摘要

The process for the guidance of eco-diesel engine, comprises reducing the engine working temperatures with greater compression ratio of epsilon that is equal to 19V21 and corresponding larger internal gas expansion ratio (delta ) on the basis of thermodynamic working processes during the engine compression, where the pressurized water evaporation-direct cooling of 10-20 kg steam/kg fuel (according to the height or compression temperature) triggered with 80-50[deg] of crank angle above over-temperature in the upper cylinder area takes place by starting the main compression phases. The process for the guidance of eco-diesel engine, comprises reducing the engine working temperatures with greater compression ratio of epsilon that is equal to 19V21 and corresponding larger internal gas expansion ratio (delta ) on the basis of thermodynamic working processes during the engine compression, where the pressurized water evaporation-direct cooling of 10-20 kg steam/kg fuel (according to the height or compression temperature) triggered with 80-50[deg] of crank angle above over-temperature in the upper cylinder area takes place by starting the main compression phases in the steam superheating-temperature range of the self-condensing compression air far before the fuel ignition (10-6[deg] Kw above over-temperature) prior to the homogenization of the produced hot stream with the self-condensing compression air for ignition minimal distortion of smallest possible compression final temperatures, so that it previously theorizes with the low compression final temperatures of 853[deg] KV873[deg] K multiplied with the same and the complete pressure ratio of 2.3 or 2.25 adjusts itself the combustion temperature level to the maximum nitrogen oxide-gas free combustion temperature level of 1873-1963[deg] K corresponding to 1600[deg] C to maximum 1690[deg] C (complete load) by the resulting partial vapor pressures with consistent engine power as before. The process improvement enables by reducing heat requirement with elevated pressure gradient. Independent claims are included for: (1) a method for reducing critical air ratios; and (2) an arrangement of two pressurized water injection nozzles oppositely right-angled to a cylinder axis per engine cylinder.
