Kubota Engine America is exhibiting the newly announced S7509, a high power density, 300 hp, large displacement industrial diesel engine, at CONEXPO 2020. The new addition to Kubota’s 09 Series was announced by Kubota Corporation at the company’s headquarters in Japan on March 2, 2020. 

Kubota has started the development of this new large displacement industrial diesel engine, which will comply with EU Stage V emission regulations. “Kubota integrates state-of-the-art design to produce high performance and durability in all of our engines and the S7509 will be no exception,” says Tomokazu Matsushita, President of Kubota Engine America. “The S7509 will further expand the 09 series and Kubota’s goal is to become the number one supplier of engines up to 300 hp.” 

The compact 7.5 liter, 6-cylinder engine possesses low fuel consumption with its optimized, direct injection combustion system. It provides 100% power take-off at the flywheel and fan side, as well as selection of flywheel housing and flywheel for OEM coupling. The S7509 provides great versatility because the exhaust side auxiliary PTO takes up to two hydraulic pumps in addition to the intake side PTO. The engine also features a one-side easy maintenance and automatic belt tensioner. Mass production of the S7509 will begin in 2023. 

Kubota Engine America is also featuring a prototype of its Micro-Hybrid System. It is making its debut in North America at CONEXPO 2020. Kubota’s Micro-Hybrid System provides power assistance instantaneously during peak overloads to the engine providing an additional electrical power boost of up to 10 kW. The immediate torque available offers an efficiency boost at the most crucial time while recuperating and recharging its battery pack when not initiated. Kubota first demonstrated its concept at Intermat, in France on April 2018. In 2019, at bauma, Kubota displayed the prototype system installed in a forklift. The Micro-Hybrid System started with the 1.8 L engine and now it has expanded to a larger 3.3 liter engine. The peripheral key components, such as DC-DC converter and 48V lithium ion battery have also been enhanced.

“Kubota’s Micro-Hybrid System allows for engine downsizing yet maintaining performance, productivity and efficiency,” says Matsushita of Kubota Engine America. 

“The enhancement of the lineup will provide benefits to more OEM customers and equipment users,” says Matsushita. 

In addition to all the new engine products, Kubota Engine America is also launching its service mobile application at CONEXPO 2020. The app can connect users to an engine service dealer, while also providing product registration and a knowledge center with resources on maintenance schedules, operation manuals and warranty information. 

Kubota Engine America’s display at CONEXPO 2020 rounds out one of the largest and most comprehensive range of diesel and spark ignited engines, new engine technology as well as aftermarket support. Kubota will be located at booth S84914.
