Cummins is introducing Stage V compliant variants of its B6.7 and QSK60 diesels. These will meet the new European regulations on exhaust emissions.

Of note for the B6.7 unit is that it offers an increase in torque of 30%, while maximum power is now 243kW. As a result of the performance increase, some users have been able to replace 9litre engines for some installations with the more compact 6.7litre unit. This boost in torque has come about following the removal of the EGR unit fitted to minimise emissions on previous generation engines for this capacity class from the firm.

Meanwhile the QSK60 represents a major step forward for Cummins also. This is the first engine in the higher power range designed to meet the latest emission standards, as this category was previously exempt.

Also new from Cummins is the Stage V F3.8 power unit. This is delivered as a complete and ready-made power package that comprises an engine, single module aftertreatment, radiator and cooling system.

The firm says it is well on track with the Stage V development programme and has 200 installations featuring this technology. Cummins now offers diesels that meet the Stage V requirements with power outputs from 75–503kW.
