Combustion chamber fire plate is located apart from connection with the unit by means of a groove formed at cylinder head lower plate, where the groove forms the outer line of combustion chamber fire plate. Note that there is a gap between combustion chamber fire plate and unit connection area. The groove goes round the larger part of fire plate outer line. The groove, at least partially, vertically protrudes behind cylinder liner of cylinder block and the groove is connected by fluid with fluid sleeve located around cylinder liner. The version of cylinder head and engine with cylinder head performance is described. ^ EFFECT: improvement of cylinder head inner walls stiffness. ^ 19 cl, 6 dwg |
