PERFORMANCE CURVES

FEATURES and BENEFITS

Emissions

Kubota’s WG2503-L-E3 engine has been designed to comply
with EPA Tier 2 / CARB Tier 3.

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 WG2503 includes gasoline, LPG, and natural gas versions,
as well as a dual fuel (gasoline and LPG) version.

Durability and Reliability

Kubota’s WG2503 SI engines are designed after Kubota 03 Series
diesel (CI) engines. While keeping the same footprint as the
V2403 diesel, they offer performance similar to that of our turbo
diesel engines, which are known worldwide as reliable industrial
engines. The Kubota WG2503 engine offers very low vibration
and extremely low noise.
