Description:
An insulative piston or piston cap creates a highly thermally resistive path in the axial direction of the piston or piston cap toward a crank case of an engine. An insulative cylinder is configured to be positioned around the insulative piston and adjacent an insulative cylinder head, and to provide thermal resistance in the cylinder's axial direction. The insulated cylinder head is configured to resist heat flow in the axial direction away from the crank case. High temperature insulation surrounding these structures is configured to resist heat flow out of a combustion chamber of the engine. These insulative components, together, form the fully insulated combustion chamber.
