The cylinder block is cast from aluminum alloy and is integral with the upper part of the crankcase.
The block has a water jacket cavity that is open upward, into which cast iron sleeves are inserted with support in the bottom of this cavity

On the engine mod. ZMZ-4062 type A14DVR spark plugs are installed on engines mod. ZMZ-402 and ZMZ-4021 - type A14VR

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

The piston of the 1st cylinder is set to the top dead center (TDC) position of the compression stroke so that when carrying out work related to removing the timing chains, the valve timing is not disturbed

The timing mechanism is driven by a toothed belt 6 from the crankshaft pulley 1
The toothed belt is tensioned by the eccentric bearing of the tension roller 5
