Summary:

The growing global need for energy and the aggravation of vehicular pollution, associated with a highly competitive market, demand fast and less expensive solutions to develop engine technologies. Numerical simulation has been an effective tool to help meet these needs, as it shortens the time and cost of current engine research. In this scenario, 1-D numerical model has been widely and successful used, presenting excellent results generally with errors around 5% in comparison with experimental data. In this work, the main performance parameters of an in-line four-cylinder SI engine is analyzed through a 1-D simulation using the GT-Power code. A full-scale engine model is set up, which is later calibrated by comparing with experimental data. The numerical methodology is carefully discussed and the methods regarding engine valve diagram and geometrical boundary conditions are also presented. Numerical results of engine power, torque, volumetric efficiency and specific fuel consumption are presented with maximum errors no greater than 7%
