The Automotive Engine Modeling for Steady-State Condition Using FORTRAN/GT-POWER
Journal Title: International Journal of Automotive Engineering and Technologies - Year 2015, Vol 4, Issue 3
Abstract
The increasing complexity of modern engines has rendered the prototyping phase long and expensive. This is where engine modelling becomes in the recent years extremely useful and can be used as an indispensable tool when developing new engine concepts. The purpose of this work was to provide a flexible thermodynamic model based on the filling-and-emptying approach for the performance prediction of a four-stroke turbocharged compression ignition engine. To validate the model, comparisons were made between results from a computer program developed using FORTRAN language and the commercial GT-Power software operating under different conditions. The comparisons showed that there was a good concurrence between the developed program and the commercial GT-Power software. The range of variation of the rotational speed of the diesel engine chosen extends from 800 to 2100 RPM. By analysing these parameters with regard to two optimal points in the engine, one relative to maximum power and another to maximum efficiency, it was found that if the injection timing is advanced, the maximum levels of pressure and temperature in the cylinder are high.
