Improving an IC Engine’s thermal efficiency by heat preservation by providing: heat insulation layers to the cylinder, piston crown, combustion chamber and cylinder-head including internal gaps/cavities with or without vacuum; reduced carbonisation of fuel and oil; reduced the thermal shock by exhaust gas recirculation - EGR with control/intake valves, heating and storage tank; improved thermal shock resistance of insulation with flexible/porous thread/fibre and cloth materials bound together by binding with paste, stitching, weaving, braiding or pressed/clamped together; improved distortion resistance using sapphire or tungsten steel; an elongated piston cap or cone; segmented or annular sheet cylinder/liner construction; direct or indirect cooling of fuel injectors with fuel recirculation or spark plugs with high pressure gas jets in pits or slits.
1-98. (canceled)
A type of heat resistant material piston engine comprising heat-resistant material, wherein the heat-resistant material partially or wholly comprises a plurality of smaller members/pieces which are pressed together by an external force, wherein the heat-resistant material form part or all of a piston insulation layer, and/or part or all of a cylinder insulation layer, and/or part or all of a cylinder head insulation layer, and/or part or all of a combustion chamber insulation layer.
A type of reciprocal piston engine comprising a heat-resistant thermal insulation material layer for a piston and/or cylinder and/or cylinder head and/or combustion chamber, wherein the thermal insulation material layer contains one or more cracks.
