Top manufacturers of compact diesel engines, known as the first manufacturer to adopt US CARB ULGE emission regulations * for engines under 19 kW (25 hp). Kubota manufactures industrial engines with diesel, petrol and gas engines (LPG and NG) in the power range of 86.4 kW (115.86 hp). In addition to a wide range, Kubota has added a new series called 09 to its program, which includes 157.3 kW (210.94 hp) diesel engines. The biggest advantage of the Kubota engine is the technology that responds to environmental requirements and application engineering. Since receiving the CARB Emissions Regulations (California Air Resources Board, USA) in 1993 as a manufacturer of small industrial engines, they have always followed strict emission controls around the world as pioneers of environmental technology. Today, they are expanding production to optimal locations around the world for fast and timely delivery of engines to global equipment manufacturers (OEMs). In 2014, in addition to the factory in Thailand, they also started production in China, where the integrated production process covers the entire process. From casting to casting and engine making. They will continue to strive and build a reputation for quality around the world.

The reason Kubota can answer such a wide range of machinery needs in the world is that we offer so many kinds of engines. We have been involved in R&D for many years, and we take pride in the fact that we can make any kind of engine. What's great about engines is that they can produce power easily and can be used anywhere. And engines will continue to transform, from mere machines to mechanical systems. We exchange opinions with professionals from all fields of science in our thorough pursuit of quality. The ultimate dream we are working towards is to someday achieve a “true zero emissions engine” that also produces zero heat, noise, and vibration, and we will continue our work toward that goal.

What is a Kubota Engine?
Kubota engines are general-use engines produced by the Kubota Group. Kubota engines, which were born from casting and mechanical technology, were later installed in Kubota’s own agricultural and construction machinery, among similar devices, with the engines themselves ultimately being sold externally or offered via OEM, making Kubota a top manufacturer of general-use engines. Now, Kubota has a leading share of the global market for small industrial diesel engines. Kubota Engine has continued to manufacture engines that conform to the environmental regulations of each region around the world, and enjoys high popularity among agricultural equipment manufacturers globally.

Petrol powered engines

Kubota's petrol engine power range extends from 4,1 kW to 65,0 kW.

In this category you will find one, two, three and more cylinder engines that can be petrol, gas driven or in combination of those two. Engines are naturally aspirated or turbocharged, mechanical or electronically controlled suitable for different types of applications.

The Kubota V5009-CR-T-E5 is Japan's first engine, which received the prestigious award and earned the title of DIESEL OF THE YEAR in 2019. Kubota designed a new series called with this engine 09 Series, where it is in the company with the engine V4309 (115.7 kW) and S7509 (228.4 kW). The compact 4-cylinder engine achives the high power output and low fuel consumption with combustion precise chamber optimization. With the help of DOC, DPF and SCR systems, it achieves the strict EPA / CARB Tier 4 regulations and EU Kubota Stage V logo .

Development

As awareness of preserving the global environment increased, regulations on emission standards also tightened. All manufacturers of industrial machinery marked with the abbreviation OEM must have the appropriate emission certificate for their product according to the required level. At Kubota, they have gone into the power range of engines up to 200 hp that meet Stage V emission regulations, because they want to help all manufacturers with fast and carefree installation of the drive in the machines.

Protecting the environment

The new V5009 engine has been developed at Kubota to meet the latest and most stringent emission regulations in the US, Europe and Japan. The Stage V regulation came into force in 2020, which Kubota was ready for, as it has many years of experience in the production of engines with diesel particulate filters (DPF). The V5009 has been upgraded with a SCR system and is ready for Stage V regulation with a cleaner exhaust.

Development aims to electrify powertrains, so you can expect great benefits in the future from combining fossil fuel engines and electrical components. At Kubota they designed a generator for its engines and named it it "Micro Hybrid Technology" to target upcoming industry trends.

What is Micro Hybrid Technology?
Kubota Micro Hybrid Technology is a system installed with a 48-volt motor generator – in place of an alternator – using electric power only when intermittent overloads need to be handled. A motor-assist function is used to supply 10kW of electrical boost power when needed for intermittent "big" loads, so you can select an engine with output to match the frequently used low to medium load range, together with electric power to compensate for infrequent intermittent overloads. You don't need to rely upon a large displacement engine for your peak power anymore. Micro Hybrid brings more flexibility and better efficiency to industrial machines.

Fuel Consumption

With the help of technology, machine developers (OEMs) can install smaller engines in terms of configuration and configuration without a lack of power output. The choice of a smaller engine has a positive effect on fuel consumption.

Ideal for

Applications that require intermittent overloads such as forklifts, road rollers, sweepers and other non-highway machines used in work sites. Until now, the only choice available was a large engine for handling intermittent overloads which make up only a fraction.

For all fuel types

Consistent with the Kubota electronically controlled engine (ECU), the Micro-Hybrid technology is designed to be compatible across our fuel range.

Minimal adaptations

As Kubota Micro Hybrid technology does not interfere with power take-off positions on the engine, it can be applied to existing applications and applications under development as well. And you can count on Kubota to propose the necessary parts as a package to convert your engine to Micro Hybrid. There’s no need to make any design changes to your machine.

Lower cost

Since it uses a motor generator which provides 10 kW of electrical boost power when needed for intermittent “big” loads, it means that you can downsize your engine while maintaining the same level of performance of a larger engine.

Micro Hybrid technology offers a smaller engine more flexibility and better efficiency to industrial machines than an engine equipped with a classic alternator.

In modern times, quick recognition of potential complications is key. At Kubota, they have developed the "Engineering Telematics" system, which quickly assesses the condition of your electronically controlled engine with a common line and provides you with an assessment of the condition, possible support, optimization and notification of service intervention of your drive. Within three simple steps, you can connect the module to your engine, which will take care of reading basic data, print out and save key parameters directly in the computer cloud. With the help of the information, you can plan regular services, check the condition of your engine and study the measured data. Currently, the system is only available in certain Kubota models, if you would like more information, please contact us.
