The world is full of uncertainties, from weather predictions to economic forecasts. But you can always count on Cummins QSC-powered equipment to pull you through. Cummins QSC engines are built on one of the world’s most successful – and durable – engine block designs. In fact, there are over three quarters of a million in use around the globe every day.

The QSC advanced electronics provide enhanced engine performance with higher torque and better throttle response at every rpm. Electronic engine control provides additional advantages that include increased fuel economy, precision diagnostics and engine protection. And the impressive durability of the QSC is enhanced by long maintenance intervals, improved cold starting plus up to 50% quieter operation for improved operator comfort.

The QSC meets every Tier 3/Stage IIIA emissions standard without compromise. There’s no fuel economy penalty when compared to Tier 2 mechanical engines.

Plus, its in-cylinder solution is simpler than other alternatives, giving the QSC the capability to meet Tier 4/Stage IV emissions with the addition of aftertreatment. With its ideal combination of electronic controls and durable block design, the QSC is ready to meet every one of your toughest applications.

Features and Benefits

Standard features include:

Full-Authority Electronic Controls – Provide seamless integration with other components to optimize engine operation.
Stiffer Block and Head – For reduced noise and vibration. Fluid circuits are integrated, replacing hoses and eliminating potential leaks.
High Pressure Common Rail Fuel System – Allows multiple injection events for cleaner, quieter operation with consistent performance at every rpm. Also improves cold-weather starting.
Wastegated Turbocharger – Delivers maximum power and torque.
Mid-Stop Cylinder Liners – Reduce cavitation and improve rebuildability.
Auto-Tensioning Belt Drive – Self-adjusting for optimum tension, which increases fan, alternator and fan belt life.
Heavy-Duty Roller Followers – Cam roller followers give the QSC superior durability and cam life.
Two-Stage Dual Fuel Filtration – Provides a balanced level of particle separation to maximize fuel filter life and protect the vital fuel system components.
Gear Housing Design and Front-End Support – The gear housing and accessories mount directly to the block for improved durability.
Improved Piston Design – Symmetrical piston bowl combines with centered injectors to deliver optimal combustion.
Heavy-Duty Lube System – Targeted piston cooling and increased lube flow to the power cylinder result in increased piston reliability and durability. Improved lube and bypass filtration system increase ring and bearing life by as much as 63%.
Improved Crankcase Ventilation – Virtually eliminates oil carryover.
Valve Cover and Gasket – Isolated design with perimeter bolting for better sealing and improved reliability.
Options

12- or 24-volt electrical capacity.
Front-mount accessory drive option available for hydraulic pumps or air compressors.
Rear Engine Power Take-Off (REPTO) available for hydraulic pumps or air compressors.
Performance

The QSC 24-valve cylinder head, High Pressure Common Rail (HPCR) fuel system and robust electronic controls make for a completely programmable, highly durable, highly fuel-efficient power plant. With one of the highest power-to-weight ratios and lowest cost of operation of any engine in its class. And ratings that range from 215-305 hp (160-227 kW) to deliver the power and the versatility you need to match your equipment. Every time.

Every Installation

Getting every installation right – the first time – is as important to Cummins as it is to you. PowerMatch and Advisor help ensure that we get it right, every time.

Cummins Advisor

Getting every installation right is what Cummins Advisor is all about. Advisor puts a virtual engineer on the OEM team, allowing the OEM to focus on machine requirements instead of engine requirements. This shortens engineering cycle times and cost. Cummins Advisor models equipment installation for exceptional productivity, reliability and durability.

After a comprehensive review of load factors, climates, duty cycle and equipment usage, Advisor recommends the best engine and rating match for the equipment and operating conditions. It then builds a virtual model of the intake, exhaust, cooling, fuel and mounting systems.

When Advisor identifies an issue, it lists acceptable alternatives. This approach allows changes while the equipment design is still “on paper,” ensuring optimum performance while minimizing costs – every time.

Cummins PowerMatch

PowerMatch helps OEMs optimize engine performance so you can lower fuel consumption, increase operator satisfaction, improve equipment life and protect the customer’s investment. PowerMatch tailors engine performance to specific equipment models and applications. Advanced electronics are used to enhance power curves and trim ratings, matching the job the equipment will be doing while taking into account variables such as work environment, load factors, ambient temperature and altitude.

PowerMatch can also be used to create a unique torque curve, set up alternate torque curves, alternate governor settings or set up engine protection features.

Turn on the Boost Power feature, and the equipment user gets an extra burst of power needed to get through tough spots – but only for as long as needed – so fuel economy and durability are not compromised.

Because PowerMatch allows for immediate field–testing of new calibrations, application engineers can quickly develop the optimum calibration for every customer.
