Video 63 Dạy Sửa Xe: Hệ Thống Phun Xăng Điện Tử Trên Xe Máy Phần 1 | Motorcycles TV

Hello everyone, you are watching MOTO CYCLE TV Today I'm going to make a video for you guys who like and subscribe to MOTO CYCLE TV and ask me to make a video about motorbike power For Honda it's called BZM-FI For Yamaha it's called EMZ-FI All of these technical terms, I put them aside I call it electronic fan on the motorbike The electronic fan technology on the motorbike has been around since 2010 But not many people have access to it and not many schools have access to it With the technology we have now it's quite convenient so you guys can learn a lot With the knowledge I've gained through my work and study I'll try to share it with you guys According to my knowledge there are some things I've learned that may not be true for you or may be different from what you've learned or what you know I hope you guys can sympathize with me Besides that, I'll try to compare what I've learned to the reality of each motorbike as well as the information of motorbike factories and vocational schools I'll try to update it to guide you guys In today's main part On my desk, you can see I'm putting 2 watches This is a VOM watch This is the VOM watch I usually use in the video clips This is the MST electronic watch This watch uses a battery I have a battery here I'll put it here There's a story like this I've seen one of my VFI teachers picking up a customer The customer asked Why do I see in the factory that the customer uses a special machine to plug it into the computer and it shows a hole I saw my VFI teacher holding that watch and it was even more complicated than this watch Can you fix this? To be honest for electronic technology this machine is a support to help us work faster to reduce the workload We don't have to remember the error code or the voltage It can help us predict the disease faster and more effectively It also makes us more professional when the customer sees that this guy uses a modern technology This only helps the appearance and speed But there are things that this machine can't do For example, measuring the voltage This machine can't do that It only knows how bad it is but how bad it is and how to fix it This machine can't do that Only this machine can do that I don't deny the benefits of this machine I'm very proud that this is one of the Vietnamese products This software has Vietnamese I've seen it in Indonesia Malaysia Thailand They are still using this machine made by Vietnamese I'm proud of that But not everyone can invest 8 million 10 million to buy a machine like this upgrade software add signal cables connect computers Not everyone can afford this machine But with this VOM you can buy it So I will try I will guide you with the simplest tools You can do it manually Then I will let you verify with this machine so that you have a close interaction You can use high-tech machines You can use laptops You can use computers You can use high-tech machines You can do it Let's talk about the machine I will talk about the problem Currently BGMFI technology is an electronic fan technology It is operated based on the principle that the input signal from the sensors provides the parameters for the IC or ECM ECU VET3 is the MIU It is called IC The signals of the sensors are sent to the IC when we turn on the switch For example This IC is a center processor A guy is sitting at work When a day starts 8am I turn on the switch This guy sits at the desk and asks for data from the warehouse from the business room from the sales room He needs to know how many goods the warehouse has He needs to know how many orders were received He needs to know how many people are there How many trucks are there He will arrange the order distribution How many boxes are delivered to Saigon, Hanoi, Da Nang How many boxes are delivered to this unit That is the signal that will be sent to the IC to emit the electric current Then it sends the signal to the fan It sends all the signals to the center It sends the signal to the brain The brain is like a monitoring unit It knows which part is working and which part is not This is the brain The brain is here This is a pin I took it out There are two sensors on this pin One sensor is the position of the fan to supply signals to the IC to understand that the fan is closed There is no wind going in The IC understands that the fan is closed It will start and it will receive the signal to change the electric current inside when I increase the fan It will know the position is open It will give more fan It will give more work Then it also controls the Valve Guarantee This system has interaction It receives signals from the sensors to understand the temperature of the engine The pressure of the fuel The temperature of the air The temperature of the engine The position of the CKB sensor It will start For example, all signals are safe It will start If for some reason this fan is stuck It means it is stuck If you want to start this fan needs to go to the front It can't start It understands that the value of electricity is high This is how it works These are normal ICs These ICs are from Accelerator These ICs are from Honda Clip 110 These ICs have quite a lot of wires But it's still a normal IC It's still a normal IC Even though it has more functions such as AC, fan, etc It's still a normal IC It's not a big one It's smaller than this one But inside this one There are a lot of complicated electronics It has a software system RAM, ROM, etc It's in a small box It's small It's smaller than half of Exciter and 2.3 of Clix 110 Even though it's Airblade 110 2011 I'll talk about the function of BCMFI You guys need to remember I'll talk about it later DLC Cali Mu BCMFI SCF FLR EEPROM EVAP So that it can recognize the position of the open position of the exhaust pipe, whether it is high or low, large or small, whether the hole is wide or narrow. MAP sensors the pressure inside the engine. IAT is a sensor that measures the temperature of the air intake. For example, if the car is running in the desert, the temperature will be different from that of the car running in the desert. The ambient temperature is 80-70°C, which is different from the ambient temperature of 2°C or 0°C. It's completely different. The IC will automatically receive that signal, so it gives the amount of fuel more or less, depending on this. CO2 is the exhaust gas. But my wife often calls it an oxygen sensor. Although it is CO2, it is often called an oxygen sensor because it is located next to the exhaust pipe. ECT, E-C-T, E-O-T, E-C-T, E-O-T, is the temperature sensor of the engine. So why does it have two names? One name is that the car has no coolant, and the other name is that it has coolant. That's all. VF is the speed sensor, which is the speedometer. There are some cars that don't have a clock in front of them. If you look at the Future 125 Fi, it doesn't have it. Or the E-Blade doesn't have it. The speed sensor is located in the rear wheel, in the transmission. So this is VF. IACV and IAC are Van Guaranteed Automatic. Yamaha calls it differently, Honda calls it differently. CKB is the fire extinguisher. ACG is the gear system. The gear is the gear that you press and it doesn't make a sound. It doesn't make a sound like the Airblade. S-O-L-V is the control valve. It's temporary or guaranteed. ABS is the electronic control system. The anti-slip system. I-D, I-Clean-Stop is a temporary stop. When you stop the car at a certain temperature, I'll talk about this later. What's the temperature? When it detects the VF, which is the speed sensor, it will automatically stop the engine to save fuel. This is the I-Clean-Stop system on new cars. Some basic words you should remember. I have a car here. I have categorized them. CKB, MAF, IAT, TB, ACT, OC. Turn-off is the key. The initial sensor is the car's steering sensor. When the BZM-FI falls, the car will automatically turn off. And when you pull it up, it takes a few seconds to recover and open the key again, then it will explode. That's the initial sensor. These sensors are the initial sensors for the I-C. The TB sensor will not explode if it is too high. When it is broken, it will explode, but it will not run. The CKB sensor may not report an error, but it will not explode if there is an accident. I will show you later on the car. Although these sensors may be broken, they still report an error. But sometimes there are sensors that are broken but do not report an error, and we have to read the manual error or use a specialized error reading machine to read the status of the sensor. So there is no need for the FI error to appear on the watch. These are the sensors that provide the initial signal. I'm just talking about the start-up process. And when the car is ready to start, the I-C and these sensors still communicate with each other. For example, the TB is high or low, which means the gas is high or low. There will be a power supply for the I-C and the I-C will return the signal to it. These two will go back and forth when the car starts. And when the car starts, all these sensors provide signals. For example, when a company is operating, these sensors provide signals to this car. After that, this car will receive all the safety signals and provide signals to these sensors. This includes the gas pump, which will control the gas pump to operate. The mobile phone will control the buzzy, and the fan will do the job of blowing the gas. IACV is the electronic fan. MU is the FI signal. DLC is the unique signal. The I-C will provide these signals to the I-C. What does DLC do? When you plug it in, it will understand. When you read the manual, it will understand. This is the concept of BCMFI. Now I'm going to get in the car. The FI document will be based on the original document from the company. All the parameters are from the company. Everything is from the company. So don't worry, the accuracy is OK. Now I'm going to get in the car. The first car I'm going to work with is the Honda Airblade 110, version 2010-2011. This is the car. I'm going to put it in the car and show it to you. I've shown you the details of the car. And I've shown you how the FI electronic fan works on the car. Now I'm going to put it in the car. This is the Honda Airblade 110, version 2011-2012. I remember correctly, this car is 2011-2012. Now I'm going to use the Honda document. This is the version 2010-2011. This is the document of the Honda systems. This document contains the FI electronic fan of the Airblade Airblade 2011-2011. In the Honda document, I usually work based on the exact parameters of the company. As well as the data of the company. So it will be easier to operate. This is the electronic system of the Honda Airblade 2010-2011. This version is temporarily called the FI version 2. Because the FI version 1 is the 209 generation. The FI version 2 is the 209 generation. As you can see, the position of the FI version 2 is clearly indicated. The power switch is located next to the mask. The R-Level is activated. The R-Level is 9. The D-L-C is the single coil. The I-C-M is the IC. It's right here. The fuel pump is right here. The ECT is right here. The AC is right here. The OC is right here. The fire roll is right here. The TV is right here. The fire roll is the motor. The TV is the position of the gas pump. The V-S is the speed. The I-F-C is the I-A-C-V. The C-K-B is the speed. That's it. This is the manual of the electronic system. It starts from the center position in the saddle. It leads to many terminals. The center position is the ECM. It leads to many different terminals. Let's go through it. The saddle is just like that. It is also clearly written in this. Find the FI fault. Check the circuit. The fault of the light bulb is very much. Let's see. The fault of the light bulb is very much. That's it. That's all. Now, let's see the manual. This is the gas pump. IAT and MAP sensors These sensors are temperature, pressure, and gas pressure In this version, there is no sensor This is a VIN Guarantee This is a VIN Guarantee This VIN Guarantee This is a TPI sensor TPI is a gas pressure sensor I showed you on the gas pump This TPI sensor works based on increasing and decreasing gas This is a MAP sensor This is a MAP sensor This is a IAT sensor This is a temperature sensor For temperature, you have a ICT sensor or EOT sensor temperature sensor And this is a OC sensor For the temperature sensor For the oxygen The speed sensor is located at the back of the car There is a gap here, it goes out to the back of the car That's called the VF sensor I go to the front This is the position of the fuel pump The fuel pump and fuel tank This is the ECM-ECU-VUIC It's the EC It's the central control unit For Vespa, it's called Miu For Honda, it's called ECM For Yamaha, it's called ECU It's also called the EC Many people still argue with me Why is it called the EC? This is the EC But the name is different It has more functions It receives input signals And output signals For motor parts It's actually the EC But it has more functions It's called the ECM-ECU-VUIC It's actually the EC This is the cable from the fuel pump This car uses a 3-phase charger It's called the 3-phase bridge 3 yellow cables from the fuel pump I will show you how to use it There's a blue cable from the fuel pump And a white cable from the EC This car has a counter-clockwise function When you put it counterclockwise, it won't move This is the 3-phase charger It's called the 3-phase charger This is the fuel tank It has a label on it The other control unit To prove we have a 10 Amm of current This is the control unit This is the ignition relay The немного The nickname of BZM-FI and Yamaha One is near the tank, the other one is far from the tank In fact, on the Honda car, the unique jack is always red I usually see it always red This is the unique manual jack Or this jack can be plugged in The unique way I will guide in the next part Now I'm just testing what FE is What is FI, what is FE It depends on what you call I, for example, in Vietnam, call it FE electric milk Just call it FE Its full name is Fuel Injector Let's skip this part Some of you know a lot about fuel injection Some of you don't know You can see here You can see a lot of wires In fact, it is a traffic jam It's a car remote It's a car remote, not an EC Some of you don't know about BCM-FI You think this is an EC It's wrong There are a lot of wires In fact, here I notice There is an orange wire, there is a green wire It's a signal wire In fact, the car remote is a signal light chip It's a car remote This is a motor This is how the FE system works When we turn on the key The fuel pump is working You hear the pumping sound The fuel pump is working When we start the engine The fuel pump will work Back to the signal from the EC And the fire system On the clock When we turn on the ignition, the light will be on and when we turn it off, the light will be off And we will turn the ignition on and off Then the car will run normally Now I will show you an example I will show you an example Here, I will take out the IAT I will take out the temperature sensor I will put it out I will try it I will turn off the ignition Now I will turn on the ignition When I turn on the ignition, the light will be on Now I will test the ignition Here, how many errors? 4, 5, 6, 7, 8, 9 1, 2, 3, 4, 5, 6, 7, 8, 9 9 fast errors Because of these 9 fast errors I will understand the temperature sensor of the IAT You can search on Google or in car repair forums Or in any store You can ask this question This is the temperature sensor of the IAT Then I plug in the temperature sensor When I plug in immediately The EC Or ECM Let's just say EC EC doesn't understand The light is still on Then I will turn off the ignition When I turn on the ignition, the light will be off But actually In the memory of this EC It still has the history error That means In the electronic system There will always be 2 errors The history error That error has been fixed And the current error There is no error in this car And the history error has been deleted Now I have shown you the 9 fast errors You will be able to see the 10 Now I take off the seal I take off the seal Now when I take it off, I haven't set it up yet Then the EC still doesn't understand Because there is no signal It is being missed I turn off the key I open it up It will start to report errors 1 slow 2 fast 1 slow and 2 fast I continue to read 1 slow 2 fast So it's just the 12th error That means it's a seal error Error number 12 Now I put the seal in And I try another band I try another band I pull out the warranty band Fast verification Turn off the key Open the key again And no error What does this prove? When the car is broken There are some cases where the warranty is lost Can't park Can't park but can't run Many problems I wonder There is a problem with this car But I don't understand I don't know if it's a mistake Actually, it's an e-car When it doesn't explode Can't run These errors are mostly in the e-system Then you just report accurately That is the fault of the e-system And I will start to die Actually, it's not a mistake It will also report on the e-system Or report the number like Yamaha Report the number of errors There are some errors that will not report And those errors need to be There are specialized machines Plugged into this DLC jack Or I will read the manual error I will guide you later I will guide in another part Today I just let you know Then here I will prove There is another error CKB sensor I took it out And now I don't ban it So it still doesn't report errors Can't park But it still doesn't report errors Then I proved it to you Is the operation of the e-system When there is an error Light warning Fast and slow And I will show you I will show you the errors Not reported on the light But I will call the error manually I will save this for the next lesson My lesson today About the e-system ECMFI Also known as EMZFI On Yamaha After this I will summarize I will call it the e-system And each brand will have their own name And I know the name I call that name And today I have agreed with you The name is already called I hope that the next chain will not receive The comments of some friends The name is this Just a habit Like I said ECMFI And other names related to ECMFI Thank you for watching Today's video See you in the next lesson Goodbye
