Abstract: A self-lubricating piston for an internal combustion engine comprises a composite coating adhered to a grooved piston surface and containing therein a first reinforcing phase of high tensile strength, high modulus of elasticity, reinforcing fibers of graphitic structure and a second reinforcing phase of powdered solid lubricant. The fibers are spooled around the piston and continuous for at least two turns. The fibers are preferably contacted along their lengths with longitudinally discontinuous bands of high thermal conductivity soft material forming multiple radial heat transfer paths throughout the composite layer.

Abstract: Exhaust gas from an internal combustion engine is analyzed to define volumetric percentages of selected component gases therein by an apparatus affording direct reading of such percentages and cooperating at high speed. The apparatus comprises float and tube flowmeters interspersed in a flow series with selective sorbents for the gas components to be measured. The tubes of the flowmeters are arranged in parallel alignment with each other and have scales therebetween to display said percentages directly.

Abstract: An operative internal combustion engine is transparent for demonstration of internal combustion engine principles. A transparent cylinder houses a noncontacting piston, the combustion chamber being sealed by means such as protruding annular teflon rings seated in an annular groove of the piston or a flexible flap formed integrally with the piston which is pressed firmly to the internal surface of the cylinder wall by pressure developed within the combustion chamber during operation of the engine. Other portions of the engine are transparent to enable their contained parts to be observed during operation. The engine also has an enlarged flywheel to permit operation of the engine at low, observable speeds. The invention burns low carbon fuels such as alcohol to keep the cylinder walls clean and operate without polluting the air.
