有些电子点火系统已经减轻了分电器的点火提前的任务,然而福特的工程师们已更前进了一步,他们采用的系统已完全去掉了分电器。这个实验性的无分电器点火系统(简称DIS),采用了双头线圈输出相反极性的高压电供给成对地布置在整流电路中的火花塞。与常规的点火系统相比,DIS能显著减少电磁辐射及扩大点火提前角范围,并改进其紧凑性。它的每一
Some electronic ignition systems have lightened the distributor’s ignition advance, yet Ford engineers have taken one step further and the systems they use have completely eliminated the distributor. This experimental, distributorless ignition system (DIS) employs a high-voltage power supply of double-headed coil output of opposite polarity to supply spark plugs arranged in pairs in a rectifier circuit. Compared with the conventional ignition system, DIS can significantly reduce the electromagnetic radiation and expand the range of ignition advance angle, and improve its compactness. It’s each one
