Professional multifunction brushcutter ST 50 evolution

The significant amount of clean air entering from outside through the two separate intake ports and accumulated in the cylinder’s transfer passages improves the engine’s scavenging phases, which are therefore carried out with fresh air.

This process ensures a drastic reduction in outgoing HC (unburned hydrocarbons).

• very low pollutant emissions
• reduction of up to -80% of HC from 40,000 ppm to 8,000 ppm
• significant increase in torque and power (up to +30%)
• substantial reduction in fuel consumption (up to -20%)
