The article presents results from numerical studies evaluating one-dimensional mathematical model (MM) with single-phase I.I. Vibe combustion law for dual fuel (DF): diesel (D) and natural gas (NG) engine energy experiment. Adequacy criteria were established for high speed 4ČN79,5/95,5 engine with conventional fuel system, engine was tested on D100 and D20/NG80 fuel, in high (HLM), medium (MLM) and low (LLM) engine load modes, changing diesel injection angle (DIT) from −1 to −13° CA BTDC range for each load. The simulation of single-phase I.I. Vibe’s law of combustion is characterized by limited application possibilities. The rationality of single-phase model use was determined only in HLM engine mode (with error 7%). In the MLM and LLM regimes, the mismatch between real bi-phasic combustion with highly dispersed natural gas NG diffuse during second phase modelling error is 50%.
