FIELD: mechanical engineering.
SUBSTANCE: invention belongs to the engine building, and more specifically to the piston engine combustion chamber (CC), subdivided into two or more parts, as well as CC, characterized by a special form, aimed at operational process improvement. The piston engine combustion chamber, created by the engine head surfaces, piston and cylinder bottom (at that the cylinder head contains an insertion piece out of thin-wall tube) and positioned diametrically through the ignition spark plug plain surface from the side of displacer along the cylinder centre and going out of the head in parallel to the cylinder axis; moreover are refrigerating fluid drainages through the tube. An insertion piece out of thin-wall tube is installed under the cylinder cover or at the coolant jacket cavity.
EFFECT: provision of temperature mode which allows overheat eliminating and prevents blowholes in the combustion chamber.
