What's with the oil injection of lamps?

Question 1: What is the reason for the failure light of the fuel injection system? ? Is the water temperature normal? It may be that the injector is faulty!

For details of Bo Yue, please consult newcar.xcar/79/. Aika Automobile.

Question 2: The detection method of the fuel injector can connect the LED test lamp to the two jacks of the fuel injector plug and turn on the ignition switch. (1) Start the engine. If the LED light is still off, it means that the C and E poles of the triode are open. (2) When starting the engine, the LED light will flash, indicating that the sensor and the computer are good. (3) If the LED light is always on, it means that transistors C and E are extremely short.

Question 3: The fuel injection fault light of my car is always on. What happened? How great will the impact be? First, there is dirty gambling in the oil circuit; Second, there is something wrong with the line.

Question 4: What does the automobile instrument light epc mean? EPC = electronic power control (full name of engine electronic stability system). Many people also call it the electronic throttle.

The system consists of some sensors, controllers and other components. When the sensor fails or senses an abnormal situation, the control system will take corresponding measures according to the set program.

For example, when we accelerate, the control unit senses that the throttle is on. At this time, due to the failure of the brake light switch itself, the control unit receives the brake signal from the brake light switch. According to the program, the control unit will reduce the fuel injection time and reduce the power output of the engine. But at this time, the control unit also received the throttle acceleration request signal, and the computer thought that these two signals were contradictory. When the control unit cannot accurately determine the cause of the fault, it will first light the EPC lamp and give an alarm to remind the user to check. From this point of view, EPC lights are somewhat similar to the common fault warning lights or engine "check" lights in American cars.

EPC indicator lights are more common in the public. After the key door is opened, the vehicle starts self-inspection, and the EPC indicator light will light up for a few seconds and then go out. If the vehicle does not go out after starting, it means that the mechanical and electronic system of the vehicle has failed. Generally speaking, EPC lights have two possibilities. First, the throttle is dirty and needs cleaning. In another case, the brake light is not on, so it is necessary to check the brake switch and wiring.

Also, due to the oil problem, the EPC fault light will also light up. The EPC light of Volkswagen shows that there is something wrong with the vehicle. It is recommended to go to the 4s shop for inspection as soon as possible.

Question 5: What does the fuel injector light on the dashboard V in Turin mean? There is something wrong with the important parts of the engine. Go to the garage to check if there is anything wrong with the car and ask the car master. 4S shop professional technician, 10 minutes to solve.

Question 6: Is the fuel injection uv lamp a printing lamp? Sankun UV lamp answers for you: There are many kinds of UV lamps.

Generally, ultraviolet lamps can be classified according to the energy (W/CM) generated by ultraviolet lamps per centimeter. Commercial UV lamps can be divided into 80, 100, 120, 150 and 240W/CM. The relationship between ultraviolet energy output and curing speed is usually not linear. The relationship between them depends on many factors, such as coating, substrate, reflector, geometry and the overall efficiency of ultraviolet lamp. The sensitivity of pigment material to heat, the thickness of pigment and coating film will affect the efficiency of UV lamp. The ultraviolet band covers the range of 100-400 nm. However, since UV-cured coatings are usually active at 200-450NM, commercial UV-cured lamps are also designed around this range in order to generate high UV intensity in this area.

At present, the commonly used curing UV lamps mainly include mercury vapor lamps, metal halide lamps, xenon lamps, electrodeless lamps and new UV LED lamps. From the structure of UV lamp, it can be divided into two different types of UV lamp systems, namely electrode lamp (arc lamp) and electrodeless lamp (electrodeless lamp).

1, metal halide lamp

In order to change and adjust the output spectrum and get a more suitable ultraviolet lamp for specific purposes, other materials can be added to the lamp tube. When metal halides such as iodide of aluminum, germanium, magnesium, thallium and other metals are added to mercury, the emitted wavelength will shift to the long wavelength direction. For example, when magnesium iodide is used, magnesium outputs spectral lines of 280NM, 3 10NM and 385, which can improve the curing rate.

For example, the high-pressure mercury lamp filled with ferrous iodide, because the lamp is filled with different amounts of ferrous iodide, obtains an ideal spectral distribution, enhances the radiation energy in the ultraviolet region, and is 3-4 times the energy output of the high-pressure mercury lamp. This ultraviolet lamp is based on strong ultraviolet high-pressure mercury lamp, and metal halide is added to enhance its radiation in the effective spectrum of 350nm-450nm. Suitable for dry film, wet film, green solder mask exposure and ultraviolet ink curing. The biggest feature of this lamp is its high ultraviolet intensity.

2. Mercury vapor lamp.

At present, the most commonly used ultraviolet lamps are mercury vapor lamps, which are divided into three types: low-pressure mercury lamps (10- 100 Pa), medium-pressure mercury lamps (~ 100000 Pa) and high-pressure mercury lamps (100000 Pa). It should be pointed out that high, medium and low pressure mercury lamps are defined according to international common standards, which are different from domestic terms. Early UV curing processes used low pressure to cure styrene-containing polyester. Because the output power of this lamp source is very small, it was quickly replaced by medium pressure mercury lamp. In China, the above-mentioned medium-pressure mercury lamp is generally called high-pressure mercury lamp. The tube of mercury vapor lamp is a sealed transparent quartz tube with different lengths (longest 120m), which is filled with mercury. Electrodes are generally made of tungsten and are located at both ends. When an electric current passes between two electrodes, an arc will be generated.

Although timeliness is expensive, all mercury vapor tubes used for ultraviolet polymerization are manufactured timely. The main reason is that there are three important properties that are very suitable for making ultraviolet tubes: (1) transparent to ultraviolet rays, and it does not absorb ultraviolet rays or rarely absorbs them; (2) It is a poor conductor of heat; (3) Low thermal expansion coefficient, timely purity and other trace compounds will affect the emission characteristics of the lamp. The lamp tube is a fused quartz tube with a wall thickness of about 1MM, an outer diameter of 20 ~ 25 mm, and a total length of 2 m. The electrode layout is complicated (electron emitter, pedestal, conductor, etc.). ) sealed at both ends of quartz tube, which contains mercury and starting gas for emitting energy, usually argon.

When the lamp is energized, an arc is generated between the two poles. With the increase of the voltage between electrodes, the gas temperature rises, which makes mercury evaporate, produces mercury vapor arc and emits characteristic ultraviolet light. At full power, the lamp also emits visible light and some infrared light (IR).

Arc lamps need several minutes of preheating time (ranging from 2 to 10 minutes) to achieve complete spectral output, because mercury must be completely vaporized in the quartz tube. In the initial preheating stage, the input power is more consumed in the preheating of the electrode parts of the lamp, and finally all the mercury in the tube is vaporized. So the long induction period is one of the disadvantages of this lamp. In addition, if the power is suddenly cut off at work, the mercury will condense quickly and it is difficult to restart immediately. Heavy heat load also requires cooling time. Usually it needs to be cooled for a period of time (15-20MIN) after shutdown, and then it can be started again. Therefore, arc lamps should be equipped with mechanical or electronic shutters to prevent high ... >:>

Question 7: Iveco engine flamed out when refueling the valve, and the dashboard showed what caused the fuel injection failure. The oil-gas mixture is uneven, the combustion is insufficient, and it is easy to turn off. The fault light is an engine fault light, right? It is also possible that the oil product is not good or the nozzle oil path is blocked by gum, which affects the combustion. Mufu multichannel tablets, a fuel additive, are recommended to help optimize fuel and promote full combustion.

Question 8: What do you mean the battery light on the dashboard is on? This may be a small problem, which is caused by the belt ringing some time ago.

The belt ring may be due to the aging and loosening of the belt, which led to insufficient power generation in the car for a while, resulting in a serious battery shortage today. Although the gasoline locomotive can be started by electricity, the current EFI vehicle can not be started under very serious circumstances, because the generator is insufficient to generate electricity and the battery is dead, which leads to the failure of many parts of the oil pump and injector. Measure the power output of the generator, charge the battery, replace the belt when it is aging, and solve it.
