Super Mini Series diesel engines
The Kubota Super Mini Series has been chosen as a power source for a variety of applications since it was first launched 25 years ago. It has become the benchmark in the compact diesel engine market.

• Cleaner Emissions - Compared to conventional Indirect Injection and Direct Injection engines in the same class, Kubota's Super Mini Series has attained cleaner exhaust thanks to E-TVCS (Three Vortex Combustion System--Kubota's highly efficient combustion system produces an ideal air/fuel mixture by creating 3 vortexes in the combustion chamber. This results in better cross flow of air and exhaust gases, lower air intake temperature, and improved combustion efficiency.)
• Low Noise - Noise levels during load and no-load operations are kept to a minimum with Kubota's renowned low-noise diesel engine technology and E-TVCS.
• Large Capacity, High Speed Flyweight Governor - Instead of the conventional ball type governor, a large capacity, high speed flyweight governor is used. This ensures stable operation at a low revolution speed, and assures a high torque rise, and Steady State Governor Regulation.
• Quick Start Ups - "Quick Glow" system comes as standard equipment to shorten preheating time and quicken engine start up in cold temperature.
• Highly Reliable Engine - Based on Kubota's original sturdy design, the engine promises great reliability and long service life with advantages to meet most any application.
• Accessories / Options -A full range of accessories / options are available to meet customer's requirements.

• Large Capacity, High Speed Flyweight Governor - Instead of the conventional ball type governor, a large capacity, high speed flyweight governor is used. This ensures stable operation at a low revolution speed, and assures a high torque rise, and Steady State Governor Regulation.
• Quick Start Ups -"Quick Glow" system comes as standard equipment to shorten preheating time and quicken engine start up in cold temperature.
• Highly Reliable Engine - Based on Kubota's original sturdy design, the engine promises great reliability and long service life with advantages to meet most any application.
• Increased PTO Capacity for Beltdrive - The crankshaft has sufficient diameter, strength and main bearing area to meet various applications and to handle heavy loads.
• Accessories / Options - A full range of accessories / options are available to meet customer's requirements.

07 Series diesel engines
The new Kubota 07 Series engines have been designed to comply with EPA Interim Tier 4 (Option1) emissions regulations, which are the most stringent in this size range. The Kubota 07 Series engines also comply with EU Stage lllA 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.

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 and superior endurance.

V3 Series diesel engines
Kubota presents the world's first E-CDIS (Centre Direct Injection System) type combustion system diesel engine. This advanced 4-valve system is made exclusively for the V3 DI series. The engines are available as normally aspirated or turbocharged. They have achieved higher output, higher torque rise and cleaner emissions.

The Kubota V3 series engines are new high power density engines with the same footprint as the V3300 engine, however with a larger displacement.

Kubota's original E-TVCS (Three Vortex Combustion System) has been improved. The airflow, combustion chamber and piston recess were optimized to provide a 25% lower particulate matter (PM) level, resulting in a better condition compared to engines that only meet EPA Tier 3 regulations in this class.
