Implementation of an exponential mathematical model of power-torque curves in an algorithm for natural aspirated and turbocharged internal combustion engines
Overtaking is one of the most complex maneuvers performed on two-lane rural highways, and its associated accidents account for a large proportion of the mortality connected to traffic accidents. In addition, the number of long vehicles, such as trucks or buses, using these traffic routes is increasing significantly. On the other hand, to perform this maneuver characterized by a fast and a slow vehicle, the engine of the fast one must have sufficient elasticity to achieve the required acceleration in the high gears, and in this sense, the turbo engine can provide this performance, with small engines and fuel savings. In this work, we develop an algorithm to simulate both naturally aspirated and turbocharged engines, fitting their characteristics based on an exponential model and comparing them with those on test benches
