Cummins Stage V line up now named Performance Series
Cummins ISX15 Diesel Engine
“Cummins solution has achieved the near-zero emissions levels demanded by Stage V. 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. They are delivering more with less for our customers, more performance with lower installation costs for OEMs and lower running costs for operators. So, they will be called Performance Series moving forward,” said Alexei Ustinov Vice President - Cummins Off-Highway Engine Business.
The 4-cylinder F3.8 Performance Series engine achieve remarkable increases in power and torque, giving manufacturers the opportunity to improve machine capability and offer more value to their customers. 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 130 hp (97 kW) to 173 hp (129 kW) with the new architecture, 33 percent higher than Stage IV. Its peak torque also increases by more than 31 percent to 620 Nm, with torque at lower revs increasing 36% for improved machine output.
The 6-cylinder B6.7 Performance Series engine surges ahead with up to 326 hp and a peak torque of 1375 Nm – a 30 percent increase over its predecessor. It is suitable for a range of applications including fork lift trucks and empty container handlers.
“The higher torque capability of the Performance Series engines, particularly low in the rev range, makes them responsive and ideal for lifting heavy loads in the construction, material handling and agriculture markets,” added Ustinov.
The integration of Cummins Stage V Single Module™ aftertreatment system with leading combustion and air handling technology allows EGR to be removed from the F3.8, B4.5, B6.7 and L9 engines. The Single Module™ combines DPF, SCR and urea-dosing technologies in one unit, providing up to 40 percent reduction in envelope size and 20 percent reduction in weight compared to earlier products. This offers OEMs a simpler installation with lower installed costs.
Removing EGR offers additional benefits for equipment manufacturers. The same Cummins engine platform can be applicable for sales to multiple emissions standards, from Stage V and Tier 4 Final, all the way down to unregulated levels. Each machine can have the same electronic integration and mechanical hookups, with or without exhaust aftertreatment. This give installation commonality and manufacturing flexibility to OEMs, saving cost.
