Carburetor engines without converter
The ignition system of these engines consists of an ignition coil and a distributor with an integral switch, which is triggered by a magnetic sensor and causes high-voltage pulses to appear on the coil. The system is provided with a vacuum ignition timing controller, in the circuit of which a thermal vacuum valve is built in, which ensures that the optimum ignition timing is maintained when the engine is warmed up.
Carburetor engines with catalytic converter
The ignition system is integrated with the fuel system. Both systems are controlled by the ECC processor unit. An ignition coil and a crankshaft rotation sensor are built into the distributor. Based on the signals from this and other sensors, the ECC unit calculates the optimal lead angle and starts a powerful transistor module that interrupts the current in the secondary winding of the coil. The system is provided with a vacuum ignition timing controller, in the circuit of which two thermal vacuum valves are built.
