随着科学技术的发展,节约能源和控制污染,将是人们研究的一个重要课题。然而对汽油机来说,提高点火性能则是其中一个方面;采用下述两个措施,可以提高点火性能。1．提高点火线圈的效率目前国内汽车发动机上用的点火线圈,都是采用开磁路方式,这种变换效率一般为60%,而采用闭磁路方式其变换效率可提高到75%。从而减少了变换损失。采用闭磁路方式,对获得较大的磁通有利,对磁
With the development of science and technology, energy conservation and pollution control will be an important issue for people to study. However, for gasoline engines, improving ignition performance is one of the aspects. The following two measures can improve ignition performance. 1. Improve the efficiency of the ignition coil At present, the ignition coil on the domestic car engine, are used to open the way of the magnetic circuit, this conversion efficiency is generally 60%, while the use of closed magnetic circuit its conversion efficiency can be increased to 75%. Thus reducing the conversion loss. Closed magnetic circuit approach, to obtain a larger magnetic flux, magnetic
