Kohler Engines introduced its 3.4-liter KDI 3404 engine at World of Concrete in Las Vegas this week. The engine is designed for heavy-duty commercial application. It’s a Tier 4 Final engine that offers optimized fuel consumption without the use of a diesel particulate filter.
“This is the most powerful engine we’ve ever manufactured,” said Jeff Wilke, product manager for diesel engines for Kohler. “It’s an ideal power source for larger commercial applications in the construction, industrial and agricultural markets.”
Kohler’s KDI line includes Kohler’s direct-injection system, cooled exhaust gas recirculation and diesel oxygenated catalyst. A high-pressure common rail system utilized pressures at 2000 bar (29,000 psi) to deliver better atomization of fuel, improved consumption and a reduction in emissions. The KDI 3404 is available in four ratings, ranging from 74 to 134 hp.
The engines are manufactured in Kohler’s diesel production facility in Reggio Emilia, Italy.
