Pulse igniter usually consists of three parts: transformer, module and spark plug.
The function of transformer is to convert low voltage into high voltage. The transformer consists of two coils, one is a high-voltage coil (spark coil) and the other is a low-voltage coil (secondary coil). The secondary coil is connected to the power supply through the automobile power cord, and the high-voltage coil outputs high-voltage electricity through the module.
The module (or controller) is the core part of the pulse igniter, which controls the transformer to output high-voltage electricity through the pulse control circuit and adjusts the pulse width and frequency. The module controls the spark plug to generate sparks by detecting the working state of the internal combustion engine.
The spark plug is the last part of the pulse igniter, which is located in the combustion chamber of the engine and receives high voltage electricity and generates sparks. The spark plug consists of a conductive rod and a central electrode. When high-voltage electricity is transmitted to the central electrode through the conductive rod, sparks will be generated to ignite the mixture of gasoline and air.
Generally speaking, the working principle of pulse igniter is to convert low voltage into high voltage, and then control the spark plug to generate sparks by adjusting the width and frequency of high voltage through the module, thus igniting the mixture of gasoline and air. Because this ignition method can be more accurate and reliable, pulse igniter has become the mainstream of automobile engine ignition system.
Yes, pulse igniters have important applications in automobile engines. In addition to ignition, it can also achieve other functions, such as:
Improve fuel economy: pulse igniter can accurately control ignition timing, thus improving fuel economy.
Improve emission performance: pulse igniter can improve combustion efficiency and reduce emissions.
Increase engine power: Pulse igniter can accurately control ignition timing, thus increasing engine power.
However, the pulse igniter also has some disadvantages, such as:
Electronic components are prone to failure and the maintenance cost is high.
The price is high and the installation is difficult.
When the pulse igniter fails, it may cause the engine to fail to work normally and need immediate maintenance.
Generally speaking, although pulse igniter has some shortcomings, its application in automobile engines has become an indispensable part, which has made important contributions to improving engine performance, fuel economy and emission performance.
