The QSK50 engine paired with a Kato generator are the power behind the Cummins DPM rotating unit
Te QSK50 engine powering the rotating unit is rated at 1,500hp and is paired with a Kato M/N 4P8.2-2700, 600V/60Hz/0.7 PF/ oversized generator for drilling duty. Te control system offers integrated engine monitoring with satellite telematics. And the installation is the same footprint as the Tier 2 DPM. Te integrated 330 gallon bulk DEF system, provides as many as 15 days of runtime before DEF refill is needed. Larger bulk DEF solutions can be used, providing longer runtime before refill.
Te QSK50 offers many improvements over its
Tier 2 predecessor, including improved piston ring packs to reduce blow by, new piston bowl design to increase the mixture of fuel and air, and faster flame propagation for a more complete combustion. Additionally, ahead of each turbo charger is a fully variable valve wastegate that can either control PM by optimising air/fuel ratio under all engine conditions, or control the SCR inlet temperature to increase NOx removal efficiency and reduce DEF usage. Te high-pressure common rail (HPCR) system allows as many as four separate injections per combustion cycle, to ensure more efficient combustion. Improved fuel filtration with a synthetic nano fibre media catches sub-micron particles before they enter the into the engine’s fuel system. Support during the design, installation and operation of the rotating unit will be provided, to ensure the field trial of the DPM offers the customer a true sense of the operational experience. Based on its past experience with SCR and its
current success with Tier 4 Final in well servicing and drilling, Cummins believes that SCR technology is the right choice for the Tier 4 Final transition. l
