What does 'inside' mean on tires?

What are the reasons for a sudden increase in car fuel consumption?

The reasons for a sudden increase in car fuel consumption include the following: 1. Failure to match or unsuccessful matching with the engine control unit after cleaning the throttle body. 2. Faults in the engine's electronic control system, leading to an overly rich air-fuel mixture and increased fuel consumption. 3. Damage to the engine ignition coil or spark plugs, fuel injector leaks, etc., resulting in higher fuel consumption. 4. Malfunction in the engine cooling system, causing the engine temperature to remain too low and stay in warm-up mode. 5. Excessive carbon buildup in the engine, leading to incomplete combustion. 6. Faults in the fuel tank ventilation system, causing fuel vapor leaks.

What Causes No Airflow from Car Air Conditioning Vents?

Here are the reasons for no airflow from car air conditioning vents: 1. The gear switch or knob is not properly adjusted to the correct position. 2. Damage to the air duct diverter valve. First, check if the vents are open and if the switch is properly adjusted. If the vents are open but there is still no airflow, inspect for any blockages in the vents. It is recommended to seek assistance from a professional auto repair shop. Here is some related information about the air conditioning system: 1. Parameters that can be set for the car air conditioning include the compressor cooling switch, temperature level, vent direction, airflow volume, internal/external circulation, and windshield defogging. 2. The left knob adjusts the air conditioning temperature—clockwise to increase temperature and counterclockwise to decrease it. The middle knob controls the vent direction; adjusting it to the windshield defogging position activates the rearview mirror heating when the middle button is pressed. The right knob regulates the airflow volume, and the middle button sets the air circulation mode.

What does car displacement mean?

Car displacement refers to the volume of fluid inhaled or discharged per stroke or cycle. The space volume that the piston moves from the top dead center to the bottom dead center is called the cylinder displacement. If the engine has several cylinders, the sum of the working volumes of all cylinders is called the engine displacement. It is generally expressed in liters (L). Engine displacement is one of the most important structural parameters, which can represent the size of the engine better than the cylinder diameter and the number of cylinders. Many indicators of the engine are closely related to the displacement. The following is an introduction related to displacement: 1. Most domestic cars have a car model composed of pinyin letters and Arabic numerals at the rear, which includes the following three parts. The first part consists of 2 or 3 pinyin letters, which is the code to identify the name of the enterprise. 2. Generally, the larger the displacement, the more energy the engine releases per unit time (that is, converting the chemical energy of fuel into mechanical energy), which means better "dynamic performance". Therefore, off-road vehicles and sports cars usually have relatively large displacements.

What tires correspond to 5.5j rims?

The J-number of a rim represents the width of the wheel in inches; 5.5j is slightly wider than 6j. Here is some relevant information about rims: 1. Introduction: A rim is the rotating part of the wheel that connects the tire's inner contour to the hub via spokes, i.e., the metal component mounted on the axle that supports the tire. It is also called a wheel rim, steel rim, or hubcap. Rims come in various types based on diameter, width, manufacturing method, and material. 2. Types of Rims: Rims are also known as wheel rims. Depending on the characteristics and requirements of different vehicle models, the surface treatment processes for rims vary, mainly divided into painting and plating. For ordinary vehicles, rims are less focused on appearance, with good heat dissipation being a basic requirement. The manufacturing process typically involves painting, where the rim is first sprayed and then baked, making it cost-effective, vibrant in color, and long-lasting. Even when the vehicle is scrapped, the rim's color remains unchanged.

What are the symptoms of insufficient refrigerant in a car's air conditioning system?

When the car's air conditioning system is low on refrigerant, the following symptoms may occur: During normal continuous operation of the air conditioning, if bubbles persistently appear in the sight glass, it indicates insufficient refrigerant and the need for a recharge. Open the car's hood and check the air conditioning system connections for oil stains. If present, this typically indicates a refrigerant shortage. It's recommended to clean the area before recharging. When the air conditioning is turned on, if bubbles appear in the sight glass every 1-2 seconds continuously; if there are oil stains at pipe connection points; or if there's no noticeable temperature difference between the high and low pressure sides when touched by hand - these all indicate minor refrigerant leakage in the system that requires replenishment. Users who have operated the system for more than six months should check both the indoor unit's pipe connections and outdoor unit's valves for obvious signs of oil leakage. Visible oil leakage indicates system leakage, as oil and refrigerant are mutually soluble - oil leakage means refrigerant leakage, and vice versa.

What Are the New Policies on Scrapped Vehicles?

The latest vehicle scrapping policies include the following: 1. Non-operational small and micro vehicles are no longer subject to mandatory scrapping. However, if the vehicle has been in use for over 15 years, it must undergo two inspections per year. Vehicles that fail the inspection will be mandatorily scrapped. 2. Taxis have a service life of 8 years and will be mandatorily scrapped upon reaching this age. 3. Domestic pickup trucks have a service life of 15 years and will be mandatorily scrapped upon reaching this age. 4. Medium-sized taxi passenger vehicles have a service life of 10 years and will be mandatorily scrapped upon reaching this age. 5. Heavy, medium, and light-duty trucks have a service life of 15 years and will be mandatorily scrapped upon reaching this age. 6. Semi-trailer tractors have a service life of 15 years and will be mandatorily scrapped upon reaching this age. 7. Micro trucks have a service life of 12 years and will be mandatorily scrapped upon reaching this age.
