摘要： PROBLEM TO BE SOLVED: To provide an ignition device for an internal combustion engine which can perform an ignition operation at an optimal ignition timing.
SOLUTION: The ignition device for an internal combustion engine includes a crank angle sensor 2 and a control means 1. The crank angle sensor 2 outputs at least three crank angle signals during one rotation of a crankshaft. The control means 1 decides deceleration of the crankshaft from those crank angle signals and also decides the time of outputting an ignition signal to an ignition coil from the deceleration. The ignition device for an internal combustion engine can perform an ignition operation at an optimal timing even when the rotating fluctuation in one combustion cycle is relatively large.

摘要： PROBLEM TO BE SOLVED: To control exhaust valve opening/closing appropriately so as to fully obtain an engine output or prevent hunting of the exhaust valve. SOLUTION: In this control method, exhaust timing is advanced or delayed by opening and closing an exhaust valve according to an engine speed. When the speed is high, a speed na (na1, na2, etc.), is controlled at the beginning of the valve opening so that the exhaust valve is full open when a predetermined set speed n0 is satisfied. When the speed decreases while the exhaust valve is fully open but a throttle is not, the exhaust valve is closed when the speed satisfies nb, which is higher than n0 at which the exhaust valve opens when the speed increases.
