No air coming out from the driver's side of the car air conditioner may be due to damage or failure to open the air duct separator valve, or incorrect air outlet mode settings. Below is more information about car air conditioners: 1. Cooling principle: When the car air conditioner is cooling, the compressor clutch engages, causing the engine to drive the compressor. The compressor continuously compresses the refrigerant and delivers it to the evaporator. Inside the evaporator, the refrigerant expands and absorbs heat, cooling the evaporator which in turn cools the air blown by the blower. 2. Heating principle: When the car air conditioner is heating, high-temperature coolant from the engine passes through the heater core. At this time, the air blown by the blower also passes through the heater core, allowing warm air to be blown out from the air conditioner vents.

How to Practice Driving Without a Sense of Direction?

Practice techniques for driving without a sense of direction: 1. Gentle steering: When adjusting the direction of the vehicle, steer gently and smoothly. Pay attention to the conditions behind and in front of the vehicle, making slight adjustments with small angles to gradually correct the driving direction. 2. Avoid abrupt or fast movements: Never change the vehicle's direction too abruptly or quickly while driving. For example, if the vehicle is initially tilting to the right, an overly aggressive adjustment might cause it to tilt to the left or even cross the road edge line, leading to test failure. During high-speed driving (e.g., in the third driving test), adjust the vehicle's direction by turning the steering wheel just two or three finger-widths, preferably in several small steps. 3. Posture: Sit upright and straight while driving, look far ahead, and keep your grip on the steering wheel relaxed. Ensure the vehicle's direction aligns with your line of sight. The farther you look ahead, the sooner you can detect any issues with the vehicle.

What are the penalties for mixing passengers and cargo in a van?

Mixing passengers and cargo in a van results in a deduction of 6 points, a fine ranging from 500 to 2000 yuan, and the vehicle will be detained by traffic police until the illegal status is rectified. Below are relevant details: Definition of mixing passengers and cargo: This generally refers to using a truck to carry passengers or using a passenger vehicle to transport goods. If only the trunk or roof rack of the van is used to carry goods, this does not constitute mixing passengers and cargo. However, if goods are piled up on the rear seats or even the front seats, this is considered mixing passengers and cargo and is illegal. Traffic police can enforce penalties, and offenders will face point deductions and fines if caught.

What are the rules for the reverse parking test in Subject 2?

Detailed introduction to the rules of reverse parking in Subject 2: 1. Failure to enter the parking space: Some students tend to get nervous during the test. The system judges that the main reasons for not entering the parking space are too fast speed, poor clutch control, and inaccurate stopping point, resulting in failure in the first test item of Subject 2. 2. Crossing the line during reverse parking: There are many situations where the line is crossed during the test. For example, turning the steering wheel too late, the car body not being straight, or the speed being too fast. 3. Not following the prescribed route: Due to nervousness during the test, some students directly proceed to the next test item after completing the right reverse parking, ignoring the left reverse parking. Some students directly perform the left reverse parking first and then the right reverse parking, which is also unqualified. 4. Scoring standards for reverse parking: Not following the prescribed route sequence, the car body crossing the line, failure to enter the parking space, the project completion time exceeding 210s, and not having both front wheels touch the ground beyond the control line before reversing will all result in a deduction of 100 points. Stopping for more than 2s during the process will result in a deduction of 5 points per time.

How Often Should You Change the Oil for a Scooter?

For a new scooter, change the oil every 1,000 kilometers initially, and then every 3,000 kilometers thereafter. Below is an introduction to the functions of engine oil: The Lubricating Role of Engine Oil: Between the piston and cylinder, as well as between the main shaft and bearing bush, there is rapid relative sliding. To prevent excessive wear of parts, an oil film needs to be established between the two sliding surfaces. A sufficiently thick oil film separates the surfaces of the relatively sliding parts, thereby reducing wear. The Auxiliary Cooling Role of Engine Oil: Due to its relatively low specific heat value and its location inside the engine, engine oil itself does not have a cooling function. However, as the engine generates heat from fuel combustion during operation, the engine oil can carry the heat back to the oil tank and then dissipate it into the air, assisting the radiator in cooling the engine. The actual cooling is performed by the water outside the engine casing.

What are the adverse effects of driving on icy and snowy roads?

Driving on icy and snowy roads has several adverse effects, including wheel slippage, sideslip, increased risk of rollover, difficulty in control, loss of steering control, and extended braking distance. Here are some precautions for driving on icy and snowy roads: 1. Maintain a safe distance: Do not follow other vehicles too closely, as sudden braking by the vehicle ahead can easily lead to rear-end collisions. Drivers should maintain an appropriate safety distance based on terrain, speed, and load conditions. 2. Avoid overtaking if possible: If overtaking is absolutely necessary due to urgency, choose a wide, flat section with minimal snow and ice, and never force an overtake. When meeting another vehicle, select a flat and wide section, maintain sufficient lateral distance, and avoid getting too close to the roadside. If the road is narrow, the driver with more space should yield by stopping or reversing. 3. Avoid sharp turns: When turning, reduce speed as much as possible in advance, hold the steering wheel firmly, and turn slowly. Increase the turning radius as much as possible without obstructing oncoming traffic to minimize centrifugal force. Never make sudden sharp turns to prevent sideslip or loss of control. 4. Use engine braking to slow down: Avoid emergency braking or sharp steering to evade obstacles, as this may cause sideslip or loss of steering control.

What does a metal belt-type CVT system mainly include?

CVT system mainly includes basic components such as the driving pulley set, driven pulley set, metal belt, and hydraulic pump. The following are relevant details: 1. Metal belt: The metal belt consists of two metal rings and hundreds of metal plates. 2. Driving pulley set and driven pulley set: Both the driving set and the driven pulley set are composed of a movable disc and a fixed disc. The side of the pulley near the oil cylinder can slide on the shaft, while the other side is fixed. Both the movable disc and the fixed disc have a conical surface structure, and their conical surfaces form a V-shaped groove to engage with the V-shaped metal transmission belt. The power output from the engine's output shaft is first transmitted to the driving pulley of the CVT, then transmitted to the driven pulley through the V-shaped transmission belt, and finally transmitted to the wheels through the reducer and differential to drive the car.
