| Abstract: | A non-linear model is set up for engine transient operating conditions.Both sliding mode controller and PID controller are designed to realize adaptive regulation of throttle opening and ignition timing respectively.The results of simulation on engine idling show that the amplitude of engine speed fluctuation is less than 6 r/min,indicating that the non-linear model built is appropriate for the control over the transient operating conditions of engine. |

| Keywords: | engine transient operating conditions control non-linear model throttle opening igni-tion timing |
