    Abstract: A catalytically active surface is provided on the clean, combustion-exposed parts of an internal combustion engine that is green, has low operating hours, or is of modern, low emission design. A substrate or thermal barrier coat of high surface area and preferably capable of maintaining a surface temperature of at least 450null C. is deposited in the combustion chamber. Zirconia, silica, or lube oil ash are suitable. A catalytically active moiety such as platinum or iron is dispersed in, on, or with the combustion facing surface of the substrate. Nanophase iron from ferrocene or nanophase platinum are suitable. Catalytic action is maintained by continuously providing a low level of catalytic precursor to the engine in the combustion charge.

    Abstract: A coating and coating process to improve the efficiency of hydrocarbon fueled engines, wherein the coating includes a high percentage of nickel to create a reaction which improves the combustion efficiency of the hydrocarbon fuel. The coating may also include chromium, iron, and other constituents and is applied to combustion surfaces with a sufficient bonding strength to allow the coating to function in the combustion chamber, while providing a surface having sufficient surface roughness to promote the chemical reaction underlying the combustion efficiency improvement. The nickel causes a catalytic cracking reaction to ease the combustibility of hydrocarbon molecules in the fuel.

    Abstract: Catalyst structure, engine, and fuel injection system are disclosed, in which a catalyst structure is positioned between a fuel injector and a combustion chamber in which most or all combustion occurs. The catalyst structure typically promotes some combustion of the fuel, reforming of fuel to generate hydrogen and other reduced species of fuel molecules, or both. The catalyst structure may instead or additionally promote evaporation of fuel droplets. Benefits include reduced emissions of pollutants.

    Abstract: A catalyzer for a Diesel engine , where the catalyzer is located inside the combustion chamber, the pre-combustion chamber, the injector or the pre-heater. In one embodiment, the interior of the pre-combustion or combustion chamber is coated with a ceramic layer and submerged in an aluminum hydroxide and zirconium suspension. A coating of catalytic metals, such as rhodium, platinum, palladium, copper, silver aluminum, manganese and zinc, is then applied to the ceramic base inside the chamber. In another embodiment, the coating is applied by replacing the ceramic base by a bath of catalytic metals.
