Do BMW Spark Plugs Need to Be Replaced Every 20,000 Kilometers?

BMW vehicles require spark plug replacement after driving 20,000 kilometers. Spark plugs are crucial components in a gasoline engine's ignition system. They introduce high-voltage electricity into the combustion chamber, creating a spark across the electrode gap to ignite the air-fuel mixture in the cylinder. Spark plug replacement procedure: Open the hood, remove the engine's plastic cover, detach the high-voltage ignition wires while marking each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. During removal, check for external debris like leaves or dust and ensure thorough cleaning. Insert new spark plugs into the holes, hand-tighten them for several turns before using the socket wrench. Reinstall the high-voltage ignition wires in the correct firing order and secure the cover plate.

What is the normal tire pressure for a Volkswagen Polo?

The recommended tire pressure for a Volkswagen Polo is 2.3 bar for the front wheels and 2.5 bar for the rear wheels. Owners can check the tire pressure by referring to the label on the outside of the B-pillar on the driver's side. Tire pressure can fluctuate depending on specific conditions. In summer or winter, due to the principle of thermal expansion and contraction, tire pressure increases in high temperatures and decreases in low temperatures. Therefore, summer tire pressure should be lower than winter tire pressure. Generally, it is recommended to keep summer tire pressure at the lower limit of the standard range, while winter tire pressure should be adjusted slightly higher by about 0.2 bar above the standard pressure. Hazards of overinflated tires: Reduced friction and adhesion of the tires, affecting braking performance; Causes steering wheel vibration and misalignment, reducing driving comfort; Accelerates wear on the central tread of the tire, shortening its lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overstretches the tire cords, reducing elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance, making it easier for sharp objects like nails or glass to penetrate the tire, leading to internal cracks or blowouts. Hazards of underinflated tires: Increases friction with the road surface, raising fuel consumption; Makes the steering wheel heavy and prone to misalignment, compromising driving safety; Increases movement of tire components, causing abnormal heat due to excessive rolling; Reduces the functionality of cords and rubber, leading to delamination or cord breakage, and excessive friction with the rim, causing damage to the bead area and abnormal wear; Multiplies friction with the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in blowouts; Increases tire deformation, causing cracks on the sidewalls and excessive heat from flexing, accelerating rubber aging, cord fatigue, and breakage, while also enlarging the tire's contact area and speeding up shoulder wear.

How Many Turns Can the Steering Wheel Make?

Here is an introduction to the steering wheel: 1. The steering wheel of a car can usually make 2 turns: some can make 1.5 turns. 2. Steering wheels are divided into power-assisted and non-power-assisted types: newer power-assisted vehicles can make 1.5 turns, while older non-power-assisted vehicles can make 2 turns. 3. One full turn of the steering wheel equals 360°: half a turn equals 90°. You can think of the steering wheel as a clock, with the correct hand position being the left hand at the 9 o'clock position and the right hand at the 3 o'clock position. If you want to turn 45°, position the steering wheel between the 12 o'clock and 3 o'clock directions.

Is it allowed to make a U-turn at an intersection where left turns are prohibited?

U-turns are not allowed at intersections where left turns are prohibited. Here are the detailed explanations: 1. U-turns are not permitted at locations with no U-turn or no left-turn signs and markings, as well as at railway crossings, crosswalks, bridges, sharp curves, steep slopes, tunnels, or sections of road prone to danger. 2. According to Article 90 of the "Road Traffic Safety Law of the People's Republic of China": Drivers of motor vehicles who violate the laws and regulations on road traffic safety regarding road traffic regulations shall be given a warning or fined not less than 20 yuan but not more than 200 yuan. In cases otherwise stipulated by this Law, penalties shall be imposed accordingly.

What transmission does the Geely Vision use?

Geely Vision is equipped with a 1.5L inline 4-cylinder naturally aspirated engine, paired with either a 5-speed manual transmission, 4-speed automatic manual transmission, or CVT continuously variable transmission. Transmission: A device that changes speed ratio and direction of motion, used in automobiles, tractors, ships, machine tools, and various machines to alter torque, speed, and motion direction transmitted from the driving shaft to the driven shaft under different working conditions. Gear transmission systems generally consist of a housing and several gear pairs. Geely Vision Powertrain: The Geely Vision is powered by a 1.5L naturally aspirated engine with a maximum power output of 109 horsepower and peak torque of 142Nm. It utilizes multi-point fuel injection technology, reaching maximum power at 6000 rpm and peak torque at 4400 rpm.
