The function of an automotive belt is to serve as a connecting link between the upper and lower parts. The upper part connects to the timing wheel of the engine cylinder head, while the lower part connects to the crankshaft timing wheel. The timing wheel is connected to the camshaft, which has cams. The contact point is the small rocker arm, which generates pressure through the power transmitted by the timing belt, thereby lifting the valves. Below is an introduction to automotive belts: 1. Advantages: Automotive belts have been used in engines for a long time, featuring mature technology, lower costs, and reduced noise. However, they require regular inspection and maintenance, typically needing replacement every 50,000 to 100,000 kilometers. Timing chains offer significant advantages such as compact structure, high power transmission efficiency, excellent reliability and wear resistance, and being maintenance-free for life. However, compared to traditional timing belts, they generally produce slightly more noise. 2. Silent tooth chains: With technological advancements, some vehicles now use silent tooth chains, which produce even less noise than timing belts. It is believed that the widespread adoption of such timing chains will bring more convenience to automotive users.

What is the structural principle of a compressor?

After being cooled and turned into a high-pressure, low-temperature liquid through the condenser's cooling tubes, it then passes through the receiver-drier for dehumidification and buffering, flowing toward the expansion valve with relatively stable pressure and flow rate. After throttling and pressure reduction, it finally flows into the evaporator. The refrigerant evaporates immediately upon encountering a low-pressure environment, absorbing a large amount of thermal energy. The following are specific details about the compressor: 1. Classification: Air conditioning compressors can be divided into fixed displacement compressors and variable displacement compressors. 2. Function: The air conditioning compressor plays the role of compressing and driving the refrigerant in the air conditioning refrigerant circuit. The working circuit is divided into an evaporation zone (low-pressure zone) and a condensation zone (high-pressure zone). The indoor unit and outdoor unit belong to the high-pressure or low-pressure zone respectively (depending on the working state), and the compressor is generally installed in the outdoor unit. The compressor draws the refrigerant from the low-pressure zone, compresses it, and sends it to the high-pressure zone for cooling and condensation, releasing heat into the air through the heat sink. The refrigerant also changes from a gaseous state to a liquid state, with increased pressure. The refrigerant then flows from the high-pressure zone to the low-pressure zone, being sprayed into the evaporator through the capillary tube, where the pressure drops sharply, and the liquid refrigerant immediately turns into a gaseous state, absorbing a large amount of heat from the air through the heat sink. As the machine continuously operates, it continuously absorbs heat from the low-pressure zone into the refrigerant and then releases it into the air in the high-pressure zone, thereby regulating the temperature.

What Causes the ECU Fuse to Blow Immediately After Insertion?

This is a short circuit phenomenon. Disconnect the computer and then reinsert the fuse. If it still blows, it indicates a wiring issue. If it doesn't blow, then the computer needs to be inspected and repaired. Below are detailed introductions to the ECU: 1. ECU Introduction: The ECU, or Electronic Control Unit, is similar to an ordinary computer, composed of a microprocessor (CPU), memory (RAM, ROM), drivers, and other large-scale integrated circuits. It is also known as the 'vehicle computer' or 'on-board computer.' The ECU acts like the brain of the car, controlling the engine's power output values. 2. ECU Tuning Methods: Flash tuning involves retaining the original ECU hardware and writing a new operating management program into the ECU, altering the factory settings. Flash tuning is also referred to as ECU remapping, commonly known as 'flashing' in layman's terms. Parameters such as engine horsepower and torque can be adjusted. Flash tuning modifies the ECU by reassembling the program, and since the ECU controls the engine's power output, this achieves the goal of enhancing performance. Although this modification method is limited by the original ECU and sensors, resulting in a relatively smaller adjustable range, it does not compromise other factory functions and offers greater stability and safety.

What is the working principle of Toyota eCVT transmission?

Toyota eCVT transmission works by utilizing a set of planetary gears to achieve the 'fusion' of engine power and motor power. Here is an extended introduction to it: Introduction to eCVT: eCVT is actually just a power combination scheme, not a transmission in the traditional sense. Because eCVT has a planetary gear structure, it also requires transmission fluid replacement. Timely Replacement: Any fluid in a vehicle has a shelf life and service life, and needs to be replaced after a certain mileage or period of use.

How to Judge the Distance from the Front of the Car?

Here are the steps to judge the distance from the front of the car: 1. When you can see the upper edge of the rear bumper of the car in front, the distance is approximately 1m. 2. When you can see the lower edge of the rear bumper of the car in front, the distance is approximately 2m. 3. When you can see the lower edge of the rear tires of the car in front, the distance is approximately 3m. Here are the steps to judge the left and right distance from the front of the car: 1. Imagine a person about 1.7 to 1.8 meters tall in front of you, with feet about 10 cm high, knees about 45 cm high, and the lower part of the hips about 70 cm high. 2. When the front of your car rises from the ground to the person's feet or heels and stays there, the distance between the front of your car and the person is about 3 meters. 3. When the front of your car rises to the height of the person's knees (i.e., you can see the person's knees), the distance between the front of your car and the person is about 2 meters. 4. When the left or right front of your car rises to the lower part of the person's hips, the distance between the front of your car and the person is about 0.3 meters.
