Kubota Engine America (Kubota) will exhibit its sustainability developments during CONEXPO-CON/AGG (CONEXPO) 2023, led by the 3.8-liter hydrogen engine. The company will feature new engine developments using carbon-free fuels, hybrid engine solutions and engines with greater fuel efficiency, which are all part of Kubota’s initiatives to reach a carbon-neutral future.
Kubota will display the newly developed, 3.8-liter hydrogen engine. Similar to gasoline engines, the 3.8-liter hydrogen engine offers spark ignition at 85 kilowatts (kW). Specifications of the engine include 3.8 liters and four cylinders for multiple applications, making it a great alternative-fuel solution.
Along with the hydrogen engine, Kubota announced last year that all Kubota diesel engines in Europe were approved to use paraffin-based fuels that comply with European standard EN15940. This permits the use of gas to liquid (GTL) and hydrotreated vegetable oil (HVO) fuels complying with the standard, enabling a reduction in carbon dioxide (CO2) emissions of up to 90% with no engine modifications needed. To expand on this, Kubota announced that the use of HVO is also approved for use in Kubota diesel engines in the U.S. This announcement further underlines the company’s commitment to a carbon-neutral future as HVO and GTL offer a range of environmental benefits compared with conventional fuels.
Kubota also announced the D1803 P1 Hybrid engine. This engine is compact and robust with an integrated motor generator embedded within the flywheel housing. With the P1 Hybrid engine, the motor only assists for the brief periods in which high output is required. Additionally, necessary components are provided by Kubota, so customer development resources can be kept to a minimum.
The switch between engine and electric motor drive will also occur with Kubota’s D1105 P2 Hybrid engine. The engine was first introduced at the bauma 2022. However, Kubota will introduce it to the North American market at CONEXPO.
Offering a rated output of 28.4 hp (18.5 kW) at 3,000 rpm, the D1105 P2 Hybrid also offers the ability to transition between diesel engine drive and electric motor drive while in operation. In areas where emissions and/or noise are a concern, the engine can be stopped, and the electric motor used. The start of production on the D1105 P2 Hybrid is scheduled for 2025.
Kubota will also feature its V3307 Micro-Hybrid engine, which will be in production later in 2023. The engine has a straightforward design with three main components: a DC converter, a lithium-ion battery and a motor generator attached to the existing engine model.
Kubota believes that a hybrid system combining engine and electrical power is an effective solution for reducing CO2 from industrial engines, which require high output and high load. As of March 2023, Kubota is promoting three hybrid solutions: the newly introduced D1803 P1, the D1105 P2 and the V3307 P0 Micro-Hybrid.
The D902-K, Kubota’s first electronically controlled diesel engine under 19 kW that was introduced in 2021, will also be on display. The D902-K is a three-cylinder diesel engine with a displacement of 0.898 liter and an output of 24.8 hp (18.5 kW) at a rated speed of 3,600 rpm. Black smoke emissions have been reduced to an invisible level during startup, acceleration and sudden load because of the new TVCR combustion system.
Building off the D902-K, Kubota’s introduction of the D1105-K engine followed in 2022. Also equipped with the new TVCR combustion system, this new engine has an output of 24.8 hp (18.5 kW) at 3,000 rpm, with three cylinders and 1.123-liter displacement. The improved fuel consumption and the compactness of the D1105-K allows for simplified installation.
Along with new additions to the engine family, Kubota will also feature its first-ever diesel engine above 100 hp, the V5009 from the Kubota 09 Series. Introduced at CONEXPO in 2017, this engine was designed to meet the higher power demands and wide range of needs in construction and industrial machines. The V5009 delivers 208 hp while meeting the stringent emissions standards of EPA Tier 4 and EU Stage V.
