Accumulate a little car knowledge a day (II)

1. Parking lights Some cars have this situation: If you forget after parking and turning off the engineTurn off the turn signal lever, and the small light on this side will stay on until your battery runs out. This is the function of the parking light.

2. Not all models have rear wipers. Car rear wipers are common in SUVs or hatchbacks, but sedans almost do not have rear wipers. This is because the sedan has more trunk cover, so the airflow will go backwards along the tail, thus taking away the dirty things on the rear window, so the rear wiper does not play much for the sedan.

3. Ensure visibility. Before starting the car, the driver should ensure good visibility. On rainy days, the rearview mirror is easy to get wet and make the driver's vision blurred. Be sure to dry the rearview mirror so that you can clearly observe the movement of the rear vehicle while driving and react quickly.

4. No matter what brand your car is, they will make a clicking sound when we turn on the turn signal.This is because the turn signal can be turned on and off by a relay, and the principle of this relay is to rely on an electromagnet to repeatedly attract an electric shock, and it will make a sound every time it is touched.

5. Basic knowledge of automobiles Collection of automobile terminology Wheelbase (mm): the distance from the center of the front axle of the automobile to the center of the rear axle. Turning radius (mm): When the car turns, the center plane of the outer steering wheel of the car is the radius of the trajectory circle on the vehicle support plane. The turning radius when the steering wheel turns to the limit position is the minimum turning radius.

6. The car is not born as a whole, but an overall shape composed of various parts, in which the "chassis" plays an important role in supporting the body, engine and its parts. The car chassis consists of four parts: transmission system, driving system, steering system and braking system. Each system interacts to ensure the normal operation of the vehicle.

Easy Car News According to the latest retail sales data statistics of the Automobile Market Research Branch of the China Automobile Circulation Association (Car Federation), the retail sales of the passenger car market reached 1.3 million in February 2023, an increase of 4% year-on-year and 5% month-on-month.

Affected by the epidemic, after car sales fell by 78.5% in February, there is finally good news... _Baidu Knowledge...

1. Affected by the epidemic, car sales were dismal in February. On March 9, the data released by the Passenger Association showed that the national passenger car market retailed 220,000 units in February 2020, down 75% year-on-year in February 2019.

2. It decreased by 75% year-on-year, which is an ultra-low base compared with the data of 19% year-on-year due to the Spring Festival in February 2019, indicating that the car market is seriously abnormal this year. Judging from the cumulative year-on-year decline of 40% in retail from January to February, the impact of the epidemic factor is much greater than the Spring Festival factor.

3. Affected by the epidemic, the domestic automobile industry was forced to press the "pause button". The overall car market situation in February can be described as bleak.

4. Image source: Passenger Car Federation On March 9, the Passenger Federation released data that in February, the national passenger car market retailed 220,000 units, plummeting by 75% year-on-year.From January to February, retail sales fell by 40% year-on-year, and the impact of epidemic factors was far greater than the interference of Spring Festival factors.

5.

What is the national second car?

The abbreviation of the second phase of the national emission standard is equivalent to the emission standard of Europe II, that is, the content of exhaust pollutants is equivalent to that of Euro II.

The national second car means that the exhaust emission of the car meets the second phase of the national emission standards.Country 1 Country 2 Country 3 Country 4 refers to the emission standards of automobile exhaust. Cars emit carbon monoxide, hydrocarbons and nitrogen oxides, particles, carbon smoke and other harmful gases from exhaust gases.

National one and two vehicles refer to internal combustion locomotives whose exhaust emissions have reached the first stage and the second phase of emissions. Compared with the first phase of the national emission standard (referred to as the national 1 standard), the national 2 standard reduces the emission of carbon monoxide by 30.4%, hydrocarbons and nitrogen oxides by 55.8%.

The first phase of the country is the first phase of the national motor vehicle pollutant emission standard, the second phase of the country, and so on. From January 1, 2017, the national five standards, that is, the national fifth phase of motor vehicle pollutant emission standards, will be implemented.

National first-class vehicle refers to motor vehicles produced under the emission standards implemented in the first phase of the country, referred to as national first-class standard vehicles.That is to say, most of the motor vehicles purchased from January 1, 1999 to December 31, 2003 belong to the scope of national vehicles.

When the car leaves the factory, it means that it meets the national emission standard level 2 (referred to as country 2). However, at that time, there was no national emission label, and the European emission standard was used, called Euro 2.

Car Knowledge Learning (II)

1. Ensure visibility Before starting the car, the driver should ensure good visibility. On rainy days, the reversing mirror is easy to get water and blur the driver's vision. Be sure to dry the reversing mirror for driving. It can clearly observe the movement of the rear vehicles and react quickly. The phone number of the car accident. We drive on the road, and we can't guarantee that we won't have a car accident.

2. Not all models have rear wipers. Car rear wipers are common in SUVs or hatchbacks, but sedans almost do not have rear wipers. This is because the sedan has more trunk cover, so the airflow will go backwards along the tail, thus taking away the dirty things on the rear window, so the rear wiper does not play much for the sedan.

3. Turning radius (mm): When the car turns, the center plane of the outer steering wheel of the car is the radius of the trajectory circle on the vehicle support plane. The turning radius when the steering wheel turns to the limit position is the minimum turning radius. Maximum total mass (kg): the total mass when the car is fully loaded.

4. In the combustion chamber of the sealed cylinder, the spark plug instantly ignites a certain proportion of gasoline and air mixture at the right time.It will produce a huge explosive force, and the top of the combustion chamber is fixed. The huge pressure forces the piston to move down, push the crankshaft through the connecting rod, and transmit power to the drive wheel through a series of mechanisms, and finally push the car.

5. The quality of the whole vehicle equipment (KG): the quality of the car is fully equipped, that is, the quality of the manufacturer at the factory, including the quality of various lubricants, oils, tools, spare tires, etc. It is usually what we call empty load mass and vehicle weight. Maximum total mass (KG): the total mass when the car is fully loaded. The total mass when sitting full of people and full of goods.

6. Why does the turn signal always have a clap sound? No matter what brand your car is, they will make a clicking sound when we turn on the turn signal.
