With the development of gasoline engines in automobiles towards high speed, high compression ratio, high power, low fuel consumption, and low emissions, traditional ignition devices are no longer suitable for use. The core components of ignition devices are ignition coils and switch devices. By increasing the energy of the ignition coils, the spark plug can generate sufficient energy to produce sparks, This is the basic condition for the ignition device to adapt to the operation of modern engines. The ignition coil is divided into two types according to the magnetic circuit: open magnetic and closed magnetic. The traditional ignition coil is used with an open magnetic type, and its iron core is stacked with about 0.3 millimeters of silicon steel, with secondary and primary coils wound around the iron core. The closed magnetic type uses an iron core similar to III to wrap around the primary coil, and then wraps around the secondary coil outside. The magnetic field line is composed of an iron core to form a closed magnetic circuit. The advantage of the closed magnetic ignition coil is that it has less magnetic leakage, Due to its small energy loss and volume, electronic ignition systems generally use closed field ignition coils)
Spark means "spark" in English. This word is perfect to describe the small car launched by SAIC GM Wuling last year. Whenever it appears on the streets and alleys, it always gives the impression of a cluster of jumping sparks that jump into people's eyes. The workmanship of the 2007 Spark is still excellent, and the thick paint surface is very satisfactory. Even the red Spark that we test drove, which has an ordinary paint surface, The shiny paint also reflects the reflection of the roadside buildings. The excellent spray painting process provides a rich selection of body colors for Spark Lecci, and every Spark Lecci owner can easily choose their favorite color from the six color chart
