What Causes Ice Formation in the Car's Evaporator Box?

There are several reasons for ice formation in the car's air conditioning evaporator box: 1. The expansion valve's adjustment is too small, resulting in excessively low low-pressure. 2. Insufficient refrigerant in the system leads to excessively low evaporation pressure. 3. The internal circulation filter is clogged. 4. The temperature control (or temperature sensor) malfunctions, causing the compressor to run continuously. 5. The variable displacement compressor's energy control valve (pressure regulating valve) fails, keeping the compressor operating at full capacity, which results in excessively low low-pressure and causes the evaporator to freeze. Below are solutions for ice formation in the car's air conditioning evaporator box: 1. Check if the temperature control sensor is in the correct position. 2. Adjust the temperature control to a lower setting; if it cannot be adjusted, replace the temperature control. 3. Inspect the air conditioning computer control for any faults. 4. Apart from the compressor running continuously, check if the evaporator box fan's inlet and outlet dampers are blocked.

How Long Can You Drive with Low Oil Pressure?

When low oil pressure occurs, it is recommended not to continue driving. Continuing to drive can lead to poor engine lubrication, exacerbating friction and wear on components. Additionally, oil plays a crucial role in cooling and heat dissipation. Low oil pressure can cause the engine to overheat internally, potentially leading to further damage such as bearing seizure or cylinder scoring. Below are the causes and solutions for low oil pressure: 1. Insufficient Oil Level: This issue is relatively easy to resolve—simply add the same type of oil. 2. Contaminants in the Oil: If there are impurities in the oil, they can clog the oil passages, resulting in low oil pressure. In this case, the oil needs to be replaced. 3. Oil Too Thin: If the oil is too thin, its sealing performance is compromised, allowing oil to leak through gaps and causing low oil pressure. This requires replacing the oil with a higher viscosity grade. 4. Faulty Oil Pressure Sensor: A damaged oil pressure sensor can lead to misjudgment of the oil's condition. In such cases, professional assistance is required for repairs.

What is the Difference Between Multi-Link and Torsion Beam?

The differences between multi-link and torsion beam are as follows: 1. Multi-link suspension is an independent suspension, while torsion beam suspension is a non-independent suspension. In an independent suspension, each wheel is individually connected to the frame or body via an elastic suspension system, whereas in a non-independent suspension, the body and tires are not directly connected. 2. The multi-link independent suspension consists of links, shock absorbers, and damping springs. This type of suspension uses more links than a typical suspension. A four-link or five-link suspension is referred to as a multi-link independent suspension. 3. Due to the increased number of links used in this type of suspension, it allows the wheels to remain as perpendicular to the ground as possible, minimizing body roll to the greatest extent. This helps maintain excellent stability while driving. 4. The torsion beam non-independent suspension is not widely used in vehicles because this type of suspension has relatively high rigidity. The torsion beam independent suspension connects the two rear wheels of the vehicle on a single axle. When driving on rough road conditions, if one side of the wheel experiences jitter, the other side will also exhibit the same jitter phenomenon.

What kind of oil does Toyota use?

Toyota vehicles use 0W20 or 5W20 engine oil. It is best not to use oil with a viscosity exceeding 5W30. Toyota vehicles are generally equipped with naturally aspirated engines, so standard oil will suffice. The functions of engine oil are as follows: 1. Reducing friction and high temperatures: A sufficiently thick oil film separates the surfaces of relatively sliding parts, thereby reducing wear. 2. Sealing effect: Engine oil can form a seal between the piston rings and pistons, reducing gas leakage and preventing external contaminants from entering. 3. Anti-rust effect: Lubricating oil adheres to the surface of parts, preventing contact with water, air, acidic substances, and harmful gases. 4. Cushioning effect: When the pressure in the engine cylinder rises sharply, suddenly increasing the load on the pistons, piston skirts, connecting rods, and crankshaft bearings, this load is transmitted and lubricated through the bearings, cushioning the impact load. 5. Cleaning effect: Good engine oil can carry carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank through circulation, washing away dirt generated on the working surfaces of parts through the flow of the lubricating oil.

Are 150cc Motorcycles Exempt from Purchase Tax?

Consumers purchasing motorcycles with an engine displacement of ≤150cc are no longer required to pay the 10% vehicle purchase tax. The "Purchase Tax Law" clearly stipulates that motorcycles with an engine displacement of ≤150cc are exempt from purchase tax, meaning consumers buying such motorcycles do not need to pay the 10% vehicle purchase tax, thereby reducing the financial burden on ordinary consumers. Below is some extended information about the purchase tax: 1. What is purchase tax: Purchase tax is a tax levied by tax authorities on the acquisition of specified goods and properties within the scope of the purchase tax system, such as vehicle purchase tax. Vehicle purchase tax is a tax levied on units and individuals who purchase specified vehicles within China, and it evolved from the vehicle purchase surcharge. 2. Scope of purchase tax: Purchases of motorcycles and electric motorcycles with an engine displacement of 150cc or below, as well as wheeled special-purpose machinery vehicles such as loaders, graders, excavators, and bulldozers, and special equipment like cranes and forklifts, no longer require tax declaration.

Is it allowed to overtake from the right side on a motor vehicle lane?

Overtaking from the right side is not permitted on a one-way dual-lane road. Additional information is as follows: 1. Traffic regulations stipulate: When overtaking, a motor vehicle should activate the left turn signal in advance, switch between high and low beams, or sound the horn. 2. On roads without a central dividing line or with only one motor vehicle lane in the same direction, the leading vehicle should reduce speed and move to the right to give way when it receives an overtaking signal from the following vehicle, provided conditions permit. 3. The following vehicle should overtake from the left side of the leading vehicle only after confirming there is sufficient safe distance. After maintaining a necessary safe distance from the overtaken vehicle, the following vehicle should activate the right turn signal and return to the original lane. 4. If there are two or more motor vehicle lanes in the same direction and the vehicle is traveling in the right lane, it is allowed to overtake a vehicle in the left lane. However, overtaking from the right side is not permitted on two-lane roads in the same direction.
