Abstract:
The present invention refers to a method of using lean fuel-air mixtures at all operating regimes of a spark ignition engine, which is provided with an intake port fuel injection system, wherein said method is characterized in that in order to achieve the efficient lean mixture combustion process, an HHO oxy-hydric gas direct injection should be at a minimum pressure of 10 bar, during compression stroke, after intake valve closing, so that the hydrogen/fuel mixture volumetric fractions value is within the range of about 15% to 25%.
