Yanmar Co., Ltd.

The Netherlands, 29th August 2019. At the next Agritechnica in Hanover on the 10th-16th November YANMAR will show the complete line-up of its renowned diesel engines with special attention given to the newest high-power industrial engines, the 4TN101 and 4TN107. Introduced at Intermat 2018, the EU Stage V TN series will now be shown for the first time in its agricultural configuration complete with its after-treatment system, mounted on the 4TN101. YANMAR can be found in Hall 16, stand C54.

The new TN series combines durability and robustness with class-leading low fuel consumption and high power density. Thanks to YANMAR’s advanced combustion technology coupled with its optimized turbocharging application, the 55-155 kW engines have an excellent power/torque ratio to meet the requirements of a wide variety of industrial fields, including the heavy work in agriculture, construction and materials handling. Both engines are particularly suitable for agricultural tractors and other farming applications such as telescopic handlers.


The new 3.8-litre after-cooled, turbo-charged common rail engine produces 55-105 kW and 550 Nm of torque. This engine will be on display in its tractor configuration with a mounted DPF. Its compact profile and high performances have already caught the attention of several agricultural OEMs. Serial production start is planned for 2021.


The new 4.6-litre after-cooled, EU Stage V-compliant, two-stage turbo-charged common rail engine peaks at 155 kW while achieving a maximum torque of 805 Nm. This model will be shown in its tractor configuration with a bespoke DPF. By the end of 2019 the first serial production models will roll out of YANMAR’s highly automatized factory in Japan.

Main features:

(1)Best-in-class fuel consumption
By implementing YANMAR’s advanced combustion technology, which has been optimized through years of manufacturing industrial and marine diesel engines, the engines achieve fuel consumption reductions of approximately 10 percent 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.

(2)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.

(3)Outstanding torque
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 materials handling. Furthermore, the 4TN107 with a two-stage turbocharger can achieve a maximum torque of 805Nm.

(4)Compact size
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.

(5)Maximise uptime
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 the experience of 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.

(6)Wide power range
The 4TN101 and 4TN107 produce outputs ranging from 55 to 105 kW and 90 to 155kW, allowing customers to utilise their engine in a wide range of machinery with various output needs.

※1 Based upon the comparison of average industry standards with our test results.
※2 Power Density is the power output (kW) per displacement (litre).
※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 utilises ammonia generated from urea water to deoxidise, cleanse and detoxify NOx contained in the exhaust gas.


With beginnings in Osaka, Japan, in 1912, YANMAR was the first to succeed in making a compact diesel engine of a practical size in 1933. Moving on, with diesel engines as the cornerstone of the enterprise, YANMAR has continued to expand its product range, services, and expertise to deliver total solutions as an equipment manufacturer. As a provider of small and large combustion engines, agricultural machinery and facilities, construction equipment, energy systems, marine, machine tools and components – YANMAR’s global business operations span seven domains.

On land, at sea, and in the city, YANMAR’s mission of “providing sustainable solutions focused on the challenges customers face, in food production and harnessing power, thereby enriching people’s lives for all our tomorrows,” stands testament to YANMAR’s determination to providing us with “A Sustainable Future.”
