The summarized results as follow. Electronic Control System varied Spark plug Gap, and rpm, and catalyst apparatus, CO ,HC exhausted less and made the optimum control of the air-fuel ratio.
In case of the Spark Plug Gap 1.0mm, Spark Timing 15 degree and rpm 3000. Exhaust gas such as CO, HC reduced and Electronic control Engine of feed back control was effective in the spark timing control and reduced the amount of CO, HC but carburetor didn't work on the same way.
