Auto recloser relay control higher voltages or currents by using lower voltages or currents. When a certain voltage or current is applied to both ends of the electromagnetic relay coil, the magnetic flux generated by the coil passes through the magnetic circuit composed of the iron core, the yoke, the armature and the working air gap of the magnetic circuit. Under the action of the magnetic field, the armature is attracted to the pole face of the iron core. Therefore, the normally closed contact of the contact is pushed to be disconnected, and the normally open contact is closed. When the voltage or current at both ends of the coil is less than a certain value, and the mechanical reaction force is greater than the electromagnetic attraction force, the armature will return to the initial state, the normally open contact is disconnected and normally closed contact is on. How To Test Auto Relays？ (1) A simple method for judging the working performance of the relay. Turn on the ignition switch, and then use your ear or stethoscope to listen to the sound of the control relay, or feel the vibration of the relay with your hand. If there is vibration, then the relay is working well, the electrical appliance does not work due to other reasons. Otherwise, the relay is not working properly. You can also unplug the relay for testing, for example, if the air conditioner compressor does not work, you can start the engine, turn on the blower switch and the air conditioner switch. Then unplug the connector of the air conditioner compressor relay to judge. If the sound of the relay action can be heard, the engine speed drops significantly when the relay is unplugged, and the engine speed rises when the relay is inserted, it means that the air conditioner compressor relay and its control circuit are normal. (2) Common failures of relays. Common failure phenomena of relays include coil burnout, inter-turn short circuit or insulation aging, contact ablation, thermal decay, and inability to adjust the initial operating current. ①The relay coil is burnt out. In order to prevent this from happening, if the temperature may exceed 80°C during repair, maintenance and electric welding, the temperature-sensitive relays and electronic control units should be removed. ② Contact ablation. For example, vehicle with 491Q-ME engine, the relay of the air conditioner condenser fan is just below the glass cleaning spray pipe. If the spray pipe is broken, the cleaning fluid will leak to the relay, making the relay normally open contact is corroded and cannot be disconnected, which will lead to the failure of the air conditioner condenser fan to keep running. Therefore, water should be strictly prevented from entering the relay. (3) Try to reduce the contact resistance of the relay contact The contact resistance existing between the contacts of the automotive relay is mainly composed of shrinkage resistance and surface film resistance. The contact resistance of the contact is related to the contact form, material properties and surface processing of the contact. It can be seen that to reduce the contact resistance of the relay contacts, under the condition of a certain contact pressure, it can be started by improving the contact state and improving the contact material. (4) Poor grounding of the ECU may affect the normal operation of the relay As one of the most professional car spares suppliers, we provide automobile air filter, car spares and parts, auto off relay, auto power relay, auto relay block, auto relay switch, pencil coil, etc. For more information, please feel free to contact us!

Automobile fuel supply system is classified according to fuel supply mode: carburetor engine, EFI engine and in cylinder direct injection engine, supply to the cylinders, and make it ignite, burn and expand to do work near the end of compression. Finally, the fuel supply system should also discharge the combustion product exhaust gas into the air. Each part must work flawlessly to achieve expected vehicle performance and reliability. Car fuel supply system has been widely used in automobiles because of its simple structure, convenient use and low cost. However, the main disadvantage of carburetor engine is that the inflation and mixture distribution are not ideal. It has a certain adverse impact on the improvement of engine power, economy and emission. Therefore, modern cars are basically not used. At present, the mainstream is EFI engine and in cylinder direct injection engine. EFI engine uses electronic control device to control the fuel supply process of the engine. According to the number of injectors, EFI engine can be divided into multi-point injection and single point injection. At present, multi-point injection is mostly used. The main principle of multipoint EFI is that the injection process of gasoline fuel is in the intake manifold. If the injector is installed on the intake pipe of each cylinder, gasoline can be injected into multiple cylinders, which forms multipoint injection. The cost of gasoline injection is not only lower, but also less carbon deposition. How Does The Automotive Fuel System Parts Work? The fuel pump sucks the fuel out of the fuel tank, filters out the impurities through the fuel filters and enters the low-pressure fuel chamber of the fuel injection pump. After increasing the fuel pressure, fuel will be transmitted to the fuel injector through the high-pressure fuel pipe. When the fuel pressure reaches a certain value, the fuel injector sprays the fuel into the combustion chamber in the form of mist to form mixed gas and burn. After working, the waste gas will be discharged into the atmosphere through the exhaust device. The task of fuel supply system is to prepare a certain amount and concentration of combustible mixture according to the requirements of various working conditions of the fuel engine, supply it to the cylinder, and make it ignite, burn and expand to do work near the end of compression. Finally, the supply system should also discharge the combustion product - exhaust gas into the atmosphere. How To Wire Automobile Fuel System Parts? Components of automotive fuel supply system consist of fuel tank, fuel pipe, fuel pump, fuel filter, air filter, fuel pressure regulator, fuel injector, intake manifold, exhaust manifold, etc. The task of the fuel supply system of fuel engine is to pump the fuel out of the fuel tank through the fuel pump, via fuel filter which filters the impurities and water in the fuel, then enters the fabricated fuel rail. The engine ECU sends fuel injection signals to the fuel injection nozzle according to the output signals of various sensors of the engine, ejects the fuel from the fuel injectors at a certain pressure, mixes it with the clean air obtained through the air filter in the intake manifold in a certain proportion according to the requirements of various working conditions of the engine, finally enters the cylinder, compresses, works and exhausts in the cylinder, to generate engine power.

The car air filter commonly used in passenger fuel vehicle engines mainly have paper air filter and polyurethane air filter. Paper air filters are made of microporous filter paper treated with resin. The filter paper is porous, loose and folded. They have certain mechanical strength and water resistance with advantages of high filtration efficiency, simple structure, light weight, low cost and convenient maintenance. They are most widely used as vehicle air filters at present. Polyurethane car filter are made of soft, porous and spongy polyurethane with strong adsorption capacity. They have the same advantages of paper air filters, but also have low mechanical strength. What Are the Symptoms of a Bad Air Filters? The auto air filters is a device for removing particulate impurities in the air. If the air contains dust and other impurities, will aggravate the wear of engine parts, so air filter with good performance must be installed into the vehicle. The main requirements of the air filter are high filtration efficiency, low flow resistance and continuous use for a long time without frequent maintenance. In case of damage or blockage, the following phenomena will occur. Acceleration performance decreases and fuel consumption increases. Once the filter element is blocked, there is too much dust and the aperture of the filter paper is blocked, will hinder the passage of air. Then the air intake rate will decrease, the air flow will decrease, and there is not enough air support when the engine burns. Even if the accelerator is pressed deeply, the speed still can not come up, there will be insufficient power and the driving fuel consumption will increase. Moreover, under the strong negative pressure (intake suction) of the engine, the dust, impurities and particles outside the filter element will break through the filter paper and directly enter the cylinder to participate in combustion, even lead to the breakage and rupture of the filter paper. The engine emits black smoke. If the automobile air filter is damaged or not replaced and cleaned for a long time, the dust will directly enter the engine and pass through the throttle. At this time, the particles in the air are like grinding sand, which will cause wear to the throttle. After the throttle is worn, it will sink, reduce the compression ratio and air leakage, resulting in the reduction of engine cylinder pressure, hard to start and low combustion efficiency. The cylinder burns insufficiently, the exhaust pipe emits black smoke and presents a divergent shape, and the air flow has no impulse.

Automotive air conditioning is mainly composed of refrigeration system, heating system, ventilation and air purification system and control system. The principle of automotive air conditioning has four sections. A, The compressor sucks the low-temperature and low-pressure refrigerant gas at the outlet of the evaporator, and compresses it into high-temperature and high-pressure gas and discharges from compressor. B, The high-temperature and high-pressure refrigerant gas enters the condenser and condenses into a liquid, discharges a large amount of heat. C, The refrigerant liquid with high temperature and high pressure increases in volume after passing through the expansion device, the pressure and temperature drop sharply, then discharged from the expansion device in the form of a mist. D, The mist-like refrigerant liquid entering the evaporator, the boiling point of the refrigerant is much lower than the temperature in the evaporator, and the refrigerant liquid evaporates into a gas. Diagram of Air Conditioning System (A/C) The automotive air conditioning refrigeration system consists of a compressor, a condenser, a liquid receiver dryer, an expansion valve, an evaporator and a blower. The components are connected by copper pipes and high-pressure rubber pipes to form a closed system. When the refrigeration system works, the refrigerant circulates in this closed system in different states.

The airbag sensor is the input device of control signal in the SRS system. When the vehicle happens to collides, the airbag sensor detects the intensity signal of the vehicle collision, and inputs the signal into the airbag computer. The airbag computer determines whether to detonate the inflatable element to inflate the airbag according to the signal of the airbag crash sensor. How To Test airbag front sensor? 1) Symptoms of airbag system failure are difficult to diagnose, so diagnostic codes are the most important source of information for troubleshooting. Always check the diagnostic codes before disconnecting the battery. 2) Disconnect the ignition switch during inspection. If the vehicle allows to remove the negative electrode of the battery, it is better to disconnect the power supply. It should be started after removing the negative electrode for 90s or longer. Because the airbag system is equipped with a backup power supply, the airbag may still deploy within 90 seconds after removing the negative terminal of the battery. 3) Even if only a minor collision occurs and the airbags are not deployed, the front airbag pressure sensor and steering wheel cushion should be checked. 4) Do not expose the front airbag impact sensor, center airbag sensor assembly and steering wheel pad directly to hot air and flames. 5) When testing the circuit, a high-impedance multimeter should be used for measurement. 6) The parts of the airbag are attached with instruction labels, and the listed precautions should be strictly followed during operation. 7) After pulling out the airbag wiring plug, use a small copper wire to short the airbag connector. 8) Do not measure the resistance of the detonator tube of the airbag inflation element, so as not to cause the airbag system to explode by mistake. The method of decomposing the inspection parts should be adopted first, and then searching step by step. 9) The airbag system is a very sensitive device. A little carelessness during inspection may detonate the airbag and cause unnecessary losses. 10)The wire harness and connector of the airbag system are generally covered with a special color sleeve, which is different from other system wire harnesses. Do not damage these bushings during inspection. As a professional auto spare parts supplier, we provide car ignition components, car ignition coil, etc. For impact sensor price or more information, please feel free to contact us!
