Test motoru 95 oktan benzin yakıtlı VSG413 SI türü motordur. Test motoru 1.3 l hacim, dört strok, dört silindir, 45 kW’lık maksimum güç kapasitesi ve 98 Nm’lik maksimum tork kapasitesine sahiptir. Deneyler tam yük test koşulları altında gerçekleştirilmiştir. Krank mili hızı 1200 d/d ve 5000 d/d aralığında değiştirilmiştir. Hesaplamalarda, deneylerden elde edilen gerçek çalışma verileri kullanılmıştır. %29.78’lik maksimum enerji verimi ve %27.77’lik maksimum ekserji veriminin 2500 rpm’lik krank mili hızında elde edildiği tespit edilmiştir. Entropi üretimi krank mili hızının artmasıyla artmaktadır ve bütün çalışma boyunca 0.059 kW/K ile 0.253 kW/K aralığında değişmektedir.
