The 15:25 ratio has a higher rotation speed for rotary tillers. Functions of rotary tillers: Rotary tillers are agricultural implements paired with tractors to perform plowing and harrowing operations. They are widely used due to their strong soil-breaking capability and the ability to create a flat surface after tilling. Additionally, they can chop up root stubble buried beneath the soil surface, facilitating the operation of seeders and providing a good seedbed for subsequent sowing. Classification of rotary tillers: Based on the configuration of their tiller blades, rotary tillers are categorized into three types: horizontal-axis, vertical-axis, and inclined-axis. Proper use and adjustment of rotary tillers are crucial for maintaining their technical condition and ensuring tillage quality. Roles of rotary tillers: Rotary tillers help break the plow pan, restore soil structure, improve water retention and moisture conservation, eliminate certain weeds, reduce pests and diseases, level the ground surface, and enhance the standards of agricultural mechanization.

Does Car Air Conditioning Drip Water?

It is normal for a car to drip water when the air conditioning is on. Reasons: The car's air conditioning system has a component called an evaporator installed inside the dashboard. When the air conditioning is turned on, the surface temperature of the evaporator becomes very low. The moisture in the hot air inside the car condenses on the heat-absorbing fins of the evaporator. The water droplets are collected by the plastic housing of the evaporator and discharged outside the car through a pipe, which is why water drips. Precautions: If the air conditioning is too cold, moisture in the air may condense on the outside of the vents, creating a phenomenon where white mist appears. Moisture in the air may also condense on the plastic housing of the evaporator or the surface of the plastic pipes that deliver cold air, resulting in dripping water. Additionally, this can happen if the air humidity inside the car is too high.

What does the FV license plate represent?

FV license plates represent Mainland vehicles entering Hong Kong, which are special license plates issued by the Hong Kong government for self-driving vehicles from the Mainland. Vehicles with FV license plates can travel between the Mainland and Hong Kong, with 180 round trips allowed to Hong Kong, and no limit on the number of round trips per day. They can enter and exit through the Shenzhen Bay Port, and after midnight, they can use the Futian Huanggang Port. Currently, vehicles passing through the Hong Kong-Zhuhai-Macao Bridge mainly use Guangdong Z license plates, with fewer FV license plates. This is not only because the application requirements for FV license plates on the Hong Kong-Zhuhai-Macao Bridge are higher than those for Guangdong Z license plates but also due to the influence of the wave of Hong Kong and Macao residents investing in the Mainland.

What Causes No Sound When Playing Music via Bluetooth Connection Between Phone and Car?

The reasons for no sound when playing music via Bluetooth connection between phone and car are: 1. The volume on the car navigation system or phone is not turned on; 2. Some phones' music playback programming is incompatible with the car model's pairing code; 3. The multimedia music feature of the car's Bluetooth is not enabled; 4. The media audio on the phone is not turned off, causing signal interference with the Bluetooth function. The solution to no sound when playing music via Bluetooth connection between phone and car is: Enter the Bluetooth settings interface on the phone, where there are two options: phone audio and media audio. After connecting to the car's Bluetooth, both options are enabled by default. You need to turn off the media audio and keep the phone audio, which ensures that the three functions—Bluetooth calls, car music playback (or radio), and phone navigation announcements—do not interfere with each other.

Shift to P Gear First or Turn Off the Engine First?

Shift to P gear first. The correct parking sequence is: after stopping the vehicle with the foot brake, pull up the handbrake, shift into P gear, release the foot brake, and finally turn off the engine. Additionally, pulling the handbrake before shifting to P gear is intended to have the handbrake bear most of the impact force, reducing damage to the transmission, especially the P gear. P gear is a common gear in automatic transmission vehicles, usually located at the front of the gear shift console, in front of the R gear, designed to lock the axle when the car is stationary on a slope. P gear is a special neutral gear that mechanically locks the output shaft of the transmission to secure the vehicle, functioning as a parking brake to prevent the vehicle from moving.

Is Brake Fluid Really Unnecessary to Replace?

Brake fluid must be replaced. When the braking system operates, it transmits energy through the brake fluid. Liquids generally do not deform easily and are not compressible, making them relatively stable in energy transmission. However, the working environment of brake fluid involves high temperatures, especially during continuous braking, where temperatures often exceed 100 degrees Celsius. This severely tests the quality of the brake fluid. Generally, brake fluid should be considered for replacement once its water content exceeds 3%, and it must not be used if the water content exceeds 5%. Most brake fluids are inherently corrosive, and this corrosiveness increases with higher water content. Long-term failure to replace brake fluid can damage the metal and rubber components of related parts, leading to a faster decline in braking performance. In most cases, brake fluid should be replaced every two years, though some high-quality brake fluids may last slightly longer.

What does VVT engine mean?

VVT engine refers to an engine equipped with a Variable Valve Timing (VVT) system. This system adjusts the phase of the engine camshaft through its control and execution mechanisms, allowing the timing of valve opening and closing to vary with engine speed. This enhances air intake efficiency and increases engine power. The principle of a VVT engine is: it improves intake and exhaust by operating the throttle valve, which is directly or indirectly driven by the cam on the camshaft. During each intake and exhaust cycle, the cam-driven valve opens (lifts) for a specific duration (overlap time).
