conditions. Different tires have different letters representing their speed ratings engraved on the sidewalls, with the letter range spanning from A to Z. Tire replacement standards: Rubber has a certain service life. Under normal circumstances, car tires have a service life of about 3-5 years because tires are exposed to wind, sun, and rain for long periods, causing the rubber to gradually age. Aged tires have reduced strength, so when tires reach their service life, they should be replaced promptly.
