What Should You Pay Attention to When Sleeping in a Car with the Air Conditioning On in Summer?

It is best to choose a relatively open area and leave the window slightly open when resting, as when the vehicle is stationary, carbon monoxide produced by the engine can enter the car. If the air does not circulate, the high concentration of carbon monoxide in the car can be life-threatening. The maintenance methods for car air conditioning are as follows: 1. Do not adjust the air conditioning vent direction randomly: The air conditioning vents should be adjusted reasonably. Based on the principle that cold air sinks and hot air rises, when using the cooling function, the vents should be directed upward, and when using the heating function, the vents should be directed downward. 2. Start the air conditioning periodically in winter: In some areas, air conditioning may not be needed in winter, but prolonged disuse can lead to aging of rubber seals and drying of lubricating oil on internal components. Therefore, it is necessary to start the air conditioning regularly to ensure lubrication of the system and maintain good condition. It is recommended to start the air conditioning once a week in winter. 3. Avoid using the air conditioning for too long: Prolonged use of the air conditioning can cause excessive pressure on the condenser, which can significantly damage the cooling system. Therefore, each use of the air conditioning should not be too long. If the temperature inside the car is already comfortable, turn off the air conditioning for a while and then turn it back on later. 4. In summer, ventilate and cool the car before switching to internal circulation: Since the temperature inside the car is higher than outside, it is recommended to open the windows for ventilation first to expel the hot air inside. Once the temperature inside the car has dropped, switch the air conditioning to internal circulation. 5. Avoid using the internal circulation mode for too long: Internal circulation means the air is recirculated within the closed space of the car, leading to a continuous decrease in oxygen levels. Additionally, if gasoline in the cylinders does not burn completely, carbon monoxide from the engine may leak into the car, worsening the air quality inside and potentially harming the occupants.

What is the exhaust emission standard?

In 2001, China introduced the China Phase I emission standard with reference to European emission standards, followed by National II, National III, National IV, and National V. Currently, the domestic automobile exhaust emission standard in China is the National V standard. The National V emission standard was officially implemented on January 1, 2017, and the National VI standard will also be implemented in 2020. More details about the exhaust emission standards are as follows: 1. Introduction 1: The National IV automobile exhaust emission standard refers to the national fourth-stage motor vehicle pollutant emission standard. The main pollutants emitted by automobiles include hydrocarbons, nitrogen oxides, carbon monoxide, and particulates. Through the application of technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, the emission of automobile pollutants is controlled and reduced to below specified values. 2. Introduction 2: The National V automobile exhaust emission standard is equivalent to the Euro V standard in the European Union, which has been implemented since 2009. It imposes stricter limits on motor vehicle emissions such as hydrocarbons, nitrogen oxides, carbon monoxide, and suspended particles. From National I to National V, each upgrade in the standard reduces single-vehicle pollutants by 30% to 50%. 3. Introduction 3: Compared to the National V emission standard, the National VI emission standard is more stringent in terms of testing standards and pollutant emissions. The test cycle has been changed from NEDC to WLTC standards, with the addition of real-world driving emission tests. The pollutant limits are stricter, with National VI being approximately 40% to 50% more stringent than National V. The CO and HC limits are about one-third stricter compared to National V.

How Many Teeth Does a Gear Have?

Gears generally have a module (m) of ≥2. Below is relevant information about gears: 1. Composition: Typically consists of teeth, tooth spaces, end faces, normal planes, tip circles, root circles, base circles, and pitch circles. Each protruding part used for meshing is usually arranged radially, and the teeth of paired gears contact each other to enable continuous meshing operation; tooth spaces are the gaps between two adjacent teeth on a gear; end faces refer to planes perpendicular to the gear or worm axis on cylindrical gears or cylindrical worms; normal planes are planes perpendicular to the tooth line; tip circles are the circles where the tooth tips lie; root circles are the circles where the tooth spaces' bottoms lie. 2. Repair Methods: Gear repair methods include the reversal method, tooth insertion method, gear ring replacement method, plastic deformation method, and welding repair method. Gears often transmit power in one direction, leading to one-sided wear. When their structure is completely symmetrical, they can be flipped 180 degrees and reinstalled for use. If not symmetrical, the gear can first be annealed, the asymmetrical part cut off and welded to the other side of the gear, and then the gear can be heat-treated again.

Is it necessary to wait a full year for license upgrade after B2 downgrade?

After downgrading a B2 driver's license, it generally takes about one year to apply for reinstating the B2 driving qualification. 1. License downgrade system: The downgrade system only applies to large buses, tractors, city buses, medium buses, and heavy trucks, with step-by-step downgrades (minimum C1 class). 2. Cancellation of permitted vehicle classes: No downgrade applies to small cars or motorcycles. Note that if eligible for downgrade, only the highest-level permitted vehicle class will be canceled each time. For example, for a license with both B1 and B2 codes, only B1 will be canceled initially. 3. 12-point record: Applicants must wait one year without another 12-point violation record before applying for license upgrade.
