Yanmar has developed two new high-power industrial diesel engines that produce up to 155 kW while meeting EU Stage V emission regulations, the company announced at INTERMAT 2018, one of the world’s largest exhibitions of industrial machinery. With the addition of these new engines, the 4TN101 and 4TN107, Yanmar’s lineup of diesel engines has expanded, placing the company into the heart of the high-power diesel engine market.
Industrial and marine diesel engines must meet strict emission regulations in various markets, while delivering superior fuel economy and overall efficiency with reliability and durability, to satisfy today’s customers. Yanmar has long provided a wide range of products to meet the needs of its customers and continues to do so with the two engines introduced today. The 4TN101 and 4TN107 are the result of Yanmar’s rich heritage and vast experience in developing cutting-edge diesel engine technology, and show the company’s commitment to producing the very best high-power, fuel-efficient diesel engines that the market demands.
In addition to these newly developed high-power diesel engines, Yanmar will continue to offer superior compact diesels which meet the needs of all our customers in the under 56kW class.
Best in Class Fuel Consumption
By implementing our advanced combustion technology, which has been cultivated through years of manufacturing industrial and marine diesel engines, our engines achieve fuel consumption reductions of approximately 10% compared to a similar-sized engine with the same output※1. The improvement in fuel efficiency results in longer operation times and contributes to significant financial savings throughout the life-cycle of the engine.
High Power Density
Yanmar has produced a high-rigidity engine designed for high-power output. The 4TN107 features a two stage turbocharger that gives it a class-leading power density of 34kW/L※2.
Thanks to Yanmar’s advanced combustion technology and application of the turbocharger, both engines deliver superior torque to meet the requirements of a wide variety of industrial fields, including construction, agriculture and material-handling. Furthermore, the 4TN107 with a two stage turbocharger can achieve a maximum torque of 805Nm.
The compact profile of the engine takes into account the needs of vehicle manufacturers, improving installation characteristics. Yanmar’s proprietary exhaust-gas reduction technology results in a more compact exhaust-gas after-treatment system markedly improving the outward visibility and the comfort level for machine operators.
Yanmar’s engines utilize a Diesel Particulate Filter※4 (DPF) to reduce Particulate Matter※3 (PM) and a Selective Catalytic Reduction (SCR※5) system to reduce harmful emissions. These technologies, which have been refined from our experience developing smaller engines, allow the 4TN101 and 4TN107 to comply with EU Stage V regulations. With these systems in place, our customers can continue to operate their vehicles without having to stop, even at high-altitude or in low-temperature environments, or when working with light or heavy loads.
Wide Power Range
The 4TN101 and 4TN107 produce outputs ranging from 55-105 kW and 90-155 kW, allowing customers to utilize their engine in a wide range of machinery with various output needs.

※2 Power Density is the power output (kW) per displacement (liter).
※3 PM: Refers to particulate matter, such as suspended particulate like soot.
※4 DPF: A Filter device designed to remove particulate matter (PM) from diesel exhaust.
※5 SCR: The Urea SCR (Selective Catalytic Reduction) system utilizes ammonia generated from urea water, to deoxidize, cleanse, and detoxify NOx contained in the exhaust gas.
