    • An engine control system includes a disturbance module, a misfire threshold determination module, a disturbance ratio module, and a spark control module. The disturbance module determines a disturbance value for a past combustion stroke of a cylinder based on rotation of a crankshaft. The misfire threshold determination module determines a jerk value indicative of a misfire within the cylinder. The disturbance ratio module determines a disturbance ratio for the past combustion stroke based on the disturbance value and the jerk value. The spark control module determines a spark timing for a future combustion stroke of the cylinder, determines a spark timing correction for the future combustion stroke based on the disturbance ratio, determines a corrected spark timing based on the spark timing and the spark timing correction, and generates spark during the future combustion stroke based on the corrected spark timing.
    • 发动机控制系统包括干扰模块,失火阈值确定模块,扰动比模块和火花控制模块。 干扰模块基于曲轴的旋转来确定气缸的过去燃烧冲程的干扰值。 失火阈值确定模块确定指示气缸内的失火的冲击值。 干扰比模块根据扰动值和冲击值确定过去燃烧行程的扰动比。 火花控制模块确定气缸的未来燃烧冲程的火花正时,基于干扰比确定未来燃烧冲程的火花正时校正,基于火花正时和火花定时校正确定校正的火花正时,以及 基于校正的火花正时,在未来的燃烧冲程期间产生火花。
