PERFORMANCE CURVES
FEATURES and BENEFITS
Emissions
The D1803-M engine complies with the EPA / CARB interim Tier
4 + EU Stage IIIA emissions regulations.
Durable Power
The Kubota 03-M Series is well known for its industrial applications.
With numerous features such as a built-in solenoid, low fan position,
and single-side serviceability, this engine provides excellent
performance and flexibility.
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.
The D1803-M engine offers a seamless transition from EPA Tier 2
to Interim Tier 4 by maintaining the same footprint and hardware
mounting points with minimal performance changes from Tier 2
engines.
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 lower particulate matter
(PM) levels.
The half-float valve cover and MoS2-coated pistons reduce noise
levels compared to conventional diesel engines and decrease
vibrations transmitted from the valve area.
Options
Kubota 03-M Series engines offer side power take-off (PTO) in
response to the trend of the use of hydraulic control devices in
industrial machines. A hydraulic pump can be installed at the two
side PTO locations.
