The Hyundai Infracore group’s engines, a South Korean giant well-established in the earthmoving segment, are aiming to expand into the agricultural mechanization sector. Over the past few years, the company has targeted agriculture and showcased a broad range of engines at Eima this year, some of which are already integrated into the European market’s tractor segment.
At the Bologna exhibition, Goldoni Keestrack’s stand displayed three- and four-cylinder “Dm” series units in the new generation of Italian-Belgian specialized tractors. These engines power Goldoni machines, with the “Dm01” three-cylinder engine featuring a displacement of 1.8 liters, delivering 55 horsepower and 190 newton meters of torque, and the “Dm02” four-cylinder engine with a displacement of 2.4 liters, capable of delivering up to 105 horsepower and 310 newton meters of torque.
However, the real innovations were the launch of the new “Dx5” and “Dx8” engines, which had previously debuted in the construction segment and in Europe earlier this year at Intermat in France. These are medium to high-power engines designed to power large machines and generators.
The “Dx5” is a four-cylinder engine with a five-liter displacement, defined by bores measuring 110 mm and strokes of 132 mm. It delivers a peak power of 171 kW (about 230 horsepower) at 1,900 rpm, paired with 955 newton meters of torque starting at 1,400 rpm. In genset applications, the “Dx5” offers standby mechanical power of 200 kW at 60 Hz and 183 kW at 50 Hz, which decreases slightly to 197 kW and 177 kW respectively in prime power configurations. The engine complies with Stage V emissions standards, featuring an after-treatment system integrating DOC, DPF, and SCR filters, and is certified for use with HVO fuel.
The same solution applies to the “Dx8,” which shares the bore geometry but features a six-cylinder architecture, offering a total displacement of 7.5 liters. The “Dx8” delivers a maximum power of 254 kW (just under 350 horsepower) in off-road applications, achieved at 1,800 rpm, with 1,460 newton meters of torque starting at 1,200 rpm. For power generation applications, it provides 307 kW of standby mechanical power at 60 Hz and 290 kW at 50 Hz, with prime power outputs of 279 kW and 264 kW, respectively.
To demonstrate its readiness for large-scale implementation, Hyundai also showcased the “Xh12 Hydrogen” unit in Bologna. This is an 11-liter six-cylinder hydrogen combustion engine currently developed for power generation applications. Built with bores of 123 mm and strokes of 155 mm, the engine offers 282 kW of standby mechanical power at 60 Hz and 256 kW at 50 Hz, with prime power outputs of 226 kW and 205 kW.
It should be noted that the development of the “Xh12 Hydrogen” is not limited to power generation but also targets applications in the truck and bus sectors. Thanks to the hydrogen fuel’s ability to significantly reduce emissions, this unit could meet future emissions regulations across various industries.
