Abstract:
An adiabatic engine having an adiabatic member surrounding combustion chambers of the adiabatic engine, comprising:a cylinder having an inner side surface; a cylinder head having a lower surface; a suction valve and an exhaust valve respectively having a lower surface; and a piston having an outer side surface; on each of which the adiabatic member is mounted, wherein the adiabatic member provided at the upper part of the inner side surface of the cylinder is a predetermined space apart from the adiabatic member provided at the outer side surface of the piston, the adiabatic member provided at the inner surface of the cylinder and the adiabatic member provided at the outer side surface of the piston not coming into contact with each other, and the piston having a piston sealing ring fitted around a lower part on which the adiabatic member is not mounted, the piston sealing ring and the lower part of the inner side surface of the cylinder, on which the adiabatic member is not mounted, being in contact with each other.
