Title: Ignitiion timing control device of universal engine
Inventor: MATSUI MASAYOSHI
IPC: F02P5/15
Filed: 1999-09-28
Abstract: PROBLEM TO BE SOLVED: To suppress the hunting in various rotating speeds in the operation of a universal engine. SOLUTION: The universal engine 2 comprises an ECU 38 as the ignition timing control device. The ECU 38 performs an ignition timing control processing and calculates a final ignition timing HSig (S140) by correcting the basic ignition timing Sig calculated on the basis of the detected present rotating speed (S130) with the sum of partial correction quantities Hi calculated on the basis of the displacement Di of the engine rotating speed (S120). The ECU 38 controls the ignition timing of an ignition drive unit 34 to drive an ignition plug 32 so that the spark discharge is performed at the final ignition timing HSig. According to this, since the final ignition timing HSig is calculated so as to stabilize the engine rotating speed in not a specified rotating speed but various rotating speeds, the hunting can be suppressed in various rotating speeds.
