The main purpose of Formula SAE Competition (hereafter called “FSAE”, “Formula Society of Automotive Engineering”) is to let students learn the basic ability necessary for engineers through design, fabrication and test projects. Higher running performance of a manufactured vehicle is one of the most important themes that should be studied in Student Formula Japan Competition (hereafter called SFJ Competition). Also, SFJ Competition is the series of the FSAE. the purpose of this study, the chassis must be required light weighting and high stiffness. The former can reduce the centrifugal force and the inertial force in the turning and the latter can contribute to demonstrate the suspension performance according to design [1], [2], [3], [4]. The SFJ Competition has Skid Pad event to compete for steerage responsiveness and high suspension performance on turning. The balance of the highly performed engine and chassis requires to keep high running performance of competition vehicle [5],[6].

A small size engine, SD01 has been developed since 1989. For the purpose of cultivating the advantageous properties of the SD01 engine, its cylindrical cam mechanism was modified. The modification was able to operate the Stirling cycle stably and silently. The modified SD01 coupled with an electric motor was reconstructed as a hermetic cooler. The attractive Stirling cooler was evaluated on the conditions of a cooling mode. Moreover, with an aid of the enhanced design concept for the SD01 machine, a small size Vuilleumier machine for heat pump applications was designed and constructed.
