The B48B20C engine is a domestically produced engine used in the BMW 3 Series, manufactured at BMW Brilliance's Tiexi factory. The BMW 3 Series is equipped with the B48B20C engine, which has a maximum power output of 135kW, a maximum torque of 290 Nm, and a maximum horsepower of 180. Here are some maintenance methods for the B48B20C engine in daily use: Use lubricating oil of appropriate quality grade. For gasoline engines, choose SD--SF grade gasoline engine oil based on the additional devices in the intake and exhaust systems and usage conditions; for diesel engines, select CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, the performance deteriorates, leading to various engine problems. To avoid malfunctions, change the oil regularly according to usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes 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 and carry contaminants back to the lubrication areas, 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, mixing with metal particles from component wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, 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 the engine operates normally but also extends the overall lifespan of the radiator and engine.

Can You Shift Directly from Fourth Gear to First Gear in a Manual Transmission?

Manual transmissions cannot shift directly from fourth gear to first gear. The specific reasons are as follows: 1. Damage: Based on the actual vehicle speed, you should select the appropriate gear. Shifting directly from a high gear to a low gear can harm the transmission and reduce driving comfort. 2. Difficulty in Operation: It is generally difficult for most people to perform. If you press the accelerator to 6903 rpm in first gear, then press the clutch, the engine speed will drop to 2000 rpm. At this point, shifting directly to fourth gear is completely fine—this is the simple operation of shifting from first to fourth gear. However, if you are driving in fourth gear at 2000 rpm, pressing the clutch while simultaneously pressing the accelerator to raise the engine speed to 7000 rpm and then shifting to first gear is also possible. The issue is that such a rapid sequence is difficult for most people to execute—this is known as "rev-matching downshift."

The Quattroporte measures 5262*1948*1481 (mm) in length, width, and height, with a wheelbase of 3171 mm, front track of 1634 mm, and rear track of 1647 mm. (2) Front bumper: The Quattroporte's front bumper is divided below, while the Ghibli's front bumper is integrated. (3) Engine hood: The Quattroporte's engine hood extends to the edge of the headlights, while the Ghibli's engine hood has a certain distance from the headlights. Additionally, the Quattroporte's engine hood is recessed in the middle, while the Ghibli's is raised, making the Ghibli appear more aggressive. (4) Headlights: The Quattroporte's headlights have a yellow element, while the Ghibli's do not, but the Ghibli's headlights appear more high-tech. (5) Taillights: The white part of the Quattroporte's taillights extends to the corner edge, while the Ghibli's white part is cut off before reaching the corner. The Quattroporte's reflector above the exhaust pipes is more recessed. 2. Configuration differences between the Ghibli and Quattroporte: The Quattroporte comes standard with: adaptive suspension, power trunk, hands-free trunk access, keyless entry for all doors (Ghibli only for front doors), power-adjustable steering wheel (Ghibli only manual, power is optional), steering wheel memory, heated front and rear seats, Harman Kardon sound system, 10-speaker setup (Ghibli has 8), heated washer nozzles, rear independent air conditioning, power side window sunshades, etc. Some of these standard features on the Quattroporte are optional or not available on the Ghibli.

Does Parking a Car at an Angle Affect the Vehicle?

Frame deformation, suspension system damage, and tire wear are all hazards caused by parking a car at an angle. When parking a vehicle for an extended period, it is essential to choose an appropriate parking spot to ensure all four wheels are on the same plane. The specific effects of parking a car at an angle include: Frame deformation: The car body has numerous openings for doors and hoods, requiring high precision in manufacturing. Parking at an angle causes uneven force distribution, leading to deformation over time. Prolonged exposure can result in irreversible frame deformation, severely affecting the normal operation of doors and making the body frame the most challenging symptom of aging to restore. Suspension system damage: The car's suspension system, including shock absorbers, springs, and anti-roll bars, is affected when parked on an inclined surface. While the shock absorbers may not be engaged, the springs and anti-roll bars remain under tension. Long-term angled parking causes uneven fatigue in the springs on one side, reducing their performance and lifespan. Tire wear: Tires bear the entire weight of the car. Parking at an angle leads to uneven force distribution, causing deformation or uneven wear. Over time, this can result in significant tire damage.

What Causes Engine Shaking When Starting a Car in Cold Weather?

Engine shaking during cold starts occurs because the engine's water temperature is too low. To quickly raise the engine to its ideal operating temperature, the fuel supply system automatically enriches the air-fuel mixture, causing the engine to run more intensely and resulting in unstable operation and significant idle shaking. Below is more information about cold weather starts: 1. Preheating is the first and most crucial step when driving in cold weather. Due to low winter temperatures, lubricating oil becomes much thicker and less fluid compared to other seasons. 2. After starting the engine, let it idle at around 1000 RPM to warm up before driving. Avoid pressing the accelerator sharply or allowing the engine speed to become too high. There's no need to wait for the engine temperature to reach the optimal level before driving—starting is safe as soon as the temperature gauge needle begins to rise.
