The microprocessor ignition system is designed to ignite the working mixture in the engine cylinders by setting the optimal ignition timing for a given engine operation mode

The ZMZ-406 engine is equipped with a microprocessor ignition system, which consists of a control unit for fuel injection and ignition systems, two ignition coils of types 30.3705 or 301.3705, candles, high-voltage and low-voltage wires

Ignition coils are designed to generate high voltage electric current to ignite the working mixture in the engine cylinders

The cylinder block is cast in gray cast iron.

There are coolant channels between the cylinders

Microprocessor engine control system ZMZ-406:

• - controls the power supply of the fuel pump;

When the ignition is switched on, the indicator lamp lights up (for 0.5 s) and goes out if the self-diagnosis system has not detected a malfunction

Synchronization sensor - inductive type (2612.1.113 Bosch or 406.3847113) is installed on the front end of the engine at the bottom, on the right side and is designed to synchronize the operation of the control unit with the engine workflow

The camshaft position sensor (0232103006 or 406.3847050-10) is installed in the end of the cylinder head on the left side of the flywheel

High voltage wires are made of PV PPV wire with a diameter of 8 mm

A helix of nichrome wire is wound on a core with a ferrite filler

The VAZ-21126 engine is based on the VAZ-2112 engine

Increasing engine displacement mod. 21126 up to 1.6 l compared to displacement mod. 2112 is achieved by increasing the piston stroke while keeping the cylinder diameter unchanged.
