CUMMINS SETS THE BAR FOR POWER DENSITY

01 March 2021

The Cummins Performance Series Engine Line-Up

Cummins ultra-clean Stage V four-cylinder Performance Series engines are the driving force for exceptional levels of power and performance in everything from telehandlers to tractors.

The F3.8 and B4.5 Performance Series engines, available from 74 to 675 hp (55 to 503 kW), achieve increases in power and torque for machines needing higher-speed power delivery, with low-end torque capability for transient performance benefits. Users also have the potential to downsize the engine in their machines, thereby reducing costs while preserving productivity.

Providing proven solutions for a range of industrial applications, the 3.8-litre F3.8 engine is available for 74 to 173 hp (55 to 129 kW), with a peak torque of 620 Nm. The 4.5-litre B4.5 engine is available from 120 to 200 hp (90 to 149 kW) with a peak torque of 780 Nm.


The integration of Cummins Single Module™ aftertreatment system with leading combustion and air handling technology enables these engines to meet and exceed Stage V ultra-low emissions levels without the need for cooled exhaust gas recirculation (EGR). The Single Module™ combines a diesel oxidation catalyst (DOC), a diesel particulate filter (DPF), and selective catalytic reduction (SCR) urea-dosing technology in one unit.

The Cummins B4.5 Performance Series Engine

Having no EGR means that both engines are simple, low weight designs, allowing for easier installation into equipment; together with lower cooling requirements, this further reduces installed costs. The simpler configurations also mean higher reliability, reducing the total cost of operation and boosting availability. Running costs are reduced with improved fuel efficiency and extended service intervals. Stop-Start capabilities can be integrated to further cut fuel consumption as well as overall maintenance costs, helping to reduce on-site exhaust emissions and noise. Fewer running hours for the machine also results in higher machine residual values.

The same Cummins engine platform can be applicable for sales to multiple emissions standards, from Stage V to unregulated levels. Each machine can have the same electronic integration and mechanical hookups, with minimal changes needed. This gives installation commonality and manufacturing flexibility to OEMs, saving on total costs. High sulfur tolerance up to 5,000 ppm without aftertreatment also supports the global capability of equipment. Cummins global manufacturing capability means engine platforms can be built where the customer needs them.

The Cummins F3.8 Performance Series Engine

These products are ideal for use in telehandlers, forklifts, rollers and compactors, skid-steer loaders, wheeled loaders, excavators, air compressors and agricultural tractors. They can be tailored by Cummins’ engineers mechanically and electronically to each machine type. This powertrain integration capability delivers the best all round performance and running costs to match the required operating cycle. In short, proven Cummins technology powering performance.
