Mitsubishi S4S Series (39.5-74 HP) Industrial Engines
Product Description
Mitsubishi S4S Series (39.5-74 HP) Industrial Engine
This engine combines low noise and exhaust levels with excellent power capacity. Low noise and low exhaust are becoming increasingly important factors, especially for machines that operate in urban areas, particularly residential areas, during the night and indoors; this is the engine for urban work in the future. Clean emission.
