Distributor with induction transmitter
In the contactless transistorized coil ignition system with inductive transmitter (TSZ-i), the
mechanical control switch is replaced by a pulse transmitter.
The inductive transmitter in the distributor casing consists of a moving part, the pulse
transmitter wheel, and a fixed part, the disc with a permanent magnet, induction coil and
core. The pulse transmitter wheel is mounted on the distributor shaft and as it rotates,
produces an AC voltage in the induction coil whose frequency is proportionate to the
speed and the number of cylinders of the engine. This AC voltage is passed as a control
signal from the distributor via a two-wire transmitter line to the control unit.

1 Pole disc
2 Distributor shaft (do not lubricate felt provided)
3 Pulse transmitter wheel
4 Coil carrier
The distributor rotor and distributor cap should be renewed after every 6000 hours
operation.
Control unit
In the control unit, the signal from the inductive transmitter is converted and transformed
by means of the ignition coil to a high voltage. The high voltage pulses are distributed
same as in a non-transistorized coil ignition system via the distributor rotor and cap to the
engine cylinders.
