Feature - Kubota WSM 07-E3B Series Workshop Manual

07-E3B SERIES, WSM

1. FEATURE

The 07 series DI engine are the vertical type 4-cycle
diesel engine featuring the advanced performances
shown below.
 New Concept
• The Kubota 07 Series is a totally new concept in
engine design developed with various requirements
necessary for a wide range of industrial applications.
• Kubota's unique cylinder block design was developed
using Kubota's original casting technology allowing
for a larger displacement within the current 2.4 L
compact engine package.
• The improved cooling system with a main water
gallery and water passages between cylinder bores
as a countermeasure against heat load provides high
power density, superior endurance and a reliable
Kubota 07 Series.
• The Kubota 07 Series completes Kubota's seamless
range up to 100 hp.
 Emissions
• The NEW Kubota 07 Series engines have been
designed to comply with EPA Interim Tier 4 (Option 1)
emissions regulations, which are the most stringent in
this size range. The Kubota 07 Series engines also
comply with EU Stage A requirements. The Kubota
07 Series engines offer the benefit of one year longer
validity than Tier 3. Therefore, these engines are
good through the end of 2012 in both the North
American and European markets, which would save
engineering resources for the future Tier levels.
• Meeting emission regulations with minimal additional
required devices : NOx is reduced only by mechanical
means such as a compactly designed cooled exhaust
gas recirculation (EGR) system.
 Clean and Quiet Power
• Kubota's original E-CDIS (Center Direct Injection
System) combustion system, renowned for clean
combustion in the Kubota V3 (DI) Series, has been
renovated. The fuel injection pressure was increased
and the combustion chamber was redesigned to
achieve a 25 % lower particulate matter (PM) level,
resulting in a better condition when compared to
engines that only meet EPA Tier 3 regulations in this
class.
• These new engines have been designed to reduce
transmitted vibrations and radiated sound, resulting in
lower noise levels.
friendly, the Kubota 07 Series begins a new era of
Kubota's engine design.
