【Abstract】 Ignition control of spark\|ignition engines must be able to satisfy a great diversity of work of engines. The centrifugal advance of spark advance angle is an important part of control in engine. There are some defects of response and instable set of data in the control system made up of machanical device. Using electronic imitation as measure and several kinds of representative ignition distributors’s centrifugal advance characteristic as criterion, this paper realizes electronicization and controllization of centrifugal advance, thus offering convenience for real time ignition control of engines. The test of testbed shows that the advance characteristic is completely up to the standard.\;更多还原
