PERFORMANCE CURVES

FEATURES and BENEFITS

Proven Reliability and Technology

The latest technology and strong performance-two things
customers expect from Kubota engines. We continue to provide
both of these through the pursuit of excellence in three key areas:
emissions compliance, progress towards fully electronic-controlled
engines, and flexibility in the products and services we provide to
customers worldwide.

Clean and Quiet Power

A common rail system has made it possible to optimize combustion
and create a more durable and quieter engine with higher fuel
efficiency. By meticulously screening and controlling the exhaust
gas aftertreatment components (Diesel Oxidation Catalyst [DOC]
and Diesel Particulate Filter [DPF]), we are able to offer a clean and
high-performance engine.

countries who have different engine needs. Since Kubota 03
Series engines have evolved along every step in meeting the
requirements of each EPA Tier, we are able to provide our
customers worldwide with engines certified for the appropriate
emissions regulations. In addition, we have designed aftertreatment
units with minimum impact for easy installation.
