Hybrids and electrification

“Following a significant investment in hybrid engines and electrification research, we find ourselves in an excellent technology leadership position to help our valued OEMs develop the machines of tomorrow,” Jaz continued.   

With access to millions of hours of machine operating data, Perkins has identified that the operating cycles of real construction machines varies from one application to another, and as machine size increases. The duty cycles, operating conditions and packaging constraints for off-highway machines drive the need for specific configurations that are highly customised to the individual application. 

To provide the close technical collaboration required to meet customers’ needs, Perkins has established a dedicated team – the Perkins Expanded Offering Product Team, led by Tom Carlill, new product introduction programme manager.

“There isn’t one solution that fits all machines, so we’re focused on establishing ourselves as an integrator with multiple hybrid and electric power technologies,” Tom said. “By working with us OEMs will achieve better project outcomes and deliver more productive, cost competitive and more relevant solutions for their markets. By sharing our advanced tool set, skilled team and excellent facilities OEMs will achieve these superior results quickly and at the lowest cost.”

At Plantworx, Perkins is highlighting three hybrid power solutions through three engines, all at 75 kW (100 hp). To demonstrate modularity and flexibility, all three hybrid solutions are based on the Perkins® Syncro 2.8 litre. 

The three technologies on show are:   

• Hybrid-electric: There are several ways to incorporate the electric motor or generator, with Perkins preferred arrangement delivering excellent fuel saving benefits while moderating the installation impact and minimising the cost impact on the machine. The flexibility of the system provides opportunities for further efficiency and functionality improvements in the whole machine through use of 48-volt electrics. 
• Hybrid-mechanical: This stores energy in a high-speed flywheel which can be delivered back to the machine. This is particularly useful in hybridising machines that run a cyclic operation and need very intense bursts of additional power. Apart from the very quick energy release, the advantage over hybrid electric is in installation size.
• Hybrid-hydraulic: This stores energy in hydraulic accumulators. In some machines this can be the most practical and cost-effective hybrid solution as it easily integrates into existing machine hydraulic systems. Software and integration of machine systems are key to achieving great savings from this technology.

Perkins is offering hybrid and electric technologies across its Stage V power range from 8.2 to 597 kW (11 to 800 hp). 

Proven performance

Perkins Stage V engines have been designed with OEMs profitability in mind. Offering market-leading power density our Stage V engines are quick and simple for OEM’s engineering teams to install, saving time and money at every stage.

At Stage V, uplift in power and torque performance across the 0.5 to 18 litre range has improved in three main ways. Power density – the amount of power you get from a particular package size, has increased by up to 28 percent. Torque meanwhile, has increased by up to 29 percent and significant fluid consumption – namely fuel and diesel exhaust fluid (DEF) improvements, have also been made across the range. All of these mean that OEMs can downsize and reduce cost without compromising on performance. 

At Plantworx Perkins is showcasing a range of engines that meet the new Stage V emission standards.

• With a power output of 19 kW (25 hp) the 403J-17T is a compact turbocharged engine delivering 24 percent more power and an impressive 166 Nm of torque – that’s 34 percent more when compared to its predecessor, enabling users to easily downsize.
• The new Perkins® Syncro 3.6 litre offers power up to 100 kW (134 hp), excellent peak and low speed torque and economic fuel consumption. Its compact design enables OEMs to optimise machine layout, while operators will benefit from a quiet engine, after a reduction in noise of 3 decibels at full power.
• The new 1204J-E44TA/TTA is a 4-cylinder, 4.4-litre capable of multiple power ratings from 82–150 kW (110-201 hp) with peak torque reaching 825 Nm. The new engine offers significant machine productivity benefits with 15 percent increase in power, 10 percent more torque and 5-10 percent reduction in fuel consumption.
• At the larger end of the Perkins range, the 1706J-E93TA is a 6-cylinder, 9.3 litre engine providing 19 percent more power and improved torque up to 340 kW and 2088 Nm. With a fully configurable options list, a compact and lightweight aftertreatment and no exhaust gas recirculation (EGR) the 1706J offers high performance in a simple and flexible design.
