Title: Ignition device for two-cycle engine
Inventor: HAYAZAKI YOSHIAKI
IPC: F02B75/02
Filed: 1990-08-16
Abstract: PURPOSE:To make combustion at the high-speed delay time positive so as to prevent uneven combustion by providing two spark plugs, and igniting one spark plug always, while igniting the other spark plug at least at the high-speed delay time. CONSTITUTION:A spark plug 56 is fitted approximately on the cylinder center axis so that its ignition part faces almost the center of a combustion chamber 44, whereas a spark plug 58 is fitted into a position displaced rather onto the exhaust port 52 side than the cylinder center axis, and both are ignited simultaneously by an ignition circuit 64. This ignition circuit 64 is provided with a CDI (condenser discharge type ignition device) and a CPU. That is, electric charge is charged into a condenser by a charging coil 62a, and the optimum timing for engine speed is computed by the CPU using the timing of a pulser coil 62b. At this timing, a primary current is supplied to an ignition coil 66 so as to simultaneously ignite both spark plugs 56, 58 series-connected to the secondary side coil of the ignition coil 66. The CPU also computes the timing so as to delay the ignition timing at high speed.
