Carburetor engines without a neutralizer
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 has a vacuum ignition advance regulator, in the circuit of which a thermal vacuum valve is built in, ensuring that the optimal ignition timing is maintained during engine warm-up.
Carburetor engines with a neutralizer
The ignition system is integrated with the fuel system. Both systems are controlled by the ECC processor unit. The distributor has an ignition coil and a crankshaft rotation sensor built into it. Based on signals from this and other sensors, the ECC unit calculates the optimal advance angle and starts a powerful transistor module that interrupts the current in the secondary winding of the coil. The system has a vacuum ignition advance regulator, in the circuit of which two thermal vacuum valves are built in.
