Yanmar has developed two models of high-powered industrial diesel engines (3TN86CHT/4TN86CHT) that comply with EU Stage V and U.S. Tier 4 emission regulations.
The newly developed engine pursues higher power density by integrating the latest diesel engine technology born from Yanmar’s extensive engine development experience. In addition to complying with strict emission regulations, the new engine is compact, allowing it to be fitted to customers’ machinery and has lower fuel consumption and noise, according to Yanmar.
Yanmar has added high-powered new models to its popular line-up of vertical water-cooled diesel engines for industrial use and will continue to provide power sources for industrial machinery that meet customers' requirements.
To increase power output, a new turbocharger matching design has been implemented, along with higher strength in various engine parts. As a result, 3TN86CHT and 4TN86CHT have 20 percent and 14 percent more power output, respectively, than models of the same displacement with intercooled turbo in the current line-up.
The compact outline of the engine was designed in consideration of engine bay dimensions, making it easier for customers to install it on their work equipment. In addition, increasing the output of the exhaust gas after-treatment system without making it larger contributes to improved operator’s visibility and comfort. The new engine is equipped with Yanmar’s proprietary DPF system for capturing particulate matter. The DPF cleaning service has a long interval of 6,000 hours.
