The Intelligent Load Management System (ILMS) is now available as an option on new G190 to G325 Tier 4-Final generator models with plans to expand the option to other models in the Doosan Portable Power generator lineup.
Why is this option important?
Diesel generators equipped with Tier 4-Final engines require elevated internal heat to effectively complete diesel particulate filter (DPF) regeneration — an aftertreatment process that consumes particles and impurities in the exhaust stream in order to meet emission standards. Similarly, Tier 4-Final engine systems equipped with selective catalytic reduction (SCR) aftertreatment technology require higher exhaust temperatures for periodic conditioning of the SCR system to maintain efficiency and performance. Generators operating below rated capacity or in extremely cold environments often cannot produce the required internal heat. As a result, the process is often aided by adding supplemental load or employing a conventional load bank which requires downtime.
The Doosan Portable Power-patented ILMS creates supplemental heat within the exhaust system, which aids the regeneration process without limiting the generator capacity or causing downtime. The internally packaged ILMS adds a relatively small amount of load and applies the heat generated by the ILMS directly to the aftertreatment system. As a result, the ILMS is able to achieve the temperature threshold needed to ensure proper aftertreatment performance more efficiently than load bank systems. The ILMS is also more fuel efficient compared with other methods of adding supplemental load.
The ILMS option is currently available on the G190, G240 and G325 mobile generators.
