2.1.1.4. Head of the block of cylinders

Fig. 2.6. Cross-section and top view of a head of the block of cylinders: 1 – fuel nozzle; 2 – roundabout channel; 3 – conical displacer


The combustion chamber of a maple form is used to provide high detonation resistance and fuel profitability of the engine. The vertical inlet channel is used for increase in efficiency of process of an admission. Installation of fuel nozzles in a head of the block of cylinders allows to provide fuel supply as it is possible closer to the combustion chamber. It interferes with sedimentation of fuel on walls of the inlet channel that reduces emissions of CH with the fulfilled gases. The arrangement of channels of a shirt of cooling in a head of the block of cylinders is optimized for increase in efficiency of cooling. Besides, below outlets there was an additional channel of cooling that reduced quantity of details and allowed to reach decrease in the weight (fig. 2.6).
