Abstract The paper presents a research on the fuel injection and atomization depending on the thermodynamic quantities inside the cylinder of a combustion engine. With the use of piezoelectric outward-opening injectors the changes in the geometrical quantities of the atomized fuel in the aspect of its injection were determined. The studies concerning the influence of the individual quantities on the fuel spray penetration injected by the outward-opening injectors comprise a synthesis of the injection and atomization tests. Own mathematical equation describing the fuel spray penetration was proposed. The exponents (equation coefficients) related to the influence of the fuel pressure, air backpressure, charge density and time of fuel spray development were determined with the coefficient of determination 0.9797, indicating a congruence of the experimental data with the values obtained on the basis of the mathematical equation.
