摘要：
A multi spark discharge ignition mode with a single capacitor for a two stroke air-assisted direct injection spark ignition engine fueled with diesel was proposed, and a direct current multi spark capacitor discharge ignition system was developed, in which the multi spark ignition mode was verified and ignition energies were tested. On these basis, the engine tests of cold start and low load at 3000r/min under 6℃ ambient temperature were conducted. The test results show that, applying 5 times capacitor discharge ignition is able to make a successful engine cold start, and under the low load condition, increasing the ignition times promotes the combustion in cylinder; 4 times ignition is obviously more beneficial to improve the power performance, fuel economy and emissions performance than 2 times ignition with the ignition advance angle between 10° crank angle before top dead center and 20° rank angle before top dead center; the improvement effects gradually become small with the ignition timing angle advanced to 30° crank angle before top dead center. © 2017, Editorial Department of Journal of Aerospace Power.
