Features At A Glance
Fuel Flexibility
The installation compatibility that exists between Spark-Ignition engines (SI) and Compression-Ignition engines (CI) is convenient for customers who need fuel flexibility for their products. The Kubota WG1903 includes gasoline, LPG, and natural gas versions, as well as dual fuel (gasoline and LPG) version.Durability and Reliability
Kubota WG1903 SI engines are designed after Kubota 03 Series diesel (CI) engines. While keeping the same footprint as the D1803 diesel engines, they offer performance similar to that of our turbo diesel engines, which are known worldwide as reliable industrial engines. The Kubota WG1903 engine offers very low vibration and extremely low noise as well.
