This paper presents a new 4-lobe blower for supercharging a two-stroke engine. Based on a modified Roots compressor manufactured prototype shows pros and cons of an innovative profile. The results demonstrate that the shape of rotor edges effect out pressure stability. The measurement results include the main assessed parameters: outlet pressure, overall efficiency, losses and outlet air temperature.
