36. stem Some actually measure the AC frequency created by the car s alternator Because the number of pulses per crank rotation is dependent on the ignition system and engine type a universal RPM measurement method must be adaptable to the different environments encountered The typical ignition system consists of an ignition coil a coil driver that switches current to the coil on and off and a distributor When current is switched on to the coil the coil stores energy in its magnetic field When the current is switched off that energy gets discharged at a very high voltage pulse on the coil s secondary winding creating a spark A capacitive discharge ignition system CDI uses a capacitor to store the spark energy The capacitor is charged to about 400V and then rapidly discharged over the ignition coil s primary winding The coil thus only acts as transformer and does not store energy and can therefore be smaller The advantage of a CDI system is a very high and fast rising spark voltage less susceptible to spark fouling The weakness of the CDI system is the very short duration spark which might not be long enough to ignite the mixture Multispark ignition systems try to overcome the inherent weakness by creating multiple spark pulses over some degrees of crank rotation to increase the likelihood of igniting the mixture The distributor switches the spark voltage to the appropriate spark plug 7 1 1 Four Stroke Engines On a typical 4 str
