Inside development of unimore's high-performance formula sae engine

THE ADOPTION OF A SINGLE-CYLINDER ENGINE, INSTEAD OF THE MORE POWERFUL INLINE FOUR CYLINDER, REQUIRED A MUCH BIGGER EFFORT FOR GETTING AN ACCEPTABLE LEVEL OF POWER.

FORMULA SAE AND ITS EQUIVALENT in the U.K. named Formula Student are competitions among university students who have to design, build, and race a car complying with specific rules issued by SAE International. The final classification of the competition derives from the sum of the scores achieved in the single events, which are divided into statics (design: 150 points at maximum, cost: 100 points, and presentation: 75 points) and dynamics (acceleration: 75 points, skid pad: 50 points, and endurance: 400 points).

As far as the engine is concerned, the technical regulations require one or more four-stroke engines running on gasoline or E85 with a total displacement not exceeding 610 cm³, and the air for all engines must pass through a single air intake restrictor. This restrictor is circular in shape and placed between the throttle and the engine(s). The maximum restrictor diameter is 20 mm (0.79 in) for gasoline fueled cars and 19 mm (0.75 in) for E85. Any device that has the ability to throttle the engine downstream of the restrictor is prohibited.
