2.3.1.4. Head of the block of cylinders

The head of the block of cylinders is made of aluminum and has combustion chambers of a maple form. The spark plug is located in the center of the combustion chamber. Inlet and final valves are located at an acute angle, equal 22,5 ° that provides compactness of a head of the block of cylinders. Inlet channels of small diameter are located vertically. The size of a vystupaniye of the directing valve plug to the inlet canal was reduced due to reduction of diameter of a rod of the valve and outer diameter of the directing valve plug. Bolts with the inhaling moment in a zone of plasticity are used for fastening of a head of the block of cylinders for ensuring good axial tension.
