Yanmar’s new diesels offer high power density and low fuel consumption

Yanmar’s two latest diesels, the 4TN101 and 4TN107, are said to combine high power density with low fuel consumption. According to Carlo Guidici, sales director for Yanmar Europe: “The engines have 10% lower fuel consumption than the average for the competition.” With power outputs ranging from 90-155kW, the 4.6litre 4TN107 can provide a power density of 33.7kW/litre, which the firm claims is the highest in its class, while it delivers 805Nm of torque.

Yanmar’s latest diesels combine fuel economy with high power output

7139 Yanmar’s two latest diesels, the 4TN101 and 4TN107, are said to combine high power density with low fuel consumption. According to Carlo Guidici, sales director for Yanmar Europe: “The engines have 10% lower fuel consumption than the average for the competition.”

With power outputs ranging from 90-155kW, the 4.6litre 4TN107 can provide a power density of 33.7kW/litre, which the firm claims is the highest in its class, while it delivers 805Nm of torque.

The issue of power density is important and Guidici commented: “A bigger machine can be powered by a smaller engine.” He added that this means that for some installations, the 4.6litre unit will be able to take the place of 6litre engines.

The 3.8litre 4TN101 meanwhile offers power outputs of 55-105kW, with torque output of up to 550Nm. Both units are said to be compact in design, allowing them to be installed in existing machines with minimal design changes.

The units are also said to be durable and dependable. And Guidici said: “They offer reliability under every operating condition as well as low operating costs.”

Low emissions performance is delivered due to a two stage regeneration system, which the firm first introduced 10 years ago and has continued to fine tune to improve performance. Because this system is well-proven, Yanmar claims it is highly reliable and durable and is able to meet the latest emissions regulations.

Other proven technologies include the high pressure fuel injection system operating at 2,000bars, which Yanmar has developed completely in-house. This system helps to optimise combustion, providing the low fuel consumption and high torque and power outputs for each unit.

    Case CE is offering revamped graders that feature increased performance in the shape of its latest 836C and 856C models. Power comes from diesels supplied by sister firm FPT Industrial, which deliver high power and torque for low fuel consumption and feature proven and patented SCR after-treatment technology to deliver low emissions. As the engines have no Diesel Particulate Filter (DPF), this reduces complexity and helps to cuts running costs, while they meet the Tier 4 Final requirements.
