Cummins B6.7 reduces running costs and CO2 emissions

Published 10/5, 2021 at 14:26

Cummins Inc. has released the latest B6.7 ‘Performance Series’ engine that meets EU Stage V, and delivers near zero emission levels of NOx and PM.

It also features Stop-Start capability to help operators further reduce running costs, as well as their environmental impact, through lower noise and CO2 emissions.

Jeremy Harsin, Cummins Off-Highway business director said, “Stop-Start capability is included in the B6.7 to further cut fuel consumption as well as overall maintenance costs. Fuel savings should be between 5% and 10% but could be higher based on the machine duty cycle. This feature also delivers the sociability benefits that contractors   are looking for by reducing on site noise and exhaust emissions. Improving fuel efficiency reduces CO2 greenhouse gas emissions.”

Stop-Start has been integrated into the B6.7 platform with both hardware and software changes. Specially developed bearings in the engine, along with upgrades to the flywheel ring gear and starter motor ensure long life and reliable performance with frequent starts.  “Many machines sit idling on construction sites for long periods in between tasks. Stop-Start not only reduces running costs, it lowers running hours for the machine helping maintain higher residual values,” added Harsin.

The six cylinder B6.7 engine is available from 116kW-243kW with a high peak torque of 1,375Nm. With a low weight and compact size, it delivers a high power density that enables it to replace engines of higher displacement with no impact on machine operation. This supports machines needing higher speed power delivery, with low end torque capability for transient performance benefits. Equipment manufacturers can use the B6.7 to improve machine capability and offer more value to their customers.

This product is ideal for use in a range of off road equipment including crushers, screeners, wheel loaders, excavators, fork lift trucks, terminal tractors and empty container handlers. It can be tailored by Cummins’ engineers mechanically and electronically to each machine type. This powertrain integration capability delivers excellent all-around performance and running costs to match the required operating cycle.
