PROBLEM TO BE SOLVED: To easily adjust an ignition timing by mechanically adjusting the deviation of a detection timing by adjusting the positions of detection sensors 5 when the deviation of the detection timing occurs due to an error in mounting of the detection sensors 5 and a rotor 2. SOLUTION: In this spark ignition engine, a rotor 2 is fitted to a rotating shaft 1, ignition indicating parts 34 are circumferentially arranged on the rotor 2, and the detection sensors 5 face the passing positions of the ignition indication parts 34. The detection sensors 5 are associated with an ignition circuit through an ignition controller, and based on the detection of the ignition indicating parts 3 and 4 by the detection sensors 5, the ignition controller transmits ignition instruction signals to the ignition circuit. The positions of the detection sensors 5 are movably adjusted along the circumferential direction of the rotor 2. COPYRIGHT: (C)2004,JPO
