International vendor verification

Engine ignition (engine start-up: analysis of vehicle ignition technology) Engine ignition is International vendor verificationone of the key steps of vehicle start-up. It is the process of igniting the mixed gas, causing combustion and making the engine run. In the engine ignition, the electrical signal ignites the gasoline mixture through the ignition plug, which further triggers the engine to work.In the automobile manufacturing process, the design and production of the ignition system are constantly improved to better adapt to different engine structures and uses, and improve performance and reliability. I. Ignition principle Ignition refers to the fact that the spark generated by the spark plug is generated in the gasoline mixture under the condition of the timing of the engine, igniting the mixture, causing the mixture to explode, thus producing combustion in the cylinder, generating energy, driving the piston to work, and thus driving the engine. Commonly speaking, it is to ignite gasoline, explode, and burn with the air in the cylinder to drive the engine through the working journey. II. Ignition method 1 Electromagnetic ignition Electromagnetic ignition is the traditional car ignition method. In this way, the whole system includes parts such as ignited mixed gas, exhaust, wires, ignition plugs, electrical signal generators and boilers. Sometimes electromagneticThe principle description of ignition can also be called hit-fire ignition, that is, the ignition method is carried out through the spark rotor. When the electrical signal enters the ignition coil, the high-voltage current representing the high-voltage signal begins to be generated, and the spark is inserted into the spark plug to ignite the gas mixture. From this, start the engine to start the car. 2 Electronic ignition Due to some shortcomings in electromagnetic ignition technology, such as easy loss of ignition efficiency, electronic ignition has gradually become an important automobile ignition technology. Once a high pressure is generated, it will immediately generate sparks to ignite the mixed gas. After the ignition is completed, the electronic ignition can also automatically optimize the ignition time, so as to improve the performance of the car and obtain better power. In the process of achieving this, the engine control unit (ECU) can read the data from the engine sensor, determine the next ignition time, and then trigger the entire ignition system to complete the ignition work.In this way, the whole system must be a high-rotating electronic computer for accurate calculation and control. III. Ignition system Ignition system is a key subsystem on cars. The whole ignition system is composed of multiple components such as power supply (battery, generator), switch, ignition cable, ignition plug, ignition cable plug, ignition coil, control module, sensor, ECU, ignition computer and sensor. The ignition coil is one of the important components, which is mainly responsible for generating high-voltage pulses. In addition, the ignition plug is responsible for igniting the mixed gas, which is one of the key parts to start the engine. In the automobile manufacturing process, different manufacturers and different models of automobile ignition systems are specialized and evolved. For example, some advanced ignition systems can achieve adaptive control, dynamic computing and other features to adapt to complex road environments and driver behavior.IV. Frequently asked questions and troubleshooting of ignition. During the operation of the car engine, there may be some problems with the ignition system. Generally speaking, these problems include the following aspects: 1 The engine is difficult to start, and the engine can only be started after many start attempts. Cause: It may be caused by the ignition line is broken or short-circuited, the power supply problem of the ignition coil or the quality problem of the ignition coil itself; it may also be that the ignition plug is burned or contaminated. Troubleshooting: You can check whether the electrical promotion circuit is normal and detect the ignition coil and ignition coil power supply. In addition, the problem can be fixed by replacing the ignition plug. 2 The engine is not working stable. Reason: It may be caused by the wrong ignition time, insufficient ignition intensity, mixed gas fire and other problems. Troubleshooting: The problem can be solved by detecting the ignition time, locating the insufficient ignition intensity and readjusting the timer.3 Flying fire or cylinder losing fire. Reason: It may be caused by rust of the ignition plug, insufficient ignition strength, excessive output current of the ignition coil and other problems. Troubleshooting: The problem can be solved by replacing the ignition plug, readjusting the ignition time and another power interface. In summary, engine ignition is one of the key steps to start the vehicle, which is the process of igniting the mixed gas, causing combustion and making the engine run. In the automobile manufacturing process, the design and production of the ignition system are constantly improved to meet different engine structures and uses, and improve performance and reliability. For some problems in the ignition system, it can be troubleshooted and corrected by detecting the circuit, replacing the ignition plug and other methods.
