In the electric control mechanism a change-over switch 1 changes over when change-over time reaches t1. Further, for the change-over time t1, the time difference between the change-over signal and the start signal of the change-over switch 1 is measured and read in. This time t1 is compared with a set value that temperature and pressure are compensated and is judged into four stages. Next, the change-over time of the change-over switch 1 itself is read in and is compared with a set value t2 similar to the said one and is judged into four stages. Furthermore, total change-over time t is read in and is judged into four stages similarly, and the monitoring of one tap changing time limit is finished.

Abstract: PURPOSE:To increase the rate of fuel consumption and reduce emission of exhaust gas by making the angle delay greater with higher temp. of the suction gas, and by making the angle delay at the same temp. smaller with leaner condition in the air-to-fuel ratio. CONSTITUTION:A controller 18 determines the fundamental injection amount and fundamental ignition timing through map scanning etc. by the use of the number of engine revolutions N, the amount of suction air Q, and the suction gas temp. t, and upon determining the amount of fuel injection, drives a fuel injection nozzle 8. Calculation of corrective retard amount is made by feeding signals of an air-to-fuel ratio 19, wherein the retard amount for ignition timing is made greater as the suction temp. t becomes higher from a specified temp., and at the same time, the retard amount at the same suction temp. is made smaller as the air-to-fuel ratio becomes leaner in response to the air-to-fuel ratio. Thus increase of the rate of fuel consumption and reduction of exhaust gas emission can be obtained by preventing output drop and knocking generation even in case the air-to-fuel ratio is controlled in accordance with the operating condition.
