Obtaining the benefits of today’s advanced diesel engine technology often means an original equipment manufacturer (OEM) has to extensively re-engineer their product to accommodate the new powerplant. The time and expense involved can be a serious impediment to the timely adoption of today’s low-emission, power-dense and fuel efficient engines.
The Perkins® 904 Series family of Industrial Open Power Units (IOPU) is designed to meet this challenge. They are designed to provide agricultural and industrial customers with essentially ‘plug-and-play’ engines that often can be fitted to a broad range of new or existing equipment without major re-engineering or design changes.
Each new IOPU builds on the experience gained with its predecessors, with the two latest additions, the 2.8 litre 904J-E28T and 3.6 litre 904J-E36T, adding to our ‘plug-and-play’ offering.
The turbocharged 2.8 litre delivers up to 55 kW and 300 Nm of torque at 1600 rpm, while the larger and more powerful 3.6 litre turbocharged aftercooled offering has a maximum output of 100 kW and 550 Nm of torque at 1500 rpm.
“With a highly integrated design that’s ready to plug in to a range of machine types, the 2.8 and 3.6 litre models are designed to save customers’ time with a power solution that requires minimal re-engineering to integrate into their equipment,” explained Jaz Gill, Perkins vice president of global sales, marketing, service and parts.
“The IOPU is designed for those OEMs that wish to enjoy the advantages and advanced technologies of our engines with minimum re-engineering. As a plug-and-play solution, the IOPU is an ideal way to power these machines, as they are ready to go. These two new additions to our range mean we’re now able to offer customers a choice of IOPUs at the key power nodes from 15.1 kW up to 225 kW.”
The new engines are rated at 55 and 100 kW respectively and meet EU Stage V, U.S. EPA Tier 4 Final and Japan 2014 (Tier 4 Final) emission standards. As ‘plug-and-play’ solutions, the IOPUs come with full aftertreatment mounting, an integrated cooling system, full wiring harness and flexible mounting for the ECM and fuel filter to make them compatible with a wide range of machine types.
All of these standard features make the new 2.8 and 3.6 litre IOPUs exceptionally easy to integrate into either new or existing machines.
Engine mounted aftertreatment eliminates the need to engineer separate mountings and plumbing connections for the various aftertreatment components and makes the entire power package more compact.
The ECM can be flexibly mounted in different locations on the package to meet specific machine layouts and comes with a bespoke wiring harness that simplifies connection of the machine harness.
The fuel filter includes a water in fuel sensor. It is mounted to the IOPU and comes pre-connected to the fuel system from the factory which simplifies low pressure fuel system installation. Both standard and heavy-duty filter options are available to meet a full range of machine types and operating environments.
Like the aftertreatment system, the cooling package is fully integrated into the IOPU and validated to operate under a global range of conditions. The system can be specified with either pusher or puller fans and an erosion screen is available for applications in harsh environments. Heavy-duty cooling systems also are available.
An engine control panel for engine monitoring and speed control is available as an option which can significantly reduce the time and cost of developing machine controls.
The 3.6 litre IOPU can be configured for either 12 or 24 volt electrical systems.
Like all Perkins engines, the new 2.8 litre 904J-E28T and 3.6 litre 904J-E36T have been developed in close collaboration with Perkins’ customers to ensure that they meet the broadest possible range of application requirements within their power nodes. Both have been optimised to match the operating range of typical off-highway applications within those nodes to minimise fuel consumption.
Easy servicing and maintenance also were emphasised during engine development. They are, for example, equipped with hydraulic tappets that can reduce or eliminate the need for periodic adjustments and reliable multi-vee belts that deliver an extended service life and are easier to replace when necessary. The IOPUs also feature single-side service access and a 500 hour service interval, both of which contribute to low cost maintenance and ownership.
In the field, the new 2.8 litre and 3.6 litre IOPUs will be supported by the global network of Perkins distributors and dealers in 171 countries. Both OEMs and end users benefit from almost a century of engineering excellence, delivered by members of the Perkins network who are recognised for their exemplary standards and local expertise.
Diesel engine technology will continue to evolve, driven by the need to reduce emissions while delivering reliable power more efficiently. At the same time, environmental, social and corporate governance (ESG) issues will become increasingly important considerations for corporate decisions about the application of those engines.
The resulting need to meet these concerns by upgrading existing equipment and incorporating advanced engine technologies in new products is likely to place a premium on solutions like the Perkins 904 Series of IOPUs. Given the incredible diversity of global applications, the new 2.8 litre 904J-E28T and 3.6 litre 904J-E36T powered IOPUs are a significant step in that direction.
