Abstract: The method for operating a real machine, thermodynamical diesel engine according to a diesel- or wire-circuit process with partial adiabatic components, which comprises an emulsifier composition for diesel emulsions, vegetable oil emulsions and fuel emulsions that are produced in a stationary or movable mixing- and emulsifying system, a fuel filter in the engine made of paper or felt, a one-piece uncooled light-weight metal piston or assembled two-part piston with internally cooled piston crown made of steel and an emulsifier-solution, is claimed. The method for operating a real machine, thermodynamical diesel engine according to a diesel- or wire-circuit process with partial adiabatic components, which comprises an emulsifier composition for diesel emulsions, vegetable oil emulsions and fuel emulsions that are produced in a stationary or movable mixing- and emulsifying system, a fuel filter in the engine made of paper or felt, a one-piece uncooled light-weight metal piston or assembled two-part piston with internally cooled piston crown made of steel and an emulsifier-solution, is claimed. The method is carried out without or with up to 30% of performance improvement in a semi-vapor-diesel process. The emulsifier-solution consists of composition following four main components, emulsion premixture and three supporting emulsions, where the emulsion premixture consists of 11% of powdered hydrophobic agent bearing sodium oleate CAS No 67 701-11-5, fatty acid, 14-18 carbon and 16-18 carbon unsaturated with sodium salts, 14% of water as solvent without lubricating effect, 7% of glycerin 99.5 as lubricant, 6% of propylene glycol as antifreeze agent related to 38% of emulsion premixture. For ensuring a stable bandwidth of emulsifying effect, the three supporting emulsions contain 6% of oleic acid ethoxylated with coconut compounds with diethanol amine, 8% of fatty acid amide polyglycol ether (hydrophilic) and 48% of polyoxyethylene (20) sorbitan monooleate related to the 100% of the emulsifier solution. The amount of the hydrophilic portion sets itself to a desired stable standing time of an emulsion for 3-6 months without water separation at the ground. The need of emulsifier solution is halved when 5-10 vol.% of emulsification-friendly substitute fuel made of bio-ethanol and gasoline for gasoline engines is added during emulsification. Independent claims are included for: (1) a long-term stable thixotropic water-in-oil-fuel emulsion; (2) a process for mixing of water, replacement-fuel bio-ethanol with gasoline and emulsifier solution in an order in a mixing plant; (3) a combined mixing- and emulsifying system stationary or movable before a diesel engine or a conventional tank column with a plug valve for emulsifying a mixture; (4) a particle-free vapor-diesel engine; (5) a fuel-filter; (6) a hot combustion chamber shell, in the form of a heat shield in a thermoelastic sandwich construction, as a heating surface for further overheating of the steam; (7) a method for reducing a heat flow by matching the thickness of the insulating mat; (8) anchor shelves; (9) an expansion joint; and (10) an insulating mat.
