Cummins ultra-clean Stage V-compliant engines are now to be called Performance Series.

The engines are available from 3.8 to 15 litre displacement and 100hp to 675hp (75-503kW), and are designed to deliver solutions for material handling, construction and agriculture applications.

The European Commission's Stage V off-highway engine emissions legislation applies to all countries in the European Union. It came into effect from January 2019 for engines below 56kW as well as engines of 130kW and above, and will apply for engines from 56kW but below 130kW from January 2020.

“Cummins’ solution has achieved the near-zero emissions levels as demanded by Stage V,” said Alexei Ustinov, VP at Cummins off-highway engine business. "All our Stage V engines are in production, some of them ahead of the legislated date of January 2020. It is unclear what the plans are for off-highway emission regulations beyond this, so we have decided to rename these products to highlight what they bring to the market."

US-headquartered Cummins says that its 4-cylinder F3.8 and B4.5 Performance Series engines achieve "remarkable increases" in power and torque, giving manufacturers the opportunity to improve machine capability and offer more value to their customers. It adds that, alternatively, there is a potential to downsize the engine to one of lower displacement, reducing costs while preserving the productivity of their existing machines.

The 3.8-litre moves up from 130hp (97kW) to 173hp (129kW) with the new architecture, 33% higher. The 4.5-litre engine jumps 16% from 173hp (129kW) to 200hp (149kW). Peak torque of the F3.8 increases by more than 31%, to 620Nm, and an 11% increase moves the B4.5 up to 780Nm.

The F3.8 also features in Cummins HPP (Hybrid Power Plug-in) concept. Moving forward, Cummins says that it will offer full electric and diesel-electric solutions as part of a wide portfolio of power solutions. The HPP is designed to offer a balance of battery power with a compact engine-generator. It works in the same manner as a full electric driveline but has both an F3.8 Performance Series powered generator and plug-in options for charging. It is designed to give more flexibility where charging infrastructure is more challenging.

“The HPP solution lowers total emissions, with the opportunity to operate at zero or near-zero emissions during the shift," said Ustinov. "Noise and fuel consumption is reduced, using a smaller engine, operating for less time."

The 6-cylinder B6.7 Performance Series engine provides up to 326hp and a peak torque of 1375Nm – a 30% increase over its predecessor. The L9 9-litre Performance Series engine increases power from 400hp (298kW) up to 430hp (321kW), with a 13% increase in peak torque to 1846Nm.

“The higher torque capability of the Performance Series engines, particularly low in the rev range, makes them more responsive meaning the work gets done quicker which improves productivity,” added Ustinov.    

At the top of the range the X12 and X15 engines are designed to deliver heavy duty power from 335 to 675hp (250-503kW) for larger industrial equipment.

“All Performance Series engines are available as power units which are more than 70% pre-approved for installation including the engine, exhaust aftertreatment, cooling system, hoses, air cleaner and mounting,” Ustinov said.
