What does a 'quilted truck' mean?

A 'quilted truck' refers to a high-sided truck with quilts wrapped around its perimeter. After loading the cargo, the goods are further covered with quilts. This type of truck is suitable for transporting frozen goods, seafood, and fruits, primarily to maintain temperature at a lower cost compared to refrigerated trucks. Refrigerated trucks, on the other hand, are enclosed box-type vehicles designed for transporting frozen foods, dairy products, vegetables, fruits, vaccines, and medicines. Below is an introduction to refrigerated trucks: 1. The role of refrigerated trucks: The advent of refrigerated trucks has enabled many perishable foods such as fruits, meats, and frozen desserts to be transported over long distances under frozen or fresh-keeping conditions. 2. Classification of refrigerated trucks: Refrigerated trucks are divided into two main categories: refrigerated road vehicles and refrigerated railway cars. Refrigerated road vehicles are primarily used for intra-city food transportation, such as delivering frozen desserts, fresh fruits, fish, and meat from factories to various stores, and sometimes for medium to short-distance intercity refrigerated transport. Refrigerated railway cars undertake medium to long-distance refrigerated food transportation tasks. 3. Refrigeration methods of refrigerated trucks: Some refrigerated trucks use ice refrigeration, which involves placing large blocks of ice mixed with salt inside the truck's compartment to maintain an internal temperature below -8°C. However, this refrigeration method can only sustain for a limited period. For long-distance refrigerated transport, it is necessary to establish a series of ice and salt replenishment stations along the transportation route to continuously supply the refrigerated truck with ice, ensuring the refrigeration effect is maintained.

Is Audi a German Car?

Audi is a German car. It is an automobile manufacturer from Germany, and Audi has a variety of sedan and SUV models. Here is an introduction to the Audi A8: 1. The length, width, and height of the Audi A8 are 5302 millimeters, 1945 millimeters, and 1483 millimeters respectively, with a wheelbase of 3128 millimeters. 2. The A8 is equipped with two types of engines: one is a low-power version of the 3.0-liter turbocharged engine, and the other is a high-power version of the 3.0-liter turbocharged engine. 3. The low-power version of the 3.0-liter turbocharged engine has a maximum power of 210 kW and a maximum torque of 450 Nm. The engine's maximum power speed ranges from 4500 to 6400 rpm, and the maximum torque speed ranges from 1340 to 4430 rpm. This engine is equipped with a 48V mild hybrid system and direct fuel injection technology, and it uses an aluminum alloy cylinder head and block. 4. The high-power version of the 3.0-liter turbocharged engine has a maximum power of 250 kW and a maximum torque of 500 Nm. The engine's maximum power speed ranges from 5000 to 6400 rpm, and the maximum torque speed ranges from 1370 to 4500 rpm. This engine is equipped with a 48V mild hybrid system and direct fuel injection technology, and it uses an aluminum alloy cylinder head and block. 5. Both engines are paired with an 8-speed automatic transmission (8AT), which improves the car's shifting smoothness and fuel economy.

Can engine oil brands be switched?

It is possible to switch brands, but it is important to note that the type of engine oil should not be changed. For example, if the vehicle previously used fully synthetic oil, it is essential to continue using fully synthetic oil after switching brands. This helps minimize the engine's adaptation time and ensures optimal engine performance. Engine oils are categorized into three types: the first is conventional mineral oil, the second is semi-synthetic oil, and the third is fully synthetic oil. Conventional mineral oil should be replaced every 5,000 kilometers or six months. Semi-synthetic oil should be replaced every 7,500 kilometers or nine months, and fully synthetic oil should be replaced every 10,000 kilometers or one year. When changing the engine oil, the oil filter should also be replaced simultaneously.

Can regular engine oil burn?

Engine oil itself does not burn. Without any attached materials, it won't ignite even when exposed to an open flame. However, if flammable items are contaminated with engine oil, they can easily catch fire. For safety reasons, it's best to avoid exposing engine oil to open flames. The engine oil inside a vehicle won't burn because combustion in the engine cylinder won't ignite the oil. In current internal combustion engines, diesel engines rely on piston compression for ignition, while gasoline engines use spark plugs. However, both require fuel combustion to generate power. After fuel ignition, piston rings separate the high-temperature, high-pressure combustion gases in the cylinder from the engine oil passages, preventing oil from entering the combustion chamber.

Can Engine Oil Be Ignited by a Lighter?

No, engine oil requires a combustible material to ignite. Under normal circumstances, engine oil will not burn when exposed to an open flame without any attached combustible material. However, engine oil itself is flammable, so if there is an attached combustible material carrying an open flame, it can catch fire. Therefore, for safety reasons, it is best to avoid exposing engine oil to open flames. Additionally, storage should be handled with care, and contact between engine oil and open flames should be minimized. The boiling point of engine oil is generally around 150°C, and its flash point should be 20–30°C higher than its operating temperature. The choice of engine oil should be based on the operating temperature, as not all vehicle models operate under the same conditions.

Reasons for the Sudden Failure of Three Side Windows to Roll Up or Down

This situation is caused by damage to the power window regulator on the driver's side; the power window motor enters an overheat protection state in a short period. Below is more information regarding electric windows: 1. Maintenance Process: The window glass should be kept clean. When rolling the window up or down to the top or bottom, release the button promptly. Regularly check the aging degree of the window glass seal strips and clean them periodically. 2. Solutions: Promptly visit a car 4S store or repair shop to inspect the power window regulator. Most failures to roll up or down are due to mechanical jamming, which can be resolved by cleaning the guide rails and applying some lubricating oil. If the issue is caused by aging or deformation of the glass seal strips, new sealing strips need to be replaced. If the problem is simply due to excessive dirt, cleaning will suffice.
