摘要： PURPOSE: To reduce the amount of generating smoke and NOx to approximately zero as the generation of unburnt HC is suppressed. CONSTITUTION: Fuel is injected in a combustion chamber 5 during a compression stroke or a suction stroke in a 60 deg. or less arc before an approximate compression top dead center and in this case, the more the position of a piston 4 is situated downward, the more the spread angle of injection fuel is reduced. Further, in this case, the average grain size of current injection fuel is increased to a value higher than a grain size when the temperature of fuel particle reaches the boiling point of a main fuel component determined by a current pressure at an approximate compression top dead center or after a compression top dead center. During a time in which it attains an approximate compression top dead center after injection, vaporization of fuel from fuel particle due to boiling is blocked, and after the approximate top dead center, fuel of fuel particle is boiled for evaporation after the approximate top dead center, and the fuel is ignited for combustion.

摘要： PURPOSE:To improve combustion in both high and low load ranges of a Diesel engine to reduce the fuel consumption rate and the amount of detrimental components in exhaust gas, by providing such an arrangement that the timing of initiation of fuel injection is made remarkably earlier when the load of the engine lowers, in comparison with the timing of initiation of fuel injection upon large load operation. CONSTITUTION:The engine load L is taken along the ordinate, and the crank angle theta at which the fuel injection is initiated and the opening rate R of the exhaust control valve are taken along the abscissa. Further, the broken lines E, G exhibit the opening rates R of intake and exhaust control valves, repsectively, and the chain line F exhibits the timing of initiation of fuel injection in a conventional Diesel engine. In this case, the timing of initiation of fuel injection is set to be effected at a point in the vicinity of 120 deg. before the TDC in each compression stroke upon low load operation. It is noted that this timing of initiation of fuel injection is actually possible during the period from a point in the vicinity of 90 deg. of the TDC in each expansion stroke to a point in the vicinity of 130 deg. after the BTD of each of exhaust, suction and compression stroke. Further, as the load increases, the timing of initiation of fuel injection is gradually retarded, and it is set at a point in the vicinity of 10 deg. of the TDC in the range of the load L0.

摘要： A method of reducing ignition delay tau , of fuels to negligible values and negligible differences is disclosed. Fuels conditioned to have such negligible values and differences are readily used in multiple fuel engines, such fuels self-ignite substantially instantaneously when injected into an oxidant, require substantially no heat transfer from the oxidant to effect the self-ignition, and the self-ignition is sufficient to sustain continued combustion.

摘要： The operating method requires a sensor (10) for detecting at least one operating parameter of the engine in the partial load range, for determining the start point of the fuel injection and the opening and/or closing points of the engine inlet and outlet valves (4,5), to maintain a constant compression pressure in the combustion chamber in the upper load range. The engine can be operated with an emulsion of fuel and water, with the ratio of fuel to water varied in dependence on the detected engine parameter(s).
