Engine calibration and development process needs more optimized products due to powertrain performance
improvement, financial competition and technical challenges. Nowadays, it is possible to use one
dimensional tools on many purposes, such as in order to reduce development/calibration time and cost ,
examine the effect of many parameters on each other, integrated model setup for with HIL (hardware in
the loop) or SIL (software in the loop) systems. Therefore, one dimensional engine modeling play a critical
role in engine development process.
In this study, engine to be analyzed, 4-cylinder 600 cc naturally aspirated port injection Otto engine which
is used in a Formula Student Race Car. GT-Suite was used as an one dimensional analyze software which is
commonly used in the sector. GEM 3D software which is sub-software of GT-Suite, has been used for air
path modeling. Air intake and exhaust paths are modeled and reduced to one dimension. The geometric
variables such as diameter and length of the parts are parameterized in order to optimized the geometry
to more efficient engine. Engine model has been correlated in terms of test data. After engine model
correlation, intake runner lenght and diameter, intake and exhaust valve timing were determined to obtain
best fuel consumption without exceed exhaust gas temperature limits at base model. A better performance
and and fuel consumption was obtained with using model approach compared to the base set up and
calibration.
