What is the function of the metal baffle in the car experiment?

The initial baffle provides an initial velocity, while the final baffle prevents damage. Here are some precautions regarding car driving: Cold car warm-up: Proper warm-up helps the engine oil form an 'oil film' between engine components, thereby reducing component wear. Timely gear shifting: When driving a manual transmission vehicle during the break-in period, shift gears promptly and appropriately, avoiding incorrect behaviors such as high gear with low RPM or low gear with high RPM, and do not use a single gear for an extended period. Timely maintenance: Simply follow the manufacturer's recommendations in the vehicle manual, and after reaching a certain mileage or time, promptly inspect and maintain the vehicle, including changing the engine oil and oil filter, and conduct a comprehensive inspection of the chassis system. Avoid emergency braking: Emergency braking not only impacts the braking system during the break-in period but also increases the shock load on the vehicle's chassis and engine.

Is it one or two annual inspections for cars after 15 years?

For cars after 15 years, it requires two annual inspections. Here is extended information about annual inspections: New regulations: According to the 2020 regulations, vehicles within 10 years require an inspection every two years. In the motor vehicle inspection reform implemented on November 20, 2020, the scope of motor vehicles exempt from inspection was expanded. On the basis of exempting non-operational mini and micro passenger vehicles with 6 seats or fewer from inspection within 6 years, non-operational mini and micro passenger vehicles with 7 to 9 seats (excluding vans) within 6 years were also included in the exemption range. On-site testing: For non-operational mini and micro passenger vehicles (excluding vans) older than 6 years but less than 10 years, the inspection frequency was adjusted from once per year to once every two years, but on-site testing is still required for the annual inspection.

Where is the center point of an intersection?

It is where the center lines of two roads intersect, usually where traffic police stand to direct traffic. Large intersections typically have a marked point, while smaller ones generally do not. Below is related information about turning at the center of an intersection: 1. When turning left: Vehicles must turn closely around the center point of the intersection. At large intersections, there is usually a circle with diagonal lines inside, which marks the center point—often where traffic police direct traffic. 2. When making a left turn: Proceed near the center point before turning, meaning turning closely to the left side of the center point, also known as making a tight turn. This rule mainly prevents collisions with vehicles on the left. For intersections without markings, the center point is simply the intersection point.

What does the funnel-shaped warning light mean?

Oil-water separator warning light, below is its related introduction: 1. Definition: Oil-water separation mainly utilizes the density difference between water and oil or their different chemical properties, employing gravity sedimentation principle or other physicochemical reactions to remove impurities or achieve the separation of oil and water. 2. Electrical separation: Electrical dehydration serves as the final method for oil-water treatment and is widely used in oil fields and refineries. Its principle involves placing the emulsion in a high-voltage AC or DC electric field. Due to the effect of the electric field on water droplets, the strength of the emulsion's interfacial film is weakened, promoting the collision and merging of water droplets, ultimately forming larger water droplets that separate from the crude oil. Since electrical dehydration of crude oil emulsions with high water content can cause electrical breakdown, making it impossible to establish the necessary electric field strength between the electrodes, the electrical dehydration method cannot be used independently and can only serve as a subsequent process to other treatment methods.

What is a Wheel Arch?

Wheel arch, short for car wheel arch, refers to the chrome trim strip along the upper edge of the tire, which is a semicircular component protruding from the fender above the car tire. Below is a related introduction to wheel arches: 1. Function of wheel arches: Mainly for decorative purposes and to meet the personalized needs of drivers. At the same time, from an aerodynamic perspective, wheel arches also conform to fluid dynamics, helping to reduce the drag coefficient. Wheel arches are not an essential component of a vehicle and may vary depending on the design philosophy of the car manufacturer. 2. Benefits of wheel arches: Installing wheel arches on a car, especially for non-white cars like black or red ones, not only enhances visual appeal but also makes the car body appear lower and highlights the streamlined curvature of the vehicle.
