Cummins new NanoNetTM fuel filtration gives superior fuel cleanliness and enhances the durability of the MCRS system - an important advantage for engines required to operate anywhere in the world with varying fuel quality.

Deep Structural Strength

A new ductile iron block and an extended block skirt ensure the highest possible structural strength for the QSK95, improving its capability for multiple overhauls. An internal stiffening bedplate minimizes vibration.

A single-piece forged-steel piston provides exceptional durability and reuse capability at rebuild. All three piston rings use premium materials, with the top ring Plasma Vapor Deposition (PVD)-coated. The hardened power cylinder features midstop cylinder liners and dual piston cooling nozzles, contributing to reduced piston ring temperatures and increased wear resistance.

The stronger engine design of the QSK95 means more reliability in-service and less to rebuild at engine overhaul, considerably reducing total life cycle costs. The QSK95 will provide an exceptionally long life-to-overhaul, capable of achieving 1.7 million gallons and above of fuel consumed before overhaul, with the significant advantage of no mid-life intervention required.

Meeting Ultra-Low Emissions Standards

The SCR aftertreatment system is purpose-designed for the QSK95 to provide a highly flexible, installation package for Tier 4 Final and similar ultra-low emissions standards. Design space remains available within the aftertreatment system configuration for additional Particulate Matter (PM) reduction technology if required for specific applications.

Depending on the duty-cycle, the Cummins SCR system is capable of achieving fuel savings of 5 percent to 10 percent, together with a significant reduction in carbon dioxide (CO2) emissions. The SCR fuel savings are incremental to those already realized by the high-pressure fuel system, reducing the cost of operation by more than the cost of Diesel Exhaust Fluid (DEF) required for the SCR system.

By using Cummins SCR aftertreatment solution, the QSK95 avoids the need for an Exhaust Gas Recirculation (EGR) system on the engine to reduce Oxides of Nitrogen (NOx). This EGR-free approach avoids the inherent complexity of applying it to high-output engines and means that no compromise is made to serviceability. A further advantage is that no additional heat rejection is generated by the engine, avoiding both an installation cost and space impact.

Increased Uptime And Serviceability

The QSK95 is designed with more inherent reliability to ensure the highest possible uptime availability. The engine is configured to provide faster and easier servicing procedures, with simple access to all cooling, oil and fuel system maintenance points on the engine. Service intervals are a minimum 500 hours, with the option of much-extended oil change intervals available using the ELIMINATORTM oil purification system, mounted on the engine.

The goal of a leak-free engine is achieved by premium "press-in-place" seals on all critical joints, such as flywheel housing, gear housing and oil pan-to-cylinder block. A special perimeter seal to the cylinder head guarantees that airborne debris cannot penetrate this important sealing interface.

Four standardized Cummins Electronic Control Modules (ECMs) provide a high level of processing power and memory to monitor, control and protect the engine systems. One ECM monitors each engine quadrant, with all four ECMs grouped together for easy access at the front of the engine in a protected cover. An easy interface provides access for full diagnostics.
