Kubota Engine Corp., with North American headquarters in Lincolnshire, Illinois, unveiled its first diesel engine above 200 horsepower (HP) at ConExpo-Con/Agg, which took place from March 7 to 11 in Las Vegas. The five-liter V5009 is Kubota’s first model in its new 09 Series with mass production beginning in 2020, consistent with impending European Union (EU) Stage V emission regulations.
“This EU Stage V ready diesel engine has been years in the making, designed by a proactive team of engineers in Japan dedicated to researching and complying with exhaust emissions regulations around the world,” said Kevin Keyes, vice president of sales and marketing for Kubota Engine America. “Before they developed the V5009, our customers with larger application needs had to turn to another manufacturer. We received several requests for larger, more powerful engines, and are pleased to now be able to further position Kubota as one source, multiple solutions. With the new 09 Series, our customers will have a complete lineup of industrial, reliable diesel engines both below 100 HP and above 200 HP.”
The compact V5009 has an output of 157.3 kilowatts (kW) (210.9 HP) and after treatment devices including a diesel particulate filter (DPF) and selective catalytic reduction (SCR). This four cylinder engine is designed to offer outputs only available previously with six cylinders.
To achieve this output combined with low fuel consumption, Kubota’s team secured the air intake amount through high-pressure supercharging, then used combustion matching to create high in-cylinder pressure. They also designed a ladder frame structure to ensure engine durability, improved the water cooling channel and added a side power take off option and three ports for accessories such as hydraulic pumps.
“The V5009 will not require any major modifications to our customers’ current machines because it is compact enough for easy installation,” says Keyes. “It should also significantly reduce running and operating costs, saving time, money and energy for our end users.”
The 09 Series will also include a 4.3-liter diesel engine using the same next-generation platform, also available in 2020.
