This paper presents the effectiveness of representing process creating and burning a combustible mixture in vibroacoustic parameters compression ignition engine. Empirical engine tests allowed us to conduct analyses terms operating conditions, fuel parameters, type. The influence dimethyl ether on combustion efficiency was quantified using performance indicators, emission vibration estimates (compared diesel fuel). Mathematical models its variability were created mean, peak-to-peak amplitude, root mean square error, peak amplitudes accelerations, which also represented graphics. Dimethyl positively influenced performance, emissions, reduction. proposed method can predict irregularities detect their sources designs with high kinetic energy, hybrid modeling, composition identification. reduced hydrocarbons by 96–99%, particulate matter 37–60%, carbon monoxide 2.5–19.5%, whereas nitrogen oxides increased 1–8% (relative Emission accuracies 0.88–0.96 (hydrocarbons), 0.80–0.98 (particulate matter), 0.95–0.99 (carbon monoxide), 0.97–0.99 (nitrogen oxides). application amplitude vibrations range 5.7–60.6% 18.2–72.4%. standard deviation decreased 8.8–49.1% (mean) 28.8–39.5% (peak-to-peak). models’ accuracy scores 0.90–0.99 (diesel fuel) 0.72–0.75 (dimethyl ether).
