Why is the air conditioning cooling effect of a small car not good?

What Are the Causes of Car Brake Failure?

There are several reasons that can cause car brake failure, including lack of necessary maintenance of the braking system, severe overloading, and improper operation leading to mechanical failure. Lack of necessary maintenance of the braking system: too many impurities in the brake master cylinder, poor sealing, failure of the vacuum booster pump, excessively dirty brake fluid or mixing different types of brake fluid causing air resistance when heated, leakage in the brake master cylinder or wheel cylinders, or air leakage in the air reservoir or pipe connections. Severe overloading: under the effect of gravitational acceleration, the vehicle's motion inertia increases, directly leading to brake failure. Improper operation leading to mechanical failure: for example, prolonged downhill driving can cause the brake pads to generate heat through friction, carbonization of the brake drum, and complete failure of the braking function. Correct measures to take after car brake failure: promptly identify the issue and decelerate to stop, avoiding continued high-speed driving; use the handbrake appropriately to control the vehicle, avoiding pulling it all the way or too quickly. Shift to a lower gear appropriately to control the speed.

Are Vehicles Exempt from Inspection Within Six Years?

Vehicles within 6 years of registration are exempt from inspection. Exempt vehicles generally refer to those registered for no more than six years and are non-commercial small vehicles with 6 seats or fewer. These vehicles require inspection every two years. Vehicles registered for more than 6 years require annual inspection. Below is relevant information about vehicle annual inspections: Vehicle Annual Inspection Schedule: For passenger cars and blue-plate minivans, within the first six years after registration, inspections are required every two years; after six years, inspections are required annually; after ten years, inspections are required annually; after fifteen years, inspections are required twice a year. For trucks, inspections are required annually after registration, and after ten years, inspections are required twice a year. Vehicle Annual Inspection Regulations: If a vehicle is found by traffic police to have not undergone annual inspection, the owner may be fined or the vehicle may be impounded. Additionally, in insurance contracts, vehicles that have not undergone timely annual inspections are considered unqualified, and no claims will be paid in the event of an accident.

Is Overtaking on the Right Side Allowed?

China's traffic laws explicitly state that "overtaking on the right side" is a traffic violation and strictly prohibited. In mainland China, traffic generally keeps to the right, leaving the left side as the usual space for overtaking. Overtaking on the right can easily lead to collisions with pedestrians and is highly unsafe. Below are relevant details about overtaking: Definition of Overtaking: Overtaking refers to the process where a following vehicle changes lanes to the rear side of the vehicle ahead, passes it, and then returns to the original lane. The lane typically used for overtaking is the inner lane, which is closer to the center of the road and farther from the shoulder. Dangers of Improper Overtaking: In regions where traffic keeps to the left, the overtaking lane is the right lane. According to regulations: drivers who overtake on the right side will be penalized with 3 demerit points and a fine of up to 200 RMB. The right side is the blind spot for left-hand drive vehicles, severely limiting visibility. Vehicles being overtaken may not notice the violating vehicle on the right, increasing the risk of collision when changing lanes to the right.

Is 225 Considered a Wide Tire?

225 and 235 are both considered wide tires for A-segment cars. Since the average width for most A-segment cars ranges between 195mm and 205mm, with higher-end models reaching 215mm and 225mm, 225 and 235 exceed this average. In other words, whether a tire is considered wide depends on the average width for its vehicle segment. Generally, compact cars have tire widths around 195mm, while subcompact cars are typically around 185mm. Below is an introduction to tires: Tire Specifications: Tire specifications are commonly represented by a set of numbers. The first number indicates the tire section width, and the second denotes the rim diameter in inches. For example, 205/55R16 means a tire width of 205mm, an aspect ratio of 55, and a rim diameter of 16 inches for a radial tire. Tire Width: Tire width is usually measured in millimeters. Wider tires have a larger contact patch, which, given the same tread pattern and material, provides better grip and traction in straight-line driving. However, this also leads to increased fuel consumption. Therefore, when replacing or upgrading tires, it's essential to weigh the pros and cons.

How often should the spark plugs be replaced in a Sagitar 1.4T?

The replacement interval for spark plugs in a Sagitar 1.4T primarily depends on the mileage. It is recommended to replace the spark plugs once every 40,000 to 60,000 kilometers. Spark plugs are a crucial component of the gasoline engine's ignition system. They introduce high voltage electricity into the combustion chamber and generate a spark by jumping the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. Steps for replacing spark plugs: Open the hood, lift the engine's plastic cover, and remove the high-voltage distributor wires. Mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust and ensure they are thoroughly cleaned. Place the new spark plugs into the spark plug holes, hand-tighten them a few turns, and then use the socket to tighten them further. Reinstall the high-voltage distributor wires according to the firing order and secure the cover.
