Cummins achieves stage V certification with B6.7 and L9 engines

Cummins has announced that its latest B6.7 and L9 engines are fully EU Stage V emissions certified and in full production at its Darlington engine plant in the UK. “The latest emissions compliant specification has resulted in higher power and torque in a smaller, lighter overall package that has become cheaper to run,” said Eric Neal, executive director of Cummins off-highway business. And, he added, “Cummins’ ability to tailor engine power and torque curves and make full use of our in-house equipment such

Cummins B6.7 and L9 engines are EU Stage V emissions certified

196 Cummins has announced that its latest B6.7 and L9 engines are fully EU Stage V emissions certified and in full production at its Darlington engine plant in the UK.

“The latest emissions compliant specification has resulted in higher power and torque in a smaller, lighter overall package that has become cheaper to run,” said Eric Neal, executive director of Cummins off-highway business.

And, he added, “Cummins’ ability to tailor engine power and torque curves and make full use of our in-house equipment such as turbochargers and exhaust after-treatment packaging, is enabling OEM’s to be more competitive.”

Top rated power for the B6.7 has increased to 243kW, with a peak torque of 1375Nm representing an increase of 30% over that achieved at EU Stage IV levels. The larger L9 engine has increased from 291kW up to 321kW, together with a 13% increase in peak torque, to achieve 1846Nm.

“The higher capability of these engines is delivering down-sizing opportunities for our equipment manufacturers,” he said.

    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

    January 6, 2017
    Cummins used bauma to reveal the QSF3.8 – a four-cylinder engine platform delivering a power range of 63-89kW – which is ready to meet Stage IV/Tier 4 Final emissions regulations. Using only SCR for its exhaust after-treatment process, the QSF3.8 avoids the need for either DOC or DPF as a result of using a high-efficiency catalyst to convert oxides of nitrogen at lower exhaust temperatures while requiring only low doses of DEF, said the company.
