SUMMARY:

The objective of this work was to analyze the operation of a Ford SIGMA 1.6 engine, with and without ignition pre-chamber, using gasoline (E25) as fuel. For this, one-dimensional numerical simulations were carried out with the GT-POWER software. These simulations allowed the calibration and validation of numerical models, based on experimental data obtained in dynamometric tests. Predictive and non-predictive models were created, which were validated with experimental data and subsequently used to evaluate the performance of the system using the pre-chamber in different operating conditions. The models presented consistent results, with errors of less than 5% in relation to experimental data. The results showed gains in fuel conversion efficiency and, consequently, a reduction in pollutant emissions, in relation to the spark ignition engine. The predictive models created also allowed changing the pre-chamber geometry parameters such as volume and orifice diameter, allowing the study of the influence of these pre-chamber geometric parameters on fuel conversion efficiency and to minimize specific fuel consumption.
