What is the function of the air pump？ 0

The role of the air pump is to let the engine to send the air to the three-way catalytic converter in the cold car, so as to use the exhaust gas into the oxygen in the air to achieve secondary combustion, improve the temperature of the three-way catalytic converter, so that the three-way catalytic converter can enter the working temperature as soon as possible, reduce the harmful substances in the exhaust gas, and play a role in environmental protection.

Air pump is mainly used for pumping, sewage treatment, electroplating drum, biogas tank aeration, tunnel ventilation, etc.

air pump The "air pump", a device that removes air from an enclosed space or adds air from an enclosed space. Air pump is mainly divided into electric gas pump and manual air pump, foot air pump. Electric gas pump. The air pump powered by electricity presses the air through the power to generate air pressure.

The working principle of the air pump is: the engine drives the crankshaft of the air pump through two triangular belts, so as to drive the piston to pump, and the gas is imported into the air storage tube through the guide pipe. On the other hand, the gas storage cylinder introduces the gas in the gas storage cylinder into the pressure regulating valve fixed on the gas pump through a guide pipe, so as to control the air pressure in the gas storage cylinder. When the pressure in the storage cylinder does not reach the pressure set by the regulating valve, the gas entering the regulating valve from the reservoir cannot open the pressure in the reservoir reaches the pressure, opening the regulating valve from the reservoir and the entering pump is connected with the regulating valve Airway, and through the airway control of the air pump inlet often open, so that the air pump empty load operation, to achieve the purpose of reducing power loss, protect the air pump. When the pressure in the storage cylinder is lower than the pressure set by the regulating valve due to the loss, the valve in the regulating valve is turned back by the return spring, disconnecting the control path of the gas pump, and the gas pump starts to pump again.The secondary air pump is broken and affects what

The influence of the secondary air pump is unstable and the mixture is too thin.

details are as follows:

1. check the intake air flowmeter, there is a blockage, or the line is damaged, then will lead to mixed too thin, maintenance method is to clean the flowmeter, or use tape to repair the damaged line, serious, it will need to replace the components.

2.It is also possible that the oxygen sensor has a problem, if the oxygen sensor has carbon deposition, the normal cleaning is ok, if the sensor is seriously damaged, it is necessary to replace the oxygen sensor.

3.the engine carbon deposition is too much, then it is necessary to immediately clean the oil circuit, or add fuel additives in the tank to clean up, the nozzle and spark plug, but also to timely clean, in order not to produce a large amount of carbon deposition, the owner must regularly clean these parts.

4.the secondary air fracture, go to the 4s shop to replace the new.

5.the cathode line is wrong, go to the 4s shop to reinstall the cathode line.

6.the secondary injection valve is damaged, mainly due to insufficient closing force; debris falls between the valve seat and the gate; the valve sealing surface is not processed or damaged; need to go to 4s shop to repair the secondary injection valve.

7.the abandoned cylinder head channel is blocked, so it is recommended to open the cylinder head for cleaning.

8, the vacuum tube rupture, need to check the cooling system, or the exhaust system blockage, the vacuum pipe leakage. Replace it with a new vacuum tube.

The role of the secondary air pump, is the engine in cold car to ternary catalytic converter into the air, in order to use the exhaust gas encounter oxygen contained in the air for secondary combustion to improve the temperature of the ternary catalytic converter, can make the ternary catalytic converter temperature as soon as possible and enter the working state, can reduce the emissions of harmful substances in the exhaust gas, plays the role of environmental protection.

What Is an MP5 player for car? 0

An MP5 player is a digital device that can play audio and video that you have downloaded onto it. It differs from MP4 players in that the format of the files that you download does not have to be changed in order to make it work on the device.

MP5 players are devices that work digitally to play audio and video and are updated versions of MP3s and MP4s. There are some important differences compared to earlier versions. The biggest is that the MP5 player can play files without having to reformat them from RM and RMVB format, which many video are in these days. This means that one may download anything without the worry or stress of it not working properly on the device. Another important difference is that the screen is usually larger than the MP3 and MP4 players, providing the user with better video quality.

Car mp5 and Android difference (car mp5 has what strategy

Many cars now use voice control function as a selling point in the trend. In fact, from the perspective of technology application, the implementation is not complicated, and it does not need to increase the hardware cost. In fact, you just need to control the joints.

Now the car voice control function on the market is generally used to control the skylight or wiper, which does not involve the operation endangering personal safety, mainly used to improve the comfort of users and the sense of product technology. Implementation requires several components on the vehicle: voice recognition system (generally the on-board multimedia MP5), vehicle control system (BCM or PEPS) and actuator components (sunroof control module or wiper control motor).

Voice recognition systems are now quite mature, and basically monopolized by several big companies. Car multimedia MP5, in fact, you can see that it is a large screen mobile phone, voice call this operation is basically quite popular, here do not do too much explanation.

Take the skylight, you can say, "I want air."After the speech recognition system recognizes the speech, it will issue a CAN communication message to inform the vehicle control system to open the sunroof. I have written a few articles about CAN communication, and I will not discuss them here.

Vehicle control system

At this time, we needed the BCM to play the field. After receiving the CAN message sent by MP5, we found that the instruction was explained that the skylight opened. Next, we would pass this instruction to the skylight control module. The BCM and the skylight control module are generally connected by the LIN bus. That is, the BCM needs to send a LIN message to the skylight control module, informing the skylight control module to open the skylight. I have also introduced the part of LIN communication, and I will not discuss it here.

execution unit

After the instruction is handed down by the first level, the key is the response execution. After receiving the skylight control module of the LIN message to open the skylight, it is the instruction to open the skylight, which can drive the skylight control motor to open the skylight. Of course, there are some logical control details, such as receiving multiple instructions or instruction conflicts. To put it simply, there is only one executor, and commands can be received multiple, who to listen to. In general, the execution are their own itself. Who responds to, who does not respond to, who can interrupt who, there is a priority problem, even considering the skylight trap. The With the seemingly simple execution parts, the design is not necessarily really simple.

In this way, the car's voice control function seems cool, but it's actually not complicated to implement. In fact, you just need to get through the joints, and then connect the existing modules. It is mainly using the voice recognition system to recognize the control instructions, and then pass through the car bus level, and finally to the execution part response execution.

The Development History and Advantages of Bluetooth Head Unit 6

In the early cars, there was no such thing as a screen. If people wanted to relax and entertain in the car, they could choose to listen to FM radio and play tapes or CDs.

In the 90s of the last world, with the increasing demand for entertainment, people are no longer satisfied with the simple way of entertainment inside the car, hoping to have more abundant electronic equipment available.

At that time, the central control screen launched was still very crude, and neither the liquid crystal display nor the touch screen technology was mature. If a screen with a low resolution is forcibly equipped, it means that the display effect is mediocre, and many physical buttons will be added, and the numerous buttons make it very inconvenient for users to use. The negative feedback from the market also limits the promotion of central control by car companies. screen moves.
