82 5 ELECTRICAL PARTS B Ignition coil The ignition coil employed in Model CB 125 and CB 160 provided with 360 alternative combustion is of simultaneous ignition system which is employed in vehicles manufactured by our company and while ignition and combustion takes place in one side the other is not utilized Refer to Fig 5 5 1 Construction of the ignition coil As shown in the figure the ignition coil is manufac tured in such a way that the secondary coil with a thin enamel wire 0 08 mm wound around the iron core coil from 10 000 with a to thicker 20 000 wire times 0 6 at mm the primary wound several hundred times are put in a water proof case after insulation treatment is performed pitch or other is employed for filling the space Refer to Fig 5 6 2 Performance of ignition coil The principle of the ignition coil is the same as that of the induction coil Connection is generally made as shown in the left figure when the cam axis and the crankshaft axis are rotated at a high voltage Fig 5 6 Dual side view of ignition coil Generali generated at the secondary coil by the following process Refer to Fig 5 7 a SECONDARY CURRENT When the breaker points are closed primary current flows in the direction of the arrow mark IGNITION COIL and magnetic flux is the iron core PRIMARY CURRENT b INSULATING MATERIAL breaker points are opened the cam is rapidly reduced BREAKER POINTS BREAKER POINT CAM CAPACITOR Fig 5 7 Battery operation coil Generali the the magnetic flux generated by the primary current SPARK PLUG BATTERY PRIMARY SID When c High voltage is generated at the secondary by the change of magnetic flux and difference between the number of rotation Self and mutual induction operation d The high voltage fills the distributed static capa city of the secondary coil first and upon the voltage increase the high tension cord and the distributed static capacity in the plug are charged simultaneously and voltage gradually increases e When voltage is sufficient the spark is discharged Upon the start of discharge discharge voltage drops rapidly with the load of the distributed static capacity released capacitive sparks discharge is continued due to energy stored in the windings by the decrease of magnetic flux inductive sparks Fig 5 8
