METHOD FOR ICE INJECTION PARAMETER ADJUSTMENT Russian patent published in 2014 - IPC F02D41/30 F02D43/00 F02D41/38 F02B75/12 F02M45/12 

FIELD: transport.

SUBSTANCE: invention relates to transport and can be used in processes of fuel combustion in internal combustion engines (ICE). In the method, both charge stratification and homogeneous air-fuel mixing is provided by means of changing at least one injection parameter. The method consists in adjustment of fuel injection depth by means of changing injection pressure. Injection depth is adjusted within total depth of combustion chamber, and injection pressure is changed either smoothly or in steps, in particular using mode selector. Mode selector provides at least two fixed charge stratification modes with possibility of their selection or switching between them. Herewith, within used modes the injection duration parameter can be set in proportional dependence or in one of types of nonlinear dependence on injection pressure: differential, integral, logarithmic or any other nonlinear dependence.

EFFECT: wider range of fuel depletion degrees which improves efficiency and cleanliness of exhaust ICEs.
