China 5 and China 6 standards refer to vehicle exhaust emission standards. The introduction to China 5 emission standards is as follows: China 5 Emission Standard: The carbon monoxide emitted per kilometer driven by a vehicle must not exceed 1000 milligrams; the non-methane hydrocarbons emitted per kilometer driven must not exceed 68 milligrams; the nitrogen oxides emitted per kilometer driven must not exceed 60 milligrams; the PM fine particulate matter emitted per kilometer driven must not exceed 4.5 milligrams. China 6 Emission Standard: The carbon monoxide emitted per kilometer driven by a vehicle is 500 milligrams; the nitrogen oxides emitted per kilometer driven is 35 milligrams; the fine particulate matter emitted per kilometer driven is 3 milligrams; the non-methane hydrocarbons emitted per kilometer driven is 35 milligrams.

What is the purpose of the sponge inside the fender?

The purpose of the sponge inside the fender is to absorb moisture expelled from the interior of the car, which is then evaporated. Below is an introduction to the car fender: 1. Definition: The fender, also known as the wing panel, is the outer body panel that covers the wheels. Depending on the installation position, it is divided into the front fender and the rear fender. 2. Function: Utilizing fluid dynamics, it reduces the drag coefficient, making the car drive more smoothly. The front fender is installed at the front wheel, and because the front wheel has a steering function, it must ensure the maximum limit space when the front wheel turns. Therefore, designers use the "wheel jump diagram" to verify the design dimensions of the fender based on the selected tire model size. The rear fender does not have the problem of wheel rotation rubbing, but for aerodynamic considerations, the rear fender is slightly arched outward.

Where is the car computer motherboard located?

In a car, the computer is also known as the Engine Control Unit (ECU), or Electronic Control Unit (ECU). It processes simple electronic signals and performs basic calculations using simple logic gates and integrated circuit principles. It receives data from various sensors throughout the vehicle, processes the information, and sends output signals to the engine to control its operation. Related information about car horns is as follows: 1. Introduction: The horn is the sound signal device of a car. During driving, the driver uses it as needed or required to issue necessary sound signals to warn pedestrians and alert other vehicles, ensuring traffic safety. It is also used for urging movement and conveying signals. 2. Classification: Car horns are divided into air horns and electric horns based on their sound power; they are categorized into cylindrical, spiral, and disc types based on their shape; and they are classified into high-pitch and low-pitch horns based on their sound frequency.

What is the reason for the trunk not locking when remotely locking the car?

Here are the reasons why the trunk does not lock when remotely locking the car: 1. Use of overly stiff spring rods: Overly stiff spring rods are used to allow the rear hatch to automatically rise after pressing the opening switch. 2. Component matching issue: The closing limit rubber block does not match the locking mechanism properly. 3. Wiring fault: There is a problem with the trunk adjustment wiring. 4. Support rod failure: There is an issue with the trunk hydraulic support rod. Faced with the situation where the trunk cannot be closed, most car owners can only try to close it with more force. If it is indeed caused by the above reasons, using more force will only increase the damage. The correct approach should be to drive the vehicle to a repair shop for inspection. If the door cannot be locked, a simpler method is to use the spare mechanical key to lock it.
