Engine/Vehicle Matching for a FSAE Race Car 2007-01-3541

In this paper a simple method to support the selection of the engine of a FSAE race car is presented. The rules impose to use a 4T engine with a maximum displacement of 610 cc breathing from a 20mm restrictor inserted downstream to the throttle body. The rules impose also the acceleration mission of the engine vehicle system: 75m acceleration test and 77m maximum length of straight lines if included between two 9m radius hairpins. An integrated model that consider restricted engine torque, drag and rolling losses and vehicle mass is presented and used to evaluate the system performances in the acceleration mission for several engines.
