专利汇可以提供Ignition timing control method专利检索,专利查询,专利分析的服务。并且PURPOSE: To prevent a sudden and discontinuous change of ignition timing and relieve accelerating shock when operating conditions change in an electronical ignition timing control device by controlling the variation volume of ignition timing within a specified range.
CONSTITUTION: The value of ignition timing M is retrieved from the primary and secondary properties responding to throttle opening from P
1 , P
2 and P
4 in a flow chart. A specified time passage is retrieved from P
5 after the throttle is fully opened. The ignition timing value PD from the previous operation and the ignition timing M are compared by P
7 , P
9 , P
10 and P
12 . Responding to the comparison result, the ignition timing values PD and M are controlled by P
8 , P
11 and P
13 below a specified value. P
7 and P
12 are applied for the angle of advance while P
10 is applied for the angle of delay. With this construction, the difference between the ignition timing values PD and M can be controlled below a specified value in all cases, which prevents ignition timing from suddenly and discontinuously changing.
