The major technologies used include increasing compression ratio, changing sparkadvanceAngle and using intake pulse turbo-charging.
主要采取了提高压缩比、改变点火提前角及采用进气脉冲增压技术。

Finally the calibration on a WF4C27F-E gasoline engine is performed, and the MAP graphs of the volumetric efficiency and the sparkadvanceAngle are obtained.
最后针对WF4C 27 F - E汽油机进行了标定试验，获取了充量系数和点火提前角MAP图。

The results showed that the adjustment by sparkadvanceangle on the idling speed was notable, thus, CMAC controller is an effective approach for controlling engine idling speed.
