What Do You Need to Prepare for Driving on the Highway During the Pandemic?

How to Turn On the Car's Internal and External Air Circulation?

Regarding the usage of internal and external air circulation, the details are as follows: 1. The internal circulation symbol is: a circular arrow inside a car graphic, while the external circulation symbol is an arrow entering the car from outside. 2. Simply put: the car's internal circulation means the air inside the car is heated or cooled and then recirculated back into the car; external circulation means the air outside the car is heated or cooled and then brought into the car, allowing gas exchange between the inside and outside of the car. 3. Using external circulation: you can breathe fresh air from outside. When driving on the highway for a long time, the air inside the car may become stale, making you uncomfortable, and you can't open the windows. In this case, you should use external circulation to bring in fresh air. In winter, if the warm air feels too hot, you can turn off the fan and open the external circulation, which maintains the car's temperature while providing fresh air, making you feel more comfortable. 4. However, if you're using the air conditioning to lower the car's temperature: you should not turn on the external circulation. Instead, you can occasionally switch to external circulation to let in some fresh air. If you're in a traffic jam, you should turn on the internal circulation.

What maintenance is needed for a car at 20,000 kilometers?

Maintenance at 20,000 kilometers is typically the third maintenance for a car, which is a major service. The routine items for the third car maintenance include the following: 1. Oil and oil filter replacement: Changing the oil and oil filter is essential. Under the harsh conditions of high temperature and high pressure inside the engine, the shelf life of oil is significantly shortened, and its performance greatly declines. Over time, it fails to protect the engine. The oil filter prevents impurities from mixing into the oil, which can cause oxidation, leading to the formation of sludge and clogging the oil passages. Both the oil and oil filter should be replaced simultaneously. 2. Air filter and cabin air filter: The air filter needs to be replaced at this stage. If it wasn't replaced during the 10,000-kilometer maintenance, it must be replaced at the 20,000-kilometer service. The air filter prevents dust and particles from being sucked into the engine during the intake process. If the filter is not cleaned regularly, it can lead to dust entering the engine, causing abnormal wear on the cylinder walls. 3. Spark plugs: If the car uses standard material spark plugs, preparations should be made to replace them at 20,000 kilometers. Spark plugs directly affect the engine's acceleration performance and fuel consumption. When you feel a lack of engine power while driving, maintenance should be performed. The lifespan of spark plugs varies depending on the material.

Is 7 liters per 100 kilometers considered high fuel consumption?

Not particularly fuel-consuming, as the basic fuel consumption for most cars ranges from 6 to 8 liters. However, exceeding 7.5 liters is considered relatively high fuel consumption. The term 'liters per 100 kilometers' refers to the amount of fuel a vehicle consumes when traveling 100 kilometers at a certain speed on the road. It's a theoretical indicator for vehicles. A car consuming 7 liters per 100 kilometers means it uses 7 liters of gasoline to travel 100 kilometers. Below is relevant information: About gasoline: The English name for gasoline is Gasoline (US)/Petrol (UK). It appears as a transparent, flammable liquid with a distillation range of 30°C to 220°C. Its main components are C5 to C12 aliphatic hydrocarbons and cycloalkanes, along with a certain amount of aromatic hydrocarbons. Gasoline has a high octane number (anti-knock combustion performance) and is classified into different grades based on octane levels, such as 89, 90, 92, 93, 95, 97, and 98. Starting from January 2012, the gasoline grades 90, 93, and 97 were revised to 89, 92, and 95. Gasoline is produced by refining various gasoline components obtained from petroleum refining, including straight-run gasoline components, catalytic cracking gasoline components, and catalytic reforming gasoline components, blended with high-octane components. It is primarily used as fuel for spark-ignition internal combustion engines in automobiles.

What are the reasons for a car door not opening?

There are several reasons why a car door may not open: 1. The remote key is out of battery: If the door won't open when using the remote key, it's likely that the remote key's battery is dead, the car battery is dead, or there is strong signal interference nearby. Generally, remote keys have a hidden mechanical key inside. 2. After obtaining the mechanical key, if you can't find the keyhole on the door, it's because the keyhole is hidden. Manufacturers often hide the keyhole for aesthetic reasons. 3. In this case, you need to look carefully. Usually, there is a decorative piece at the end of the door handle that is about the same size as the key. You can pry it open to access the keyhole.

How Many Years Until a Pickup Truck is Scrapped?

Currently, pickup trucks are still subject to the mandatory scrappage regulation of 15 years or 600,000 kilometers. However, some regions are gradually relaxing this rule, allowing household pickup trucks to operate without a fixed scrappage period. Instead, they are subject to the 600,000-kilometer limit. According to the annual inspection regulations for pickup trucks: new pickups are exempt from inspection for the first 6 years, but owners must visit the vehicle management office every two years to "stamp the paperwork." From years 7 to 15, inspections are required annually, and after 15 years, inspections are required every six months. Pickups that fail inspections or exceed 600,000 kilometers must be scrapped. Below are relevant details: 1. The reality of pickup truck usage: In practice, based on the experiences of domestic pickup owners, mechanical wear and tear after 5-8 years of use leads to sharply rising maintenance costs, increased fuel consumption, and significant depreciation. Additionally, the expense of biannual inspections after 15 years often becomes unsustainable for many owners, prompting them to replace their vehicles within 5-10 years. 2. Factors affecting the used pickup market: A major obstacle to the growth of the used pickup market is the "15-year mandatory scrappage" policy. However, a nationwide trend in the automotive industry is the removal of restrictions on the cross-regional transfer of used vehicles. Cities such as Taiyuan, Datong, Dalian, and Yichang have already issued policies to lift these restrictions, with plans to further stimulate the used vehicle market. For used vehicle dealerships selling pickups, the value-added tax policy for second-hand goods applies, with a reduced rate of 2% (originally 3%).

What are the effects of a significant shortage of coolant?

Coolant plays a cooling role in the car engine. The effects of a significant shortage of coolant are as follows: 1. In cold climates, a significant shortage of coolant can cause the engine or radiator to freeze and crack, leading to engine failure. 2. It affects the radiator's heat dissipation efficiency, preventing normal circulation and making the radiator prone to damage. 3. Coolant effectively maintains the engine within its normal operating temperature, protecting the engine. A significant shortage of coolant reduces the cooling system's effectiveness, causing the engine to overheat. In severe cases, this can lead to engine burn-out.
