 note = {J-GLOBAL ID : 200901007217026264, J-GLOBAL ID : 200901026163646061, Student Formula Japan is one of the competitions of the manufacturing education for students, which is held by SAE (Society of Automotive Engineers). The competition consists of the static events and the dynamic events. The static events have three competitions of presentation, cost and design, and the dynamic events are acceleration, skid pad, autocross and endurance with fuel consumption. To get the higher rank in this competition, we must win the dynamic events with the high allotment points. For the purpose of the winning, we should have some advantages more than the other universities. We aimed at raising engine power and drivability. There are some ways to get engine power up such as the combustion improvement, the change of the cam profile and supercharging. We tried to install a commercial turbocharger to a normal aspirated multi-cylinder engine for Student Formula Japan under the SAE regulations. As the throttle and air restrictor must be located at upper streamside of the intake system, the piping from the exhaust manifold to the turbocharger is designed in order not to flow fuel into the turbocharger. Furthermore, we redesigned the intake air collector and the air restrictor in consideration of installation of the turbocharger to the standard engine. We considered sufficiently the results of the simulations using VES (Virtual Engine Simulation) and CFD (Computational Fluid Dynamics) simulation methods and verified them by the results of the experiments. As a result, we succeeded getting the higher engine performance by turbocharging than the normal engine, and the turbocharged engine can perform the higher and flat torque in the lower engine speed range, 5000［r/min］to 8000［r/min］. We made a Student Formula Japan vehicle that everyone can drive fast., application/pdf},
