Tuning for FSAE Engine with a Supercharger 2015-32-0838
Kinki University formula project has been participating in the student Formula SAE of Japan (JSAE) every year for the Competition since the second time. The engine uses ZX-6R made by Kawasaki Heavy Industries for the Competition from the eighth time. “Improvement of limited performance” is inserted in the concept through the development of a power train. Supercharger loading, engine dry sump and engine cooling management were improved.
59.6 kW (80.6 PS) /9000 rpm of maximum output and 70.6 Nm (7.2 kgf m)/8000 rpm of maximum torque were achieved by the supercharger loading. We succeeded in getting 90% of torque band (4000∼10000rpm) by 50% of the number of revolutions in regular use (2000∼12000rpm).
Using the dry sump system, hydraulic pressure constantly managed hydraulic pressure at the time of engine operations; the system, where the engine stops at the time of hydraulic pressure fall, was also built. It was possible to lower the engine loading location by dry sump at 80 mm, and we contributed to the lower center of gravity of the vehicle. Even when the engine was not in motion by making the water pump electromotive force, it was possible to make it circulate through cooling water; it was possible to establish a cooling system in accordance with the Competition.
