QSK95 G-Drive engine delivers radically improved power capability for power generation applications. The QSK95 engine is one of the most advanced technology engines designed with the end user applications in mind to achieve cleaner and more efficient performance.  Featuring advanced technology fuel injection that works to deliver faster power delivery and combined with a quad-turbocharging system to boost transient response. As a result, the QSK95 G-Drive engine has the best in class transient performance, capable of meeting ISO G3 standards. 

With over 5050-hp (3767 kW) output from 16 cylinders, the QSK95 surpasses other high-speed engines. In terms of emissions capability and power density, the QSK95 is way ahead of much larger medium-speed engines with a similar output. Genset end users will find the QSK95 is a cost-effective and very dependable power solution.

The space-efficient design of the QSK95 enables easier service accessibility than is typical for engines of this output, as all key cooling, oil and fuel system components are externally engine mounted, providing rapid access.

CTT (Cummins Turbo Technologies) HE800 Turbochargers – Four turbocharging units utilize exhaust energy with greater efficiency for improved emissions and minimum fuel consumption.

2 Pump 2 Loop (2P2L) Cooling system – Provides the means to higher power density while still meeting emissions requirements.

Modular Common Rail System (MCRS) – Higher fuel pressures compared to other EPA Tier 2 engines allows for greater atomization of fuel, leading to better in-cylinder emissions control. 

High Pressure Fuel Pump with filter – Robust pumping element offers 2500 bar capability; filter is included to ensure clean oil to lube pump and pressure switch ensures adequate pre-lube levels. 

Combined Priming and Fuel Transfer Pump (Electronic) – Quickly primes low-pressure fuel system; minimizes flow rate through filters and improves filtration capability, mitigating flow surge effects.

G-Drive Integrated Design – Each component has been specifically developed and rigorously tested for G-Drive products, ensuring high performance, durability and reliability.

Service and Support – G-Drive products are backed by an uncompromising level of technical support and after sales service, delivered through a world class service network.

To protect public health and conserve our planet's natural resources, legislation from the U.S. Environmental Protection Agency (EPA) and regulatory agencies in the European Union (EU) has, for the past decade, required that pollutants produced by diesel engines - such as nitrogen oxides (NOx), hydrocarbons (HC) and particulate matter (PM) - be reduced.

Throughout this time, Cummins Inc. has been at the forefront of the move to meet these new standards, becoming:

  • the first manufacturer to introduce EPA Tier-4F and Tier-3 products to the market - ahead of the regulatory deadline;
  • the first manufacturer to introduce EU Stage V compliant generator-drive diesel engines to Europe;
  • the leader in innovative emissions solutions that focus predominantly on in-cylinder design improvements to eliminate most of the NOx, HC and PM before they are formed.

As a result, our diesel engines are not only very clean, but also retain all their performance advantages with and without the Cummins exhaust after treatment systems ensuring complicate maintenance for end users.

Cummins Power Generation provides the best warranty and extended warranty plan in the industry. You can expect Cummins Power Generation and its authorized warranty locations to:

  • Stand behind Cummins Power Generation products.
  • Repair all failures that are a result of defects in materials or factory workmanship by Cummins Power Generation, or arrange for OEM warranty service if component is from another manufacturer.
  • Provide the benefit of the coverage immediately.
  • Treat all customers fairly and consistently.
