Abstract
PURPOSE: To obtain an ignition timing characteristic where firing angle is delayed with a constant slope, by making charging/discharging eith a constant current at the standard crank angle position.
CONSTITUTION: A charging begins wigh a constant current I2 when the standard crank angle pulse A is generated at T1, and when the voltage reaches a constant voltage V2, discharging begins. An engine is fired at the point where said charging voltage reaches a constant voltage V2. Since delayed angle α is in fact equivalent a certain constant duration of time, higher the revolution, the more the firing angle will be delayed. If the number of revolution rises higher, the charge/discharge voltage will not completely be discharged. At this time, delayed firing angle becomes a constant fixed angle which is decided by the ratio of current I1 to current I2. Accordingly, a characteristic where the angle is delayed with a constant slope and a constant fixed delayed angle can be obtained with the above mechanism.
