PERFORMANCE CURVES
FEATURES and BENEFITS
Emissions
The D1305 engine complies with the EPA / CARB interim Tier 4 +
EU Stage IIIA emissions regulations.
Durable Power
The Kubota 05 Series is an established leader in its horsepower
range, selected as the power source of choice by various industrial
equipment manufacturers. The D1305 engine is a high power
density engine that delivers the highest output within the Kubota
05 Series with a naturally aspirated 3-cylinder configuration.
By expanding the stroke, Kubota has increased engine displacement
by 12% compared to the D1105 while maintaining the same footprint.
The use of a shallow, large-capacity oil pan keeps the engine height
low, providing a compact engine package.
The cooling water passages between the cylinder bores features
Kubota’s original casting technology as a countermeasure against
the heat load caused by high power density, providing both superior
endurance and reliable engine performance.
Clean and Quiet Power
Kubota’s original E-TVCS (Three Vortex Combustion System) has
been improved. The airflow, combustion chamber, and piston recess
have been optimized to provide low particulate matter (PM) levels,
matching the stringent level of the 37 kW class and higher (EPA
Interim Tier 4 Option 1). The half-float valve cover and MoS2-coated
pistons reduce noise levels and decrease vibrations transmitted from
the valve area.
Option
A variety of engine accessory options for the existing Kubota 05
Series are also available for this engine.
